Kev tswj xyuas cov roj kom zoo hauv lub tshuab hloov pauv yog qhov tseem ceeb rau nws txoj haujlwm zoo thiab kev nyab xeeb. Yog hais tias lub transformer roj theem qis,
Muaj ntau qhov tsis zoo yuav tshwm sim, uas ua rau muaj teeb meem loj:
Txo Txias Muaj Peev Xwm: Cov roj hloov pauv ua lub tshuab ua kom txias rau lub tshuab hloov pauv, dissipating cua sov tsim thaum lub sijhawm ib txwm muaj
kev ua haujlwm. Yog hais tias cov roj theem qis, lub peev xwm txias yuav raug cuam tshuam, ua rau kom siab kub hauv lub transformer.
Overheating tuaj yeem ua kom cov ntaub ntawv rwb thaiv tsev laus zuj zus, txo qhov hloov pauv lub neej, thiab tuaj yeem ua rau rwb thaiv tsev.
kev tawg.
Txo Dielectric zog: Transformer roj muab hluav taws xob rwb thaiv tsev ntawm transformer windings thiab lwm yam
cov khoom siv sab hauv. Cov roj tsis txaus tuaj yeem ua rau lub zog dielectric poob qis, ua rau lub tshuab hloov pauv tau yooj yim dua
rau hluav taws xob tawg, arcing, thiab lwm yam hluav taws xob faults.
Muaj kev pheej hmoo ntawm Arcing thiab Hluav Taws Kub: Cov roj tsawg tuaj yeem nthuav tawm cov khoom sab hauv rau saum huab cua, ua rau muaj kev pheej hmoo ntawm arcing thiab
taws. Qhov no tuaj yeem ua rau kev txhim kho ntawm qhov kub thiab txias, rwb thaiv tsev tsis ua haujlwm, thiab, nyob rau hauv qhov xwm txheej hnyav, muaj peev xwm ntawm lub tshuab hloov pauv.
hluav taws.
Corrosion thiab Oxidation: Thaum cov roj qib qis, cov khoom uas feem ntau submerged hauv cov roj yuav raug rau huab cua, ua rau
rau corrosion thiab oxidation. Qhov no tuaj yeem degrade cov xwm txheej ntawm cov khoom siv sab hauv, txo qhov kev ntseeg siab ntawm lub transformer.
Kev pheej hmoo ntawm kev kis kab mob: cov roj tsawg ua rau muaj kev pheej hmoo ntawm cov kab mob sab nraud, xws li plua plav, dej noo, thiab cov khib nyiab, nkag mus rau hauv
transformer. Cov khoom paug tuaj yeem cuam tshuam cov khoom dielectric ntawm cov roj thiab ua rau muaj kev puas tsuaj rau cov rwb thaiv tsev.
Mechanical Stress: Cov qib roj tsim nyog pab txhawb kev sib raug zoo ntawm lub tshuab hluav taws xob, muab kev txhawb nqa rau lub zog.
windings thiab lwm yam khoom. Cov roj tsawg tsawg tuaj yeem ua rau cov khoom siv hluav taws xob hloov pauv mus rau kev ntxhov siab ntxiv,
tej zaum yuav ua rau mechanical tsis ua hauj lwm.
Txhawm rau daws cov teeb meem no, nws yog ib qho tseem ceeb uas yuav tsum tau saib xyuas thiab tswj cov qib roj transformer. Yog pom cov roj theem
qis, nws yog ib qho tseem ceeb los soj ntsuam thiab kho qhov ua rau ntawm qhov qis. Qhov no yuav suav nrog kev txheeb xyuas thiab kho cov xau,
Hloov cov khoom puas lawm, thiab rov ua cov roj ntxiv mus rau qib pom zoo.
Kev tu txhua lub sijhawm hloov pauv, suav nrog kev kuaj xyuas roj raws sijhawm, ua kom lub tshuab hloov pauv ua haujlwm nyob rau hauv qhov tsis muaj kev nyab xeeb
thiab pab tiv thaiv tej teeb meem uas yuav ua rau raug nqi kho mob los yog downtime. Yog tias koj xav tias muaj teeb meem nrog lub transformer
roj theem, nws yog advisable mus sab laj nrog ib tug tsim nyog transformer txij nkawm tus kws tshaj lij los ntsuam xyuas qhov teeb meem thiab coj
kev kho kom raug.
