Ukuvikelwa Kokuvikeleka Kwedivayisi ye-SPD yamalambu e-LED, amalambu, izibani, iLuminaire

ISIDINGO SOKUVIKELWA

Kungani kudingeka ukuvikelwa?

Ubuchwepheshe be-LED sebuyisethenjwa sobuchwepheshe bokukhanyisa, ikakhulukazi ngenxa yezici ezine: ukusebenza kahle, ukwenza izinto ezihlukahlukene, ukonga amandla nempilo ende.

Ngaphandle kwalezi zinzuzo, ubuchwepheshe bunezithiyo eziningi: Izindleko eziphakeme zokuqalisa (ukutshalwa kwezimali kokuqala) kanye ne-elekthronikhi yangaphakathi (ama-optics e-LED kanye nabashayeli), kuyinkimbinkimbi kakhulu futhi kuyazwela kuma-overvoltages kunasesimweni semithombo yendabuko yokukhanya.

Ngenxa yalezi zizathu, ukusetshenziswa kwezinhlelo zokuvikela ukukhokhelwa kwamandla okutshalwa kwemali kungukutshala imali okungabizi kakhulu, ngoba kwandisa impilo yamalambu, kuqinisekisa ukusebenza kwezindleko (i-ROI) yamaphrojekthi we-LED futhi kunciphise nezindleko zokulungiswa kanye nokushintshwa kwamalambu.

Idivayisi yokuvikela ukuqhuma (i-SPD) exhunywe ngenhla komshayeli, igcwalisa ukuvikeleka kwangaphakathi kwesibani, kudale ukuvikelwa okuqinile kakhulu emiphumeleni yombani nokuqhuma kwamandla.

Uhlolojikelele

Ama-luminaires anobuchwepheshe be-LED asetshenziswa enombolweni enkulu yezinhlelo zokusebenza lapho ukutholakala okuphelele ezimweni zasemkhathini kuvame ukuphakama: ukukhanyisa emgwaqweni, imigudu, ukukhanya komphakathi, izinkundla zezemidlalo, izimboni, njll.

Ama-overvoltages angahlukaniswa abe izinhlobo ezi-5 ezihlukile
1. Amandla enyuka womhlaba ngenxa yesimangalo esiseduze, ngokuya ngobunzima bomhlaba obonakalayo.
2. Ukushintsha ngenxa yokusebenza okujwayelekile. (isib. zonke izibani ezikhanyiswayo ngasikhathi sinye).
3. Kubangelwe ukujikeleza: okuvela kunkambu ye-electromagnetic yesiteleka esiseduze (<500 m).
4. Isiteleka esiqondile kulayini wokukhanyisa noma wokunikezela.
5. Ukuqubuka okungapheli noma okwesikhashana (POP) ngenxa yezinkinga zokunikezela

Amathuba wokuqhuma kwamandla okubangelwa isiteleka sombani noma ukufakwa imvamisa aphezulu kakhulu ekufakweni kokukhanyisa, yize ingozi inqunywa uhlobo lokufakwa (ngaphakathi, ngaphandle) nezinga lokuchayeka (izindawo eziphakeme, amasayithi angawodwa, ikhebuli izandiso, njll.).

Ukulimala nezindleko zokulungiswa

Abashayeli bavame ukuba nezinga elithile lokuzivikela (2 kuya ku-4 kV) kuma-overvoltages wesikhashana. Lokhu kwanele ukudlulisa ukuhlolwa kwama-luminaires kepha akwanele ukumelana nokuqubuka kwamandla kagesi okubangelwa umbani (10 kV / 10 kA) ngaphansi kwezimo zensimu.

Okuhlangenwe nakho kwesisekelo esifakiwe embonini yokukhanyisa i-LED kukhombisile ukuthi ngaphandle kwe-SPD efanele, amaphesenti aphezulu wezikhanyiso afinyelela ukuphela kwempilo ngaphambi kwesikhathi. Lokhu kuholela ezindlekweni eziningi zokushintshwa kwemishini, izindleko zesondlo, ukuqhubeka kwensizakalo, njll okugcina kuthinte kabi ama-ROI wephrojekthi nesithombe sawo.

Ukuqhubeka kwensizakalo kubalulekile ekufakweni kokukhanyisa lapho ukukhanya okuhle kuyinkinga esemqoka yezokuphepha (ubugebengu, ukuphepha emgwaqeni, ukukhanyisa emsebenzini, njll.).

Ubungako obufanele besistimu ye- “SPD + luminaire” buqinisekisa ukuthi izehlakalo zokuphindaphindeka kwamandla okuphindaphindeka aziholeli ekugcineni kwempilo yomshayeli, noma cha ngaphambi kwe-SPD esimweni esibi kakhulu. Lokhu kuguqulela ekongeni izindleko, ikakhulukazi ngenxa yokwehliswa kwezenzo zokulungisa.

Ukuvikelwa okuphelele

Amadivayisi wokuvikela (i-SPD) avikela imishini ngokukhipha amandla okuvota emhlabeni, ngaleyo ndlela anciphise amandla wevolumu afinyelela okokusebenza (amandla asalayo).

