I-Wholesale 40.5KV HW-12 yangaphandle ene-voltage ephezulu ye-AC vacuum circuit breaker VCB circuit breakers yueqing

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

Isishwankathelo

I-hW-12 yangaphandle ene-high voltage AC vacuum circuit breaker sisixhobo sokusasaza sangaphandle se-current current esine-voltage elinganisiweyo ye-40.5k kunye ne-50H three-phase AC. Isetyenziswa kakhulu ekuqhawuleni nasekuvaleni inethiwekhi yokusasaza. i-load current, i-overload current kunye ne-short circuit current kwinkqubo yombane. ifanelekile ukukhusela nokulawula iinkqubo zokusasaza umbane zezikhululo ezincinci kunye namashishini emizi-mveliso kunye nemigodi. ifanelekile kwiigridi zombane zasemaphandleni nakwiindawo ezisetyenziswa rhoqo. Ifanelekile ngokukodwa kwiimfuno zenethiwekhi yedolophu kunye nenethiwekhi yasemaphandleni.
