Let’s first look at the consequences of transformer oil leakage:

1. Transformer oil leakage not only seriously affects the appearance, but also causes economic losses because the transformer needs to be shut down to eliminate leakage.

2. Oil leakage will seriously interfere with the operation and maintenance personnel’s monitoring and judgment of the sealing condition in the transformer oil conservator and the correctness of the indication of the oil level gauge.

3. After the oil level is lowered due to leakage, the live connectors and switches may be operated without oil insulation, which may lead to breakdown, short circuit, burnout, and even cause equipment explosion.

4. After the transformer oil leaks, the fully sealed transformer will lose its sealing state, which will easily make the oil-paper insulation suffer from the intrusion of the outside air and moisture, which will reduce the insulation performance, accelerate the aging of the insulation, and affect the safe and reliable operation of the transformer.

How to deal with transformer oil leakage, let’s take a look at the specific treatment measures in combination with the case:

The transformer valve core of a power supply company leaked oil, and most of the valve core valve stem seals failed, resulting in serious oil leakage. Due to the special working environment of the transformer, it was not allowed to stop for a long time, so it could not meet the needs of replacing new parts. The use of Soleil carbon nano-polymer material technology is a more effective way to solve the transformer oil leakage at present.

The operation steps for on-site treatment of transformer oil leakage are as follows:

(1) Clean up the oil stains on the leaking part, and polish around the leaking part to expose the primary metal color;

(2) Clean up, clean, dry, firm and rough after surface treatment;

(3) Reconcile the SD2240 material and seal the leaking parts until there is no leakage;

(4) Reconcile SD7111C material, apply it to SD2240 and metal surface, and completely solve the leakage after the material is cured;

(5) The surface is sprayed with a layer of paint, so that the color is consistent with or similar to the equipment body, and the aesthetics is improved.
