Ulawulo lwemizi-mvelisoI-12KV VS1 i-vacuum circuit breaker yangaphandle ye-VCB

I-HWZN63(VS1) i-outdoor vacuum circuit breaker (ebizwa ngokuba yi-circuit breaker) sisixhobo sokusasaza sangaphandle esine-voltage elinganisiweyo ye-12kV kunye ne-ac yesigaba sesithathu ye-50Hz. Isetyenziswa kakhulu kwi-load current, i-overload current kunye ne-short circuit current kwinkqubo yamandla. Ifanelekile ukukhusela nokulawula iinkqubo zokusasaza umbane kwizikhululo ezincinci kunye namashishini emizi-mveliso kunye nemigodi.

Esi siqhekezi sesekethe sineempawu zobukhulu obuncinci, ubunzima obulula, ukuthintela ukufuma, ukugcinwa komvundla njalo njalo, sinokuziqhelanisa neemeko zemozulu ezinzima kunye nendawo engcolileyo.

1. Ikhabhinethi yeswitshi ye-4000A yangoku elinganisiweyo kufuneka iqinise ukupholisa komoya
2 Xa umsinga wokuqhekeza isekethe emfutshane ungaphantsi kwe-40KA, Q = 0.3s; xa umsinga wokuqhekeza isekethe emfutshane ungaphezulu okanye ulingana ne-40KA, Q = 180s
