Ungayikhetha kanjani umakhi we-SPD wedivayisi yokuvikela
Amaphuzu ayi-8 abalulekile wokuthenga okokuvikela okungaxhuma okuvela eChina
Thina be-LSP abakhiqizi baseChina kusukela ngo-2010, sigxila emizamweni yethu ekuthuthukiseni ukuvikelwa kokukhiqizwa nasekukhiqizweni kwamadivayisi wokuvikela we-AC DC PV, silwela ukukhonza amakhasimende ethu ngemikhiqizo esezingeni eliphakeme.
Uma ungumngenisi wezinto ezisebenza ngogesi, umenzeli, umhambisi, umthengisi noma umthengisi, lapho uthenga i-AC ne-DC noma i-PV SPDs (amadivayisi wokuvikela), kufanele wazi amaphuzu ayisishiyagalombili abalulekile okuthenga idivaysi yokuvikela (i-SPD) evuselelekayo engashintsheka evela eChina
1. Izinto eziwumbala
(1.1) I-Metal oxide Varistor - MOV
Njengengxenye eyinhloko yama-SPD angaphakathi, ngokungadingekile ukusho, ikhwalithi ye-SPD incike kakhulu kukhwalithi ye-varistors. Ngokusobala sebenzisa ikhwalithi ye-MOV ebaluleke kakhulu, kunezinhlamvu eziningi ezidumile ze-brand metal oxide varistors yokukhetha njenge-EPCOS / TDK, Littelfuse, Keko, Varsi…
Umkhiqizo odumile emhlabeni

Ngemuva kokukhetha uphawu lwe-varistor (MOV), wazi kanjani ukuthi ukhethe i-voltage eyi-MOV efanele? Ungakhathazeki, ake sikuqondise ukuthi ukhethe i-varistor efanele.
Ake sibone imingcele yezobuchwepheshe ye-MOV okokuqala, uhlu njengoba lungezansi.

Uma ufuna uku-oda i-SLP40-275 / 4 (UC = 275Vac, IMAX = 40kA), sicela ubheke itafula (sikuphawula libomvu), ikholomu UMax. voltage eqhubekayo yokusebenza (UC) - i-VRMS (V), thola idatha engu-275V, Sizothola imodeli I-CJA34S-431.
PS
I-CJ: isho uhlobo lweCJ.
A: kusho i-AC
34S: kusho isikwele esingu-34mm
431: kusho ukuthi i-varistor voltage ingu-430V
Ngemuva kokukhetha i-metal oxide varistor (MOV), kusadingeka ukuthi sinake ukuthi siyibeka kanjani ezindlini ze-SPD. kunezindlela ezimbili:
A. ukwahlukanisa camera varistor, ngokuvamile camera ngombala oluhlaza noma oluhlaza okwesibhakabhaka umswakama-ubufakazi.
B. Abanye abakhiqizi be-SPD basebenzisa i-varistor enqunu ne-contactor, idinga ukusebenzisa i-epoxy resin ukushumeka Udinga ukwazi ukuthi i-epoxy resin ayisebenzisi imvelo, umkhiqizo odumile wama-SPD awusakwenzi lokho futhi.
C.Ukunciphisa izindleko, abanye abakhiqizi be-SPD basebenzisa i-varistor encane ukufaka i-varistor engama-34S, ake sithathe isibonelo, uma ufuna ukuthenga ama-SPD wekhwalithi, ngethemba ukuthi ukukhishwa kwe-Nominal yamanje (8 / 20μs) Ku = 20kA kanye ne-Maximum discharge current / 8μs) Imax = 20kA, kufanele isebenzise i-40S varistor (34 isho ukuthi 34mm; “S” isho isikwele), kepha basebenzisa i-varistor encane efana ne-34D, 20D, 25D ukufaka ama-32S. Bhala kuhlu idatha ye-varistors yezobuchwepheshe njengoba ingezansi:

