The winter is cold, the humidity in the air is large, and the temperature is lower. And baoding oil-immersed transformer has certain requirements of installation running environment temperature, when the environment temperature falls, the oil level will decline, if the oil level is below the minimum oil level gage calibration, should be timely to the transformer oil, to avoid baoding oil-immersed transformer fault occurs. And baoding oil-immersed transformer if there is a leak in the process of running, too high or too low oil level, oil temperature is abnormal, the abnormal phenomenon such as color change, if let it continue to run, may be the cause of the transformer can't normal work and performance becomes poor, and even lead to failure, serious when even likely to cause a fire. Therefore, the staff must strengthen the management and maintenance of the oil-immersed transformer in winter to ensure the normal operation of oil-immersed transformer.
Key points of winter maintenance management of baoding oil immersion transformer:
1. Prevent transformer oil level too low
When the oil level rises or falls during normal operation of the transformer, it is caused by the temperature change, and the oil level changes will not be too large. However, when the oil level is too low, the transformer oil will be accelerated and the insulation of the transformer will deteriorate, so we need to inspect more, maintain and add oil in time. If the transformer oil oil level decreased significantly, the oil leakage, oil leakage phenomenon may be because the transformers, this often is because the damage of transformer oil tank, oil drain valve no tight, transformer top cover tightly, damage to the oil level gauge, etc.
2. Observe whether the transformer is leaking oil
It is found that the oil leakage of transformer should be handled in a timely manner. If the oil leakage is serious, the transformer should be stopped and serviced in time.
3. Add transformer oil in time
It's cold and cold in winter. And the oil-immersed transformer has certain requirements for the installation and operating environment temperature. When the ambient temperature decreases, the oil level of the oil-immersed transformer will also decrease, so it is necessary to add transformer oil in time.
4. Avoid direct injection of transformer oil
The oxidation speed of transformer oil is accelerated under the action of ultraviolet ray. Therefore, the transformer oil is not allowed to be exposed to the light. To avoid the light exposure of the transformer oil, it must be installed in an opaque container.
5. Check the temperature of top oil surface thermometer
When the transformer normally runs, its upper oil temperature is no more than 85 degrees Celsius. If the transformer is running, the oil temperature suddenly rises, indicating that the transformer is overheating inside. The reason for this situation is: external cause is the transformer serious overload; Internal reasons include core fire, interwinding short circuit, internal screw loose, cooling device failure, etc.
6. Timely treatment of spoiled transformer oil
The oil will deteriorate if the oil is regularly overheated or in water and moisture absorption. However, it is easy for the transformer to break and discharge between the windings and the shell, causing serious accidents. Therefore, the insulation oil shall be filtered and reprocessed. If the transformer oil is damp, it should be dry in time.
