ZN73S-24 Series (VCB)

ZN73S-24 Indoor high voltage vacuum circuit breaker yakakodzera michina yekugovera mukati ye24kv, 3 phase AC 50Hz, inonyanya kushandiswa kupwanya nekuvhara load current, over current uye short-circuit current mucircuit, inoita basa rekudzora nekudzivirira, uye ndiyo midziyo mikuru yeswitchgear yepakati nepakati.

Inoshandiswa kudzivirira nekudzora masisitimu ekugovera magetsi ezviteshi zvemagetsi, mabhizinesi, maindasitiri nemabhizinesi emigodhi. Yakakodzera magrid emagetsi ekumaruwa nenzvimbo dzinoshanda kakawanda, kunyanya nekuda kwekuchinja kwenetwork yemaguta nekurima.

Ruzivo rweChigadzirwa

Hunhu Hukuru hweMabasa

● Circuit breaker inoshandisa copper-chromium contact material uye magnetic field contact structure yakaita sekapu. Kupera kwemagetsi kwecontacts kudiki, dielectric insulation strength yakagadzikana, kupora mushure me arc kunokurumidza, cut-off level yakaderera, breakability yakasimba, uyehupenyu hwemagetsi hwakareba.

● Nzira yekushandisa iyi inzira yekuchengetedza simba yechitubu yakarongwa mundege, ine mabasa ekuchengetedza simba nemaoko uye mabasa ekuchengetedza simba remagetsi kuti mashandiro ecircuit breaker ave akavimbika.
