This oil purification plant is applied to purify various of unqualified insulating oils including aging transformer oil specially for the power which is above 110KV, mutual inductor oil, switch oil and so on. Also it can inject the insulating oil into the transformers on-line.

 

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

3. Flash point ≥145℃   4. Anti-pressure≥60KV

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. Adopt Germany’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)

 

Comparing with the single-stage vacuum oil purifier, this machine 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.

 

All exposed ferrous(non-stainless) parts of this machine are hot-dip galvanized, and that all aluminum, aluminum alloys in contact or close to other metals are treated specially with the technology of spray-paint, which make the machine harder and have a very nice appearance.
