Description
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 FUOOTECH Series ZYD-T Double-stage & Two Vacuum Chambers Insulating Oil Purifier has been specially designed for on/off site use to completely purify insulating oils in energized or de-energized transformers even when transformer power both below and above 110KV and altitude over 500 meters, as well as purify mutual inductor oil, switch oil and so on. Also it can fill the insulating oil into the transformers on-line and dry the transformer.
The ZYD-T oil filtration machine combines the high quality rotary vane vacuum pump and booster roots pump which can speed up evacuation much faster, and combines two vacuum chambers which can separate water/moisture content and gas/air content more quickly and thoroughly, and improve/increase the transformer oil’s dielectric strength value much higher.
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.
Also, this oil filtration machine can be used to power equipments to vacuum drying, vacuum oiling, and vacuum pumping.
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. Two vacuum chambers installed to provide more efficient degassing and dehydration results.
3. Double-stage vacuum pump system, high vacuum pressure and high flow rate, strong power of vacuum evacuating
4. Advanced Multi-stage precision Purification system, stainless steel materials Purification combined with molecular adsorption filtering technologies
5. Besides the common vacuum oil Purification Machine’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.
6. UK G technology by which the trace water that is show chain, such as dissolved water, can be removed effectively.
7. Efficient electric high density oil heating system, heating uniformity, less power consumption, safe, and reliable.
8. Especially applied to vacuum oiling and drying (Hot Oil Circulation / on-site Drying) for power transmission equipments which are over 110KV.
9. 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 off automatically.
10. Advanced dielectric Condenser devices.
11. Flow Meter included for measuring oil flow rate.
12. Low maintenance cost and time, simple operation and maintenances.
BDV Test after treatment by our machine can reach 74.7kV
