Tom qab ntau tshaj li kaum xyoo ntawm kev pabcuam, kev rwb thaiv tsev thiab kev ua haujlwm zoo ntawm high{0}}voltageLub tshuab nqus tsev Circuit Court breakersmaj mam deteriorate.
Txawm hais tias lub neej txuas ntxiv tuaj yeem tso cai rau kev pabcuam txuas ntxiv yuav tsum tau txiav txim siab los ntawm kev tshuaj xyuas zoo raws li cov qauv kev lag luam hluav taws xob hauv lub tebchaws thiab cov chaw tsim khoom cov kev qhia tshwj xeeb, siv ntau qhov kev ntsuam xyuas tseem ceeb.
Rwb thaiv tsev kev ua tau zoo thiab lub ntsiab - ntsuas qhov ntsuas hluav taws xob yog cov khoom tseem ceeb. Siv lub siab-voltage meter los ntsuas kev ua haujlwm ntawm rwb thaiv tsev, thiab ib txhij siv lub dielectric poob tester kom tau txais qhov dielectric dissipation yam. Nws yuav tsum tau hais tias qhov nce ntawm dielectric dissipation yam piv rau lub Hoobkas nqi yuav tsum tsis txhob ntau tshaj 30%, thiab tus nqi kiag li yuav tsum tsis txhob ntau tshaj 0.8%, thiaj li yuav xyuas kom meej tias cov rwb thaiv tsev tsis tau cuam tshuam los ntawm noo noo los yog aging.
Kev tiv thaiv ntawm cov hluav taws xob hluav taws xob yog ntsuas los ntawm DC voltage poob txoj kev. Yog tias qhov ntsuas tsis kam tshaj 1.2 npaug ntawm lub Hoobkas tus nqi, nws qhia tias muaj kev sib cuag hnyav, uas yuav tsum tau kho nrog ceev faj.
Kev ua haujlwm kho tshuab thiab theem ob- kev ntsuas hluav taws xob yog qhov tseem ceeb sib npaug. Ua haujlwm qhib thiab kaw ntawm 30% -65% ntawm qhov ntsuas hluav taws xob txhawm rau txheeb xyuas qhov kev ntseeg tau ntawm lub tshuab hauv qab -voltage tej yam kev mob, thiab ntsuas cov neeg kho tshuab mus ncig ceev.
Ib txhij, xyuas cov rwb thaiv tsev ntawm cov hluav taws xob thib ob kom tiv thaiv kev laus ntawm kev tswj cov kab hluav taws xob uas tuaj yeem ua rau tsis zoo lossis tsis ua haujlwm.
AC withstand voltage test ua qhov kev ntsuam xyuas zaum kawg: siv 80% ntawm lub Hoobkas ntsuas hluav taws xob rau ib feeb los txheeb xyuas tag nrho cov txheej txheem rwb thaiv tsev.
Tsuas yog tom qab tag nrho tsib qhov kev xeem dhau los ua tauLub tshuab nqus tsev Circuit Court breakertau txais kev pom zoo rau kev pabcuam txuas ntxiv, tab sis lub sijhawm txuas ntxiv yuav tsum tsis pub tshaj 5 xyoos. Qhov kev txiav txim siab ntawm kev ncua lub neej tsis yog kev so ntawm lub hnub nyoog txwv; nws yuav tsum yog raws li cov ntaub ntawv xeem.
Tsuas yog thaum muaj kev pheej hmoo raug tswj tau tuaj yeem siv txuas ntxiv yog qhov tseeb - qhov no yog lub luag haujlwm tiag tiag ntawm ob qho khoom siv thiab daim phiaj hluav taws xob.
