Thaum mus xyuas lub Hoobkas, qee tus neeg siv khoom nug seb cov khoom siv lub cev muaj zog puas tuaj yeem raug kuaj xyuas qhov hluav taws xob dielectric ntau zaus. Cov lus nug no kuj tau raug nug los ntawm ntau tus neeg siv lub cev muaj zog. Kev kuaj xyuas qhov hluav taws xob dielectric yog kev kuaj pom kev ua haujlwm rwb thaiv tsev ntawm cov xov hlau lub cev muaj zog thaum lub sijhawm ua ntau lawm, nrog rau kev kuaj xyuas tag nrho cov khoom siv tshuab. Cov qauv rau kev txiav txim siab txog kev tsim nyog yog tias cov rwb thaiv tsev tsis raug rhuav tshem raws li cov xwm txheej tshwj xeeb.
Yuav kom ntseeg tau tias qhov kev ua haujlwm rwb thaiv tsev ntawm lub cev muaj zog ua tau raws li qhov yuav tsum tau ua, ntxiv rau kev xaiv cov xov hlau hluav taws xob thiab cov ntaub ntawv rwb thaiv tsev uas tsim nyog, kev lav phib xaub txhim khu kev qha kuj tseem ceeb heev. Piv txwv li, kev tiv thaiv thaum lub sijhawm ua haujlwm, cov khoom siv tsim nyog, cov khoom siv impregnation zoo, thiab cov txheej txheem tsim nyog.
Piv txwv li, piv txwv li, feem ntau cov tuam txhab tsim khoom siv lub cev muaj zog yuav ua qhov kev sim hluav taws xob ntawm txhua lub kauj thiab dielectric. Ua ntej impregnation, lub hauv paus nrog cov windings thiab tag nrho lub tshuab thaum lub sijhawm kuaj xyuas yuav dhau los ntawm kev sim hluav taws xob dielectric. Qhov no coj peb rov qab mus rau cov neeg siv khoom tsis ntseeg txog qhov teeb meem dielectric.
Hais lus tseeb, kev sim dielectric withstand voltage yog ib qho kev sim uas tsis tuaj yeem rov ua dua. Txawm hais tias nws yog rau cov windings lossis cov kauj ib leeg, nws tsis pom zoo kom ua qhov kev sim rov ua dua, nrog rau qhov tsim nyog ntawm kev nrhiav teeb meem ua lub hauv paus. Hauv cov xwm txheej tshwj xeeb uas xav tau kev sim rov ua dua, qhov voltage kuaj yuav tsum raug txo raws li cov qauv kev cai kom txo qis kev puas tsuaj rau cov rwb thaiv tsev ntau li ntau tau.
Txog Dielectric Withstand Voltage Tester
Lub dielectric withstand voltage tester yog ib qho cuab yeej siv los ntsuas lub zog dielectric withstand voltage. Nws tuaj yeem sim ntau yam kev nyab xeeb hluav taws xob xws li lub zog withstand, lub zog tawg, thiab tam sim no ntawm cov khoom sim tau yooj yim, raug, sai, thiab ntseeg tau. Los ntawm lub dielectric withstand voltage tester, teeb meem tuaj yeem pom thiab ua raws li kev ua haujlwm rwb thaiv tsev tuaj yeem txiav txim siab.
● Tshawb nrhiav lub peev xwm ntawm cov rwb thaiv tsev kom tiv taus qhov hluav taws xob ua haujlwm lossis overvoltage.
● Tshawb xyuas qhov zoo ntawm kev tsim khoom rwb thaiv tsev lossis kev saib xyuas cov khoom siv hluav taws xob.
● Tshem tawm kev puas tsuaj rau cov khoom rwb thaiv tsev uas tshwm sim los ntawm cov khoom siv raw, kev ua tiav, lossis kev thauj mus los, thiab txo qhov kev ua tsis tiav ntxov ntawm cov khoom.
● Tshawb xyuas seb qhov sib npaug ntawm qhov hluav taws xob thiab qhov deb ntawm cov khoom rwb thaiv tsev puas sib npaug.
Cov Ntsiab Cai rau Kev Xaiv Dielectric Withstand Voltage Test Voltage
Txoj kev zoo tshaj plaws los txiav txim siab qhov hluav taws xob kuaj yog teeb tsa raws li cov lus qhia uas xav tau rau kev sim. Feem ntau, qhov hluav taws xob kuaj yog teeb tsa ntawm 2 zaug ntawm qhov hluav taws xob ntsuas ntxiv rau 1000V. Piv txwv li, yog tias cov khoom muaj qhov hluav taws xob ntsuas ntawm 380V, qhov hluav taws xob kuaj yuav yog 2 x 380 + 1000 = 1760V. Tau kawg, qhov hluav taws xob kuaj kuj tseem yuav txawv nyob ntawm chav kawm rwb thaiv tsev thiab cov khoom sib txawv muaj qhov xav tau hluav taws xob sib txawv.
Vim li cas nws thiaj li tseem ceeb uas yuav tsum tau kuaj xyuas qhov kev ua tiav ntawm lub voj voog kuaj xyuas tas li?
Cov cuab yeej ntsuas hluav taws xob dielectric ntawm cov kab ntau lawm siv ntau zaus, tshwj xeeb tshaj yog cov hlau ua los ntawm kev sim thiab cov khoom siv sim uas feem ntau txav mus los, ua rau lawv yooj yim tawg ntawm cov hlau sab hauv thiab qhib cov voj voog, uas feem ntau tsis yooj yim nrhiav tau. Yog tias muaj lub voj voog qhib ntawm txhua qhov chaw hauv lub voj voog, qhov tso zis hluav taws xob siab los ntawm lub cuab yeej ntsuas hluav taws xob dielectric tsis tuaj yeem siv rau cov khoom sim. Cov laj thawj no tuaj yeem ua rau qhov teeb tsa hluav taws xob siab tsis tuaj yeem siv rau cov khoom sim thaum lub sijhawm ntsuas lub zog dielectric, thiab ntawm chav kawm, tam sim no ntws los ntawm cov khoom sim yuav luag xoom. Vim tias nws tsis tshaj qhov txwv siab tshaj plaws uas lub cuab yeej ntsuas hluav taws xob dielectric teeb tsa, lub cuab yeej yuav muab qhov kev ceeb toom tias qhov kev sim tau tsim nyog, xav txog qhov rwb thaiv tsev kom tsim nyog. Txawm li cas los xij, cov ntaub ntawv sim hauv qhov no tsis yog qhov tseeb. Yog tias cov khoom sim muaj qhov tsis zoo ntawm rwb thaiv tsev lub sijhawm no, nws yuav ua rau muaj kev txiav txim siab tsis zoo.
