Transformer oil leakage problems and plugging method—Wulun
Visit: 2758     Date: 2016-04-16


The reason of the leakage with two main aspects:

First,left over in the transformer design and manufacturing process; on the other hand is due to improper installation and maintenance of the transformer cause leakage. The main parts of the transformer leakage often occurs at the interface radiator, flat disc valve cap sleeve, porcelain, weld, trachoma, flanges and other parts.


Jiangshan Wulun International Co.,Ltd.developed a new polymer alloy compatibility between water and oil is mixed with silicon alloy-based macromolecular polymer reaction, the surface of the water and oil can be strongly bonded to the surface of the hand-simple handling, high frequency transformer oil can be effectively sealed. Mainly for leakage transformer leakage steam turbine, generator leaking oil, gear oil leakage treatment, you can not stop, no relief, case and hold the oil can be quickly and efficiently resolved. Since the material itself has good aging resistance, can ensure long-term effective governance.



Transformer leakage mainly in the following areas: the total leakage points more than 50% of the site is the radiator interface flat disc valve cap, radiator bulkhead, connecting flange seal; 16% casing, insulator leakage; 12% gas leakage relay interface. The other is the transformer manufacturing defect existing in the process, such as welding, trachoma and so on.


1.welding oil leakage Governance:
The formation of the problem:
Mainly the poor quality of welding, the presence of Weld, Desoldering, weld exist, trachoma and other defects, the transformer flux due to the factory and paint coverage will be exposed after running risks, in addition to the electromagnetic vibration causes vibration welding crack, resulting in leakage.

way of solving the problem:
For leakage phenomenon has emerged, first identify leakage points, can not be missed. Need to be constantly cleaned, traces of oil along to find out the source of leakage, the use of water-oil supplements compatibility of the leak is sealed, you can achieve the purpose of long-term governance leakage after curing.

2.cast iron oil leakage
Problems Causes:
The main reason is oil leakage iron castings and cracks caused by trachoma.
way of solving the problem:
For crack leakage, drill hole is to eliminate stress only way to avoid extension. Governance under the circumstances, when cracks in the lead wire into the drain point or hand hammer riveting die. Then clean the leakage points, tonic water and oil compatibility titanium steel rubber seal.
