Qee cov neeg muas zaub, thaum mus xyuas lub Hoobkas, tsa cov lus nug ntawm seb cov khoom siv lub cev muaj zog puas tuaj yeem rov ua dua los ntawm dielectric withstand voltage test. Cov lus nug no kuj tau nug los ntawm ntau tus neeg siv lub cev muaj zog.Dielectric tiv thaiv qhov ntsuas hluav taws xob yog qhov kev kuaj xyuas kom paub qhov kev ua tau zoo ntawm lub tshuab hluav taws xob windings thaum lub sijhawm tsim khoom, nrog rau tag nrho cov khoom siv lub tshuab kuaj. Cov txheej txheem rau kev txiav txim siab kev tsim nyog yog tias cov rwb thaiv tsev tsis tawg raws li cov xwm txheej tshwj xeeb.
Txhawm rau kom ntseeg tau tias lub tshuab hluav taws xob rwb thaiv tsev ua tau raws li qhov yuav tsum tau ua, ntxiv rau kev xaiv cov khoom siv hluav taws xob tsim nyog thiab cov ntaub ntawv insulating, cov txheej txheem txhim khu kev qha kuj tseem tsim nyog. Piv txwv li, kev tiv thaiv thaum lub sij hawm ua, haum fixtures, zoo impregnation khoom, thiab cov txheej txheem tsis tsim nyog.
Noj cov windings ntawm high-voltage motors ua piv txwv, feem ntau lub cev muaj zog manufacturers yuav ua tig-rau-tig thiab dielectric withstand voltage xeem ntawm txhua kauj. Ua ntej impregnation, cov tub ntxhais nrog windings thiab tag nrho lub tshuab thaum lub sij hawm kuaj xyuas yuav undergo dielectric withstand voltage xeem. Qhov no coj peb rov qab rau cov neeg siv khoom tsis ntseeg txog qhov dielectric tiv thaiv qhov teeb meem.
Lub hom phiaj hais lus, dielectric tiv thaiv qhov ntsuas hluav taws xob yog qhov kev sim ua kom tsis muaj kev puas tsuaj. Txawm hais tias nws yog rau windings los yog ib tus neeg coils, nws tsis pom zoo kom ua qhov kev ntsuam xyuas dua, nrog rau qhov tsim nyog ntawm kev nrhiav teeb meem raws li qhov chaw. Nyob rau hauv cov xwm txheej tshwj xeeb uas yuav tsum tau rov kuaj dua, qhov ntsuas hluav taws xob yuav tsum tau txo qis raws li cov txheej txheem tsim nyog kom txo qis kev puas tsuaj rau cov rwb thaiv tsev kom ntau li ntau tau.
Hais txog Dielectric Withstand Voltage Tester
Lub dielectric withstand voltage tester yog ib qho cuab yeej rau ntsuas qhov dielectric withstand voltage zog. Nws muaj peev xwm intuitively, raug, sai, thiab ntseeg siab sim ntau yam hluav taws xob kev nyab xeeb ntsuas kev ua tau zoo xws li cov hluav taws xob tiv taus, tawg voltage, thiab to tam sim no ntawm cov khoom kuaj. Los ntawm dielectric withstand voltage tester, muaj teeb meem tuaj yeem pom thiab ua raws li kev ua haujlwm ntawm rwb thaiv tsev tuaj yeem txiav txim siab.
● Tshawb xyuas lub peev xwm ntawm rwb thaiv tsev tiv thaiv kev ua haujlwm voltage lossis overvoltage.
● Tshawb xyuas qhov zoo ntawm rwb thaiv tsev tsim khoom lossis kev saib xyuas cov khoom siv hluav taws xob.
● Tshem tawm kev puas tsuaj rau cov rwb thaiv tsev los ntawm cov khoom siv raw, kev ua haujlwm, lossis kev thauj mus los, thiab txo qis cov khoom lag luam thaum ntxov.
● Tshawb xyuas kev ua raws li cov hluav taws xob clearance thiab creepage deb ntawm rwb thaiv tsev.
Cov Ntsiab Cai rau Kev Xaiv Dielectric Withstand Voltage Test Voltage
Txoj hauv kev zoo tshaj plaws los txiav txim siab qhov ntsuas hluav taws xob yog teeb tsa raws li cov lus qhia tshwj xeeb uas xav tau rau kev xeem. Feem ntau, qhov ntsuas hluav taws xob tau teeb tsa ntawm 2 npaug ntawm qhov ntsuas hluav taws xob ntxiv rau 1000V. Piv txwv li, yog tias ib yam khoom muaj qhov ntsuas hluav taws xob ntawm 380V, qhov ntsuas hluav taws xob yuav yog 2 x 380 + 1000 = 1760V. Tau kawg, qhov ntsuas hluav taws xob kuj tseem yuav txawv nyob ntawm cov chav kawm rwb thaiv tsev thiab cov khoom sib txawv muaj qhov sib txawv ntawm qhov yuav tsum tau muaj.
Vim li cas nws tseem ceeb heev uas yuav tsum nquag xyuas qhov kev ncaj ncees ntawm qhov ntsuas hluav taws xob?
Dielectric withstand voltage testers ntawm cov kab ntau lawm yog siv ntau zaus, tshwj xeeb tshaj yog cov kev xeem coj thiab kuaj fixtures uas feem ntau nyob rau hauv cov lus tsa suab, ua rau lawv nquag mus rau hauv cov tub ntxhais hlau breakage thiab qhib circuits, uas yog feem ntau tsis yooj yim mus ntes. Yog tias muaj qhov qhib Circuit Court ntawm ib qho chaw hauv lub voj, qhov hluav taws xob siab tawm los ntawm dielectric withstand voltage tester tsis tuaj yeem siv tiag tiag rau cov khoom kuaj. Cov laj thawj no tuaj yeem ua rau lub teeb hluav taws xob siab tsis tuaj yeem siv tiag tiag rau cov khoom sim thaum lub sij hawm dielectric tiv thaiv lub zog ntsuas, thiab ib txwm, tam sim no ntws los ntawm cov khoom kuaj yuav luag xoom. Txij li thaum nws tsis tshaj qhov txwv sab sauv teev los ntawm dielectric withstand voltage tester, qhov ntsuas yuav muab ib qho kev qhia kom paub tseeb tias qhov kev ntsuam xyuas tsim nyog, txiav txim siab qhov rwb thaiv tsev kom tsim nyog. Txawm li cas los xij, cov ntaub ntawv xeem hauv qhov no tsis muaj tseeb. Yog tias cov khoom kuaj tau tshwm sim muaj qhov tsis xws luag hauv lub sijhawm no, nws yuav ua rau muaj kev txiav txim siab loj.