(1.3) Idizayini yesakhiwo sangaphakathi
Ama-SPD amaningi kakhulu emakethe, uzobona ukuthi kunesakhiwo sezitayela ezimbili zangaphakathi ngaphakathi kwe-modular pluggable: isitayela seDehn nesitayela se-OBO
Isitayela se-OBO:
lapho kuza ukuqhuma okukhulu kwamanje, ububanzi bengxenye yokuxhuma kwensimbi bumncane kakhulu, abukwazi ukumelana namandla wamanje angama-40kA.
Isitayela se-Dehn:
Ngenxa yokwakheka okufanele, ingamelana nomswakama wokuqhuma we-Imax = 40kA.
(1.4) Izindlu zepulasitiki
okokusebenza kwekhwalithi yi-PA66 noma inayiloni yokuvikela umlilo.
(1.5) Izingxenye zensimbi, okubalulekile kwensimbi kufanele kube yimbumba yensimbi, hhayi insimbi.
Isitayela se-OBO sisebenzisa izingxenye zensimbi zensimbi:
Isitayela sikaDehn sisebenzisa izingxenye zensimbi ze-cooper:
(1.6) Izinto ezivikela imvelo
Enye imboni isebenzisa i-epoxy resin ukuvala uphawu. I-epoxy resin inephunga futhi ayikulungele ukuvikelwa kwemvelo nempilo.
Sisebenzisa i-varistor ehlanganisiwe, ayidingi i-epoxy resin, kungcono ekuvikelweni kwemvelo.
2. Ukuzenzekelayo kokukhiqiza
Izingxenye zensimbi zixhuma ne-MOV (varistor) kufanele zishiselwe ngokuthembekile. uma i-welding yesandla, kwenzeka kalula i-solder enganele. Ngakho-ke ukushisela okuzenzakalelayo kungagcina ukuhambisana kwekhwalithi yomkhiqizo. https://www.youtube.com/watch?v=RHwNJv8hobE
3.Laboratory and testing
Njengomkhiqizi we-SPDs, kufanele abe nesethi yokuhlola yokusetha yonke into yokuhlola umkhiqizo ukuthi ngabe ukuhambisana ku:
| AmaZinga | izinto | Ukuhlukaniswa kokuhlolwa / Isigaba Sokuhlola |

Sinohlu lwama-equipments wokuhlola njengoba kungezansi:
(1) I-generator yokwenyuka (Imax efinyelela ku-150kA [8 / 20μs]; Iimp kufika ku-25kA [10 / 350μs])
(2) Inhlanganisela ye-waveform 1.2 / 50μs voltage impulse & generator yamanje (Uoc: 6kV [1.2 / 50μs]; Imax 4kA [8 / 20μs])
(3) Umhloli wokuqina wokushisa
4. Ukuphathwa kweworkshop
I-5. Isitifiketi:

I-IEC 61643-11: 2011 / EN 61643-11: 2012 Izinga Lomhlaba Wonke - Ngabe amadivayisi akho Wokuvikela (SPDs) ahlolwe futhi athobela?
Amadivayisi Wokuvikela Kufanele Ahlangabezane Namazinga
IEC 61643-11: 2011 / EN 61643-11: 2012 Amadivayisi wokuvikela amandla amancane - Ingxenye 11 Amadivayisi wokuvikela amadivayisi axhunywe kumasistimu amandla kagesi anamandla aphansi - Izidingo nezindlela zokuhlola
Amadivayisi wokuvikela (ama-SPD) kumele ahlinzeke ngemisebenzi yokuvikela echaziwe kanye nemingcele yokusebenza ukuze ikwazi ukusebenziseka emiqondweni yokuvikela ehambisanayo. Ngakho-ke, ziyakhiwa, zivivinywe, futhi zihlukaniswe ngokochungechunge lwazo lwamazwe omhlaba lwamazinga womkhiqizo.
Amadivayisi wokuvikela axhumeke kumasistimu wamandla we-low-voltage ancike kuzidingo nezindlela zokuhlola ezichazwe yi-IEC 61643-11: 2011 / EN 61643-11: 2012 International Standard ejwayelekile.
Uphawu lwangempela lwekhwalithi isitifiketi somkhiqizo nokuvunywa okuvela esikhungweni sokuhlola esizimele. Lokhu kuqinisekisa ukugcwaliseka kwezinga lomkhiqizo wakamuva nje ukuqinisekisa ukuphepha okuphezulu nobuqotho bama-SPD. Izidingo zokulawulwa ezibekwe kuma-SPDs zivame ukuthi zidinge izivivinyo eziyinkimbinkimbi kakhulu ukuthi zingama-laboratories wokuhlola ambalwa kuphela emhlabeni akwazi ngokuphelele ukuwenza.
Wazi kanjani?
Ikhwalithi nokusebenza kwamadivayisi wokuvikela ukuqhuma kunzima kumakhasimende ukuwahlola. Ukusebenza okulungile kungahlolwa kuphela kumalabhorethri afanele. Ngaphandle kokubukeka kwangaphandle nama-haptics, kuphela imininingwane yezobuchwepheshe enikezwe umenzi enganikeza noma yisiphi isiqondiso. Okubaluleke kakhulu isitatimende esithembekile esivela kumenzi & ukunikwa isitifiketi / ukuvunywa maqondana nokusebenza kwe-SPD nokwenza izivivinyo ezichazwe kumazinga afanele omkhiqizo kusuka ochungechungeni IEC 61643-11: 2011 / EN 61643-11: 2012
Faka kuhlu isitifiketi esihambisana namazinga

