Anchinja chevhu, iyo inodanwawochinja pasi, chigadziriso chemuchina chinoshandiswa kugadzika dunhu nemaune.
Pasi pemamiriro ezvinhu asina kujairika (akadai sedunhu pfupi), switching yepasi inogona kutakura yakatarwa yakatemerwa pfupi yedunhu ikozvino uye inoenderana peak ikozvino mukati menguva yakatarwa; Nekudaro, pasi pemamiriro ekushanda akajairika, hazvidiwi kutakura yakayerwa ikozvino.
Iyo yepasi switch uye yekubvisa switch kazhinji inosanganiswa kuita imwe mudziyo. Panguva ino, mukuwedzera kune iyo huru yekubata, iyo yekuzviparadzanisa switch inoshongedzerwawo nepasi switch yekumisa imwe magumo eiyo yekuzviparadzanisa switch mushure mekuvhurwa. Iyo huru yekubata uye yekuvhuvhuta inotenderedza inowanzo kuvharirwa mechanically nenzira yekuti earthing switch haigone kuvharwa kana switch yekuzviparadzanisa nevamwe yakavharwa uye iyo huru yekusangana haigone kuvharwa kana pasi switch yakavharwa.
Earthing switch zvinoenderana nechimiro inogona kukamurwa kuita yakavhurika uye yakavharwa marudzi maviri. Iyo conductive sisitimu yeiyo yekutanga inooneswa kumhepo ine ivhu switch yakafanana neiyo yega switch, uye iyo conductive system yeiyo yekupedzisira yakavharirwa muchaji SF. Kana mafuta uye zvimwe zvinodzivirira media.
Iyo earthing switch inoda kuvhara iyo pfupi yedunhu ikozvino, uye inofanirwa kunge iine imwe pfupi yedunhu yekuvhara kugona uye inoshanduka uye yekudziya kugadzikana. Nekudaro, hazvidi kutyora mutoro wazvino uye pfupi wedunhu ikozvino, saka hapana arc yekudzima mudziyo. Mugumo wezasi webanga unowanzobatanidzwa kunzvimbo yepasi kuburikidza nemushanduri wezvino. Ikozvino transformer inogona kupa chiratidzo chekudzivirira relay.
Ivhu rinochinja rezvimiro zvakasiyana rakakamurwa kuita danda rimwechete, kaviri danda uye matatu pole. Iro danda rimwechete rinoshandiswa chete mune zvisina kwazvakarerekera pasi masisitimu, nepo mapango maviri neatatu anoshandiswa mune kwaakarerekera asina kuvhurika masisitimu uye kugovera imwechete yekushandisa nzira yekushanda.
