This Double Stages Vacuum Transformer Oil Purifier is designed to purify electrical insulating oil used in oil-filled power equipment. It can effectively remove moisture, dissolved gas, solid particles, and oxidation by-products from transformer oil, switch oil, mutual inductor oil, cable oil, and capacitor oil.

The Transformer Oil Purifier is suitable for factory workshops, power plants, substations, transformer maintenance centers, and power transmission projects. It is especially useful for treating high-voltage transformer oil, new transformer oil, and aged insulating oil that requires dehydration, degassing, and precision filtration before reuse or operation.

Why Transformer Oil Needs Purification

Transformer oil gradually degrades during long-term service. Moisture may enter from ambient air, seals, insulation aging, or poor storage conditions. Dissolved gases can be generated by electrical and thermal stress, while oxidation products may increase oil acidity and sludge formation. Solid contaminants such as insulation fibers, metal particles, and dust can also reduce oil cleanliness.

Even a small amount of water or gas can lower breakdown voltage and accelerate insulation aging. Regular oil purification helps improve dielectric strength, restore oil performance, reduce maintenance costs, and extend the service life of transformers and other electrical equipment.

Double Horizontal Vacuum Evaporation System

This Transformer Oil Purifier adopts a double horizontal vacuum evaporation system with double-row spray nozzles. The design increases the oil evaporation area and extends the degassing time, allowing moisture and dissolved gases to escape from the oil more efficiently.

Under high vacuum conditions, the oil is dispersed into a thin film, which improves contact between oil molecules and the vacuum environment. This helps achieve faster dehydration and degassing performance, especially for high-voltage insulating oil treatment.

Working Principle

After passing through the primary filter, the oil enters the heating system and reaches the required treatment temperature. The heated oil is then sprayed into a thin film through the film sprayer and enters the vacuum separator.

Under vacuum and negative pressure conditions, water vaporizes at a lower temperature and is removed by the vacuum system. Dissolved gas is separated from the oil, while fine particles are captured through precision filtration. The treated oil becomes cleaner, drier, and more stable for transformer operation.
