Multi Stage Transformer Oil Dehydration Machine Oil Water Separator 18000 L/hour



As is well known the Transformer plays an important role in the generation, transmission and distribution of electrical energy. Under load the transformer, dissipates heat and the insulating oil acts as a coolant as well as an effective dielectric.Due to the highly hygroscopic nature of the transformer oil, it absorbs moisture from windings, which leads to gradual deterioration of dielectric strength. Also there are some waste impurities, gas contents in the transformer oil which destroy the oil’s quality.


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, Compared with the single-stage vacuum, the machine increases the Roots pump pressurization system,secondary high vacuum separation systems ,infrared progressive scan automation systems and three-dimensional flash emergency rapid evaporation 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,The treated transformer oil have higher limit brake down voltage value


Meanwhile, DVP machine is not only used for oil purifier but also as a separate vacuum source which have the function of vacuum drying and oil injection for transformer equipment. It is also applied to the above 110KV EHV transmission and distribution equipment, capacitor oil, cable oil, mutual inductor oil etc.



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

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

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

⊿ Fully automatic temperature controlling system and multi-stages electric oil heater adopts low-load design to ensure uniform heating oil, the load is less than 1.0W/cm2, oil level and temperature protection of heater, which avoid cracking and aging of oil.

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

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

⊿ Interlocked protective system connects oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.

⊿ Online oil treatment, vacuum drying and vacuum oil-filling for electric equipments

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

⊿ Based on the high efficient vacuum oil purifier, Roots vacuum booster system and secondary high vacuum separation system are added, which enable the vacuum limit reaching ≤5Pa.

⊿ Being able to remove water and gas fast and effectively under high vacuum and high speed operation status,drying the insulating oil very well, improve the breakdown voltage up to 75 KV quickly. Have a big improvement on the one time purification result,reduce the dangerous of oil aging caused by repeat heating on the ordinary oil purifier.

⊿ Being able to remove the trace moisture and various gas in the oil rapidly, ensure zero acetylene existence in the oil. ZYD double stage transformer oil purifier has vacuum oil filling and vacuum drying function.