Idizayini ephumelelayo yokuvikelwa kwamandla okuvota ihlanganisa ukuvikelwa okumile, kunezigaba zento ngayinye ebucayi ohlelweni. Ngale ndlela ingxenye yevivili ekhishwayo iyakhishwa esigabeni ngasinye sokuvikela kuze kube yilapho kuphela amandla amancane asalayo asele eduze kwesibani.

Ukuvikelwa kuphaneli yokukhanyisa "1" yize kunesidingo, kukodwa akwanele ngoba ama-overvoltages nawo angafakwa ekugijimeni kwekhebula elide, okusho ukuthi ukuvikelwa kokugcina kufanele ngaso sonke isikhathi kusondele ngangokunokwenzeka kwimishini evikelwe "2" "3" .

IZIMISO EZISEMQOKA ZOKUVIKELWA KAKHULU

Ukuvikelwa kwe-Cascade

Indawo yokuvikela

Ukuhlelwa okujwayelekile kokufakwa kwangaphandle kokukhanyisa kuqukethe iphaneli yokukhanyisa ejwayelekile kanye neqoqo lamalambu anezintambo ezinde ezisebenza phakathi kwawo, naphakathi kwawo nephaneli.

Ukuze uvikeleke ngempumelelo ohlelweni olufana nalolu, kubalulekile ukuthi ube nokuvikelwa okumile ngamandla amakhulu okukhipha kanye namandla kagesi asele aphansi. Lokhu kudinga okungenani izigaba ezimbili zokuvikelwa (bona ithebula).

Ukuvikelwa - ochungechungeni noma ngokufana

Amadivayisi wokuvikela (i-SPD) angaxhunyaniswa ochungechungeni noma ngokufana njengoba kukhonjisiwe esithombeni. Ngayinye inezinzuzo nezinkinga zayo

• Ukufana: uma i-SPD ifinyelela esiphethweni sempilo isibani sizohlala sixhumekile, sinikeze kuqala ukuqhubeka kwensiza.
• Series: uma i-SPD ifinyelela esiphethweni sempilo isibani sizocishwa, kunikezwe ukuvikelwa kuqala. Lokhu kuxhumana kunconyiwe ngoba kwenza ukuthi ukwazi ukwazi ukuthi ngabe ikhona yini i-SPD efinyelele ekupheleni kwayo. Lokhu kugwema ukuthi uvule isibani ngasinye ukuhlola isimo somboshwa.

Ukuphepha kanye nendawo yonke

Ukuphepha kanye nendawo yonke kuyizinkinga ezibalulekile ekwakhiweni nasekufakeni i-luminaire, ngoba lokhu kunikeza induduzo nokuthula kwengqondo kumfakisi noma i-specifier / iklayenti. Njengoba umenzi kaningi engazi ukuthi isibani sifakwe kuphi noma kanjani, i-UNIVERSAL, SAFE SPD kuphela enikeza isiqinisekiso sokusebenza okufanele kuzo zonke izimo.

I-luminaire ifakwa kanjani?

• Izinga (IEC 60598), lidinga ukuthi kungabikho sikhathi empilweni yayo lapho i-SPD ikhiqiza imisinga yokuvuza. Ukufeza lokhu, kusetshenziswa into ebizwa ngethambo lokukhipha igesi (GDT), elingakulungele ngokwalo ukuxhumana kwe-Line- PE. Njengoba ukuxhumana kwe-L-PE kubalulekile ekuphepheni nakwindawo yonke yama-SPD, isixazululo ukusebenzisa isekethe yokuvikela ehambisanayo ukuze kwimodi ejwayelekile i-SPD ihlale ine-varistor (MOV) ochungechungeni ne-GDT kuya e-PE.
• Amaphutha entambo. Ukuguqula i-L ne-N kuyiphutha elijwayelekile elingadala ingozi kagesi esimweni sokukhuphuka kodwa elingatholakali ngesikhathi sokufakwa.
• Intambo ye-SPD ochungechungeni noma ngokufana. Ukuyekethisa phakathi kokuqhubeka kwensizakalo nokuvikelwa kwesikhanyiso. Kungenxa yekhasimende lokugcina okufanele linqume.

Kufakwa kuphi ukukhanya?

• Amanethiwekhi we-IT, TT, TN. I-SPD ejwayelekile ayikwazi ukumelana nephutha lomugqa kumhlaba kumanethiwekhi we-120/230 V.
• Amanethiwekhi we-230 V LN noma we-LL. Lawa manethiwekhi ajwayelekile ezifundeni nasezimweni eziningana, akuwona wonke ama-SPD angaxhunywa ku-LL.

Ukuvikelwa kwe-POP

Ama-overvoltages wesikhashana noma unomphela (i-POP) akhuphuka kumandla kagesi angaphezu kwama-20% wamandla kagesi afinyelela ku-400 V amasekhondi, imizuzu noma amahora ambalwa. Lokhu kuqhuma ngokweqile imvamisa kungenxa yokwehla kokungathathi hlangothi noma imithwalo engalingani. Ukuphela kwendlela yokuzivikela emicimbini enjalo ukunqamula umthwalo, kulokhu ngokusebenzisa oxhumana naye.

