Transformer oil purification equipment is a device for removing solid impurities and moisture in oil through pressure filtration or vacuum evaporation, and can also be used for vacuum oil injection of transformer. It is widely used in oil purification and vacuum hot oil circulation drying during installation and maintenance of various large transformer equipment. Its dehydration, degassing, acid value removal, free carbon removal, etc. after treatment, the limit withstand voltage value of transformer oil is higher.

The main purposes of this equipment are as follows:

1. insulation function: transformer oil has much higher insulation strength than air. The insulating material immersed in oil can not only improve the insulation strength, but also avoid the erosion of moisture.

2. heat dissipation: the specific heat of transformer oil is large, which is often used as coolant. The heat generated during transformer operation causes the oil near the iron core and winding to expand and rise. Through the up and down convection of oil, the heat is dissipated through the radiator to ensure the normal operation of the transformer.

3. arc suppression: on the on load voltage regulating switch of oil circuit breaker and transformer, arc will be generated during contact switching. Because the transformer oil has good thermal conductivity, and can contact a large amount of gas under the high temperature of the arc, resulting in a large pressure, so as to improve the arc extinguishing performance of the medium and make the arc extinguish quickly.

4. sealing function: transformer oil is widely used as sealing fluid in hydraulic safety valve, and is used for sealing oil immersed equipment and field vacuum oil injection and oil replenishment of equipment vacuum pumping.
