In winter, the weather is cold and the air is humid and the temperature is lower. The baoding oil-immersed transformer has certain requirements on the installation and operation ambient temperature. When the ambient temperature drops, the oil level will also drop. If the oil level is lower than the minimum scale of the oil level gauge, the transformer should be refueled in time to avoid faults of the baoding oil-immersed transformer. There are also abnormal phenomena such as oil leakage, too high or too low oil level, abnormal oil temperature, change of oil color, etc. in the operation process of oil-immersed transformer. If the transformer is allowed to continue operation, it may cause the abnormal operation and performance of the transformer, or even cause fault problems, or even cause fire in serious cases. Therefore, the management and maintenance of baoding oil-immersed transformer must be strengthened in winter to ensure the normal operation of oil-immersed transformer.
Key points for winter maintenance and management of oil-immersed transformer:
1. Prevent transformer oil level from being too low
When the transformer runs normally, the oil level rises or falls, which is caused by the temperature change. When the oil level is too low, the aging of transformer oil will be accelerated, and the insulation of transformer will deteriorate, so more inspection, more maintenance, timely oil. If the oil level of the transformer decreases significantly, it may be caused by oil leakage and oil seepage phenomenon of the transformer, which is often caused by the transformer oil tank damage, the oil discharge valve not tightened, the transformer cover not tightened, the oil level gauge damage and other reasons.
2. Observe whether the transformer is leaking oil
If oil leakage is found, the transformer should be handled in time. If oil leakage is serious, the transformer should be stopped in time and repaired.
3. Add transformer oil in time
The weather is cold and the temperature is low in winter. The oil-immersed transformer has certain requirements on the ambient temperature of the installation and operation. When the ambient temperature drops, the oil level will also drop. Therefore, the transformer oil must be added in time.
4. Avoid direct sunlight for transformer oil
Under the action of ultraviolet ray, the oxidation speed of transformer oil is accelerated. Therefore, transformer oil is not allowed to receive direct light. To prevent the transformer oil from being exposed to light, it must be installed in an opaque container.
5. Check the temperature of the oil level thermometer on the top of the tank
When the transformer is in normal operation, the oil temperature in the upper part of the transformer shall not exceed 85 degrees Celsius. If the oil temperature rises suddenly during operation, the transformer is overheating. The causes of this situation are as follows: the external cause is the severe overloading of the transformer; Internal causes include core fire, winding inter-turn short circuit, internal screw loose, cooling device failure, etc.
6. Timely treatment of deteriorated transformer oil
Transformer oil, if often overheat operation or water, moisture absorption, will cause oil quality deterioration. With the deteriorated oil, it is easy for the transformer to have breakdown discharge between the winding and the enclosure, resulting in serious accidents. Therefore, insulation oil must be filtered and recycled. If the transformer oil damp, it should be timely dry.
