1)     Use oil purifier machine remove the water, gas and impurities in transformer oil thoroughly.


2)     Can add T501 antioxidants in oil.


3)     For more than 1000KVA transformer should at least take any anti deterioration solution of the follow:


a)     The new oil and regeneration oil include T501 should not be less than 0.3% ~0.5%. , the operating oil should not be less than 0.15%, when the content is lower than the prescribed value, should be added. When add T501, it should keep the oil PH value not less than5.0.


b)     Install the thermosyphon, the adsorbent dosage should be 0.5%~1.5% of the amount of oil.

3)     Vacuum pumping: remove dissolved air and other gases.


 


Zhongneng Series ZYD Double-stage vacuum transformer oil purifier is special for treating the new and old transformer oil. This machine adopts the double stages vacuum system, which can improve the machine working vacuum value highly, so it can remove the water, gas and impurities in transformer oil high-efficiently, increasing and maintain the oil's dielectric strength and quality of oil, make sure the electric device running safely.


 


Meanwhile, as the bridge-type vacuum linking system, Zhongneng Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying, vacuum filling oil for power Transformer.
