Oil change and boring treatment of power transformer

In the operation of Power Transformers, it is necessary to pay attention to the protection and maintenance of transformers. In the same way, the power transformer also has a lot of attention when it is on hold. The power transformer is left for too long, the operation time is too long or other natural human factors affect the formation of power transformer insulation, internal water or oil quality deterioration. At this time, the power transformer must be changed and processed.

First, the power transformer oil change
Lift the body first, drain the oil and wash the fuel tank. If there is oil on the body, it should be washed away. After the body is dried, inject new oil and replace all oil-resistant rubber seals. After the experiment is passed, the network can be operated.
Second, the power transformer boring treatment
There are many ways to dry the body. When the user self-baking, the zero phase sequence drying method, the eddy current drying method, the short circuit drying method, the oven drying method, and the like can be used. For power transformers with a large capacity and a voltage of 35 kV, it is best to send them to the manufacturer for vacuum drying. This can ensure that the power transformer insulation is boring completely without aging the insulation.
