Vim li cas koj thiaj li yuav tsum ua AC tiv thaiv qhov ntsuas hluav taws xob ntawm cov khoom siv fais fab?AC withstand voltage test yog ib txoj hauv kev zoo thiab ncaj qha los txheeb xyuas lub zog dielectric ntawm cov khoom siv fais fab.
HV Hipot GDTF series Variable Frequency AC resonance Test System
Thaum lub sijhawm ua haujlwm ntawm cov khoom siv fais fab, cov rwb thaiv tsev yuav maj mam deteriorate nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb, kub thiab mechanical vibration rau lub sij hawm ntev.Lub khob roj txheem yog siv rau qhov ntsuas qhov ntsuas hluav taws xob ntawm cov roj insulating los tuav cov roj.Cov no muaj xws li tag nrho deterioration thiab ib nrab deterioration, tsim defects.Piv txwv li, vim lub cheeb tsam hluav taws xob hauv cheeb tsam yog cov concentrated los yog cov rwb thaiv tsev hauv zos tsis muaj zog, muaj qhov tsis xws luag hauv zos.Ntau yam kev ntsuas kev tiv thaiv, txhua tus nrog nws tus kheej lub zog, tuaj yeem pom qee qhov tsis xws luag thiab cuam tshuam txog kev rwb thaiv tsev, tab sis qhov ntsuas hluav taws xob ntawm lwm txoj kev ntsuas feem ntau qis dua qhov ua haujlwm voltage ntawm cov khoom siv hluav taws xob, uas tsis muaj zog txaus raws li kev lees paub rau kev nyab xeeb. kev ua haujlwm..
Txawm hais tias DC tiv taus qhov ntsuas hluav taws xob yog qhov siab, qee cov ntsiab lus tsis muaj zog ntawm cov rwb thaiv tsev tuaj yeem pom, tab sis vim tias feem ntau ntawm cov khoom siv hluav taws xob rwb thaiv tsev yog kev sib xyaw ntawm dielectrics, nyob rau hauv qhov kev txiav txim ntawm DC voltage, qhov voltage yog faib raws li kev tiv thaiv, yog li ntawd. DC yog siv rau kev xeem.Nws tsis yog ib txwm muaj peev xwm nrhiav tau qhov tsis muaj zog ntawm AC cov khoom siv hluav taws xob hauv qab AC hluav taws xob.Piv txwv li, qhov tsis xws luag ntawm lub tshuab hluav taws xob tsis yooj yim pom nyob hauv DC.
AC tiv taus qhov ntsuas hluav taws xob ua tau raws li cov khoom siv hluav taws xob uas cov khoom siv hluav taws xob tau raug rau lub sijhawm ua haujlwm.Nyob rau tib lub sijhawm, AC tiv taus qhov ntsuas qhov ntsuas hluav taws xob feem ntau siab dua qhov kev khiav hauj lwm voltage.Yog li ntawd, tom qab dhau qhov kev xeem, cov cuab yeej muaj qhov loj ntawm kev nyab xeeb, yog li qhov kev sim no tau dhau los ua qhov lav rau kev nyab xeeb.ib qho tseem ceeb ntawm kev ua haujlwm.Txawm li cas los xij, vim tias qhov ntsuas hluav taws xob siv nyob rau hauv AC tiv thaiv qhov ntsuas hluav taws xob ntau dua li qhov kev khiav hauj lwm voltage, qhov hluav taws xob ntau dhau yuav ua rau kom poob ntawm qhov nruab nrab insulating, tsim kom sov, tawm, thiab ua kom muaj kev txhim kho ntawm rwb thaiv tsev tsis xws luag.Yog li ntawd, hauv kev nkag siab, AC tiv thaiv qhov ntsuas hluav taws xob yog qhov kev sim ua kom puas tsuaj.
Ua ntej AC tiv thaiv qhov ntsuas hluav taws xob, ntau yam kev ntsuas uas tsis muaj kev puas tsuaj yuav tsum tau ua ua ntej, xws li ntsuas kev tiv thaiv kev tiv thaiv, kev nqus qhov sib piv, dielectric poob yam tgδ, DC leakage tam sim no, thiab lwm yam. ntaus ntawv yog ntub los yog puas.Yog tias pom tias muaj teeb meem, nws yuav tsum tau kho ua ntej, thiab AC tiv thaiv qhov ntsuas hluav taws xob tuaj yeem ua tiav tom qab tshem tawm qhov tsis xws luag, txhawm rau kom tsis txhob muaj kev puas tsuaj thaum lub sij hawm AC withstand voltage test, nthuav rwb thaiv tsev. tsis xws luag, ncua sij hawm txij nkawm, thiab ua kom cov haujlwm ua haujlwm ntau ntxiv..
