Interlocked Protective Transformer Oil Purifier

Automatical Vacuum Transformer Oil Purifier Machine With Interlocked Protective System



DVP series double stages vacuum transformer oil purifier is special designed for processing insulating oil of high voltage electric equipments(especially for more than 500KV UHV insulating oil) in workshops or the field, storage tanks or drums, it adopts double stages vacuum source, double stages vacuum dehydration and degasification vessels, three stages precise filtration system, which can separate moisture, gas, particles and other harmful ingredients from oil much quickly and effectively to ensure the dry-level and dielectric strength improving greatly.. Meanwhile, DVP machine can be used for online oil treatment for transformers and vacuum drying and oil-pumping for electrical equipment. It is also applied to the above 110KV EHV transmission and distribution equipment, capacitor oil, cable oil, mutual inductor oil etc.


About this machine:

This is the automatic type of our DVP50 model transformer oil purifier machine with PLC control parts,it can treat 50L/minute(3000L/hour) transformer oil,this machine used Europe famous brand Germany Leybold vacuum pump and China famous brand root pump,we also could supply the Europe famous brand root pump as customer required. This DVP50 automatic type transformer oil purifier machine mostly suitable for power plant, power engineering, the power supply house ,transformer oil purify service agent.



1. Advanced dehydrating and degassing system that uses large area three-dimensional flash distillation technique to remove harmful composition in the oil such as water, air and gas.
2. Used for oil filling for transformers and circuit breakers under vacuum condition.
3. Precise filtration system, high-quality filter element , multistage filtration with gradual precision can help to remove mechanical impurities in the oil.

4. An advanced fully automatic temperature controlling system , liquid-level controlling system ,defoaming controlling system, pressure protecting system and excellent configuration can ensure operation of the equipment with high performance.

5. Online work , allowing separated operation of manual operates from machine with lamps indicating the condition for operation.

6. It is humanization design with low noise , deep purification and long time free maintenance to save cost from the running process.

7. Purifiers are equipped with a chain safety protective system, an interlocking of oil drainage system ,vacuum system and heating system which avoids any possible negative impacts caused by mal-operation.

8. Horizontal double vacuum separation technology, doubling the evaporation area and degassing time

9. Automatic double-infrared liquid level controller, pressure protector, which ensure long-term safely and reliable operation.

10. Automatic defoaming system with dual electronic monitoring system, which avoid the foam ejecting and gushing to vacuum pump.

11. Double stages vacuum source and dehydration, degasification system, vacuum pump with roots pump, high speed vacuum evacuation, ultimate vacuum ≤ 5Pa

12. Multi-stage precise filtration system with gradually increasing precision, which can effectively remove mechanical impurities from oil.

13. Advanced cooling system of vacuum pump, it reduces the frequency of oil’s replacement and extends the life of vacuum pump.
