PureTech mobile Single Stage Vacuum Transformer Oil Purifier (Model VOP) is used for Transformer Oil Dehydration, degassing and filtration. It is widely applied in low voltage power transformers, oil circuit breakers, inductors and other oil-filled electrical equipment. This vacuum Transformer Oil Purifier can significantly improve the properties of unqualified transformer oil, such as breakdown voltage, moisture content, gas content, particulate content and other factors which affect the dielectric strength of transformer oil.
Model VOP adopt one vacuum pump, and suitable for low voltage transformers, such as 66KV. For high voltage or ultra high voltage power transformers, the Double-Stage High Vacuum Transformer Oil Purifier (Model DVOP) developed by PureTech is your good choice, which adopt double stage vacuum pumps, can effectively remove the water and gas from transformer oil, as well as improve BDV of insulating oil. Furthermore, Model DVOP can also be used as an vacuum drying and vacuum filling equipment during transformer maintenance.
1. Transformers oil enter into the Oil Purification Machine by the means of pressure difference.
2. It will firstly passes through the primary filter which can filter out mechanical particles, and protect the oil pump.
3. Then the oil is being heater by a eletrical heater which has constant temperature controller, thermal vacuum treatment is proved to be the most effective way for oil dehydration and degassing.
4. The heated oil flows into the vacuum chamber where dehydration and degassing happens, the moisture and gas separated from oil will be drained by the vacuum pump or condensed into water stored in the water tank.
5. Transformer oil after dehydration and degassing will be pumped out of the oil purification system after passing through the fine filter which can filter out small impurities, to ensure the cleanliness of oil.
6. This machine can realize inner cycle or external cycle when oil circulation is required.
