Application:

Series ZYD Double-stage vacuum transformer oil purifier is special for treating the new and old transformer oil, mutual oil, switch oil. Comparing with the single stage type, this machine adopts the double stages vacuum system, which can improve the machine working vacuum value highly, so it can remove the water, gas and impurities in transformer oil high-efficiently, increasing and maintain the oil's dielectric strength and quality of oil, make sure the electric device running safely.

Meanwhile, as the bridge-type vacuum linking system, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying, vacuum filling oil.

Feature:

1. PH of treat oil ≥5.5   2. Acid value ≤0.03mgkoH/g

3. Flash point ≥145℃   4. Anti-pressure≥80KV

5. Dielectric loss: Dielectric loss: tg δ (90°C)% ≤0.001

6. High vacuum: high point-vacuum ≤5Pa; working-vacuum ≤35Pa

7. High absorption speed: absorption speed power ≥333L/Sr.

8. Duplex 3D stereo-evaporation, eliminating the liquid water quickly

9. UK G technology, by which the trace water that is show chain, such as dissolved water, can be removed effectively

10. Instinctively removing impurities system filtering through the double FH trapezoidal network and absorbing by high polymer without mechanical power

11. Argon fiber infrared heating system that can make the oil contain zero sum of ethyne after the treatment.

12. Advanced infrared oil level control system and pressure protection device make operation simple and safe.

13.  The equipment is installed with auto alarming system, it will give out alarm and stop the whole machine when electrical motor is overloaded, vacuum pump and oil pump overloaded, heater overloaded and pressure abnormal.

14.  Adopt a trinity of interlocked preventive device.

15.  AdoptGermany's 3UG3 Phase Relay. ­­

16. It can purify transformer oil on-line without cutting off the power

17. The machine with PLC can operate automatically. (optional)
