Lub luag haujlwm ntawm Varistor
Apr 22, 2021
Dab tsi yog siv varistor? Tus yam ntxwv loj tshaj plaws ntawm tus neeg hloov pauv yog tias thaum qhov hluav taws xob siv rau nws qis dua nws qhov pib&"UN"&"; Thaum qhov hluav taws xob ntau dua UN, nws qhov kev tiv thaiv Tus nqi ua me dua, yog li qhov tam sim no ntws los ntawm nws nce nrawm dua, thiab cuam tshuam rau lwm qhov kev hloov pauv tsis hloov pauv ntau, yog li txo qhov cuam tshuam ntawm overvoltage ntawm qhov txuas txuas ntxiv. Kev siv txoj haujlwm no, qhov txawv txav overvoltage uas feem ntau tshwm sim hauv Circuit Court tuaj yeem tiv thaiv tau, thiab lub Circuit Court tuaj yeem tiv thaiv los ntawm kev puas tsuaj ntawm overvoltage.
Piv txwv li, lub tshuab hluav taws xob hluav taws xob ntawm peb lub TV xim hauv tsev siv zinc oxide varistor. Tus ntsuas hluav taws xob hloov hluav taws xob siv ntawm no yog 470V. Thaum tus nqi siab tshaj (tus nqi tsis muaj txiaj ntsig) ntawm qhov hloov pauv qhov hluav taws xob ntau dua 470V, qhov ntsuas hluav taws xob Tus ntsuas hluav taws xob yog txhawm rau cuam tshuam nws cov yam ntxwv clamping, rub qhov hluav taws xob ntau dhau qis, thiab cia ua haujlwm tom ntej hauv kev nyab xeeb.
