Leybold Double Vacuum Pump Type Used Insulating Oil Purifier
**Application:**
The DVP series double stages vacuum transformer oil purifier is specially designed for processing insulating oil of high voltage electric equipment (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:**
1. Horizontal double vacuum separation technology, doubling the evaporation area and degassing time
2. Double stages vacuum source and dehydration, degasification system, vacuum pump with roots pump, high speed vacuum evacuation, ultimate vacuum ≤ 5Pa
3. Multi-stage precise filtration system with gradually increasing precision, which can effectively remove mechanical impurities from oil.
4. Automatic double-infrared liquid level controller, pressure protector, which ensure long-term safely and reliable operation.
5. 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.
6. Automatic defoaming system with dual electronic monitoring system, which avoid the foam ejecting and gushing to vacuum pump.
7. Advanced cooling system of vacuum pump, it reduces the frequency of oil's replacement and extends the life of vacuum pump.
8. 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.
9. Online oil treatment, vacuum drying and vacuum oil-filling for electric equipments.