Ukuvikelwa kwesikhashana kokuvota kwamandla - i-POP, ingeza inani ekufakweni:

• Ukuxhuma kabusha okuzenzakalelayo nge-contactor kuphaneli yokukhanyisa.
• Ukugoba ijika ngokuya nge-EN 50550.

Lesi sixazululo somhlaba wonke sisekela konke ukucushwa kwenethiwekhi (i-TN, i-IT, i-TT) namakilasi wokukhanyisa nge-luminaire (I & II). Leli banga lifaka uchungechunge lwezixhumi, ukulungiswa okuguqukayo nokukalwa kwe-IP66 okukhethwa kukho.

Quality

Isikimu se-CB isitifiketi (esikhishwe ngu- I-TUV Rhineland) kanye nomaka we-TUV lapho wonke amaphuzu e-IEC 61643-11 ne-EN 61643-11 ahlolwe khona.

Izixazululo zomhlaba wonke

I-SLP20GI iqinisekisa ubuningi nokuphepha kwesikhanyiso:

• Kakho konke ukumiswa kwenethiwekhis (TT, TN & IT) ukucushwa.
• Ukuphepha kwentambo I-LN / NL ibuyiselwa emuva.
• Ubuningi I-LN 230 V, LL 230 V
• Uchungechunge / ukufana izintambo.

Inkomba yokuphela kokuphila ephindwe kabili

Ukunqanyulwa Uma ifakiwe ochungechungeni, i-SPD izocima ukukhanya uma kukhulunywa ngokuphela kwayo.

I-LED ebonakalayo inkomba.

Akukho ukuvuza kwamanje

Yonke i-SLP20GI enokuvikelwa kwemodi ejwayelekile ayinayo imisinga yokuvuza emhlabeni, ngaleyo ndlela ivimbela noma yikuphi okungenzeka ukuthi i-SPD ikhiqize izintambo zokuxhumana eziyingozi.

ISICELO

Izinhlobonhlobo zezicelo zokukhanyisa, okuthi ngohlobo nokusetshenziswa kwazo, zenze ukuvikeleka ngokweqile kudingeke kakhulu. Ukuvikelwa okuhle kuqinisekisa ukusebenza kohlelo (ukuqhubeka kwensizakalo), kunikeza ukuphepha futhi kusiza ukuvikela utshalomali (i-ROI) kwimishini yokukhanyisa ye-LED.

KUNGANI UKHETHA LSP?

I-LSP, inkampani evikela umbani kanye nokuvikela abashayeli, inika imakethe uhla oluthile lokuvikela ukufakwa kwe-LED, umphumela wesipiliyoni seminyaka engaphezu kwengu-10 kulo mkhakha.

Umlingani wakho wokuvikela

Sihlose ukuba nguzakwethu ekuvikeleni ngokweqile, sinikeze isisombululo esiphelele kulo mkhakha: ububanzi bemikhiqizo, izeluleko ngezobuchwepheshe.

Umbani nokuvikelwa kokukhanya kwe-LED Lighting / isibani somgwaqo se-LED

Izixazululo ezihamba phambili zokuvikela ukukhanya kwe-LED ngungoti wezokuvikela

I-LSP, ongoti ekuvikelweni kombani nokuvikelwa kwamandla

I-LSP iyiphayona ekwakheni nasekukhiqizeni amadivayisi wokuvikela umbani kanye nokuqhuma. Sekuyiminyaka engaphezu kwengu-10 i-LSP ihlinzeka ngezixazululo ezisezingeni eliphakeme nemikhiqizo isebenzisa ubuchwepheshe bamuva obusha kakhulu.

I-LSP inikeza izixazululo ezahlukahlukene zazo zonke izinhlobo zemishini yokukhanyisa yangaphandle nokufakwa, ngaphakathi kwepali noma ngaphakathi kwephaneli.

Kungani uvikela

Ubuchwepheshe be-LED buhlanganisa umqondo wokusebenza kahle, kuhlanganisa ukonga amandla okukhulu kanye nesikhathi sokuphila esikhulu kakhulu kunemithombo yokukhanyisa yendabuko. Lobu buchwepheshe, noma kunjalo, bunezithiyo eziningi:

- Ukuqaliswa kwayo kudinga utshalomali olukhulu, uma kwenzeka kucekelwa phansi imishini kuzodingeka iphindwe.

- Ukuzwela ngokweqile kuma-overvoltages, noma ngabe kubangelwa umbani noma ngokushintsha igridi. Ubunjalo bokufakwa kokukhanyiswa komphakathi, ngezinsimbi zayo ezinde ezisebenza ngamakhebuli, kukhulise ukuvezwa kwabo kumiphumela yevoltage ebangelwa umbani.

Ngalezi zizathu, ukusetshenziswa kwezinhlelo zokuzivikela kuma-surges kungukutshalwa kwemali okunenzuzo enkulu, zombili ngokuya ngempilo yesikhanyiso nasekugcinweni kwezindleko zokufaka esikhundleni nokunakekelwa.

Izixazululo ze-OEM (umkhiqizi)

Nweba impilo yezinkanyiso zakho ze-LED futhi uvikele izimangalo ezingaba khona nomonakalo esithombeni sakho

Ukuvikelwa kokukhuphuka kunezela inani kumenzi wokukhanyisa kwe-LED, kunikeze isiqinisekiso esengeziwe kumsebenzisi wokugcina ngokuya ngokuthembeka nokuqina.

