3, Zviviriro zvishanu
1, Mushure mekunge vacuum circuit breaker trolley mu high-voltage switch cabinet yakavharwa panzvimbo yekuedza, trolley circuit breaker haigoni kupinda panzvimbo yekushanda.(Dzivisa pakuvhara mutoro)
2, Kana banga rekugadzika mu-high-voltage switch cabinet rakavharwa, trolley circuit breaker haigoni kupinda panzvimbo yekushanda yekuvhara.(Dzivisa kuvhara newaya yekudzika)
3, Kana iyo vacuum circuit breaker mune yakakwira-voltage switch kabati yakavharwa, magonhi ekumberi nekumashure epaneru kabati anovharwa nemusuwo wekhabhineti nemichina pabanga rekumisa.(Dzivisa kupinda mukamuri yekugara nekukanganisa)
4, Vacuum circuit breaker mu high-voltage switch cabinet yakavharwa panguva yekushanda, uye banga rekuisa pasi harigoni kuvharwa uye kuiswa mukushanda.(Dzivisa kuisirwa magetsi uye waya yekudzika)
5, Vacuum circuit breaker mu high-voltage switch cabinet haigoni kubuda panzvimbo yekushanda yetrolley circuit breaker kana yakavharwa kuti ishande.(Dzivisa kurodha broach brake)
