Cov twj siv feem ntau siv los ntsuas cov roj transformer yog cov khoom siv roj transformer. Cov khoom siv no feem ntau suav nrog ntau yam cuab yeej
thiab cov khoom siv los ntsuas qhov xwm txheej ntawm cov roj transformer kom ntseeg tau tias kev ua haujlwm zoo thiab lub neej ntev ntawm transformers.
Qee qhov kev ntsuam xyuas tseem ceeb ua rau cov roj transformer muaj xws li:
Dielectric Strength Test: Qhov kev ntsuam xyuas no ntsuas lub peev xwm ntawm cov roj kom tiv taus hluav taws xob tsis muaj kev tawg. Nws kuj yog
lub npe hu ua breakdown voltage test.
Acidity Test: Qhov kev sim no txiav txim siab acidity ntawm cov roj transformer. Tshaj acidity tuaj yeem qhia tias muaj cov kab mob sib kis lossis
degradation ntawm cov roj.
Interfacial Tension Test: Qhov kev ntsuam xyuas no ntsuas qhov muaj cov kab mob polar contaminants, uas tuaj yeem cuam tshuam rau cov roj insulating zog.
Moisture Content Test: Transformer roj yuav tsum muaj cov ntsiab lus tsis tshua muaj dej kom tswj tau nws cov khoom insulating. Ntau txoj kev,
xws li Karl Fischer titration method, tuaj yeem siv los ntsuas cov dej noo.
Dissolved Gas Analysis (DGA): DGA yog siv los txheeb xyuas thiab txheeb xyuas cov hom thiab cov nqi ntawm cov roj uas yaj hauv lub transformer
roj. Cov roj sib txawv tuaj yeem qhia txog ntau yam txhaum lossis teeb meem hauv lub tshuab hloov pauv.
Xim Xim: Cov xim ntawm cov roj tuaj yeem qhia tias muaj cov kab mob sib kis lossis degradation. ASTM xim nplai feem ntau siv rau
qhov kev xeem no.
Particulate Contamination Test: Qhov kev ntsuam xyuas no ntsuas qhov muaj cov khoom siv los yog cov kab mob sib kis hauv cov roj, uas tuaj yeem cuam tshuam rau lub cev.
rwb thaiv tsev.
Viscosity Test: Lub viscosity ntawm cov roj yog ntsuas los xyuas kom meej tias nws nyob rau hauv qhov kev teev tseg. Kev hloov hauv viscosity tuaj yeem qhia tau
kev kis kab mob los yog degradation.
Transformer roj kuaj yog qhov tseem ceeb rau kev tiv thaiv kev saib xyuas thiab kev tshawb pom ntxov ntawm cov teeb meem muaj peev xwm hauv lub zog hloov hluav taws xob,
pab kom tsis txhob raug nqi khoom siv tsis ua haujlwm thiab lub sijhawm poob. Cov chaw soj ntsuam kev tshaj lij kuj tseem tuaj yeem ua cov kev sim siab dua siv
cov cuab yeej tshwj xeeb.
