Analysis of the reasons for the high oil level of special transformers

Reasons for high oil level:

1. The change of the temperature of the special transformer can change the oil level. With the change of the oil temperature, the oil level will also change in a certain range. However, under abnormal circumstances, due to oil leakage, water leakage and other faults and other accidents will also occur. cause abnormal changes in oil level;

2. The change of oil temperature is related to load conditions, ambient temperature and other conditions. When the oil level change is inconsistent with these factors, it may be a false oil level. The reasons for the false oil level: a. The oil standard pipe is blocked; b. Explosion-proof Pipe vents are blocked;

3. If the oil level is too high, an oil spill will be formed.

Solutions and emergency measures:

1. If there is gas relay protection, the trip circuit will be exempted to avoid false tripping;

2. The operator on duty should always check the indication of the oil level gauge, and if the oil level is too high, they can drain the oil in an appropriate amount;

3. When abnormal oil injection is found in the oil pillow or explosion-proof pipe, the power supply of the special transformer should be cut off in time to avoid the expansion of faults and accidents.

If the oil level of the special transformer is too high, we must find a way to reduce it. If the oil level is too high, it is easy to cause the equipment to overheat, which will affect its work. If the situation is serious, it is likely to burst. We must treat this matter carefully. .
