Depth explain how to handle oil leakage from oil immersed transformers under pressure without disassembling or powering off

Oil immersed power transformer have a large market share in the world, but transformer oil leakage is a major problem and hidden danger in the power industry. Hengfengyou electrical engineer reminded that transformer oil leaks occasionally occur. Serious oil leakage will not only shorten the service life of transformers, affect the safe and stable operation of the system, but also affect the effectiveness and availability of power equipment for a long time.

 

 

When oil leaks from the inlet and outlet bushings of an oil immersed transformer, a layer of dirt will accumulate on the bushing. When exposed to moisture, a "dirt flashover" hazard will occur along the outer surface of the bushing of the oil immersed type transformer. Discharge accidents are more likely to occur. Even if you have spare parts for bushings, professionals have to affect the power supply for a day.

 

 

In response to the problem of oil leakage from the high-voltage bushing of a transformer, enterprises generally replace high-quality rubber pads to maintain sealing, and tighten the fixing bolts to prevent leakage of the bushing. Or copper aluminum transition is used for silver copper contacts to reduce oxidation. However, these methods cannot guarantee effectiveness. Based on years of experience in the production of customized transformers, Hengfengyou believes that current carbon nano polymer materials can effectively solve the oil leakage problem. This material technology achieves online and non-stop rapid processing, fully utilizing the comprehensive properties of materials such as oil resistance, high adhesion, and corrosion resistance, achieving rapid plugging of oil spills. Extremely reliable.

 

 

Treatment process for oil leakage of transformer high-voltage bushing:

 

1. Clean the oil stain on the oil leakage part and polish it around the oil leakage part to expose the original color of the metal;

 

2. Clean, the surface should be clean, dry, firm, and rough after treatment;

 

3. Adjust the carbon nano polymer material and seal the leaking part until there is no leakage.

 

4. Seal the rest. After the material has hardened, repair it. Completed.
