Amadivayisi wokuvikelwa kwezicelo zezimboni

Izicelo zezimboni zifaka izinhlobo ezahlukahlukene zemishini edinga ukuvikelwa emiphumeleni yama-surges. Ziyabiza kumnikazi wenkampani: intengo ingaba nkulu kakhulu futhi ukwehluleka, noma ukushintshwa, kwalawo madivayisi, kungahle kube nokulahlekelwa okukhulu kwezezimali, okungenzeka kubeke ukuba khona kwale nkampani engcupheni. Izici ezibalulekile, ngokombono wezinyunyana, abasebenzi: basebenzisa imishini kagesi futhi, uma kwenzeka kuqhuma, izimpilo zabo zingaba sengozini. Amaqiniso ashiwo ngenhla, kanye nezinye izimbangela, amelela izizathu ezinqala zokuthi kungani umuntu kufanele afune ukuvikelwa kuma-surges. Lo msebenzi usebenzisa ukuvikelwa kwangaphakathi nangaphandle emibani, njengamatheminali womoya, isisekelo, ibhasi evikelayo, abacindezeli bezingcindezi, konke ngokuhlanganyela okubizwa ngokuthi yimishini yokuvikela ukuqhuma, i-SPD. Kunezinkampani eziningi ezikhiqiza inqwaba yamadivayisi, kepha akuzona zonke ezifanele izicelo zezimboni.

Inhliziyo yakho konke, njengoba kunjalo ngokujwayelekile, ilele kusiqondisi noma imfuneko yezomthetho. Kulesi simo esithile, kungukuvikela okujwayelekile kwe-EN 62305, Izingxenye I kuya ku-4. Umbhalo uphinde uchaze izinhlobo zomuntu ngamunye zokulahleka, ubungozi, izinhlelo zokuvikela umbani kanye nezinga lokuvikelwa kombani. Kunamazinga amane wokuvikelwa kombani (I kuya ku-IV) acacisa imingcele yombani; amazinga okuvikelwa angumsebenzi wezinga lobungozi. Kuzicelo eziningi zezimboni, lesi sakhiwo sihlukaniswa njengeleveli I noma II. Lokhu kufana namanani aphezulu wombani wamanje I_imp (umfutho wamanje ngamapharamitha 10/350 beings) uphakama njengama-200 kA. Ukulinganisa okufanelekile kusikisela ukuthi ama-50% we-I jikelele_imp I-current iboshwa ngamatheminali omoya bese ihanjiswa ohlelweni lokumisa phansi. Ama-50% asele asatshalaliswa ngokulinganayo kokufakwayo (isb. Phakathi koxhumana nabo bangaphandle abangena esakhiweni), ikakhulukazi ezintanjeni ze-IT nezokuxhumana, amapayipi wensimbi namakhebuli kagesi we-LV.

Ezimweni ezimbi kakhulu, i-SPD idinga ukubopha okungenani i-100 kA. Lapho kusatshalaliswa imicu ngayinye, amanani amanje afinyelela kuma-25 kA ngomucu ngamunye (kusetshenziswa uhlelo lwe-TN-C). Kungakho sincoma ukuthi abasabalalisi abakhulu beziteshi ze-LV (ezakhiweni ezifanelekela ukuba yizinga lokuvikela i-LPL I) bafakelwe I-FLP50GR kuvalwe igebe le-spark ngokugcwaliswa kwegesi. Ukuba wuhlobo lwe-SPD 1, imishini iqinisekisa ukulingana kokulahlwa kwamandla ombane kanye nokuqhutshwa kokushintsha okwenziwa kulayini bokuhambisa amandla abangena esakhiweni.

Iyakwazi ukubopha mina_imp imisinga enkulu njengama-50 kA. Izakhi zezingxenye zamabhilidi ngazinye kufanele zifakwe I-FLP25GR, inhlanganisela yohlobo lwe-SPD 1 no-2, efaka ama-varistor amabili okuphepha okuphezulu futhi anikezela ngama-25 kA wamanje we-impulse current impulse. Ama-substation wesibili namakhabethe wokulawula kufanele afakelwe uhlobo lwe-SPD 2. Isibonelo salelo banga ebangeni lethu lomkhiqizo yi I-SLP40, enikelwa njengeyunithi ephelele, evaliwe noma enamamojula angashintshwa.

