Varistor-ku wuxuu door muhiim ah ka ciyaaraa wareegga.Marka korontadu ay ku dhacdo inta u dhaxaysa labada marxaladood ee varistor-ka, sifooyinka varistor-ka waxaa loo isticmaali karaa in lagu dhejiyo korantada ilaa qiimo go'an, si loo xakameeyo korantada wareegga, iyadoo la ilaalinayo wareegga xiga.
Markaa ma garanaysaa waxa ereyadan: danab magaceedu yahay, danab varistor ah, saamiga korantada hadhaaga, caabbinta dahaarka, awooda hadda, iyo daadinta hadda macnaheedu waa varistors?Haddii aadan aqoon, akhri maqaalkan si aad u barato.
1. Voltaga magacaaban (V): Waxa kale oo loo yaqaan danab la qiimeeyay, waxa loola jeedaa qiimaha danab ee ku dhex jira varistor-ka marka uu hadda DC ah 1m la dhaafo.
2. Varistor Voltage: Qiimaha danabku waxa lagu qiyaasaa labada daraf ee varistor-ka marka qayb gaar ah (1mA DC) uu dhex maro varistor-ka.
3. Residual Voltage ratio: Marka hadda dhex varistor-ku yahay qiime gaar ah, danab ka dhasha labada daraf ee varistor-ka waxaa loo yaqaan danab hadhaaga ah ee qiimahan hadda.Saamiga danabka haraaga ah waa saamiga tamarta haraaga iyo danabka magacaaban.
4. caabbinta dahaarka: caabbinta DC ee dahaarka ee xaaladaha la cayimay.Caabbinta dahaarka ee varistor-ku waxa ay tilmaamaysaa qiimaha iska caabbinta ee u dhexeeya siligga rasaasta (pin) ee varistor-ka iyo dusha dahaadhka caabiyaha.
5. Awood socodka (kA): qiimaha ugu sarreeya ee hadda loo oggol yahay inuu dhex maro varistor-ka hoos yimaada muddada la cayimay iyo tirada wakhtiyada, iyadoo la raacayo codsiga hadda jira ee dareenka caadiga ah.
6. Leakage current (mA): waxa loola jeedaa hadda socda oo dhex socda varistor-ka hoostiisa heerkulka la cayimay iyo korontada ugu sarreysa ee DC.
Fahamka shuruudaha gaarka ah ee varistors ayaa laga yaabaa inay ku caawiyaan marka ay timaado xulashada varistors.Dooro soo saaraha la isku halayn karo marka la iibsanayo capacitors dhoobada waxay ka fogaan kartaa dhib badan oo aan loo baahnayn.JYH HSU (ama Dongguan Zhixu Electronics)ma aha oo kaliya moodooyinka buuxa ee capacitors dhoobada leh tayada dammaanadda leh, laakiin sidoo kale waxay bixisaa iibka ka dib walaac-la'aan.Ku soo dhawoow inaad nala soo xiriirto haddii aad u baahan tahay qalab elektaroonik ah.
