LOTO- Magetsi akanthawi

Kukhazikitsa kwa "makina amodzi, bokosi limodzi, switch imodzi, kutayikira kamodzi" sikukakamizidwa kuti kugwiritsidwe ntchito kwakanthawi kwamagetsi.

"Bokosi limodzi, makina amodzi, switch imodzi, kutayikira kamodzi" amatanthauza kufotokozera kwa magetsi akanthawi, zomwe zikutanthauza kuti zida zonse zamakina ziyenera kukhala ndi bokosi losinthira losiyana, bokosi losinthira liyenera kukhazikitsidwa ndi chosinthira cha mpeni (chosinthira chodzipatula) ndi choteteza kutayikira, chosinthira chimangoyika zida zamakina chimodzi zokha, chosinthira chimagwira ntchito molakwika komanso ngozi. Monga ngozi iyi, Gong ndi ogwira ntchito ena motsatira "mafotokozedwe aukadaulo achitetezo chamagetsi kwakanthawi pamalo omanga", bokosi logawa ndi bokosi losinthira, motsatira "bokosi limodzi makina amodzi switch imodzi kutayikira kamodzi", zidzakongoletsa zida zamakina za ogwira ntchito ndi zida zamagetsi zomwe zayikidwa padera, ngoziyo ingathenso kupewedwa.

Bokosi logawa mphamvu kwakanthawi ndi bokosi losinthira

Malinga ndi Nkhani 8.1 ya Technical Specification for Temporary Electricity Safety on Construction Site, ma distribution box ndi switch box configuration ziyenera kukwaniritsa zofunikira izi: 1. Njira yogawa magawo atatu yagwiritsidwa ntchito. Chomwe chimatchedwa kuti ma distribution a magawo atatu ndi kugawa konse, kugawa, switch box, ma distribution a magawo atatu, ma distribution a magawo atatu, sitepe ndi sitepe, ku "makina, chipata, kutayikira, bokosi, loko".

Gwiritsani ntchito njira yoteteza ya TN-S zero. Njira yoteteza ya TN-S zero yolumikizira ndi mzere wa 32 wogwirira ntchito ndipo njira yoteteza ya 0 yolumikizira ndi zero yolumikizira yokhazikika padera. 3. Gwiritsani ntchito njira yoteteza ya 2. Chitetezo cha 2. Njira yoteteza kutayikira kwa madzi imatanthauza kuti njira yamagetsi iyenera kukhala ndi chitetezo cha 2. Njira yotetezera kutayikira kwa madzi m'bokosi lalikulu logawa ndi bokosi losinthira. Mphamvu yoteteza kutayikira kwa madzi ndi nthawi yoteteza kutayikira kwa madzi m'bokosi lalikulu logawa ndi bokosi losinthira ziyenera kugwirizanitsidwa bwino kuti zikhale chitetezo chokhazikika komanso chogawanika.
