Izilawuli zezimboniI-VCB ye-vacuum circuit breaker yangaphandle engu-12KV VS1

I-HWZN63(VS1) i-vacuum circuit breaker yangaphandle (ebizwa ngokuthi i-circuit breaker) iyimishini yokusabalalisa yangaphandle ene-voltage elinganisiwe engu-12kV kanye ne-ac yesigaba ezintathu engu-50Hz. Isetshenziswa kakhulu ku-load current, i-overload current kanye ne-short circuit current ohlelweni lwamandla. Ifanele ukuvikela nokulawula izinhlelo zokusabalalisa ugesi eziteshini ezincane kanye nasemabhizinisini ezimboni nawezimayini.

Le circuit breaker inezici zobukhulu obuncane, isisindo esincane, ukuvimbela ukuminyana, ukunakekelwa konogwaja njalo njalo, ingakwazi ukuzivumelanisa nezimo zezulu ezinzima kanye nendawo engcolile.

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
