Zida zosinthira

Kodi switchgear ndi chiyani?

Chosinthira magetsi ndi mtundu wa zida zamagetsi. Mzere wakunja umalowa kaye mu chosinthira chachikulu chowongolera mu kabati, kenako umalowa mu chosinthira cha sub-control, ndipo nthambi iliyonse imayikidwa malinga ndi zosowa zake. Monga zida, chowongolera chokha, chosinthira cha maginito a mota, ma contactor osiyanasiyana a AC, ndi zina zotero, zina zimakhala ndi makabati osinthira a chipinda chamagetsi ndi makabati osinthira a chipinda chamagetsi otsika, mabasi amagetsi okwera, monga malo opangira magetsi, ndi zina zotero, ndipo zina zimakhala ndi chitetezo chochepa cha kayendedwe ka magetsi pazida zazikulu.

"Njira Zisanu Zopewera" za High Voltage Switchgear

1. Pewani kutseka mukanyamula katundu: Trolley ya vacuum circuit breaker yomwe ili mu kabati ya switch yamphamvu ikatsekedwa pamalo oyesera, trolley circuit breaker singathe kulowa pamalo ogwirira ntchito.

2. Pewani kutseka ndi waya wothira pansi: Mpeni wothira pansi womwe uli mu kabati yosinthira magetsi amphamvu kwambiri ukakhala wotsekedwa, chothyolera magetsi cha trolley sichingatsekedwe.

3. Pewani kulowa mwangozi kwa nthawi yogwira ntchito: Pamene chotsegula magetsi cha vacuum mu kabati yosinthira magetsi amphamvu chikutsekedwa, chitseko chakumbuyo cha panelo chimatsekedwa ndi makinawo pa mpeni wogwetsa pansi ndi chitseko cha kabati.

4. Pewani kukhazikika kwa magetsi: Chotsekera magetsi cha vacuum chomwe chili mu switchgear yamagetsi amphamvu chimatsekedwa chikagwira ntchito, ndipo mpeni wokhazikika sungaikidwemo.

5. Letsani switch yonyamula katundu: chotsegula magetsi cha vacuum chomwe chili mu switchgear yamagetsi amphamvu sichingatuluke pamalo ogwirira ntchito a trolley circuit breaker chikagwira ntchito.
