Types of Transformer Oil Regeneration Equipment

Transformer oil regeneration equipment is mainly used to restore the performance of transformer oil, remove aging products and pollutants in the oil, to extend the service life of the oil and ensure the normal operation of the transformer. According to different regeneration principles and technologies, transformer oil regeneration equipment can be divided into the following types:

1. Adsorption regeneration equipment:

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

- Suitable for treating mild to moderately aged transformer oil.

2. Vacuum dehydration and degassing equipment:

- Heat the oil under vacuum to remove moisture and dissolved gases.

- Suitable for treating transformer oil containing moisture and gas.

3. Centrifugal separation equipment:

- Use centrifugal force to separate moisture and solid particles in the oil.

- Suitable for treating transformer oil containing a large amount of moisture and particulate impurities.

4. Filtration regeneration equipment:

- Remove solid particles and some colloidal substances in the oil through filter elements or filter paper.

- Suitable for treating transformer oil contaminated with solid particles.

5. Chemical regeneration equipment:

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

- Suitable for treating transformer oil containing specific chemical pollutants.

6. Electrical purification equipment:

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

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

7. Thermosyphon regeneration equipment:

- Through the principle of thermosyphon, the oil is naturally circulated through the adsorbent after heating to achieve continuous regeneration.

- Suitable for online continuous treatment of transformer oil.

8. Composite regeneration equipment:

- Combine multiple regeneration technologies, such as adsorption, vacuum, filtration, etc., to improve the regeneration effect.

- Suitable for treating transformer oil with complex pollution.

When selecting suitable transformer oil regeneration equipment, factors such as oil pollution type and degree, processing volume, regeneration efficiency, equipment cost and operation and maintenance need to be considered. Generally, the regeneration treatment of transformer oil should be carried out under the guidance of professionals to ensure the treatment effect and equipment safety.
