Txhais: Nws tuaj yeem tso hluav taws xob los yog ob qho tib si fais fab kev khiav hauj lwm overvoltage zog, tiv thaiv cov khoom siv hluav taws xob los ntawm kev siv hluav taws xob dhau los (xws li xob laim overvoltage, kev khiav hauj lwm overvoltage, fais fab zaus zaus overvoltage shock), thiab tuaj yeem txiav tawm freewheeling yam tsis ua rau ib qho khoom siv hluav taws xob uas ua rau luv luv Circuit Court. lub hauv paus system.
Muaj nuj nqi: Thaum lub overvoltage tshwm sim, qhov hluav taws xob ntawm ob lub davhlau ya nyob twg ntawm tus ntes tsis pub tshaj tus nqi teev, kom cov khoom siv hluav taws xob tsis raug puas los ntawm overvoltage;Tom qab siv overvoltage, lub kaw lus tuaj yeem rov qab mus rau lub xeev qub kom ntseeg tau tias lub zog ib txwm muaj ntawm lub cev.
Ntau qhov ntsuas tau koom nrog hauv lub zog ntes
(1) Volt-thib ob yam ntxwv: hais txog kev sib raug zoo ntawm qhov hluav taws xob thiab lub sijhawm.
(2) Lub hwj chim frequency freewheeling: yog hais txog lub hwj chim zaus luv luv-circuit grounding tam sim no ntws los ntawm tom qab hluav taws xob voltage los yog overvoltage tawm xaus, tab sis lub hwj chim zaus voltage tseem ua rau tus ntes.
(3) Kev muaj peev xwm rov qab los ntawm tus kheej ntawm lub zog dielectric: kev sib raug zoo ntawm lub zog dielectric ntawm cov khoom siv hluav taws xob thiab lub sijhawm, uas yog, qhov ceev ntawm rov qab mus rau qhov qub dielectric zog.
(4) Qhov ntsuas hluav taws xob ntawm tus ntes: lub zog loj zaus voltage uas qhov sib txawv tuaj yeem tiv taus tom qab lub hwj chim zaus freewheeling tam sim no hla xoom thawj zaug, thiab yuav tsis ua rau arc rau reignite, tseem hu ua arc voltage.
