FAQ
Dab tsi yog cov yam ntxwv ntawm varistors?
(1) Kev tiv thaiv cov yam ntxwv, thaum lub zog cuam tshuam ntawm qhov cuam tshuam (lossis qhov cuam tshuam tam sim no Isp = Usp / Zs) tsis tshaj tus nqi teev, qhov txwv qhov hluav taws xob ntawm varistor tsis pub tshaj qhov cuam tshuam nrog voltage (Urp) tias cov khoom tiv thaiv tuaj yeem tiv taus.
(2) Kev cuam tshuam cov yam ntxwv, uas yog, varistor nws tus kheej yuav tsum muaj peev xwm tiv taus qhov cuam tshuam tam sim no, cuam tshuam lub zog, thiab lub zog nruab nrab thaum muaj ntau yam cuam tshuam tshwm sim ib zaug.
(3) Muaj ob lub neej yam ntxwv, ib qho yog lub neej ua haujlwm tsis tu ncua, uas yog, lub varistor yuav tsum tuaj yeem ua haujlwm ruaj khov rau lub sijhawm (teev) raws li qhov ntsuas kub thiab qhov system voltage.Qhov thib ob yog qhov cuam tshuam lub neej, uas yog, tus naj npawb ntawm lub sijhawm nws tuaj yeem tiv taus qhov kev cuam tshuam tshwj xeeb.
(4) Tom qab varistor koom nrog hauv lub cev, ntxiv rau kev tiv thaiv kev ua haujlwm ntawm "kev nyab xeeb valve", nws tseem yuav coj qee qhov cuam tshuam ntxiv, uas yog hu ua "secondary effect", uas yuav tsum tsis txhob txo qhov qub. kev ua haujlwm ntawm qhov system.
