IP20 Kusinthana 18W 24W AC Power Adapter

Chidule cha kuyesa kwachitetezo cha overcurrent

Mu mndandanda wa adaputala zamagetsi zoyendetsedwa, zonse zomwe zimanyamula zimayenda kudzera mu chubu chowongolera. Pakachulukirachulukira, kulipiritsa nthawi yomweyo kwa ma capacitor akulu kapena kutulutsa kwafupipafupi, chubu chowongolera chidzayenda kwambiri. Makamaka, pamene linanena bungwe voteji ndi yochepa-circuited mosasamala, onse athandizira voteji anawonjezera kusonkhanitsa ndi kuwombera mitengo ya mndandanda malamulo chubu, kuti kutentha mu chubu ukuwonjezeka kwambiri. Ngati palibe chitetezo choyenera, chitolirocho chidzawotchedwa nthawi yomweyo. Kutentha kwa kutentha kwa transistor ndi kochepa kwambiri kuposa fuse, kotero chotsiriziracho sichingagwiritsidwe ntchito kuteteza choyambirira. Wowongolera mndandanda uyenera kutetezedwa ndi dera lotetezedwa lamagetsi lomwe limagwira ntchito mwachangu. Dera lodzitchinjiriza lamagetsi litha kugawidwa m'mitundu yocheperako komanso mtundu wodulidwa. Zoyambazo zimaletsa machubu owongolera omwe ali pansi pa mtengo wina wotetezeka, pomwe chomalizacho chimadula nthawi yomweyo chubu chowongolera ngati chikuchulukirachulukira kapena ngozi yayifupi kumapeto.

Adapter yamagetsi yoyendetsedwa ndi DC imapanga voteji yamphamvu kwambiri, kenako imalumikiza gawo limodzi ndi cathode ndi linalo ku anode. Munda wamphamvu wamagetsi umapangidwa pakati pa cathode ndi anode, ndipo gawo lamagetsi pamitengo iwiriyo limaposa mphamvu yodziwika, ndiyeno lidzatulutsa. Pali ionization kuzungulira munda wamagetsi, ndiyeno pali ma electron ambiri ndi ma ion. Patapita kanthawi, mphepo yamphamvu kwambiri yamagetsi imamveka kuzungulira malo amagetsi. Powala pang'ono, wofiirira wofiyira - korona wabuluu amatha kuwoneka mozungulira. Komanso, kuzungulira munda wamagetsi, padzakhala phula yambiri, fumbi ndi tinthu tating'ono tomwe timaphatikizana ndi ma ion kapena ma electron, omwe amasunthira kumitengo yomwe ikugwiritsidwa ntchito ndi mphamvu yamagetsi. Unyinji wa electron ndi wochepa kwambiri, koma umayenda mofulumira kwambiri, choncho makamaka umakhala ndi particles zoipa.
