Mfundo ya chitetezo cha overvoltage cha zida zotseketsa pafupipafupi

Muyeso wachitetezo cha overvoltage ndikugwiritsa ntchito varistor molumikizana ndi malekezero awiri a chingwe chamagetsi. Varistor imakhudzidwa kwambiri ndi magetsi. Pamene voteji imaposa mtengo wina, mtengo wake wotsutsa nthawi yomweyo umakhala wochepa, kotero kuti panopa ukuwonjezeka kwambiri. Pamene chipangizo ali overvoltage, izo adzaphwanya varistor, kotero kuti malekezero onse a magetsi adzakhala osagwirizana, motero kuteteza kumbuyo mapeto a magetsi ndi kupewa chiopsezo overvoltage, amene amatumikira cholinga cha overvoltage chitetezo. Malingana ngati ma varistor amasinthidwa kawirikawiri, zipangizozi zingagwiritsidwe ntchito nthawi zonse, koma tifunika kubwezeretsanso nthawi, zomwe zimakhala zovuta kugwira ntchito. Ngati sichingasinthidwe panthawi yake, dera lazida likhoza kuwonongeka, ndipo ngakhale moto ukhoza kuchitika pazovuta kwambiri.

Chitetezo cha overvoltage ndi undervoltage chitetezo cha high-frequency kuzimitsa zipangizo ndizofunikira kwambiri. Malingana ngati mtengo wamagetsi wa zida zathu ukupitirira malire, kuwala kwachitsulo pazida kumawunikira ndipo alamu idzatulutsidwa yokha. Panthawiyi, ogwira ntchito ayenera kuchitapo kanthu mwamsanga kuti apewe Zomwe zili bwino komanso zimalepheretsa kuti pakhale mavuto monga moto. Ndizotetezeka komanso zothandiza.
