PLC Control Switch Transformer Oil Centrifuging Machine , Oil
DVP series insulating oil purification equipment is widely used in
various large transformer installation and maintenance for hot oil
circulation and vacuum drying. 110KV-750KV high voltage or more,
EHV transformer insulating oil purification, also applies to
high-grade new oil, the high depth of processing imported
oil.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 ,it
can degas, dewater, and remove the acid value and impurity quickly,
The treated transformer oil have higher limit brake down voltage
value,It’s 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.
This is the automatic type of our DVP250 model transformer oil
purifier machine with PLC control parts,it can treat
250L/minute(15000L/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
∆ 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.
∆ Used for oil filling for transformers and circuit breakers under
∆ Precise filtration system, high-quality filter element ,
multistage filtration with gradual precision can help to remove
mechanical impurities in the oil.
∆ 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.
∆ Online work , allowing separated operation of manual operates
from machine with lamps indicating the condition for operation.
∆ It is humanization design with low noise , deep purification and
long time free maintenance to save cost from the running process.
∆ 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.
∆ Double stages vacuum source and dehydration, degasification
system, vacuum pump with roots pump, high speed vacuum evacuation,
ultimate vacuum ≤ 5Pa
∆ Automatic double-infrared liquid level controller, pressure
protector, which ensure long-term safely and reliable operation.
∆ Automatic defoaming system with dual electronic monitoring
system, which avoid the foam ejecting and gushing to vacuum pump.
∆ Horizontal double vacuum separation technology, doubling the
evaporation area and degassing time
∆ 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.
