Fully Automatic High Voltage Transformer Vacuum Oil Purifier
Machine Remove The Oil Water,Particles And Gas
DVP 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.
About this machine:
This DVP100 model transformer oil purifier machine is horizontal
type with PLC system,it design as two horizontal vacuum
chambers,can treat 100L/minute(6000L/hour) transformer oil,this
machine can be produced with Europe famous brand pumps.such as
Germany Leybold ,Kracht,ABB or China famous brand pumps as customer
required. This DVP100 automatic type transformer oil purifier
machine mostly suitable for power plant, power engineering, the
power supply house ,Hydroelectric power station,Wind power
station,Coal power station,transformer oil purify service agent
etc.
Features:
① Double-stage vacuum system, strong power of vacuum evacuating,
ultimate vacuum value ≤ 5Pa.
② Horizontal double vacuum separation technology, doubling the
evaporation area and degassing time
③ Two vacuum separating chambers, efficient oil film sprayer,
increasing separating size and separating time to ensure the
dry-level and dielectric strength improving greatly.
④ Duplex-Stereo film evaporation technology, combined with unique
and advanced dewatering, degassing components, can rapidly and
effectively separate water, gas from oil.
⑤ Automatic double-infrared liquid level controller, pressure
protector, which ensure long-term safely and reliable operation.
⑥ Pre Electromagnetic valve before vacuum pump to prevent the
vacuum oil flow backwards.
⑦ Automatic defoaming system with dual electronic monitoring
system, which avoid the foam ejecting and gushing to vacuum pump.
⑧ Pre gas water separator before vacuum pump to prolong the vacuum
pump and vacuum pump oil.
⑨ Adopt interlocked protective system, which connect 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.
⑩ Multi-stage precise filtration system with gradually increasing
precision, which can effectively remove mechanical impurities from
oil.
⑪ Optical oil foam detector and high oil level detector to prevent
oil escape from vacuum pump
⑫ Low oil level sensor to prevent oil pump idle working, so prolong
oil pump lifetime
⑬ Completely Intelligent pressure protector to protect oil pump and
fine filter
⑭ Completely Intelligent vacuum controller to protect the booster
pump
⑮ Advanced cooling system of vacuum pump, it reduces the frequency
of oil’s replacement and extends the life of vacuum pump.
