Transformer Oil Filter Machine

Transformers require filtered and dried oil. During its usage, the transformer oil absorbs moisture and gets polluted by sopping fibers, dirty particles, aging products, and soot. Even new transformer oil is not clean enough as it may have absorbed moisture from the air or may have got polluted in the barrel it was stored in. Hence, Transformer Oil Filtering is an important process before transformer oil filling. 

PureTech vacuum oil filtration machine is used for treatment of transformer oil, includes dehydration of transformer oil, vacuum degassing of transformer oil, as well as transformer oil filtration. Transformer oil filtration procedure eliminates solid particles, dissolved gasses, free and dissolved water. The electrical properties of the oil can be enhanced by filtering, dehydration, and degassing. Oil Filtering keeps the transformer in good condition and increases its life.

Model VOP Single-Stage Vacuum Mobile Transformer Oil Filter Machine is widely applied in low voltage power transformers (below 66KV), oil circuit breakers, inductors and other oil-filled electrical equipment. For high voltage or ultra-high voltage power transformers (above 110KV), Model DVOP Double-stage High-Vacuum Transformer Oil Filtration Machine is recommened, which adds a roots booster pump at the basis of rotary vane vacuum pump, greatly improve the speed of vacuuming as well as the ultimate vacuum. Model DVOP can also be used as an vacuum drying and vacuum filling equipment during transformer maintenance.


Transformer Oil Filtration Procedure

1. Transformers oil enter into the oil filtration machine by the means of pressure difference (Operate the vacuum pump, negative pressure is formed inside the equipment; Oil inlet pump can be OPTIONAL).transformer oil dehydration, degassing and filtration

2. Oil will firstly passes through the primary filter which can filter out large-size mechanical particles, besides, protect the oil pump from damage by large mechanical particles.

3. Then the oil is being heater by a eletrical heater which has thermostat. Transformer oil is heated evenly, local overheating is avoided. Temperature can be adjusted from 40 degrees to 85 degrees, normally 60~65 degrees is recommended.

4. The heated oil flows into the vacuum chamber where dehydration and degassing happens, thermal vacuum treatment is proved to be the most effective way for oil dehydration and degassing.

5. Moisture and gas separated from transformer oil will be drained by the vacuum pump or condensed into water and stored in the water tank. (Model DVOP has two stage vacuum pump system.)

6. Transformer oil after dehydration and degassing will be pumped out of the oil purification system after passing through the two-stages fine filters which can filter out small impurities, to ensure the cleanliness of oil.

7. Sampling valve can be turned on when oil sampling and transformer oil testing is required. This machine can realize inner cycle or external cycle when oil circulation is required.

8. Optional oil testing instruments are recommended for online transformer oil testing and monitoring of oil filtration procedure.


PureTech Transformer Oil Filtration Systems

1. Model VOP Single-Stage Vacuum Transformer Oil Filtration Machine (suitable for below 66KV power transformers and swtiches)

2. Model DVOP Double-Stage Vacuum Transformer Oil Filtration Machine (suitable for high voltage above 110KV power transformers and swtiches)