Uma ngabe idivayisi evikelwe itholakala kumamitha ayi-5 ukusuka kwesitishi esingaphansi kwesibili noma ikhabethe lokulawula, uhlelo kufanele luhlonyiswe ngokwengeziwe ngeyunithi ye-SPD Type 3, ngokwesibonelo, i-TLP10. Kuyisihlungi semvamisa ephezulu esine-attenuation min. I-30 dB ku-frequency band 0.15 - 30 MHz efaka nezinsimbi zokuvikela - ama-varistor akhiqizelwa imisinga ekaliwe kusuka ku-16 kuye ku-400 A. Kuleso simo, isithintelo sokuhlukanisa umfutho i-LC63 sidinga ukufakwa phakathi kohlobo lwe-SPD 2 no-3 ukuhlinzeka ngokuxhumana okulungile kwababoshiwe. Izintambo ezivikelekile zidinga ukuhlinzekwa phakathi kwesiteshi kanye nemishini evikelwe ukuze isebenze kahle.

I-LSP futhi inikeza ukuvikelwa kwezimo lapho uphahla lwesakhiwo luthwala amaphaneli we-photovoltaic. Isincomo sethu yi I-SLP40-PV uchungechunge olukhuphuka ngaphambi kwe-inverter nengaphakathi lalo kufakwe ama-disconnectors asatshalaliswa uma kwenzeka ukwehluleka (ukushisa ngokweqile) kwama-varistor kanye nokuma komshini, okufakwa phakathi kwama-electrode anqanyuliwe ukulungiselela izimo ezifanele zokubulala i-DC arc. Ukuvikelwa kokuqubuka kokushintshana kwamanje kuyadingeka, ukhetho oluhle kakhulu yi- Uchungechunge lwe-FLP7-PV.

Sincoma ukuthi abafaka lolu hlobo bafakwe emakamelweni afana namahholo ama-server, amagumbi okulawula, kanye namahhovisi. I-Tele-Defender-RJ11-TELE yokuvikela imishini yokuxhumana ngocingo, iNet-Defender-RJ45-E100 yokuvikela ukudluliswa kwedatha namasiginali olwazi, I-COAX-BNC-FM ukuvikelwa kwemishini eqhuba isignali yevidiyo edlulisiwe, INet-Defender-ND-CAT-6AEA enzelwe ukuxhumana kwamakhompiyutha ngaphambi kokufaka ikhadi lenethiwekhi futhi enzelwe ukuvikela nokudluliswa kwedatha kumanethiwekhi weGeneration 5, futhi I-RJ45S-E100-24U ukufakwa kwabasabalalisi abangu-19-intshi kuseva ukuvikela ukudluliswa kwedatha kumanethiwekhi ekhompyutha: idivayisi inikela ngamasokhethi e-RJ45 kanye nezixhumi ze-LSA-PLUS. Ukuvikelwa kwedatha nolayini bezokuxhumana kanye nezinsimbi ze-I & C nezilawuli zomugqa wokukhiqiza, imishini, nemishini ebalulekile, sincoma ukuthi kusetshenziswe Uchungechunge lwe-FLD2 eziletha ukuvikelwa ngababambi bombani kanye nama-diode we-voltage-suppression. Banikezwa ngemiklamo ehlukahlukene ngenombolo ekhethiwe yamabhangqa kanye namandla kagesi alinganisiwe ochungechungeni olunikeziwe. Ukuxhumana ne-interface ye-serial RS 485, sinikeza ukuvikelwa kwaleyo migqa sisebenzisa uchungechunge lwe-FLD2 oluvikela okokusebenza okuxhunywe ekuqhamukeni okuguqukayo nobude obude. Ukuvikelwa kwamakhamera nama-aggregator esignali yevidiyo, ikakhulukazi ezinhlelweni zokuphepha ngogesi kanye nezinhlelo zokuvikela umlilo i-EPS isebenzisa i-FLPD2 enezinto ezingezona ezomugqa zamaza e-Imax aze afike ku-6.5 kA. Ukuvikelwa kwamadivayisi axhunywe ohlelweni lwe-antenna ngekhebula le-coaxial kufanele kufakwe izivikeli zokwanda. I-LSP inikela ngezinhlobonhlobo zezivikeli ze-coaxial zezinhlobo ezahlukahlukene zezixhumi nezigaba ezithile zokusebenza ezingasetshenziswa ezinhlotsheni eziningi zezinhlelo zokusebenza. Le SPD iqukethe iziboshwa ezikhethekile zombani ezinesilinganiso esiphezulu sokukhishwa kwe-Imax (8/20 µs) = 10 kA ukuhlinzeka ngokuvikelwa okuthembekile kwezinhlelo zokwamukela nokusakaza emiphumeleni yesiteleka sombani ezindaweni eziseduze. Banikela ngokuncishiswa okuphezulu kokuphola okungaphansi kwama-20 dB.

