Why purify transformer oil?
After some time working, the hv power transformer maintenance jobs is important.
the outside moisture and dissolved gasses will enter inside the transformer, and the transformer oil will cause following problems: arcing, corona discharges, and overheating--reducing the electrical efficiency and lifetime of the transformer. Once the moisture reaches about 40ppm that it will affect the insulating strength of the oil. Plus particles contamination will also affect the dielectric oil’s breakdown voltage level. By use of our Model ZLS transformer oil purification system to clean and renew used transformer oil is necessary.
Functions:
This equipment CTBU Brand Model ZLS oil purification machine is one movable type machine to be mounted on skid wheels base with lifting hooks , mainly for increasing and maintain electrical insulating oil's BDV (breakdown voltage) such as transformer oil, circuit breaker oil, tap changer oil, etc. And To degasify to remove out moisture, free water, and soluble water, gas and filtering particles, residuals, etc. As well as vacuum drying the electrical equipment such as transformer and vacuum filling on the line, It is designed and manufactured for indoor and outdoor operation at site.
