Baoding oil-immersed transformer in daily use, it is inevitable to encounter this or that kind of problems, oil leakage phenomenon is very common. Once the oil leakage of oil-immersed transformer will directly affect the normal use of transformer, so, in this case, it is very important to find out the cause of oil leakage of baoding oil-immersed transformer and solve it. Next, we will take a look at shandong tva power equipment co., ltd. on transformer leakage causes of several analysis.

The leakage reasons of baoding oil-immersed transformer mainly include:

1, rubber seals failure and weld cracking.

Because the welding point of transformer is very much, weld shop, the way that appears leakage in daily use is more also, the reason of direct leakage may be the failure of rubber seal and weld crack, porosity, slag inclusion and so on.

2. Poor manufacturing quality of transformers.

In the process of transformer manufacturing, many welding spots in the oil tank, welding factories, welding difficulties, welding materials, welding specifications, process, technology and so on will affect the quality of welding, resulting in gas holes, sand holes, virtual welding, de-welding and other transformer leakage oil phenomenon.

3, sealant aging, cracking deformation.

Transformer leakage occurs in the connection, and more than 95% is mainly caused by sealant. The quality of sealant mainly depends on its oil resistance performance, oil resistance performance is poor, the aging speed is faster, especially at high temperature, its aging speed is faster, easily cause the sealing part aging, cracking, deterioration, deformation, and failure, resulting in transformer leakage oil.

4. Improper installation method.

If the transformer flange connection is uneven, when installing the gasket around the force is not uniform, artificially caused around the gasket bolt non-uniform force, flange joint deformation dislocation, will make the gasket side of the force is too large, side of the force is too small, the force is too small on one side of the gasket due to insufficient compression is easy to cause leakage.

To sum up, baoding oil immersed transformer leakage is nothing more than the above several reasons, if everyone in the daily use of oil leakage, may as well in view of the above several situations for one by one investigation, in order to ensure that as soon as possible to deal with the oil immersed transformer leakage baoding, as far as possible to reduce the loss.
