YZS Transformer Oil Regeneration Machine

  1. The transformer oil regeneration machine is particularly suitable for regenerating used and aged transformer oils and insulating oils.
  2. The two-stage vacuum transformer oil regeneration system not only provides the functions of dehydration, removal of impurities, but also removes the decay products and discoloration of acidity, sludge, free carbon, deep oxides and other soluble oil. It can increase the voltage of the insulating oil, make the indexes of the insulating oil such as acid and PH reach the national standard, and increase the index of the insulating oil. This is achieved through the use of high vacuum degassing technology and particulate filtration machine, as well as our special fuller earth. After processing, the oil can be reused.

Product Introduction

  • The transformer oil regeneration plant integrates the purification technology of low-temperature physical adsorption (reduce dielectric loss, decolor and deodorant) and online regeneration adsorption filters, etc, features high-speed purification and oil quality protection, etc. It can efficiently remove moisture, impurities, oxidative deterioration matter, hydrocarbons, and chromosome gum and other harmful substances n in oil. After decoloring and filtration with the machine, the oil will be as clean and clear as the new oil, especially the dielectric loss index of the transformer oil will be recovered nearly the same with new oil’s standards,which ensures long-term circulation usage of oil.
  • The absorption filters of the machine have a regeneration function, which could be repeatably used, so as to reduce consumable investment, save costs and reduce pollution.


Features of Transformer Oil Regeneration Plant

  1. It doesn’t need Acid and alkali process, simple processing and reduces the cost of oil filtration. 
  2. The full process is physical purification. The oil can be recovered and the additives in the oil won’t be damaged.
  3. The operation is under full-closed, safety and environmental protection. 
  4. Extend the lifetime of antioxidants and additives by removing the oxidizing material in the oil. 
  5. Good results on the decolorization. It can restore the unqualified transformer oil to be clean qualified oil. 
  6. The absorption agents can be reused after activated and regenerated by the regeneration system so as to extend the filter life cycle.

Advantages of Transformer Oil Regeneration Machine

  1. It restores used oils to new like condition. This process makes it possible to fill transformers with oil that would previously have required disposal. The oil in the transformer can be used without replacement for the entire service life of the transformer.
  2. Itis designed to extend transformer service life by restoring the dielectric strength and chemical composition of dielectric insulating oil.
  3. It process of oil regeneration, oil degradation products and acidic compounds are removed, the oil becomes clear, oxidation resistance is improved, while gas solubility is reduced.
