How to deal with transformer oil?

Transformer oil treatment usually involves the following steps to ensure that the oil properties are restored or maintained to ensure the normal operation of the transformer:

1. Filtration:

- Use oil filters to remove solid particles and some water from the oil.

- Plate and frame oil filters, cartridge oil filters or centrifugal oil filters can be used.

2. Vacuum dehydration and degassing:

- Heating the oil under vacuum to remove water and dissolved gases.

- Use vacuum oil filters for deep dehydration and degassing.

3. Adsorption treatment:

- Use adsorbents (such as activated alumina, silica gel, etc.) to remove acids, colloids and other polar substances in the oil.

- Can be carried out by thermosyphon regeneration equipment or adsorption oil filters.

4. Chemical regeneration:

- Use chemical agents to react with aging products in the oil to generate filterable or precipitable substances, which are then removed.

- Suitable for treating transformer oil with specific chemical contaminants.

5. Electrical purification:

- Use the electric field to charge and aggregate the particles in the oil, which is convenient for subsequent filtration or precipitation removal.

- Suitable for treating transformer oil containing tiny particles and colloidal substances.

6. Testing and analysis:

- Before and after treatment, the transformer oil should be tested to evaluate the quality of the oil and the treatment effect.

- The test items include breakdown voltage, moisture content, acid value, dielectric loss factor, etc.

7. Maintenance and monitoring:

- Regularly sample and analyze the transformer oil to monitor the quality changes of the oil.

- Decide whether further treatment or oil replacement is needed based on the test results.

The treatment of transformer oil should be carried out under the guidance of professionals to ensure the treatment effect and equipment safety. Relevant safety regulations and operating procedures should be observed during the treatment process to prevent oil pollution and environmental pollution. In addition, the treatment and replacement of transformer oil should follow the recommendations of the equipment manufacturer and the standards of the power industry.
