CT thiab PT xa mus rau tam sim no Transformers thiab Muaj Peev Xwm Transformers, feem. Cov no yog cov cuab yeej cuab tam siv hauv lub tshuab hluav taws xob los ntsuas thiab saib xyuas cov hluav taws xob tam sim no thiab qhov hluav taws xob kom raug. Kev kuaj CT thiab PT suav nrog ntau cov txheej txheem los xyuas kom meej qhov ua haujlwm zoo thiab raug ntawm cov hloov pauv no. Nov yog cov ntsiab lus luv luv ntawm CT thiab PT kuaj:
Tam sim no Transformer (CT) Testing:
Ratio Test:
Lub hom phiaj tseem ceeb ntawm CT yog los hloov cov tam sim no siab hauv thawj lub voj voog mus rau qhov sib npaug qis dua tam sim no hauv theem nrab. Qhov kev ntsuam xyuas piv qhia tias qhov sib piv ntawm cov thawj thiab theem nrab windings yog nyob rau hauv cov kev txwv.
Polarity Test:
CTs muaj qhov tshwj xeeb polarity, qhia txog cov kev taw qhia ntawm cov dej ntws tam sim no. Qhov kev ntsuam xyuas polarity ua kom ntseeg tau tias cov kev taw qhia tam sim no tau txais los ntawm CT sib tw rau cov lus qhia.
Excitation Test:
Qhov kev ntsuam xyuas excitation xyuas CT qhov kev ua tau zoo nyob rau hauv ntau theem ntawm thawj tam sim no. Nws ua kom ntseeg tau tias CT muab qhov tseeb thib ob tam sim no dhau ntawm nws qhov kev teev tseg ntawm qhov tseem ceeb tam sim no.
Rwb thaiv tsev Resistance Test:
Qhov kev ntsuam xyuas no ntsuas cov rwb thaiv tsev tiv thaiv ntawm CT windings thiab transformer lub hauv paus. Nws pab txheeb xyuas cov rwb thaiv tsev puas lossis degradation.
Saturation Test:
Kev ntsuam xyuas saturation yog ua los txiav txim siab qhov chaw uas CT core ua saturated. Saturation cuam tshuam qhov tseeb ntawm kev ntsuas tam sim no, thiab qhov kev sim no ua kom ntseeg tau tias CT ua haujlwm nyob rau hauv nws cov kab tawm.
Muaj peev xwm Transformer (PT) Test:
Ratio Test:
Zoo ib yam li CTs, PTs tau txais qhov kev ntsuas piv kom paub meej tias qhov kev hloov pauv ntawm cov thawj thiab theem nrab windings yog nyob rau hauv cov kev txwv. PTs nqis nqis siab mus rau theem tsim nyog rau kev ntsuas thiab kev tiv thaiv cov cuab yeej.
Polarity Test:
PTs kuj muaj ib qho polarity, qhia txog cov kev taw qhia ntawm qhov hluav taws xob. Qhov kev ntsuam xyuas polarity ua kom ntseeg tau tias PT cov zis voltage yog nyob rau hauv qhov tseeb theem kev sib raug zoo nrog cov thawj voltage.
Excitation Test:
Qhov kev xeem excitation rau PTs ntsuas lawv qhov kev ua tau zoo ntawm ntau theem ntawm thawj qhov hluav taws xob. Nws ua kom ntseeg tau tias PT muab qhov tseeb thib ob qhov hluav taws xob tshaj nws qhov kev teev tseg ntawm qhov tseem ceeb ntawm qhov tseem ceeb.
Rwb thaiv tsev Resistance Test:
Zoo ib yam li CTs, PTs tau txais kev ntsuas kev tiv thaiv hluav taws xob los xyuas seb puas muaj kev puas tsuaj los yog kev puas tsuaj.
Dielectric zog Test:
Qhov kev sim no suav nrog kev siv hluav taws xob ntau dua li qub rau PT kom ntseeg tau tias nws cov rwb thaiv tsev tuaj yeem tiv taus qhov hluav taws xob tsis muaj kev puas tsuaj.
Ob qho tib si CT thiab PT xeem yog qhov tseem ceeb los tswj qhov raug thiab kev ntseeg siab ntawm cov cuab yeej hloov pauv hauv cov tshuab hluav taws xob. Kev ntsuam xyuas tsis tu ncua pab txheeb xyuas cov teeb meem muaj peev xwm, ua kom muaj kev ua raws li cov qauv, thiab ua rau muaj kev nyab xeeb tag nrho thiab kev ua haujlwm ntawm cov khoom siv hluav taws xob. Kev ntsuam xyuas feem ntau yog ua thaum lub sijhawm ua haujlwm, kev saib xyuas niaj hnub, thiab teb rau txhua qhov kev xav tsis raug lossis teeb meem kev ua haujlwm.
