2.Definition ntawm roj-immersed hwj chim transformer overhaul
- Transformer overhaul - yog hais txog kev ua haujlwm ntawm dismantling thiab overhauling cov pab pawg tseem ceeb thiab cov khoom ntawm lub cev transformer kom ntws cov roj, dai npog (dai core) lossis nkag mus rau hauv lub tank roj hauv lub xeev ntawm lub zog tsis ua haujlwm.
- Kev kho me me ntawm transformer - yog hais txog kev saib xyuas ntawm lub thawv transformer, pab pawg thiab cov khoom hauv lub xeev ntawm lub zog tsis ua haujlwm.
- Kev kho tsis zoo ntawm transformer - yog hais txog lub hom phiaj hauv zos overhaul ntawm transformer lub cev, pawg thiab cov khoom.
- Kev tshuaj xyuas niaj hnub thiab kev saib xyuas ntawm transformer - yog hais txog kev tu lub sij hawm, ntsia liaj qhov rooj nruj, kev kho mob, thiab kev hloov pauv ntawm qhov hnav ntawm lub cev transformer, pawg thiab cov khoom.
- Kev kuaj mob - txhawm rau txhawm rau ntsuas lub xeev ntawm cov cuab yeej siv ntxiv, qhov kev sim ua tiav rau cov khoom siv tsis raug.
- 2.Qhov tseem ceeb thiab qhov tsim nyog ntawm kev hloov kho tsis tu ncua thiab kev saib xyuas cov roj-immersed transformers
Fais fab transformers yog nyob rau hauv ib tug tseem ceeb heev txoj hauj lwm nyob rau hauv lub hwj chim system, thiab theem ntawm kev khiav hauj lwm, overhaul thiab txij nkawm thiab seb lawv tau ua tsis tu ncua thiab irregularly raws li cov kev cai yog ncaj qha cuam tshuam rau kev ruaj ntseg, kev cia siab thiab kev khwv nyiaj txiag ntawm lub hwj chim mov.