Isihloko sokuvikelwa kuma-surges akuyona into elula; ukwakheka okufanele kuncike ezintweni eziningi ezinikelayo. Sikumema ukuba uthintane nabamele abathengisi bethu abafanelekile abazojabula ukukucebisa ekukhetheni uhlobo olufanele lokuvikelwa kokuhlinzeka ngokuvikela impahla yakho nokunciphisa ukulahleka nokonakaliswa kwempahla yakho.

Izidingo zokusetshenziswa kwamadivayisi wokuvikela ama-Surge (SPDs) kuma-Panels Control Panels

Amadivayisi Wokuvikela (i-SPDs) asetshenziswa kakhulu kumapaneli wokulawula izimboni. Ithebula elingezansi li-itemization yezinhlobo ze-SPD nokuthi zingasetshenziswa kanjani kumapaneli lapho kungekho ncazelo yeNqubo edingekayo. Izidingo zezilinganiso ze-Voltage ne-Nominal Discharge Current (NDC) ze-SPD zikhonjisiwe kuthebula elingezansi. Ama-SPD asetshenziswa ngaphandle kwemihlahlandlela yaleli thebula adinga incazelo yeNqubo. Ngokuya ngokuhlolwa kwe-SPD, le mihlahlandlela ingeqiwa uma kwenziwa ukuhlolwa kobunjiniyela.

Ithebula lisebenza kuma- “One-Port” SPDs, okuvame kakhulu. Lapho kusetshenziswa i- “Two-Port” SPD, kuzoba uhlobo oluvunyelwe etafuleni elingenhla, ngokuya ngokusetshenziswa kwephaneli, futhi lisetshenziswe ngaphakathi kwezilinganiso zalo ezimakiwe, kufaka phakathi i-Short Circuit Current Rating (SCCR). Lapho ama-SPD wohlobo lwamachweba amabili engamakiwe nge-SCCR, kucatshangwa ukuthi yi-3A. Uma ngabe i-Two-Port device yaziwa ngeNothi 1000 ekhasini lohlu lohlu (okukhombisa ukuthi ukuvikelwa okuthe xaxa kwangaphandle kuyadingeka), le SPD idinga inqubo echazwe.

• I-R / C ichaza into eyaziwayo

1, Kufaka phakathi amaphaneli abhalwe ukuthi “Ifanele Ukusetshenziswa Njengezinsiza kusebenza”

2, Isilinganiso samandla we-SPD sizoba okungenani esikagesi wesigaba esigcwele (LL) wamandla kuzo zonke izindlela (okungukuthi i-LN, LL, LG). Isibonelo, amapaneli alinganiswe u-277 / 480V azosebenzisa i-SPD elinganiselwe ngo-480V kuzo zonke izindlela; amaphaneli akalwe ngo-120 noma ngo-120/240 azosebenzisa i-SPD elinganiswe ngo-240V kuzo zonke izindlela.

Isigama se-SPD:

I-Port eyodwa - i-SPD ingaphesheya komugqa.

IPort ezimbili - i-SPD ingaphesheya komugqa, kanye nokujikeleza okwengeziwe ochungechungeni nomthwalo. Ukugeleza kwamanje ngale divayisi ngeke kudlule isilinganiso saso samanje esimakiwe.

Amanothi - Ukucaciswa kwezidingo:

• Lapho kuchazwe khona iVoltage, amanani we-MCOV (Maximum Continuous Operating Voltage) angahle abe
• I-Nominal Discharge Current (NDC): Kungabuye kubhekiswe naku-IN. Izilinganiso ezijwayelekile zingama-3kA, 5kA, 10kA, noma ama-20kA.Izincazelo - kusuka ku-UL1449 (kuyafundisa)

Thayipha Izilinganiso (kusebenza kwizitifiketi ngaphambi kuka-Ephreli 2010):

Thayipha i-1 - Ama-SPD axhunywe unomphela enzelwe ukufakwa phakathi kwesekeli se-transformer yesevisi nohlangothi lwensimbi yedivayisi yokusebenza kwensimbi, kanye nohlangothi lokulayisha, kufaka phakathi ukuvalwa kwesokhethi lemitha le-watt futhi kuhloswe ukufakwa ngaphandle kwe-overcurrent yangaphandle into evikelayo.

