Oil Filtration

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 Vacuum Transformer (Series ZYD-EX) has been specially designed for on site use to completely regenerate insulating oils in energized or de-energized transformers even when transformer power both below and above 100kva, 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-EX 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 type is also specially designed for explosion proof, applied with complete explosion proof measure and operated in some dangerous area. The explosion proof class is normally ExdBT4, CT class is also available to design. It can meet requirement in various dangerous environments.

Feathers

  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, stainless steel maiterials filters 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. UK G technology by which the trace water that is show chain, such as dissolved water, can be removed effectively
  6. 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.
  7. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
  8. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
  9. Functions of live line work onsite, vacuum drying and vacuum oiling.
  10. 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.
  11. PLC Controller is also available to install on the machine making the whole operation controlled by PLC fully automatically
