ZHONGNENG ZYD double stage transformer oil purifier has been specially designed for on site use to completely regenerate insulating oils in energized or de-energized transformers even when transformer power above 110KV and altitude over 500 meters, as well as purify mutual inductor oil, switch oil and so on. Also it can inject the insulating oil into the transformers on-line and dry the transformer.
ZHONGNENG designs and builds the most effective, durable, and easily operation high vacuum transformer oil purification system on the market today.
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. With Coalescer Elements
4. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
5. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
6. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
7. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
8.Adopt interlocked protective system,which connect oil pump,heater and liquid level sensor,avoiding blank heating,blank pumping.
9.Functions of live line work on-site,vacuum drying and vacuum oiling.
