Ihoyile 40.5KV HW-12 yangaphandle yombane ephezulu AC vacuum isaphuli sesekethe VCB izaphuli zesekethe yueqing

1. Ikhabhinethi ye-4000A ehlaziyiweyo yangoku idinga ukuqinisa ukupholisa umoya
2 Xa i-rerated short-circuit breaking current ingaphantsi kwe-40KA, Q = 0.3s; xa ireyithingi ye-short-circuit breaking current inkulu okanye ilingana ne-40KA, Q = 180s

Isishwankathelo

I-hW-12 yangaphandle yombane ophezulu we-AC i-vacuum breaker yesekethe yi-currentransformer yangaphandle yesixhobo sokusasaza esinomthamo olinganisiweyo we-40.5k kunye ne-50H isigaba sesithathu se-AC. Ikakhulu isetyenziselwa ukuhanjiswa kwenethiwekhi kunye nokuvalwa. ukulayisha okwangoku, ukulayisha ngokugqithisileyo ngoku kunye nesekethe emfutshane yangoku kwinkqubo yamandla. ifanelekile ukukhuselwa kunye nokulawula kwiinkqubo zokusasazwa kwamandla ezikhululo ezincinci kunye namashishini oshishino kunye nemigodi. ilungele iigridi zamandla zasemaphandleni kunye neendawo ezisebenza rhoqo. Ngokukodwa ngokufanelekileyo kwiimfuno zothungelwano lwasezidolophini kunye nothungelwano lwasemaphandleni
