1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa.
2. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
3. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
4. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies.
5. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
6. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
7. 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.
8. Functions of live line work onsite, vacuum drying and vacuum oil filling.
Comparing with the single-stage vacuum oil purifier, this machine adds ROOTS vacuum system, second stage of separating system to improve the effect of purification which dewater, degas and removes the impurities more quickly, more completely, and makes the oils limiting voltage-withstand value much higher. As the bridge-type vacuum linking system that can purify and also can be an independent vacuum power supply, this machine can treat the electric insulation devices
ZYD Double Stage High Vacuum Transformer Oil Purifier can remove the water, gas and impurities in insulation oil high-efficiently, increasing the pressure force and quality of oil, make sure the electric device running safely. The machine is mainly used for electric power department and industries to deal with various oils such as transformer oil, mutual oil, switch oil and so on. The machine is especially for purifying the insulation oil in all kinds of large power equipments that are above 110KV, especially for the altitude is over 500 meters.