6.Isikhathi sokubhalisa sefektri nolayini womkhiqizo omkhulu.
(6.1) Uma kufanele ihlole ilayisense lebhizinisi lomkhiqizi, ukugxila isikhathi eside ekukhanyeni nasekuvikeleni inkambu, kusho ukuthi ifektri ingongoti kakhulu.
(6.2) Umugqa womkhiqizo oyinhloko. umphakeli ochwepheshe kufanele agxile enkambeni yokuvikela umbani kanye nokwanda. Ulayini womkhiqizo ungafaka:
A. Uhlelo lokuphakelwa kukagesi lwe-AC ne-DC luqhuma amadivayisi wokuvikela
B. Idatha / umugqa wesiginali wokuvikela umvikeli
C. Amadivayisi we-RF coaxial surge protection
D. I-Lighting Rod, isibali somcimbi wombani, induku yomhlaba, umqhubi wezansi njll.
I-7. Isiqinisekiso Somkhiqizo
Umkhiqizo odumile njengo-Dehn, i-OBO, banikeza iwaranti yeminyaka emi-5. uma umkhiqizi eqinisekisa ukuthi banikezela ngomkhiqizo wekhwalithi, kufanele unikeze iwaranti yeminyaka engu-3-5.
I-8. Iphakheji
Noma ngabe iluphi uhlobo lwefekthri noma i-OEM, umkhiqizi kufanele ahlinzeke ngesitembu esifanele (i-serigraphy), iphakethe (ibhokisi nebhokisi), iphepha noma ibhukwana le-elektroniki (imiyalo yokufaka)
Ungayikhetha kanjani umakhi wedivayisi yokuvikela i-SPD, Lawa maphuzu abalulekile ayi-8 wokuthenga okokuvikela okungaxhuma kusuka eChina, ngethemba ukuthi kuyasiza.
Siyinkampani yomndeni futhi besinikezela ngamadivayisi wokuvikela ukuqhuma (i-SPD) emhlabeni wonke isikhathi esingaphezu kweminyaka eyi-10. Sineyethu ucwaningo nentuthuko, ukukhiqiza, ukwesekwa kwezobuchwepheshe kanye nelabhorathri yokuhlola.
I-LSP akhiqizwa hhayi kuphela okwakhiwa kwezindawo zokuhlala nezingezona zokuhlala, kodwa futhi nokusetshenziswa kwezimboni njengamapayipi kawoyela, amapayipi kagesi, ama-photovoltaics, iziteshi zamandla nojantshi. Imikhiqizo yethu ivikela ekukhuphukeni kobuchwepheshe obuhlukahlukene, imishini, izinto ezisetshenziswayo nemishini emhlabeni wonke.
Siphinde sithuthukise futhi sakhe amadivayisi wokuqapha ukwahlukanisa (i-IMD) wamanethiwekhi we-IT wokuphakelwa kwamandla angawodwa. Sinikezela ngesixazululo esibanzi, esiyinkimbinkimbi se-A to Z sokuqapha isimo sokufakwa ezibhedlela, embonini nasezinsizeni ezikhethekile.
Asizenzi ngathi singenza konke, Uma unemibuzo neziphakamiso mayelana nezinto ze-SPDs, iqembu lethu labachwepheshe abanamakhono lizojabula ukuphendula imibuzo yakho futhi likutholele umkhiqizo ofanele.
