High Voltage Electric Transformer Oil Purifier Machine Horizontal
On Line Work
Why purify transformer oil?
Dissolved gasses in transformer oil can cause arcing, corona
discharges, and overheating--reducing the electrical efficiency and
lifetime of the transformer. Likewise, water contamination at
levels as low as 30 ppm (parts per million) can adversely affect
the insulating strength of the oil. With ever-increasing standards
for energy efficiency of power distribution transformers, the need
to effectively degas will become even more important in the future.
particles contamination will also affect the function of insulating
oil. So we need to clean used transformer oil.
Application:
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.
Features:
◆ Horizontal double vacuum separation technology, doubling the
evaporation area and degassing time
◆ Double stages vacuum source and dehydration, degasification
system, vacuum pump with roots pump, high speed vacuum evacuation,
ultimate vacuum ≤ 5Pa
◆ 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.
