Application | High Vacuum Transformer Oil Filteration and Regeneration Machine

transformer oil regeneration plant for used transformer oil treatment,improve oil dielectric strength

Nowdays, the transformer oils are widely applied to various oil-filled equipment as the media of cooling, insulating, and the dielectric properties of protecting the active part. Transformer oil is highly refined oil that consist mainly a mixture of hydrocarbons. Therefore, with long-term running, oxidation by-products and decaying products start to form in the transformer oil, which will further result in the increases of acidity (neutralization number), as well as the decreases of interfacial tension of insulating oil. The law of change is that it increases with the oxidation of oil, and after a certain depth of oxidation, it may sometimes undergo polymerization and condensation reactions under certain conditions because of the generated acid, water, ketone, aldehyde, alcohol, etc. At this time, Resin, asphaltene, etc. not only does the acid value not increase, but it will decrease. The resinous and asphaltenes produced at the same time can increase the oil's hygroscopicity, that is, the oil's ability to dissolve water increases. If the moisture resistance is not good, it will directly cause the moisture to increase faster than the new oil.

At this stage, the sludge forms in the transformer oil will cause the insulating oil losing its dielectric strength, we call it used oil or old oil. If keep running the old oil without regenerating, the further deterioration of transformer oil will cause the damage to the active part of power transformers or other electrical equipment.

PureTech Double-Stage High Vacuum Transformer Oil Regeneration Machine (Model DVOP-R) is a designed for transformer oils under such conditions. It has double stages vacuum pump system for oil dewater and oil degassing, three stages filtration for particulate removal, and regeneration device for removal of acidity, sludge, oxidation,etc. Finally the used transformer oil after regeneration will become qualified oil again, which has similar oil properties of new transformer oil.

Features | High Vacuum Transformer Oil Filteration and Regeneration Machine

• Significantly improve the acidity, tan delta, interfacial tension, breakdown voltage, as well as oil color.

• Double-stage sufficient vacuum ensures the effect and efficiency of water removal.

• Three-stage filtration ensures the particulate filtration capacity.

• Instead of buying new oil, Transformer Oil Regeneration save much cost.

• Multifunctional integrated equipment, can be used oil treatment, vacuum oil filling and vacuum drying. (*More functions can be customized according to your requirements.)

• The uniquely designed “T” vacuum chamber enlarges the oil evaporation area more than the traditional design, so as to achieve a better dehydration and degassing effect.

• Transformer Oil Regeneration System can work offline or online under the safe operation.

• The regeneration device can be switched on/off separately without influencing the working of transformer oil degassing.

• The adsorbents inside oil regeneration can be easily replaced when needed.

• Online oil testers, trailer type with road-worthy wheels, weather-proof enclosure and other spare parts are available for selection.
