What is the function of transformer vacuum pump?
Transformer vacuum pumps can be used in the transformer vacuum drying process of large power transformers, as well as vacuuming operations during vacuum oil filling.
The transformer is mainly assembled by iron core, coil and insulating material. Once the transformer is flooded, it will reduce the insulation performance of the insulating material, seriously affect the normal operation of the transformer, and even cause safety accidents.
After the transformer is assembled, it needs to go through the transformer vacuum drying process before adding transformer oil. In order to remove the moisture and gas in the insulating material, the moisture content is controlled within the limit required by the product quality to ensure that the transformer has sufficient dielectric strength and operating life.
What is Transformer Vacuum Oil Filling?
During the normal oil filling process of the transformer, it is necessary to remove the gas during the oil filling process in order to improve the insulation level of the transformer. Contains two methods:
- When there is no oil in the oil tank: in a vacuum state, slowly inject qualified transformer oil from the bottom of the oil tank.
- When the transformer oil tank is full of oil: at this time, vacuumize and degas the entire transformer.