I-LSP, inkampani egxile ekuvikeleni ukuqhuma, inika umenzi isisombululo esiphelele kulo mkhakha: amadivayisi anhlobonhlobo wokuvikela abagibeli, izeluleko ngezobuchwepheshe, imikhiqizo eyakhelwe ukuhleleka, ukuhlolwa kwamalambu, njll.

Abanye abakhiqizi bezibani zangaphandle ze-LED sebevele bavikelwe yi-LSP

Ububanzi be-SLP20GI, i-Compact futhi kulula ukuyifaka kunoma iyiphi i-luminaire

I-LSP idale isixazululo esihlangene esilingana nanoma iyiphi i-luminaire. Ukuvikelwa kokuqubuka kwezikhanyiso ze-LED KULULA KAKHULU UKUFAKA. Izintambo, ama-terminals, njll.… Kungenzelwa umkhiqizi ngamunye.

Izixazululo zazo zonke izinhlobo zamagridi kagesi

Ububanzi babavikeli bokunyuka kwezikhanyiso ze-LED bufanele konke ukucushwa kwenethiwekhi nayo yonke imishanguzo (kufaka phakathi amasistimu we-IT). I-LSP inezixazululo zesikhanyiso seklasi I nesigaba II.

Ucwaningo lwakamuva lukhombisa ukuthi ngaphezulu kwamaphesenti angama-80% wamaphaneli akhanyayo womphakathi akhona ngaphandle kokuvikelwa kokuqhuma. Okwama-20% asele, ukuvikelwa kuphaneli akwenele ukuvikela ngempumelelo umhlangano we-luminaire oxhunywe kuphaneli, ngoba ama-surges nawo angadonswa lapho kuqhutshwa ikhebula elide.

Uhlelo olulungile futhi olusebenzayo kakhulu lokuvikela luhlobo oluntengantengayo noma lwe-cascade. Okokuqala, kufanele kufakwe isigaba sokuqala sokuvikela kuphaneli yokukhanyisa (ngokufakwa kwesivikelo esiqinile esinamandla amakhulu okukhipha ama-40 kA, kanye nokuvikelwa ekuvuthweni kwemvamisa yamandla we-TOV okweqile kwesikhashana) nesigaba sesibili esiseduze ngangokunokwenzeka i-luminaire (ukuvikelwa okuhle ukugcwalisa isigaba sokuqala).

Kulinganiselwa ukuthi kunesisekelo esifakiwe samalambu we-LED angaphandle angavikelwe ngokunganele e-Europe.

Ukwenza ngcono isisekelo esifakiwe samalambu e-LED ngokuvikelwa kokuqhuma kungukutshala imali okunenzuzo enkulu, zombili ngokwezindleko ezincishisiwe zokulungisa, kanye nokuvikelwa kwezimali ezibizayo.

I-LSP inikeza izixazululo ezahlukahlukene zokuvikelwa kahle kokufakwa kwangaphandle kwe-LED.

Ukuvikelwa okuhle

• kunciphisa izindleko zesondlo
• kuqinisekisa ukuqhubeka kwensiza
• kunweba impilo yamalambu
• iqinisekisa i-ROI kubuchwepheshe be-LED

Ukuvikelwa kwabashayeli be-elektroniki ababucayi namalambu e-LED ngaphakathi kwamalambu emigwaqo, i-LSP manje isungule isiboshwa esenziwe ngomthungo.

Amandla okonga amalambu e-LED asetshenziswa njengokukhanyisa emigwaqweni aya ngokuya ethandwa kakhulu. Kepha izingongolo zabo ezimile zisengozini ngezindlela ezimbili: Kusuka kombani nasezikhungweni ezikhuphuka ngamandla. Ukuvikelwa kwabashayeli be-elektroniki ababucayi namalambu e-LED ngaphakathi kwamalambu emigwaqo, i-LSP manje isungule isiboshwa esenziwe ngomthungo. Uhlobo lokuboshwa okungu-2 + 3 SLP20GI lunezinga eliphezulu lokuqhuba amandla angafika kuma-20 kA. Ukuba nezinga lokuvikela eliphansi kakhulu (U_P), ibuye ilungele ukuvikelwa kwezinto ezibucayi kakhulu ze-elektroniki. Ngenxa yokwakhiwa kwayo okuhlanganisiwe, izindlu zingafakwa endaweni yokuphela kwepali noma ekhanda lesibani somgwaqo. Ababoshwe i-SLP20GI bafeza izidingo zamadivayisi wokuvikela we-T2 + T3 ngokuya nge-EN 61643-11: 2012 evamile yomkhiqizo.

Ukuvikelwa Kokuqubuka Kumalambu E-LED

Amalambu angaphandle athinteka kuma-spikes wesikhashana ngenxa yeziteleka zombani ezihlanganiswa ngentambo kagesi. Ukuqubuka kungabangelwa umbani oqondile, umbani ongaqondile noma ukucisha / ukuvulwa kokuhlinzekwa kwamapayipi.

