Zotsatira Zakuwotcha Kwa Varistor Ndi Chiyani?

Varistor ndi chopinga chomwe chili ndi mawonekedwe osagwirizana ndi volt-ampere.Monga thermistor, ndi gawo lopanda mzere.Varistor imakhudzidwa ndi magetsi.M'kati mwamtundu wina wamagetsi, kukana kwake kumasintha ndi kusintha kwa magetsi.

Varistorsamagwiritsidwa ntchito kwambiri mu zida zapakhomo, zamagetsi ogula, mafakitale ndi magawo ena chifukwa cha zabwino zawo.Mwachitsanzo, mavuvuni a microwave, ma air conditioners, etc. onse ali ndi ma varistors.Kutentha kwa ntchito kwa varistor ndi -40 ° C ~ + 85 ° C.Varistor imakhala ndi magwiridwe antchito okhazikika.Ikagwira ntchito mosalekeza kwa maola a 1000 pa kutentha kwa +40 ° C (± 2 ° C) ndi chinyezi chachifupi cha 90%, kenako ndikusintha kukhala kutentha kwa firiji, kusintha kwamagetsi kwa varistor yoyesedwa ndi yocheperako. 10%.

Pofika chilimwe, kutentha kumakwera kwambiri, ndipo varistor nthawi zambiri imakhala ndi mavuto pamene ikugwira ntchito kutentha kwakukulu.Ndipotu, palibe vuto ndi varistor kugwira ntchito pa kutentha kwakukulu kwa nthawi yochepa.Pamene varistor ikugwira ntchito pa kutentha kwa nthawi yaitali, kutsika kwapansi kwa mitsempha ya varistor kumakula pang'onopang'ono, kuthamanga kwa madzi kumawonjezeka ndikuyenda kumalo ofooka, ndipo zinthu za malo ofooka zimasungunuka kupanga dzenje laling'ono. , madzi akuluakulu amatsanuliridwa mosalekeza mu dzenje laling'ono kuti apange kutentha kwakukulu, zomwe zidzachititsa kuti varistor azitentha ndikugwira moto.

Choncho, pogwiritsira ntchito zipangizo zapakhomo, makamaka zida zamphamvu kwambiri, tiyenera kumvetsera kutentha kozungulira chipangizocho kuti chisakhale chokwera kwambiri, ndikusunga kutentha kwabwino kuti tipewe ngozi zoopsa.

Sankhani wopanga wodalirika pogula varistor angapewe mavuto ambiri osafunikira.JYH HSU (kapena Dongguan Zhixu Electronics) sikuti ili ndi mitundu yonse ya ma capacitor a ceramic okhala ndi mtundu wotsimikizika, komanso imaperekanso kutsatsa kopanda nkhawa.JEC mafakitale wadutsa ISO9001: 2015 khalidwe kasamalidwe dongosolo chitsimikizo;JEC chitetezo capacitors (X capacitors ndi Y capacitors) ndi varistors adutsa chiphaso cha mayiko osiyanasiyana;Ma capacitor a JEC ceramic, ma capacitor amafilimu ndi ma super capacitors amagwirizana ndi zizindikiro zotsika za kaboni.
