Leybold Double Vacuum Pump Type Used Insulating Oil Purifier
Application:
The DVP series double stage vacuum transformer oil purifier is specifically designed for processing insulating oil of high voltage electrical equipment (especially for UHV insulating oil over 500KV) in workshops or the field, storage tanks, or drums. It adopts a double-stage vacuum source, double-stage vacuum dehydration and degasification vessels, and a three-stage precise filtration system. This enables the quick and effective removal of moisture, gas, particles, and other harmful substances from the oil, significantly improving the dry level and dielectric strength. Additionally, the DVP machine can be used for online oil treatment for transformers and vacuum drying and oil-pumping for electrical equipment. It is also applicable to EHV transmission and distribution equipment above 110KV, capacitor oil, cable oil, mutual inductor oil, etc.
Features:
1. Horizontal double vacuum separation technology, doubling the evaporation area and degassing time.
2. Double-stage vacuum source and dehydration, degasification system with roots pump, enabling high-speed vacuum evacuation and ultimate vacuum ≤ 5Pa.
3. Multi-stage precise filtration system with gradually increasing precision, effectively removing mechanical impurities from the oil.
4. Automatic dual-infrared liquid level controller and pressure protector, ensuring long-term safe and reliable operation.
5. Fully automatic temperature control system with multi-stage electric oil heater, using low-load design to ensure uniform heating of the oil. The load is less than 1.0W/cm², with oil level and temperature protection to prevent oil cracking and aging.
6. Automatic defoaming system with dual electronic monitoring, preventing foam ejection and gushing into the vacuum pump.
7. Advanced cooling system for the vacuum pump, reducing the frequency of oil replacement and extending the life of the vacuum pump.
8. Interlocked protective system connecting the oil pump, heater, and liquid level sensor, avoiding blank heating, blank pumping, oil leakage, and electrical leakage. If there is any fault, the machine will automatically power off.
9. Online oil treatment, vacuum drying, and vacuum oil-filling for electrical equipment.
