Yopangidwa ku China 80A Over Voltage Protector Single Phase Automatic Under Voltage Protector

Choteteza magetsi ndi njira yogwiritsira ntchito magetsi ya magawo atatu kapena chida chowunikira komanso choteteza zida zamagetsi za magawo atatu. Chimaphatikiza chiwonetsero cha magetsi cha magawo atatu, chitetezo cha overvoltage, chitetezo cha undervoltage, chitetezo cha kulephera kwa magawo (chitetezo cha kulephera kwa magawo), chitetezo cha kusalingana kwa magetsi a magawo atatu, ndi chitetezo cha magawo (chitetezo cha dislocation). Chingagwiritsidwe ntchito kuyang'anira magawo ofunikira (voltage, gawo, kutayika kwa magawo, gawo) mu dongosolo lamagetsi la magawo atatu. Chikhoza kutumiza zizindikiro za alamu panthawi yake chifukwa cha zinthu zachilendo za magetsi a magawo atatu zomwe zingawononge magwiridwe antchito otetezeka komanso odalirika a dongosolo lamagetsi ndi zida, kuti makina owongolera athe kugwira bwino ntchito zida zamakina zisanawonongeke kwambiri.
