When the oil level drops significantly or even the level of the oil level can not be seen, it may be caused by the leakage and oil leakage of the transformer, which is often caused by the damage of the transformer tank, the non tightening of the oil discharge valve, the lack of the cover of the transformer top, the damage of the oil level meter and so on. The low oil level will accelerate the aging of transformer oil and the deterioration of transformer insulation. So we need to patrol more, maintain more and add oil in time.
Transformer oil plays an important role in enhancing insulation, accelerating heat dissipation, corrosion protection and arc extinguishing in transformer. If oil leakage, high oil level or low oil level, abnormal oil temperature and change of oil color are abnormal in the operation of transformer, it may cause power failure, equipment damage and even fire if it is neglected to manage and keep it running. Therefore, electricians should strengthen operation management of transformers in winter.
It is found that the leakage of transformer must be dealt with promptly, such as serious leakage of oil, so the transformer should be stopped and repaired in time. First of all, we should look for the oil leakage point. It is easy to find the oil leakage fault. Oil leakage is not easy to find.
If the transformer oil is exuded from the upper cover, a screw should be fastened at the upper end. If the transformer oil is exuded from the gear position, it should open the retaining cover and tighten the pressure screw in the inside. If the insulation pad is aging, the insulating oil pad should be replaced in time.
Transformer oil should be subjected to a voltage withstand test for 1~3 years. If transformer oil is not up to the technical requirements, it should be replaced or filtered as early as possible. Because the quality of transformer oil is very high, it is difficult to explain whether transformer oil is qualified without pressure test and simplified test. But after long-term practice, the qualification of transformer oil can be identified by one smell and two.
