Ntchito

Chomangiracho chimalumikizidwa pakati pa chingwe ndi pansi, nthawi zambiri mofanana ndi zida zotetezedwa.Womangayo amatha kuteteza bwino zida zoyankhulirana.Mphamvu yamagetsi ikachitika, womangayo adzachitapo kanthu ndikuteteza.Pamene chingwe choyankhulirana kapena zipangizo zikuyenda pansi pamagetsi ogwira ntchito, chomangirira sichidzagwira ntchito, ndipo chimatengedwa ngati dera lotseguka pansi.Kamodzi voteji mkulu kumachitika ndi kutchinjiriza wa zida zotetezedwa ali pangozi, womangidwa adzachitapo kanthu mwamsanga kutsogolera mkulu-voteji mafunde panopa pansi, potero kuchepetsa matalikidwe voteji ndi kuteteza kutchinjiriza zingwe kulankhulana ndi zipangizo.Pamene overvoltage ikutha, womangidwayo amabwerera mwamsanga kumalo ake oyambirira, kotero kuti mzere wolankhulana ukhoza kugwira ntchito bwino.

Choncho, ntchito yaikulu ya womangayo ndi kudula akuwukira otaya yoweyula ndi kuchepetsa overvoltage mtengo wa zida zotetezedwa mwa ntchito ya parallel kutulutsa kusiyana kapena resistor nonlinear, potero kuteteza mzere kulankhulana ndi zipangizo.

Zomanga mphezi zitha kugwiritsidwa ntchito osati kungoteteza kumagetsi okwera kwambiri opangidwa ndi mphezi, komanso kuteteza motsutsana ndi ma voltages apamwamba.

Chidziwitso Chachikulu cha Electric Arrester

Tanthauzo: Ikhoza kumasula mphezi kapena mphamvu zonse zogwiritsira ntchito mphamvu zowonjezera mphamvu, kuteteza zipangizo zamagetsi kuti zisapitirire pang'onopang'ono (mphezi yamagetsi, kuwonjezereka kwamagetsi, kugwedezeka kwamagetsi, mphamvu yafupipafupi yamagetsi yamagetsi), ndipo imatha kudula freewheeling popanda kuchititsa Chipangizo chamagetsi chomwe chimapangitsa kuti dera laling'ono likhale dongosolo pansi.

Ntchito: Pamene overvoltage ikuchitika, voteji pakati pa ma terminals awiri a womangidwa sadutsa mtengo wotchulidwa, kuti zipangizo zamagetsi zisawonongeke ndi kuwonjezereka;pambuyo overvoltage ntchito, dongosolo akhoza mwamsanga kubwerera ku mkhalidwe wabwinobwino kuonetsetsa yachibadwa magetsi a dongosolo.

Zizindikiro zingapo zomwe zimakhudzidwa ndi chomangira mphamvu
(1) Khalidwe lachiwiri la Volt: limatanthawuza mgwirizano womwe uli pakati pa magetsi ndi nthawi.
(2) Kuthamanga kwa ma frequency amphamvu: Kumatanthawuza mphamvu yamagetsi yamagetsi afupipafupi omwe akuyenda pambuyo pa voteji yamphezi kapena kutulutsa kopitilira muyeso, koma voteji yamagetsi imagwirabe ntchito pa womanga.
(3) Kuthekera kodzibwezeretsa kwa mphamvu ya dielectric: mgwirizano pakati pa mphamvu ya dielectric ya zida zamagetsi ndi nthawi, ndiko kuti, kuthamanga kwa kuchira ku mphamvu yapachiyambi ya dielectric.
(4) Mphamvu yamagetsi ya womangayo: mphamvu yayikulu yamagetsi yamagetsi yomwe kusiyana kungapirire pambuyo pa ma frequency a frequency freewheeling panopa kuwoloka ziro kwa nthawi yoyamba, ndipo sikudzachititsa kuti arc iyambe kulamulira, yomwe imadziwikanso kuti arc voltage.
