Purification Therapy of Transformer Oil

Purification Therapy of Transformer Oil

Transformer insulating oils need to do purification treatment, as the impact of heat and electric area, the transformer oil in contact with oxygen is gradually oxidized to numerous oxides, alcohols, aldehydes, acid and so on, as well as type insoluble gum and sludge precipitation. These various oxides decrease the insulation performance of the transformer insulating oil,

Water and gas in transformer oil has 2 forms: dissolved water and gas (dew point) remain in electric systems. As well as totally free water and gas (above the dew point) are in shielding oil.

Because the system leak, untight seal, long-term warm lots, open storage space and so on, water and also contaminations airborne will certainly dissolved in oil.

Untreated transformer oil includes 50 to 60ppm water as well as 10% to 20% air, in order to reach requirement, it needs to eliminate water, gas and pollutants under state of rated vacuum as well as temperature level. The oil during usage ought to be regularly detoxified by vacuum Transformer Oil Purification System.

Dielectric strength of transformer oil mostly depends upon material of water, gas as well as impurities. Even brand-new oil storage and transportation will certainly has the gas and also water, so new oil also should be dealt with by Transformer Oil Purification System prior to filling up right into transformers.
