Overview | High Vacuum Transformer Oil Treatment Plant

The High Vacuum Transformer Oil Treatment Plant manfactured by PureTech is for the treatment (dehydration, degassing and filtration) of mineral transformer oil. The High Vacuum Transformer Oil Treatment Plant are designed for transformer oil processing in workshops or in the fields, oil storage tanks, drums or directly in transformers. Purification of transformer insulating oil can be carried out off-load or on-load on customer's demanding.

Vacuum insulating oil purification plant is required for routine maintenance and repair work for power transformers, besides, new transformer insulating oil should be filtrated and dehydrated before filling into power transformers.

This Vacuum Oil Purifier is mounted on a common base with full frame and movable casters. For outdoor projects, a roadworthy trailer and weatherproof enclosure can be mounted.

Performances | High Vacuum Transformer Oil Treatment Plant

1. Water Removal: From 50 ppm down to less than 5 ppm.

2. Gas Removal: From 10% down to 0.1%.

3. Particulate Matter Removal:  99% of particles over 1 micron, or over 3 or 5 micron at customer's preference.

4. Dielectric Strength Improvement:  Up to 75 KV with double-stage high vacuum insulating oil purification plant.

Process | High Vacuum Transformer Oil Treatment Plant

The vacuum insulating oil purification plant is designed according to the different boiling points of water and oil. It mainly consists of a vacuum degassing chamber, heater, pre filter and fine filter, condenser, vacuum pump and roots booster pump, oil discharge pump and an electrical control cabinet.

The vacuum pump system draws out the air in the oil purification plant to form a vacuum. Under the action of atmospheric pressure, the insulating oil is drawn from storage tanks to the oil purification plant, it passes through the inlet pipe and enters the pre filter to eliminate larger particles, and then enters the electrical heater (thermostat is installed to ensure no overheating). The oil is heated to 45~65℃ (setting value can be adjusted) before entering the degassing chamber. The heated oil is rapidly rotated by the spray wing to separate the oil into semi-mist. The water and gases contained in the insulating oil are thoroughly exposed to vacuum,and are continuously sucked into the condenser by the vacuum pump. The waterand gas in the condenser is cooled. The oil in the vacuum degassing chamber is discharged by the oil discharge pump into the fine filter to filter out the smaller particulate impurities, thereby completing the entire process of quickly removing impurities, moisture, and gas in the oil, so that the clean transformer oil is discharged from the oil outlet valve.
