Varistor e phetha karolo ea bohlokoa potolohong.Ha overvoltage e etsahala pakeng tsa mekhahlelo e 'meli ea varistor, litšoaneleho tsa varistor li ka sebelisoa ho koala motlakase ho boleng bo tsitsitseng ba motlakase, e le ho hatella motlakase oa potoloho, ho sireletsa potoloho e latelang.
Joale na ua tseba hore na mantsoe ana ke afe: "nominal voltage", "varistor voltage", "residual voltage ratio", "insulation resistance", "leakage current" e bolela'ng bakeng sa li-varistors?Haeba u sa tsebe, bala sehlooho sena ho ithuta.
1. Nominal voltage (V): E boetse e tsejoa e le rated voltage, e bolela boleng ba motlakase ho pholletsa le varistor ha motlakase oa DC oa 1m o feta.
2. Varistor voltage: Boleng ba motlakase bo lekantsoeng lipheletsong tse peli tsa varistor ha motlakase o itseng (1mA DC) o phalla ka har'a varistor.
3. Residual voltage ratio: Ha hona joale ka har'a varistor ke boleng bo itseng, motlakase o hlahisoang lipheletsong tse peli tsa varistor o bitsoa motlakase o setseng oa boleng bona ba hona joale.Residual voltage ratio ke karo-karolelano ea motlakase o setseng ho matla a lebitso.
4. Insulation resistance: khanyetso ea DC ea insulator tlas'a maemo a boletsoeng.Khanyetso ea insulation ea varistor e bolela boleng ba ho hanyetsa pakeng tsa terata e etellang pele (pin) ea varistor le sebaka se sireletsang sa mohanyetsi.
5. Matla a phallo (kA): tlhōrō ea tlhōrō ea hona joale e lumelletsoeng ho feta ka har'a varistor tlas'a nako e behiloeng le palo ea linako, tlas'a ts'ebeliso ea motlakase o tloaelehileng oa hona joale.
6. Leakage current (mA): e bolela ho phalla ha hona joale ka har'a varistor tlas'a mocheso o boletsoeng le tlhōrō ea DC voltage.
Ho utloisisa mantsoe a khethehileng a li-varistors ho ka thusa ha ho tluoa tabeng ea ho khetha li-varistors.Khetha moetsi ea ka tšeptjoang ha u reka li-capacitor tsa ceramic ho ka qoba mathata a mangata a sa hlokahaleng.JYH HSU (kapa Dongguan Zhixu Electronics)ha e na feela mehlala e felletseng ea li-capacitor tsa ceramic tse nang le boleng bo netefalitsoeng, empa hape e fana ka ntle le matšoenyeho kamora ho rekisa.Rea u amohela ho ikopanya le rona haeba u hloka lisebelisoa tsa elektroniki.
