Application
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.
The Zhongneng Oil regeneration system (Series ZYD) has been specially designed for on site use to completely regenerate insulating oils in energized or de-energized transformers even when transformer power above 110KV and altitude over 500 meters, as well as purify mutual inductor oil, switch oil and so on. Also it can inject the insulating oil into the transformers on-line and dry the transformer.
The ZYD system not only provides regular oil purification/ reclamation such as degassing, drying and particulate removal, but also can remove acidity, sludge, carbon deposits, sulfur, and other soluble oil decay products and improve physical & chemical properties comparable to new transformer oil.
This is accomplished by the use of high vacuum degasification technology and particulate filters combined with our special brand of earth. After treating, the oil can be reused as new.
Features:
1. Duplex 3D stereo-evaporation, eliminating the liquid water quickly.
2. Besides the common vacuum oil purifier's function of dewatering, degassing and eliminating particles, this machine can regenerate the seriously deteriorated oil by removing the polarity materials, such as the deep oxides, free carbon in the oil effectively. It can make the seriously deteriorated oil reach to the normal index like anti-oxides, acid-alkali water-solubility.
3. UK G technology by which the trace water that is show chain, such as dissolved water, can be removed effectively.
4. Distinctive removing impurities system filtering through double FH trapezoidal network and absorbing by high polymer without the mechanical power
5. Carbon fiber infrared heating system that can make the oil contains zero sum of ethyne after the treatment
6. Especially applied to vacuum oiling and drying (Hot Oil Circulation / on-site Drying) for power transmission equipments which are over 110KV
7. Contains Transformer Evacuation System
8. Advanced dielectric Condenser devices.
9. Low maintenance cost and time.
10. Can be operated both on-load and off-load.
11. Can be operated fully-automatically with PLC controller as option.
12. This Oil purifier can be made in mobile type with trailer, hermetical, canopy-covering, open and frame style
Advantages:
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.
