1. prevent transformer oil level is too low
When the transformer is in normal operation, the rise or fall of the oil level is caused by the change of the temperature, and the change of the oil level will not be too great. When the oil level drops significantly, even from the oil level gauge invisible level, it may be because the transformer oil leakage, oil leakage phenomenon, it is often because of transformer damage, oil discharge valve does not tighten, the transformer cover does not cover strictly, causes damage to the oil level gauge. Oil level is too low, will accelerate the aging of transformer oil, transformer insulation deterioration, so more visits, more maintenance, timely oil.
2. observe whether the transformer leaks oil
Found that the transformer oil leakage should be dealt with in a timely manner, such as leakage of oil seriously, should promptly stop the transformer, and maintenance. When the inspection, the first to find oil spills, oil spills are relatively easy to find, oil seepage is difficult to find, general dust accumulation and moist place oil seepage. If the transformer oil leaking from the upper end cover, a top ring screw should be tightened; if the transformer oil leaking from the gear, it should open the gear cover, pressing screw inside; if the insulation pad aging, it should be timely replacement of insulating oil pad.
3., one smell, two look, distinguish transformer oil quality
Transformer oil should be subjected to a withstand voltage test for 1~3 years. If the transformer oil does not meet the technical requirements, should be replaced or filtered as soon as possible. Because of the quality of transformer oil is high, without pressure test and the simplified test is very difficult to explain the transformer oil is qualified, but after long-term practice, whether or not qualified by a smell, it seems two differential transformer oil.
One smell: that is, through the smell to identify transformer oil quality, qualified transformer oil should be no smell, or with a little kerosene smell. If there is any other odor, it shows that the oil is bad.
Two see: look at the color of transformer oil. The new transformer oil is usually light yellow, and the color will darken after oxidation. Two look at the transparency of transformer oil. The new transformer oil is transparent in the glass bottle and has a bluish purple fluorescence. If the fluorescence is lost or no longer transparent, the free carbon and mechanical impurities are found in the transformer oil.
