The main function of transformer oil and ZANYO transformer oil filtration machine

Firstly, what`s the functions of transformer oil?

The main function of transformer oil:

A. the insulation effect: transformer oil is much higher than air dielectric strength. Insulation material soaked in oil, not only can improve the insulation strength, but also from the erosion of the moisture.

B. heat dissipation effect: the big specific heat of transformer oil, commonly used as a coolant. Transformer the heat generated by the runtime make inflation rising oil is heated, near the core and winding through oil and convection, heat through the radiator out, ensure the normal operation of transformer.

C.Arc suppression effect: in the oil circuit breaker and transformer on-load voltage regulating switch, switch contact arc can be created. Due to the transformer oil heat conduction performance is good, and under the high temperature of arc is to touch a lot of gas, producing high pressure, so as to improve the arc extinguishing performance of the medium, make the arc soon go out.

The performance of the transformer oil usually has the following requirements:

a. transformer oil density is smaller is better, as far as possible so that the the water and impurity precipitation in the oil.

b. to moderate viscosity, can influence the convection, is too small and will lower flash point.

c. high flash point should be as far as possible, generally should not be lower than 136 ℃.

d. should be low freezing point.

e. the impurities such as acid, alkali, sulfur and ash content is lower, the better, as far as possible to avoid them to corrosion

of tank insulation, wire, etc.

f. oxidation degree can not too high.Oxidation degree normally expressed as acid value, it refers to absorb the free acid in 1 gram of oil the required amount of potassium hydroxide (mg).

g. stability degree should not be too low, the stability degree is usually expressed in sediment of acid value test, it represents

the oil anti-aging ability

ZANYO vacuum transformer oil purifier is special designed for purifying insulating oil of high voltage electric equipments(especially for more than 500KV UHV insulating oil) in workshops or the field, storage tanks or drums, it adopts double stages vacuum source, double stages vacuum dehydration and degasification vessels, three stages precise filtration system, which can separate moisture, gas, particles and other harmful ingredients from oil much quickly and effectively to ensure the dry-level and dielectric strength improving greatly.. Meanwhile, ZYD-I,ZYD-II machine can be used for online oil treatment for transformers and vacuum drying and oil-pumping for electrical equipment. It is also applied to the above

110KV EHV transmission and distribution equipment, capacitor oil, cable oil, mutual inductor oil etc.
