Yuav ua li cas Insulation Resistance/Polarization Index Test rau transformer

Rwb thaiv tsev tsis kam thiab polarization Performance index xeem yog cov cuab yeej kuaj xyuas tseem ceeb rau kev txiav txim siab txog qhov xwm txheej ntawm cov rwb thaiv tsev transformer. Cov kev ntsuam xyuas no yog siv los txheeb xyuas txhua yam teeb meem nrog lub rwb thaiv tsev, uas tuaj yeem pab tiv thaiv kev puas tsuaj rau lub cev tsis ua haujlwm thiab txuas ntxiv lub neej ntawm transformer.

Kev ntsuam xyuas ntawm rwb thaiv tsev tsis kam thiab polarization Performance index yuav tsum tau ua raws li

Siv qhov ntsuas hluav taws xob (5KV DC) ntawm qhov txuas hauv qab no thiab nco ntsoov nyeem cov ntawv nyeem

Kev ntsuas kev tiv thaiv rwb thaiv tsev yog ua los ntawm 15 vib nas this mus rau 1 feeb nrog 15 15- lub sijhawm thib ob thiab tom qab ntawd rau txhua feeb txog li kaum feeb. Tus nqi tau txais ntawm 10 feeb muab faib los ntawm tus nqi ntawm 1 feeb muab qhov polarization Performance index

ua cov rwb thaiv tsev tiv thaiv thiab polarization Performance index ntsuas ntawm transformers yog ib qho tseem ceeb ntawm kev tiv thaiv kev txij nkawm. Cov kev ntsuam xyuas no tuaj yeem pab txheeb xyuas txhua yam teeb meem nrog lub rwb thaiv tsev thiab tiv thaiv kev ua tsis tau zoo. Nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov txheej txheem kev nyab xeeb kom raug thaum ua haujlwm nrog cov tshuab hluav taws xob siab, thiab nco ntsoov sab laj tus kws tshaj lij yog tias koj muaj cov dou
