Idivayisi yokuvikela ukuqhuma engu-1500V 3P T2 ye-air conditioner | LKX-PV

I Idivayisi Evikelayo Yokukhuphuka Kohlobo 2 lwe-SPD 20–40kA 1500V DC 3-Pole (LKX-PV) yenzelwe izinhlelo zamandla ze-photovoltaic kanye ne-DC ezinamandla aphezulu, enikeza isivikelo esithembekile seKlasi II ngokumelene nokweqisa kwamandla kagesi okudlulayo, ukukhuphuka kokushintsha, kanye nemisinga yombani ebangelwayo. amamojula e-MOV anamandla aphezulu, ukuvikelwa kokuxhuma ukushisa, kanye nezifunda eziphendula ngokushesha, kuqinisekisa ukusebenza okuzinzile kwesikhathi eside ama-PV arrays amakhulu, amabhokisi okuhlanganisa, ama-central/string inverters, amakhabethe okusabalalisa e-DC, izinhlelo zokugcina amabhethri, kanye nezitshalo zelanga ze-1500V DC.

imininingwane yomkhiqizo

Incazelo Yemodeli

Isimiso somkhiqizo kanye nezimo zokusebenza

1.Ihlangana nokuhlolwa kwe-SPD kwe-ClassⅡ (8/20μs)

2. Ngokusekelwe kubuchwepheshe be-zinc oxide

3. Ukusebenzisa i-34S MOV, umkhawulo ophezulu uzoba ngu-8/20μs 40kA

4. Akukho ukugeleza okuqhubekayo kwemvamisa yamandla

5. Izinga lokushisa lendawo yokusebenza lingu-40°C~+80°C

6. Umsebenzi wokusayina okude ungowokuzikhethela.

7. Uma umkhiqizo uwela, ifasitela eliluhlaza liphenduka libe bomvu futhi ukusayina okukude kunikeza umsebenzi we-alamu okukude

Ukubukeka kwangaphandle kanye nobukhulu bokufakwa

Izinto okufanele uzicabangele lapho ufaka

1. Ngaphambi kokufaka, qiniseka ukuthi ugesi unqanyuliwe. Ukusebenza ngenkathi unamandla akuvunyelwe ngokuphelele.

2. Kunconywa ukufaka i-fuse noma i-circuit breaker ngokulandelana engxenyeni engaphambili yemojuli yokuvikela ukukhuphuka.

3. Landela umdwebo wokufaka ukuze uxhumeke ngesikhathi sokufakwa. I-DC+ iyisigxobo esihle, i-DC- iyisigxobo esibi, kanti i-PE iyintambo yomhlabathi. Gwema ukuxhumeka okungalungile. Ngemva kokufakwa, vala iswishi ye-circuit breaker (noma i-fuse) bese uhlola ukuthi isimo sokusebenza sijwayelekile yini.

4. Ngemva kokufakwa, faka imodyuli endaweni yayo bese uqinisekisa ukuthi imodyuli yokuvikela ukukhuphuka isebenza kahle.

5. Ngesikhathi sokusebenzisa, hlola njalo imodyuli yokuvikela ukukhuphuka bese uhlola isimo sewindi lokubonisa amaphutha. Uma iwindi lokubonisa amaphutha liba bomvu noma uma i-remote signaling terminal ikhipha isignali ye-alamu, kubonisa ukungasebenzi kahle kwemodyuli yokuvikela ukukhuphuka, okufanele ilungiswe ngokushesha noma ishintshwe.

6. Amamojula okuvikela ukukhuphuka kwamandla axhunywe ngokufana kufanele afakwe ngokufana. Izintambo zokuxhuma kumele ziqine, zithembeke, zibe zimfushane, zibe zijiyile, futhi ziqonde.
