Kwicandelo lokukhuselwa kwezixhobo ze-elektroniki, i-varistor licandelo eliphambili kwaye isetyenziswe ngokubanzi kukhuseleko lwe-overvoltige kunye nommiselo we-voltage.Iinguqulelo, zaphawula eyam izimamva ukubonisa izicelo zabo ezahlukeneyo, ezinje ngokusetyenziswa kwekhaya, i-W kummiselo we-vortage, i-G for Quenage, kunye ne-Arc egxothiweyo., kwaye imele ukucima ingxolo.Abavelisi abahlukeneyo banokuba nemithetho yawo yokuthintela, kodwa imigaqo esisiseko kunye neendawo zesicelo ziyafana.
1. UMGAQO-NKQUBO WOKUGQIBELA WOKUGQIBELA
I-vardistor sisixhobo esikhethekileyo se-nonobumba, esigama lingu-voltageNgokungafaniyo nabaqeqeshwa ngokwesintu, ii-faristors azisetyenziswanga ukubonelela ngexabiso lokuphiliswa eliqhubekayo, kodwa njengecandelo lokucinezelwa kwe-voltage.Iimpawu zayo kukuba akukho zibonda zihle kwaye zibi, ezahlukileyo kwenye icandelo lokukhusela eliqhelekileyo leTVs.Kwizicelo ezisebenzayo, ii-disdators zihlala zixhunyiwe kwisekethe ezihlanganisiweyo (i-ICs) okanye iseketheni efuna ukukhuselwa ukuze kufezekiswe ukukhuselwa ngaphezulu kwe-overvoltage.
2. Iimpawu zesicelo se-vardistor
Xa i-voltage isebenza kwi-vartator igqitha kumda wayo omiselwe kwangaphambili, ukumelana kwayo kuya kuncipha ngokukhawuleza, ngaloo ndlela ukuqhuba inkulu yangoku ukukhusela isekethe yokuphela.Ngokuchasene noko, xa i-voltage iphantsi kunevoti yokusebenza, ukuxhathisa kwesanti kuphakama kakhulu, nto leyo elingana norhulumente wesiphaluka, ngenxa yoko ayiyi kuchaphazela ukusebenza kwesiphaluka esingasemva sesekethe.Olu phawu lwenza ukuba ii-farsments zisebenza kakhulu phantsi kwe-gotage fasthlooing kunye neemeko zoqhaqho.
3. Ukusilela kunye nokuthatha amanyathelo omzimba
Nangona izahlulo zingayifumana amandla amakhulu, azinakho ukumelana nemijikelezo emikhulu.Oku kuthetha ukuba lo mqobo weqonga kufuneka uthathele ingqalelo xa uyila i-overvoltity isekethe yokhuseleko.Ngokubanzi, ayilunganga kwimilinganiselo yokuxhasa i-Milliamp yamanqanaba.Ke ngoko, xa usebenzisa i-vardistor, kuyimfuneko ukuba uqonde ngokupheleleyo kwaye uqwalasele imeko yokusebenza yayo kunye namanqanaba akhoyo anokudibana.
Ukuzama ukuphakama, ukwahluka, njengecandelo elisebenzayo lokukhusela ngaphezulu, lidlala indima ebalulekileyo kukhuseleko kunye nokuzinza kwezixhobo ze-elektroniki.Iimpawu zabo ze-nonline kunye nezakhono zokuphendula ezikhawulezayo zibenza babe yinxalenye yoyilo lwesekethe.Nangona kunjalo, abaqulunqi kufuneka kwakhona baqwalasele ukukwazi kwabo okulinganiselweyo kokumelana nokuzinza okwangoku ukuqinisekisa ukhuseleko kunye nokuthembakala kuyo yonke inkqubo ye-elektroniki.Ngokuphuhliswa okuqhubekayo kweetekhnoloji ze-elektroniki, iimfuno zentsebenzo kunye neMihlaba yeZicelo ziya kuqhubeka nokwanda, ukuqhubela phambili inkqubela phambili yeTekhnoloji.
