Kudzora maindasitiri12KV VS1 yekuvhuvhuta dunhu rekunze VCB

HWZN63(VS1) outdoor vacuum circuit breaker (ichazonzi circuit breaker) imuchina wekugovera magetsi kunze une voltage ye12kV uye three-phase ac ye50Hz. Inonyanya kushandiswa pakupinza magetsi, overload current uye short circuit current mu power system. Yakakodzera kuchengetedza nekudzora masisitimu ekugovera magetsi mu substations nemaindasitiri nemakambani emigodhi.

Iyi circuit breaker ine hunhu hwehukuru hudiki, huremu hwakareruka, inodzivirira kutonhora kwemvura, kuchengetedza tsuro nezvimwewo, inogona kuchinjika nemamiriro ekunze akaoma uye nzvimbo ine tsvina.

1. Kabhineti yekuchinja ye4000A inoyerwa ikozvino inofanira kusimbisa kutonhora kwemhepo
2 Kana current ye breaking circuit yakayerwa iri pasi pe 40KA, Q = 0.3s; kana current ye breaking circuit yakayerwa yakakura kupfuura kana yakaenzana ne 40KA, Q = 180s
