What are the Maintenance Measures of Transformer Oil?

 

What are the Maintenance Measures of Transformer Oil?
Transformer oil plays a role in enhancing insulation, accelerating heat dissipation, antisepsis and arc extinguishing in transformers. Transformer in operation if oil leakage, oil level is too high and too low load, abnormal oil temperature, oil color change is not normal phenomenon, if neglected management, let it continue to operate, may cause power failure, equipment damage, and even cause fire. Therefore, the electrician should strengthen the operation management of the transformer in winter.
1. Prevent Transformer Oil Level is Too Low
The rise or fall of the oil level during the normal operation of the transformer is caused by the temperature change, and the change of the oil level will not be too obvious. When the oil level drops significantly, even can not see the oil level from the oil level gauge, it may because of the transformer oil leakage, oil seepage phenomenon, which often because of the transformer tank damage, the oil discharge valve is not tightened, the transformer cover is not tightly covered, oil level gauge damage and other reasons. Oil level is too low will accelerate the aging of transformer oil, transformer insulation deterioration, so to patrol more, more maintenance, add oil in time.
2. Watch the Transformer for Oil Leakage
If oil leakage of transformer is found, it should be dealt with in time. If oil leakage is serious, the transformer should be stopped and repaired in time. First of all, look for the oil leakage point during the inspection. The oil leakage fault is easy to find, and the oil impregnate is not easy to find. Generally, the dust gathers and the wet place leaks oil. If the transformer oil oozes from the upper end cover, the upper end of a ring of screws should be tightened; If the transformer oil oozes from the gear, you should open the gear cover, tighten the screw inside; When the insulation pad is aging, it should be replaced in time.
3. One Smell and Two Looks to Identify the Quality of Transformer Oil
Transformer oil should be done a voltage test in use for 1-3 years. If the transformer oil cannot meet the technical requirements, it should be replaced or filtered as soon as possible. Due to the high quality requirements of transformer oil, it is difficult to show whether the transformer oil is qualified without voltage test and simplified test, but after long-term practice, whether the transformer oil is qualified or not can be identified by one smell and two looks.
A smell: it is to identify the quality of transformer oil by smelling the odor. The qualified transformer oil should have no odor, or a little coal oil and gas. If there is any other gas, it means that the oil quality has deteriorated.
Two looks: a 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 installed in the glass bottle is transparent, and has a blue purple fluorescence, if lost fluorescence or no longer transparent, indicating that the transformer oil has free carbon and mechanical impurities.
