Transformer oil dehydration treatment solution

Transformer oil is an indispensable component of the power system, but the moisture that may be contained in the oil can affect its insulation performance and heat dissipation effect, potentially causing equipment failure. Therefore, it is very important to dehydrate the transformer oil.

Vacuum oil filter dehydration method

The vacuum oil filter is a highly efficient piece of equipment for dehydrating transformer oil. Its working principle is to remove moisture and gas from the transformer oil by using low-temperature evaporation and condensation recovery technology under a vacuum state. The specific steps are as follows:

1. Heat the transformer oil to a certain temperature to reduce the viscosity of the oil and increase the evaporation rate of moisture.

2. Extract the air and moisture in the oil through a vacuum pump to form a negative-pressure environment.

3. The oil is sprayed and atomized in the vacuum tank to increase the contact area between the oil and the air, making it easier for the moisture to evaporate.

4. The evaporated moisture and gas are extracted by the vacuum pump and recovered after condensation by the condenser.

Through the treatment of the vacuum oil filter, the moisture and gas in the transformer oil are effectively removed, which improves the purity and insulation performance of the oil.

Adsorbent dehydration method

In addition to using a vacuum oil filter, an adsorbent dehydration method can also be used. This method mainly uses the hygroscopicity of the adsorbent to adsorb the moisture in the transformer oil. Commonly used adsorbents include silica gel, activated alumina, etc.

During the specific operation, the adsorbent is placed in the oil filter or oil tank and fully contacted with the transformer oil. The adsorbent absorbs the moisture in the oil, thereby reducing the moisture content of the oil. It should be noted that the adsorbent needs to be replaced or regenerated after a period of use to ensure its dehydration effect.

In short, the dehydration of transformer oil is an important part of ensuring the normal operation of the power system. By using effective means such as vacuum oil filters and adsorbents, the moisture content in transformer oil can be reduced, its insulation performance and heat dissipation effect can be improved, thereby extending the service life of the equipment and ensuring the stable operation of the power system.
