Transformer
insulating oil must be purified by transformer oil purifier, as the influence
of heat and electric field, the transformer oil in contact with oxygen is
gradually oxidized to various oxides, alcohols, aldehyde, acid etc, and form
insoluble gum and sludge precipitation. These various oxides reduce the
insulation performance of the transformer insulating oil,
Water and gas in transformer oil has two
forms: dissolved water and gas (saturation point) are in electric systems. And
free water and gas (above the saturation point) are in insulating oil.
Because the system leakage, untight seal,
long-term heat load, open storage etc, water and impurities in the air will
dissolved in oil.
Untreated transformer oil contains 50 to 60ppm
water and 10% to 20% air, in order to reach requirement, it must remove water,
gas and impurities under state of rated vacuum and temperature. So the oil
during use should be regularly purified by vacuum transformer oil purifier.
Dielectric properties of transformer oil
mainly depends on water, gas and impurities content. Even new oil storage and
transportation will inhale the gas and water, so new oil should be purified by transformer oil purification plant before using.
