Basic Principple of Withstand Voltage Tester

Kev ntsuas hluav taws xob tiv thaiv yog hais txog qhov kev sim ntawm qhov muaj peev xwm tiv taus hluav taws xob ntawm ntau yam khoom siv hluav taws xob, cov ntaub ntawv insulating thiab cov qauv insulating. Cov txheej txheem ntawm kev siv hluav taws xob siab rau cov khoom siv insulating lossis cov qauv insulating yam tsis muaj kev puas tsuaj ntawm cov khoom siv insulating yog hu ua kev ntsuas hluav taws xob tiv thaiv. Feem ntau hais lus, lub hom phiaj tseem ceeb ntawm kev ntsuas qhov ntsuas hluav taws xob yog txhawm rau txheeb xyuas lub peev xwm ntawm cov rwb thaiv tsev kom tiv taus kev ua haujlwm voltage lossis overvoltage, thiab tom qab ntawd xyuas seb qhov kev ua tau zoo ntawm cov khoom siv hluav taws xob puas ua tau raws li cov qauv kev nyab xeeb.
Lub hauv paus ntsiab lus ntawm kev ntsuas qhov ntsuas hluav taws xob: qhov hluav taws xob siab dua li qhov ua haujlwm ib txwm siv hluav taws xob yog siv rau lub rwb thaiv tsev ntawm cov cuab yeej hauv kev sim, thiab kav rau lub sijhawm teev tseg. Yog tias qhov rwb thaiv tsev ntawm lawv zoo txaus, qhov hluav taws xob siv rau nws tsuas yog tsim cov xau me me tam sim no. Yog hais tias qhov hluav taws xob tam sim no ntawm lub rwb thaiv tsev ntawm cov cuab yeej nyob rau hauv kev sim nyob rau hauv qhov kev teev tseg nyob rau hauv ib lub sij hawm, nws yuav txiav txim tau hais tias cov cuab yeej nyob rau hauv kev ntsuam xyuas yuav ua hauj lwm yam xyuam xim nyob rau hauv ib txwm ua hauj lwm tej yam kev mob. Thaum ua tiav qhov kev ntsuas hluav taws xob tiv thaiv, cov kev qhia tshwj xeeb ntawm cov khoom kuaj tau sib txawv, thiab cov qauv ntsuas kuj sib txawv. Rau cov khoom siv kuaj dav dav, qhov ntsuas qhov ntsuas hluav taws xob yog ntsuas qhov xau tam sim no tus nqi ntawm cov hlau nyob thiab cov casing. Txoj cai yooj yim yog: ob zaug ntawm qhov ua haujlwm voltage ntawm cov khoom kuaj ntxiv rau 1000V yog siv raws li tus qauv voltage ntawm kev xeem. Qhov ntsuas hluav taws xob ntawm qee cov khoom yuav siab dua li tus nqi teev tseg. Raws li cov kev cai ntawm IEC61010, qhov ntsuas hluav taws xob yuav tsum maj mam nce mus rau qhov ntsuas qhov ntsuas qhov ntsuas qhov xav tau (xws li 5kV, thiab lwm yam) tsis pub dhau 5s, thiab xyuas kom meej tias qhov ntsuas qhov ntsuas hluav taws xob ruaj khov siv rau lub ntsuas hluav taws xob hauv kev sim tsis pub tsawg tshaj 5s. . Muab piv rau tus nqi tam sim no nrog rau qhov hluav taws xob qhov hluav taws xob tam sim no tau teev tseg hauv tus qauv, nws tuaj yeem txiav txim siab seb qhov rwb thaiv tsev ntawm cov khoom kuaj tau raws li tus qauv. Tom qab qhov kev xeem, qhov ntsuas hluav taws xob yuav tsum tau maj mam txo mus rau xoom hauv lub sijhawm teev tseg.
