Sino-NSH VFD Series Transformer Oil Purifier Plant For Transformer
Oil Purifier Oil Filtration
general
NSH vacuum insulating oil purifier is used for the purification and
treatment of insulating oil, oil filling and drying of electrical
equipment such as transformers.This series of products can effectively purify trace water, gas and
particulate matter.According to different practical uses, it is divided into three
modes:
•VF: Single stage vacuum transformer oil purifier
•VFD: Two-stage vacuum transformer oil purifier
•VFD-R: Two-stage vacuum oil purification and regeneration device
•VFD-A: Advanced automatic vacuum insulated oil purifier
Tailored: Tailored vacuum oil solution
Process description of the purifier
The oil to be purified is fed into the system by differential
pressure method.The oil is filtered through a coarse filter to prevent any
particles.The oil is then heated to a pre-selected temperature through an
electric heater to improve the purification effect, and directly
into the vacuum chamber for dehydration and degassing.
The vacuum chamber maintains a high vacuum for the most efficient
handling.
The oil is transferred back to the transformer through the fine
filter column through the oil pump. The filter capacity of the fine
filter column is up to 5-1 microns.
Performance Value
NSH double stage vacuum system is used to decrease total water
content (ppm), gasses and impurities present in insulation fluid.
After treatment, water content is decreased to less than 5 ppm,
while total gas content is reduced down to less than 0.1%.
Particulate matter is lowered to less than 99% of particles over
5-1 microns (filtration precision is selectable).
