Menene Sakamakon Zazzaɓi Na Varistor?

A varistor resistor ne mai sifofin volt-ampere marasa kan layi.Kamar thermistor, abu ne wanda ba na layi ba.Varistor yana kula da wutar lantarki.A cikin takamaiman kewayon ƙarfin lantarki, juriyarsa yana canzawa tare da canjin ƙarfin lantarki.

Varistorana amfani da su sosai a cikin kayan aikin gida, na'urorin lantarki, masana'antu da sauran fannoni ta hanyar fa'idodin nasu.Misali, tanda microwave, kwandishan, da sauransu duk suna da varistors.Yanayin zafin aiki na varistor shine -40 ° C ~ + 85 ° C.A varistor yana da ingantaccen aiki.Bayan ya ci gaba da aiki har tsawon sa'o'i 1000 a zafin jiki na +40 ° C (± 2 ° C) da kuma yanayin zafi na kusan 90%, sannan ya canza zuwa yanayin zafin jiki, canjin wutar lantarki na varistor da aka gwada bai kai ba. 10%.

Tare da zuwan lokacin rani, yawan zafin jiki yana karuwa da girma, kuma varistor yana da matsala ga matsalolin lokacin aiki a babban zafin jiki.A gaskiya ma, babu matsala tare da varistor aiki a babban zafin jiki na ɗan gajeren lokaci.Da zarar varistor yayi aiki akan kewayon zafin jiki na dogon lokaci, ƙananan juriya na layi na varistor yana ƙaruwa sannu a hankali, ɗigon ruwa yana ƙaruwa kuma yana gudana zuwa cikin maƙasudin rauni, kuma kayan da ke cikin rauni ya narke don samar da rami mai gajeren lokaci. , ana ci gaba da zuba wani katon magudanar ruwa a cikin ramin gajeren zango don samar da zafi mai zafi, wanda zai sa varistor ya kone kuma ya kama wuta.

Don haka, lokacin amfani da kayan aikin gida, musamman na'urori masu ƙarfi, dole ne mu mai da hankali ga yanayin zafi a kusa da na'urar don kada ya yi girma sosai, kuma a kula da yanayin zafin jiki na yau da kullun don guje wa haɗari masu haɗari.

Zaɓi ƙwararrun masana'anta lokacin siyan varistor na iya guje wa matsala mai yawa mara amfani.JYH HSU (ko Dongguan Zhixu Electronics) ba wai kawai yana da cikakkun samfuran yumbu capacitors tare da ingantacciyar inganci ba, har ma yana ba da kyauta bayan-tallace-tallace.JEC masana'antu sun wuce ISO9001: 2015 ingancin tsarin gudanarwa;JEC aminci capacitors (X capacitors da Y capacitors) da varistors sun wuce takaddun shaida na ƙasashe daban-daban;JEC yumbu capacitors, fim capacitors da super capacitors suna cikin layi tare da ƙananan alamun carbon.