Ngaphandle kwama-surges, uma ulayini we-HV uthinta umugqa we-LV noma uma uxhumano olungathathi hlangothi lubuthakathaka noma luntanta isigaba- Izilinganiso ezingathathi hlangothi zingaya phezulu kunemikhawulo ebekiwe ye-luminaire. Ngenhloso yalesi sihloko sizogxila ekuvikelweni kokukhuphuka.

Lezi zikhathi zamandla kagesi ezikhuphukayo zingabhubhisa ukunikezwa kwamandla we-LED kanye nama-LED uqobo. Ngenxa yesimo esibucayi sezibani ze-LED, sidinga ukuhlinzeka ngaphezu kwamandla kagesi, ngaphezu kwamanje, ukuvikelwa kokuqina kwezinhlelo zokukhanyisa i-LED, Uhlobo oluvame kakhulu lwesivikeli sokuqhuma luqukethe into ebizwa nge-metal oxide varistor noma i-MOV, ehambisa amandla ombane angaphezulu amandla kude nedivayisi eliyivikelayo. Uma kunamalambu we-LED, izovikela i-LED Driver noma i-LED uqobo.

I-LSP inikeza amamojula we-SPD azonikeza ukuvikelwa okweqile kwe-10kV-20kV. Lokhu kuvikelwa kukhona phakathi kweSigaba-Esingathathi hlangothi, Isingathathi hlangothi-Umhlaba & Isigaba-Somhlaba. Sinikeza lawa ma-module akhiwe ngaphakathi kwezikhanyiso zangaphandle ezifana namalambu omgwaqo, amalambu ezikhukhula njll.

Ukuvikelwa Kokukhanya Kwamalambu Emigwaqo Ye-LED

Kufakwa amalambu emigwaqo emisha nasemigwaqeni emikhulu nokufakwa kwezinkanyiso ezijwayelekile ngoba ama-LED asebenzisa amandla amancane futhi anikela ngempilo enhle. Ukufakwa komphakathi kwangaphandle kuvezwe kakhulu emvelweni futhi kutholakala lapho insizakalo eqhubekayo ibalulekile. Yize kunezinzuzo eziningi zamalambu e-LED kepha inkinga eyodwa enkulu yama-LED ukuthi izindleko zawo zokulungisa nokufaka ezinye izinto ziphakeme kakhulu kunalezi ezikhanyayo ezijwayelekile futhi ama-LED athinteka kalula ngama-surges. Ukugwema ukunakekelwa okungadingekile nempilo ende, kufanele ufake iSurge Protection for LED Street Lights.

Amalambu emigwaqo akhanyisiwe athinteka ngama-surges ngenxa yezimbangela ezingezansi kwezimbangela ezinkulu:

1. Isiteleka sombani, isiteleka sombani ngqo ekukhanyeni komgwaqo we-LED. Izintambo eziseduze kakhulu zokusabalalisa ugesi zingaphandle kweziteleka zombani futhi umsinga omkhulu ungenziwa ngezintambo zikagesi ngenxa yombani, odala amalambu emigwaqo.
2. Isiteleka sombani esingaqondile sidala ukuphazamiseka kulayini wokuphakela.
3. Ukuqhuma kwamandla kagesi aphezulu kusuka kulayini wamandla, kusuka ekusebenzeni kokushintsha, izinkinga zomhlaba njll.

I-Voltage Surge iyi-High Voltage Spike ephezulu kakhulu yama-Kilo-Volts amaningana, okwesikhashana esincane kakhulu, ama-microsecond ambalwa. Kungakho udinga Ukuvikelwa Kwokwenyuka Kwezibani Zasemgwaqweni ze-LED.

Abakhiqizi abaningi be-LED nabanikezeli bempahla bayabona ukuthi uma amalambu emigwaqo e-LED eshaywa ukuqhuma, izinto ezahlukahlukene okungukuthi ukunikezwa kwamandla, ukunikezwa kwamandla kagesi, amashipsi we-LED ngisho nangesinye isikhathi imodyuli ephelele ilimele futhi kumele ithathelwe indawo futhi inqubo yokukhipha isibani esikhwameni inzima kakhulu inqubo. Yize ochwepheshe embonini yokukhanyisa becwaninga kakhulu ngale nkinga futhi bathuthukisa abanye abashayeli abanamandla aphezulu we-dielectric; kodwa laba bashayeli babiza kakhulu futhi kusekhona ithuba elifanele lomonakalo uma kwenzeka kuqhuma. Futhi lokhu kuchaza ukubaluleka kokuvikelwa kokukhuphuka kwamalambu emigwaqo aholelekile.

Ukutshala imali encane ekuvikeleni kunganweba isikhathi seLights Street futhi kunciphise izindleko zokusebenza nengqalasizinda

Manje umbuzo uvela ukuthi, singakunikeza kanjani ukuvikelwa kokukhuphuka kwamalambu e-LED Street? Lokhu kungenziwa ngokufaka amadivayisi wokuzivikela abizwa ngokuthi ama-surge arrestors kulayini omkhulu bese uwaxhuma ochungechungeni noma ekumisweni okufanayo. Uma ixhunywe ngokufana, ukukhanya kwe-LED kusazosebenza uma idivayisi yokuvikela ukuqhuma yonakele ngenxa yokuxhuma okufanayo.

