ZYD transformer oil purifier is mainly used for purification of oil for transformer with voltage higher than 220kv. It can increase oil breakdown voltage by at least 50kv, reducing moisture content from 150ppm to 3ppm.ZYD series are suitable for oil treatment, vacuum oil injection, and cyclic hot-oil drying in the installation and maintenance of big transformers.
1.Operational control can be switch- andrelay-logic or PLC with touchscreenOnline test and monitoring equipment
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.Precise filtration system,high-quality filter element,multi-stage filtration with gradual precision can help to remove mechanical impurities in the 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.
