Ama-wholesale angu-40.5KV HW-12 angaphandle ane-voltage ephezulu ye-AC vacuum circuit breaker ama-VCB circuit breaker yueqing

1. Ikhabhinethi yokushintsha yamanje engu-4000A elinganisiwe idinga ukuqinisa ukupholisa komoya
2 Uma umkhawulo wokuphuka kwesekethe esifushane ungaphansi kuka-40KA, Q = 0.3s; uma umkhawulo wokuphuka kwesekethe esifushane ungaphezulu noma ulingana no-40KA, Q = 180s

Isifinyezo

I-hW-12 outdoor high voltage AC vacuum circuit breaker iyithuluzi lokusabalalisa i-current yangaphandle le-current eline-voltage elinganisiwe engu-40.5k kanye ne-50H three-phase AC. Isetshenziswa kakhulu ekunqamuleni nasekuvaleni inethiwekhi yokusabalalisa. i-load current, i-overload current kanye ne-short circuit current ohlelweni lwamandla. ifanele ukuvikela nokulawula izinhlelo zokusabalalisa ugesi zeziteshi ezincane kanye namabhizinisi ezimboni kanye nawezimayini. ifanele amagridi kagesi asemakhaya kanye nezindawo ezisetshenziswa njalo. Ifaneleka kakhulu izidingo zenethiwekhi yasemadolobheni kanye nenethiwekhi yasemakhaya.