Idivayisi yokuvikela ukwenyuka (i-SPD) izosebenza njengoshintshi olawulwa ngamandla kagesi ozohlala ungenzi lutho kuze kube yilapho uhlelo lwamandla lungaphansi kunamandla alo okuvula. Lapho isistimu (i-voltage yokufaka uma kwenzeka izibani zomgwaqo ze-LED) inyusa amandla we-SPDs activation, i-SPD izophambukisa amandla wokuqapha avikele ukukhanya. Umbani ubaluleke kakhulu lapho ufaka ama-SPD, khetha idivaysi engakwazi ukumelana namandla amakhulu wokucindezela.

Ukufakwa kokuvikelwa kokukhuphuka kwamalambu emigwaqo aholelwe:

Ngezansi kwesibalo bonisa izindawo lapho kungafakwa khona amadivayisi wokuvikela ukuqhuma kumalambu e-LED emgwaqweni:

1. Ngqo ekukhanyeni komgwaqo, kufakwe ngaphakathi kwekhabethe lomshayeli.
2. Kufakiwe ngaphakathi kwebhodi lokusabalalisa.

Ibanga phakathi kwensimbi yokuvikela ukukhanya nokuqhuma kufanele ligcinwe liphansi ukuqinisekisa ukuvikelwa okufanele, kufanele ligcinwe lifushane ngangokunokwenzeka. Uma ibanga eliphakathi kwebhodi lokukhanya nelokusabalalisa lingaphezu kwamamitha angama-20, ukusetshenziswa kwensiza yokuvikela yesibili kuyanconywa ezimweni eziningi.

Amazinga we-IEC Wokuvikelwa Kwokwenyuka: Ngokusho kwe-IEC61547, yonke imikhiqizo yokukhanyisa yangaphandle kufanele ivikelwe kuma-surges afinyelela ku-2kV ngemodi ejwayelekile. Kepha kunconywa ukuvikelwa kokukhuphuka kuze kufike ku-4kV. Ngenxa yezimbangela ezishiwo emazingeni okuvikelwa kwamazwe omhlaba, imbangela ethinta amalambu emigwaqo angaphandle isiteleka sombani esiqondile emigqeni yokusabalalisa (ukuqhuma okwenziwa ngezintambo zikagesi). Indawo yokufaka kufanele ihlolwe kahle futhi ifinyelelwe ukuthi kungenzeka yini iziteleka zombani futhi amathuba esiteleka sombani aphezulu, kunconywa ukuvikelwa kwe-10kV.

Ukuvikelwa kwamalambu e-LED ngokuvota ngokweqile

Izimbangela zokweqisa, okuhlangenwe nakho kanye nemiqondo yokuvikela

Umkhuba oqonde ekukhanyeni kwe-LED ekukhanyeni kwangaphakathi nangaphandle uyanda kancane. Okwamanje, iziphathimandla eziningi zendawo kanye nabasebenza ezinethiwekhi kulo lonke elaseYurophu banolwazi ngalobu buchwepheshe obusha. Kubukeka sengathi izinzuzo, ikakhulukazi maqondana nokonga amandla nokulawulwa kokukhanyisa okukhaliphile, zizoqinisekisa ukuthi isabelo sezixazululo ze-LED kubuchwepheshe bokukhanyisa sizoqhubeka nokukhula ngokuqinile ngokuzayo. Ekukhanyeni kwemigwaqo, lokhu sekuvele kubonakala emadolobheni amaningi, kepha ukuthambekela nakho kuyanda ekukhanyeni kwezimboni nokwakha. Kodwa-ke, nalapha kuyacaca ukuthi kukhona zombili izinhlangothi ezikhanyayo nezomthunzi.

Eminyakeni yamuva nje, sekuvele ukuthi ama-voltages ngokweqile ikakhulukazi abonisa inkinga enkulu ye-elektroniki ebucayi. Impendulo yokuqala evela emkhakheni iyakuqinisekisa lokhu. Ngokwesibonelo, idolobha lase-Esbjerg libike ukwehluleka okukhulu kunamanje kwamalambu emigwaqo angaphezu kuka-400 ngenxa yesiteleka sombani. Lokhu kufanele ukushiwo kakhulu njengoba iDenmark ingesinye sezifunda ezimpofu kakhulu zombani eYurophu.

Iziteleka zombani zingafinyelela amanani aphakeme kakhulu ngokuya ngebanga lendawo enomthelela, izimo zomhlaba nezimo zomhlaba nokuqina kwe-flash. Umdwebo 1 ukhombisa amandla wekhwalithi emalungeni okukhanya okukhanyisa emigwaqweni okubangelwe ukwakheka kofanele ongaba khona esitelekeni sombani.

Ngesikhathi sokushintsha ukusebenza kunethiwekhi, kukhiqizwa izintaba zamandla ezinkulungwane zama-volts ayizinkulungwane eziningana, ezisakazeka kwinethiwekhi yamandla aphansi futhi zilayishe eminye imishini.

