As is well known the Transformer plays an important role in the generation, transmission and distribution of electrical energy. Under load the transformer, dissipates heat and the insulating oil acts as a coolant as well as an effective dielectric.

Due to the highly hygroscopic nature of the transformer oil, it absorbs moisture from windings, which leads to gradual deterioration of dielectric strength. Also there are some waste impurities, gas contents in the transformer oil which destroy the oil’s quality. 

Series ZYD double stage vacuum transformer oil filtration machine is a double stages vacuum oil purification system, comparing single stage vacuum oil purifer, besides a rotary vane vacuum pump, ZYD machine installs one more booster roots pump vacuum system which speed up evacuation much faster.

The double stage vacuum transformer oil purifier adopts advanced horizontal vacuum chamber which has large area three-dimensional flash evaporation technique and remove water, gas, solids much quickly and completely. After purification by our Series ZYD transformer oil purifier, the oil breakdown voltage can reach up to 75KV.

Series ZYD 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 110V substation live 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. Duplex 3D stereo-evaporation, efficient oil film sprayer, eliminating the liquid water quickly, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.

2. Double-stage vacuum system, high vacuum pressure and high flow rate, strong power of vacuum evacuating,

3. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies

4. Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.

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. Functions of live line work onsite, vacuum drying and vacuum oiling.

Q: How can we achieve drying without elevated heating of the insulation material for transformers?

A: Drying of insulation materials can be achieved at low temperature and low pressure levels. The pressure levels and temperature levels for drying vary for distinct material. At low pressure or under vacuum the rate of water vapour evaporation is accelerated if sufficient heat is provided to the insulation material. Thus we can achieve a good drying of insulating material if the material is suitably heated and subjected to vacuum.
