The important power equipment of baoding oil-immersed transformer must be maintained regularly, regardless of whether it is in operation or shutdown. Then, do you know why the oil baoding leaching transformer needs regular maintenance? What are the maintenance contents?
In fact, not only is the baoding oil immersed transformer, for other power equipment, regular maintenance is necessary. This is in order to better guarantee the safe operation of power equipment, regular maintenance, also can timely eliminate hidden dangers, equipment failure found that the problem solves promptly, in order to improve the service life of the transformer.
The regular maintenance contents of baoding oil immersed transformer are as follows:
1. Oil sample test
Transformer oil pressure, the impurities such as performance index once every three years, through the data to judge the existence of oil-immersed transformer overload operation, to know the baoding oil-immersed transformer is running at full capacity or overload for a long time will shorten its life cycle.
2. Test transformer high and low voltage insulation resistance
Its high qualified transformer, low voltage insulation resistance of less than 70% of the original factory value (10 m Ω), winding dc resistance in the same temperature, the difference between the three phase average should not be greater than 2%, compared with the last measurement results should not be greater than 2%. If the data of the detection is very large, it is best to return to the factory for inspection and maintenance, to make more comprehensive inspection, so as to avoid safety hazards.
3. Transformer grounding resistance
The grounding resistance of the oil-immersed transformer is measured every two years. This should not be ignored, because when the grounding resistance is too high or the grounding line breaks down, the power supply will be abnormal and the electrical equipment will be burned, which can be dangerous to the safety of the person.
4. Clean power and check
Baoding oil-immersed transformer after put into use, general need power clean and check every six months to one year time, but its period is different, different transformer according to specific transformer using environment and its load.
The contents of the power failure cleaning and inspection mainly include: clean porcelain casing shell; Replace broken or aging rubber pads; Check the replacement of respirator silicone; Check to tighten connection points, whether oil change is needed, etc.
In conclusion, the regular maintenance of the oil-immersed transformer is necessary for the maintenance of the oil-immersed transformer in the use of oil-immersed transformers.
