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