Lawa madivayisi afakwe kuhlu.

Thayipha i-2 - Ama-SPD axhunywe unomphela enzelwe ukufakwa ohlangothini lomthwalo wedivayisi yokusebenza kwensimbi eyeqile; kufaka phakathi ama-SPD atholakala kuphaneli yegatsha.

Lawa madivayisi afakwe kuhlu.

Thayipha i-3 - Indawo yokusebenzisa i-SPDs, efakwe ebangeni eliphansi lomqhubi wamamitha ayi-10 (30 feet) ukusuka kuphaneli yesevisi kagesi kuze kube seqophelweni lokusetshenziswa, ngokwesibonelo, intambo exhunywe, i-plug-in eqondile, uhlobo lwe-receptacle kanye nama-SPD afakwe ku imishini yokusebenzisa iyavikelwa. Bona ukumakwa ku-64.2. Ibanga (amamitha ayi-10) likhethekile kubaqhubi abanikezwe noma abasetshenziselwa ukunamathisela ama-SPD.

Lawa madivayisi afakwe kuhlu.

Thayipha ama-4 Component SPDs, kufaka phakathi izinto ezi-discrete kanye nemihlangano yento.

Lawa madivayisi abonwa njengo “Thayipha 4 ukuze usetshenziswe kuzinhlelo zokusebenza ze-xxx” lapho i-xxx ingaba ngu-1, 2, 3, noma “enye”. Izilinganiso zohlobo (kusebenza kwizitifiketi ngemuva kuka-Ephreli 2010):

Thayipha i-1 - Ama-SPD axhunywe unomphela enzelwe ukufakwa phakathi kwesekeli se-transformer yesevisi nohlangothi lwensimbi yedivayisi yokusebenza kwensimbi, kanye nohlangothi lokulayisha, kufaka phakathi ukuvalwa kwesokhethi lemitha le-watt futhi kuhloswe ukufakwa ngaphandle kwe-overcurrent yangaphandle into evikelayo.

Lawa madivayisi afakwe kuhlu.

Thayipha i-2 - Ama-SPD axhunywe unomphela enzelwe ukufakwa ohlangothini lomthwalo wedivayisi yokusebenza kwensimbi eyeqile; kufaka phakathi ama-SPD atholakala kuphaneli yegatsha.

Lawa madivayisi afakwe kuhlu.

Thayipha i-3 - Indawo yokusebenzisa i-SPDs, efakwe ebangeni eliphansi lomqhubi wamamitha ayi-10 (30 feet) ukusuka kuphaneli yesevisi kagesi kuze kube seqophelweni lokusetshenziswa, ngokwesibonelo, intambo exhunywe, i-plug-in eqondile, uhlobo lwe-receptacle kanye nama-SPD afakwe ku imishini yokusebenzisa iyavikelwa.

Lawa madivayisi afakwe kuhlu.

Thayipha 1, 2, 3 Component Assemblies - Iqukethe umhlangano wezinto zohlobo lwe-4 onokuvikelwa kwesifunda okufushane kwangaphakathi noma kwangaphandle.

Le yimibuthano efana ne- “Open Type Devices” ye-UL508. Zingaba isitimela se-DIN esifakelwe ukufakwa kwephaneli. Izinhlobo zemihlangano yohlobo 1 no-2 ihlolwe okwesikhashana.

Thayipha i-4 Component Assemblies - Umhlangano we-Component oqukethe into eyodwa noma eziningi zohlobo lwe-5 ndawonye nokunqamula (okuhlanganisiwe noma kwangaphandle) noma indlela yokuthobela izivivinyo ezilinganiselwe zamanje kusigaba 1449 (edition 44.4) se-UL4. Lawa madivayisi ayaziwa, ngokuvamile ahlukanisiwe anohlobo oluthile lokuvikelwa okushisayo. Kungenzeka bahlolwe isifunda esifushane noma kungenzeka.

Thayipha u-5 - Izicindezeli zokuxhuma izinto ezi-discrete, ezinjengama-MOV angabekwa kwi-PWB, exhunywe ngemikhombandlela yayo noma enikezwe ngaphakathi kwendawo ebiyelwe enezindlela ezengeziwe zokunqamula izintambo.

Lawa madivayisi ayaziwa, ngokujwayelekile ahlukanisiwe ngaphandle kokuvikelwa okushisayo.
