Online Transformer oil purifier

On-Load tap changer oil purifier is mainly used for cyclic purification of the oil from bypass of the transformer and high voltage switch. It can effectively absorb the slight water and prevent the small mechanical particles by cyclic purifying system of the bypass while the main system is under normal working, and control the oil cleanness and dielectric strength in order to ensure the electrical parameter such as water content,flash point,break-down voltage and cleanness of the insulation oil, will not lower, and extend the repairing period and the life span of the transformer and high voltage switch.it ensures that the high volatge switch works safely during maintenance period.

Integrate the function of fineness filtration and dehydration..

it can effciently remove dissolved water, and control the water content,flash point and dielectrical strength.

it can efficiently remove particles in the oil,  so that control the oil cleanness up to Nas6

Water content,   lower than 20PPm

Suspended particles,  lower than 3μm

cleanness(NAS1638), lower than 6 Grade