Isibonelo esijwayelekile ukukhubazeka kwama-fuse noma amanethiwekhi ahlanganisiwe ane-LED kanye nezibani ezijwayelekile zokukhipha ezine-ballast ejwayelekile, enikezela ngama-volts ayizinkulungwane eziningana zamandla okushisa.

Izinkokhelo ze-Electrostatic ziyinto eyenzeka ikakhulukazi esimweni seL Protectionina II Luminaires lapho ukwahlukaniswa kwemali kwenzeka khona bese kuba namandla aphezulu ezindlini ezikhanyayo noma echibini lokushisa le-LED. Lesi simo siyinselelo yangempela kubo bonke abashayeli bezimoto. ngubani, lapho ebamba imoto yakhe, kwesinye isikhathi angathola ukushaqeka kukagesi.

Ikakhulukazi okuthintekayo yizinkanyiso eziqhutshwa zihlukaniswe ngokuphelele namandla omhlaba.

Amaphutha amapayipi angaholela kulokho okubizwa ngama-overvoltages wesikhashana. Ukwehla komqhubi ongathathi hlangothi, isb ngenxa yomonakalo, kuyimbangela ejwayelekile kakhulu lapha. Ngaleli phutha, amandla we-voltage angakhuphuka aze afike ku-400 V ezigabeni ngenxa yama-asymmetries ama-mains kwizigaba ezintathu zamapayipi. Ukuvikelwa kokuqhuma kwesikhashana kudinga ukucatshangelwa okukhethekile.

Kodwa kukhona nezinkinga ekwakheni nasekubakhanyiseni amahholo. Ikakhulu lapho ama-overvoltages angaveli ngaphandle, kepha nsuku zonke avela esitshalweni sakho. Ikakhulu, amacala aziwa embonini, lapho kukhiqiza khona ama-overvoltages ezintweni zikagesi futhi okubangelwa wiring kagesi kufinyelela ekukhanyeni. Ukwehluleka kokuqala ngezikhathi ezithile ama-luminaires noma ama-LED ayizimpawu ezijwayelekile zalokhu.

Ngokuya ngalokhu okuhlangenwe nakho, futhi, abakhiqizi be-luminaire bahlangabezane nezidingo zabo emandleni e-luminaires ngokumelene nama-overvoltages. Kula amandla ezikhanyiso zomgwaqo ngokulwa nama-overvoltages eminyakeni eminingana edlule. ku-approx. 2,000 - 4,000 V, njengamanje imaphakathi cishe. 4,000 - 6,000 V.

Lokhu okuhlangenwe nakho kubangele nabakhiqizi be-luminaire ukuthi baphakamise izidingo zabo zamandla we-luminaire uma kuqhathaniswa nemikhawulo yokwenyuka. Ngenkathi eminyakeni embalwa edlule amandla ezibane zasemgwaqeni ngokulwa nokuqubuka kwamavolthi ayesondele. 2,000 - 4,000 V, okwamanje isondele. 4,000 - 6,000 V ngokwesilinganiso.

Ukuze ucabangele lokhu, abakhiqizi abaningi be-luminaire banikela ngenketho yamaLuminaires anedivayisi enamandla yokuvikela (Type SPD) yohlobo lwe-2 + 3 (SPD) ukuvikela umhlaba. Uma lokhu kungenzeki noma kungamabomu, isb ngenxa yokushoda kwesikhala noma ngenxa yokuthi amalambu asevele efakiwe enkundleni, i-SPD nayo ingafakwa ebhokisini le-fuse mast. ingasetshenziswa. Lokhu kunikeza nokusizakala kokulungiswa okulula nokufakwa kabusha. Ukuqedela umqondo wokuvikela nokukhulula amaphuzu wokukhanya. Kufanele futhi ifakwe uhlobo oluhlanganisiwe lokubamba olungu-1 + 2 kumshintshi wasemgwaqeni / osabalalisayo ophakathi nokusatshalaliswa kwemisinga yombani kanye namavolontiya avikelwe.

Kubunjiniyela bezinsizakalo zokwakha, ukuvikelwa okusebenzayo kungatholakala ngokuhlomisa ukufakwa kagesi ngamadivayisi wokuvikela umbani kanye nokuqhuma. Isibonelo, imibani ehlanganisiwe kanye ne-surge arresters yohlobo 1 + 2 ingasetshenziselwa ukuvikela imisinga yombani kanye nezikhathi zamapayipi ekwakheni amasistimu okuphakelayo, kanye namabhokisi okusabalalisa ukukhanya we-SPD 2 + 3 namabhokisi okuhlangana ezikhanyiso angasetshenziswa ukuvikela ukuhlangana kwensimu nokuguqula ama-overvoltages.

Ukuvikelwa kokusebenzisa ngokweqile kwemoto

Kunabakhiqizi abaningi bokuvikelwa kokuqhamuka emakethe. Ngakho-ke kufanele kususelwe kulawa maphuzu alandelayo lapho ukhetha amadivayisi wokuvikela ukuqhuma kufanele anakwe kakhulu.

Ukuvikelwa okuhle kwe-overvoltage kufanele kuhlolwe ngokwe-IEC 61643-11 kanye nezidingo ze-VDE 0100-534. Ukuze kuzuzwe lokhu, izidingo ezilandelayo ziphakathi kokunye ukuhlangabezana nesimo sokukhombisa isimo futhi amadivayisi okunqamula ahlanganisiwe ku-SPD.

