vacuum transformer oil recycling device ZYD

Series ZYD Double-stage-vacuum transformer oil purifier can completely and quickly remove water, trace water, gas,

particles as well as other harmful ingredients from oil to improve oil's dielectric strength, effectively making sure electric

equipments working safely and normally. Series ZYD vacuum oil purifier is particularly suitable for treating high-grade

transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than **0V

substationlive line work onsite. Meanwhile, Series ZYD oil purifier can be used as independent vacuum source with

functions of vacuum drying and vacuum oiling.

Features
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 offautomatically.
8. Special oil pump is suitable for working under high vacuum states, low noise, working reliable.
9. Photoelectric oil foam sensor, automatic eliminating oil foam, making sure vacuum pump working safe and stable.
*0. Optional choice of installing moisture sensor to test oil's moisture online.
*1. Functions of live line workon-site, vacuum drying and vacuum oiling.

Advantages
Comparing with traditional vacuum transformer oil purifier, Series ZYD oil purifier can increase the working

effectiveness more than three times, more quickly and completely dewater, degas, remove particles to get

higher dielectric strength. This equipment can be used as independent vacuum source with the functions of

vacuum drying and vacuum oiling for the electric plants.
