Izvi zvinonyanya kufunga nezvekusarudza kweiyo relay kuchengetedzwa chiito. Iyo yakakwirira-voltage side quick-break kuchengetedzwa inonyanya kuchengetedza kukanganisa kwakakomba kwekunze kwe transformer. Iyo pfupi-dunhu kukosha kwazvino kweiyo renji hakuchinje zvakanyanya uye kwakaenzana, izvo zvichawedzera huwandu hwepamusoro-voltage divi rinokurumidza-kupwanya kudzivirira kune yakaderera-voltage inobuda mutsetse, nokudaro kurasikirwa kusarudza. Kudzivirirwa kunonyanya kuvimbika mushure mekurasikirwa kwekusarudza, asi kunounza kusagadzikana kune mvumo. Semuenzaniso, maindasitiri mazhinji iye zvino ane 10KV general power distribution room (10KV busbar + outgoing circuit breaker), uye workshop yega yega ine yakaderera-voltage simba rekugovera kamuri (ring network cabinet + Transformer), kana muparadzi wedunhu asingapukunyuki. pfupi-yedunhu ikozvino pane yakaderera-voltage divi retransformer, ichaita yakaderera-voltage main switch, (ring main unit load switch fuse), uye iyo yakakwira-voltage yedunhu breaker ichashanda, izvo zvinokonzeresa kusagadzikana kune oparesheni. .