Njengoba i-SPD ivame ukufihlwa ezindaweni ezingafinyeleleki, isb kuma-luminaires afakiwe, ukusayinwa kwe-optical okumsulwa akulungile. I-SPD engakwazi futhi ukunqamula ukukhanya kumjikelezo uma kwenzeka kuba nephutha, lezi zici ezilandelayo ziyatholakala lapha indlela enhle nelula yokubonisa ngokungaqondile.

Ubuchwepheshe be-LED buya ngokuya bubaluleka ekukhanyeni. Ubuchwepheshe obuthuthukisayo buqinisekisa izixazululo ezinokwethenjelwa nakakhulu. Izindlela zokubopha ze-Overvoltage ezibheke ukuzijwayeza, nezimo zokuvikela zifaka i-elekthronikhi ebucayi emanothweni angaba yingozi. Izindleko ezingeziwe zomqondo osebenza kahle wokuvikelwa kwamandla kagesi wohlelo lwe-luminaire okwamanje zibala ngaphansi kwephesenti elilodwa lezindleko eziphelele. Izindlela zokuvikelwa kwamandla okusebenzisa ngokweqile ngakho-ke ziyadingeka kubo bonke abasebenzisi bezitshalo. izindlela ezilula futhi ezimeni eziningi ezibaluleke kakhulu zokuqinisekisa impilo yenkonzo ende nokwethembeka kokukhanyisa nokugwema izindleko ezilandelanayo.

Imiqondo yokuvikelwa yokwanda yezinhlelo ze-LED zokukhanyisa emgwaqweni

Ubuchwepheshe be-LED obuhlala isikhathi eside busho imisebenzi engaphansi yesondlo nezindleko eziphansi

Amalambu emigwaqo njengamanje akhishwa kabusha yimiphakathi eminingi nezinsiza zikamasipala. Ama-luminaires ajwayelekile abuyiselwa ama-LED ngokuyinhloko. Kungani lokhu kuguqulwa kwenzeka manje? Kunezizathu eziningi: izinhlelo zezimali, ukusebenza kahle kwamandla, ukuvinjelwa kubuchwepheshe obuthile bokukhanyisa futhi, nakanjani, ukugcinwa okuphansi kwezikhanyiso ze-LED.

Ukuvikelwa okungcono kobuchwepheshe obubizayo

Ubuchwepheshe be-LED bunezinzuzo eziningi. Kodwa-ke, futhi inegciwane lesandulela ngculazi elisezingeni eliphansi kunobuchwepheshe obujwayelekile be-luminaire. Ngaphezu kwalokho, izibani ze-LED zibiza kakhulu ukuzisusa. Ngokwenzayo, ukuhlaziywa komonakalo kuveze ukuthi ama-surges ajwayele ukulimaza ngaphezu kwelilodwa lomgwaqo we-LED ngasikhathi.

• Vimbela ukwehluleka
• Faka phakathi i-Surge Protection

Ukulimala okujwayelekile okuvela kuma-surges kungaba ukwehluleka okuyingxenye noma okuphelele kwemodyuli ye-LED, ukubhujiswa komshayeli we-LED, ukulahleka kokukhanya noma ukwehluleka kwayo yonke i-electronics control.

Noma isibani se-LED siqhubeka nokusebenza, ama-surges ngokuvamile anomthelela omubi empilweni yenkonzo yawo.

Gwema imisebenzi yesondlo engadingekile nokuvikela ukutholakala ngomqondo osebenzayo wokuvikela ukukhuphuka.

I-SLP20GI yisiboshwa esifanelekile kuwe - ungafaka inguqulo ye-IP65 ngaphandle kwaso.

Mane nje uthintane nathi. Sizojabula ukukusiza ekuhleleni kwakho.

Ukuvikelwa kokukhanya kokukhanya kwangaphakathi kwe-LED

Ababambi abanamandla bokuvikela bavikela ubuchwepheshe obuzwelayo be-LED. Zivimbela ukulimala futhi ziqinisekisa isikhathi eside sokukhanya kwe-LED.

Njengo-opharetha, wehlisa izindleko zokufaka okunye futhi wonge emsebenzini wokulungisa obizayo futhi odla isikhathi.

Enye inzuzo: ukutholakala unomphela kokukhanyisa kusho ukusebenza nezinqubo zokukhiqiza ezingaphazamiseki kanye nabasebenzisi abanelisekile.

Umqondo wokuvikela ukukhanya kwe-LED yasendlini
Ngomqondo ophelele wokuvikela, cabanga ngezindawo zokufaka ezilandelayo:
A - ngqo ekukhanyeni kwe-LED / emgqeni wokukhanya
B - ohlelweni lokusabalalisa olungaphansi olukhuphukayo

Leli thebula likhombisa amazinga ancishisiwe omzimba wokuzivikela we-C136.2-2015 wezinhlelo zokusebenza ezivamile zokukhanyisa ngaphandle:

Ithebula 4 - 1.2 / 50µs - 8 / 20µs Incazelo yokuhlolwa kwegagasi lenhlanganisela
