In fact, it is not only to the baoding oil immersed transformer, for other electrical 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 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 error of the test is very large, it is better to return to the factory for inspection and maintenance for more comprehensive inspection, so as to avoid potential safety hazards.

 

3. Transformer grounding resistance.

 

The ground resistance value of the bonded 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, the electrical equipment will be burned, and even the safety of the person will be dangerous.

 

4. Power failure cleaning and inspection.

 

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 power failure cleaning and inspection mainly include: cleaning the shell of porcelain bushing; Replace broken or aged rubber pads; Check the replacement of respirator silicone; Check to tighten connection points, whether oil change is needed, etc.

 

In a word, it is necessary to maintain the regular maintenance of the oil-immersed transformer, which should be used for the maintenance of oil-immersed transformer.
