High Ultimate Vacuum Transformer Oil Filtration System For Insulating Oil Regeneration
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 is high ultimate vacuum type of our DVP100 model transformer oil purifier machine with two stages vacuum pumps,it can treat 100L/minute(6000L/hour) transformer oil,insulating 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 DVP100 automatic type transformer oil purifier machine mostly suitable for power substation,power plant, power engineering,the power supply house ,transformer oil purify service agent,electric power,railway,petrochemical etc.
Features:
► 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 equipment,it can make continuous work more than 200 hours,do the internal cycle work as customer required to remove the moisture.
► 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.

Advantage:
► Comparing with the single-stage type, this series adopts the double-stages vacuum system, which immensely raises the machine's working vacuum degree, so it can dewater, degas and remove particulate impurities much more efficiently.
► Besides that, a special design enables this model to regenerate seriously deteriorated oil by removing the polarity materials, such as the deep oxides, free carbon effectively.
► It allows the power transmission equipment to remain in-service while impurities from it are effectively removed.
