Transformers ua lub luag haujlwm tseem ceeb hauv kev sib kis thiab kev faib hluav taws xob hluav taws xob. Lawv yog lub luag haujlwm rau kev nce lossis nqis qis qis raws li qhov yuav tsum tau ua kom ntseeg tau tias lub zog tuaj yeem xa mus tau zoo thoob plaws qhov ntev thiab rau cov neeg siv khoom. Txhawm rau kom ntseeg tau tias muaj kev ntseeg siab thiab kev nyab xeeb ntawm cov transformers, niaj hnub ntsuas cov roj transformer yog qhov tseem ceeb.
Transformer roj, tseem hu ua insulating roj los yog roj dielectric, ua hauj lwm raws li ob qho tib si coolant thiab insulator. Nws yog ib qho tseem ceeb rau kev ua haujlwm zoo ntawm lub transformer. Kev ntsuas niaj hnub ntawm cov roj transformer tuaj yeem pab txheeb xyuas cov teeb meem muaj peev xwm ua ntej lawv dhau los ua teeb meem loj uas tuaj yeem ua rau lub tshuab hluav taws xob tsis ua haujlwm.
Muaj ntau qhov kev ntsuam xyuas tseem ceeb uas tau ua ntawm cov roj transformer, suav nrog:
1. Dissolved Gas Analysis (DGA) – DGA yog ib qho kev ntsuam xyuas tseem ceeb uas txheeb xyuas qhov muaj cov roj hluav taws xob uas tsim los ntawm kev ua haujlwm ntawm transformer. Cov pa roj no tuaj yeem qhia tau tias muaj qhov tsis raug lossis lwm yam teeb meem hauv lub tshuab hloov pauv.
2. Cov ntsiab lus noo noo - Cov dej noo tuaj yeem txo qhov zuag qhia tag nrho dielectric lub zog ntawm cov roj transformer, ua rau muaj kev pheej hmoo ntawm arcing thiab muaj peev xwm ua tsis tiav. Kev ntsuam xyuas cov dej noo yog qhov tseem ceeb kom ntseeg tau tias lub tshuab hloov pauv ua haujlwm zoo thiab ntseeg tau.
3. Acid Number - Cov kua qaub ntawm cov roj transformer tuaj yeem qhia tau tias muaj cov tshuaj tiv thaiv corrosive uas tuaj yeem ua rau kev puas tsuaj rau lub transformer, txo nws lub neej tag nrho.
4. Interfacial Tension - Kev txo qis ntawm kev sib tshuam ntawm lub ntsej muag tuaj yeem yog qhov qhia tau tias muaj cov kab mob sib kis hauv cov roj hloov pauv, uas tuaj yeem ua rau muaj teeb meem kev ua haujlwm.
5. Dielectric Breakdown Voltage - Qhov kev ntsuas no ntsuas lub peev xwm ntawm cov roj transformer kom tiv taus hluav taws xob tsis muaj kev tawg. Kev txo qis hauv dielectric breakdown voltage tuaj yeem yog qhov qhia tau tias muaj cov kab mob sib kis lossis lwm yam teeb meem.
6. Roj Tan delta resistivity test-ntsuas dielectric poob yam thiab DC resistivity ntawm kua insulating nruab nrab xws li insulating roj.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias kev sim yuav tsum tau ua nyob rau ib ntus, nyob ntawm lub hnub nyoog thiab qhov xwm txheej ntawm lub transformer thiab hom roj siv. Nws tseem yog ib qho tseem ceeb los xyuas kom meej tias qhov kev ntsuam xyuas yog ua los ntawm cov kws paub txog kev siv cov cuab yeej siv thiab cov txheej txheem tsim nyog. Wuhan Huayi lub tuam txhab hluav taws xob hluav taws xob tshawb fawb thiab tsim cov khoom siv ntsuas roj kom ua tau raws li qhov yuav tsum tau ua, raws li IEC tus qauv. Lawv tuaj yeem kuaj thiab txheeb xyuas qhov tsis sib xws ntawm cov roj transformer thiab tswj kev ua haujlwm ntawm transformers.
