Kev txiav txim siab seb cov roj transformer puas nyob rau hauv qhov tsis zoo yuav tsum ua ntau yam kev ntsuam xyuas los ntsuas nws cov khoom tseem ceeb. Tsis tu ncua
kev ntsuam xyuas yog qhov tseem ceeb rau kev tiv thaiv kev saib xyuas thiab kev tshawb pom ntxov ntawm cov teeb meem tshwm sim. Nov yog qee cov cim qhia tias koj lub transformer
roj tej zaum yuav deteriorating los yog "phem":
Lub zog dielectric: Yog tias lub zog dielectric ntawm cov roj qis dua qhov kev pom zoo, nws qhia txog kev tawg ntawm cov roj.
insulating zog. Lub zog dielectric qis tuaj yeem tshwm sim los ntawm kev kis kab mob, kev laus, lossis lwm yam teeb meem.
Acidity: Qhov nce hauv acidity qhia tias muaj cov kua qaub los ntawm cov khoom hauv cov roj, uas tuaj yeem ua rau cov roj tawg.
nqes dhau lub sijhawm. High acidity tuaj yeem ua kom lub zog degradation ntawm cov ntaub ntawv rwb thaiv tsev nyob rau hauv lub transformer.
Dissolved Gas Analysis (DGA): Cov qib siab ntawm qee cov pa roj xws li methane, ethane, ethylene, thiab acetylene, tuaj yeem ua tau.
qhia txog ntau yam txhaum nyob rau hauv lub transformer, nrog rau overheating, ib nrab paug, los yog arcing.
Moisture Content: Kev nce hauv cov dej noo tuaj yeem cuam tshuam cov dielectric zog ntawm cov roj. Tshaj noo noo tuaj yeem ua rau
los ntawm cov xau los yog kev sib khi tsis raug, thiab nws tuaj yeem ua rau kom muaj kev laus sai thiab txo kev ua haujlwm ntawm rwb thaiv tsev.
Interfacial Tension: Ib qho kev txo qis ntawm kev sib tshuam ntawm lub ntsej muag yuav qhia tau tias muaj cov kab mob sib kis, xws li dej lossis lwm yam.
cov khoom uas tuaj yeem cuam tshuam cov roj lub peev xwm rau insulate.
Xim Hloov: Cov xim hloov tseem ceeb, xws li tsaus nti, yuav qhia tau tias muaj cov kab mob sib kis lossis oxidation.
Oxidation tuaj yeem tshwm sim vim raug huab cua thiab kub siab.
Viscosity: Kev hloov pauv hauv viscosity sab nraum qhov kev teev tseg yuav qhia tau tias muaj kab mob los yog degradation ntawm cov roj.
Particulate Contamination: Ntau theem ntawm cov khoom hauv cov roj tuaj yeem ua rau muaj kev hnav thiab tsim kua muag ntawm lub transformer.
Cheebtsam thiab tej zaum yuav qhia tau hais tias muaj teeb meem xws li rwb thaiv tsev puas los yog mechanical hnav.
Yog tias koj saib ib qho ntawm cov cim qhia no, nws yog ib qho tseem ceeb uas yuav tsum tau ua tib zoo txheeb xyuas cov roj transformer. Kev kuaj roj tsis tu ncua, ua ib feem
ntawm kev saib xyuas, pab txheeb xyuas cov teeb meem tshwm sim thaum ntxov, tso cai rau kev kho kom raug ua ntej
teeb meem loj tshwm sim. Cov chaw soj ntsuam kev tshaj lij tuaj yeem ua tiav kev ntsuas roj transformer, lossis koj tuaj yeem siv
transformer roj kuaj cov khoom siv rau cov kev ntsuam xyuas yooj yim ntawm qhov chaw. Yog tias koj tsis paub meej lossis yog tias cov txiaj ntsig tau qhia txog cov teeb meem tshwm sim, nws yog qhov tsim nyog
mus sab laj nrog tus kws tshaj lij lossis tus kws paub txog kev tu vaj tse transformer rau kev soj ntsuam ntxiv thiab cov lus pom zoo.
