Tsanangudzo Pfupi:

Iyo HM4 yepakati-voltage circuit breaker inoshandisa sulfur hexafluoride (SF6) gasi searc-kudzimisa uye insulating medium. SF6 gasi ine hunhu hwakatsetseka hwekutyora, uye kana ichipwanya ikozvino mairi, hapana chazvino chekucheka chiitiko uye hapana overvoltage yekushanda inogadzirwa. Iyi yakanakisa hunhu inovimbisa kuti muparadzi wedunhu ane hupenyu hurefu hwemagetsi. Uyezve, panguva yekushanda, haina kukanganisa pakuvhunduka kwemidziyo, dielectric level, uye kushushikana kwemafuta. Iyo pole column yecircuit breaker, kureva, iyo arc-yekudzimisa kamuri chikamu, inochengetedza-isina yakavharwa system yehupenyu. Hupenyu hwayo hwekuisa chisimbiso hunoenderana neIEC 62271-100 uye CEI17-1 zviyero.
