Transformer Vacuum Pump Machine Manufacturer

Your Reliable Transformer Vacuum Pump Machine Supplier in China

YELOCO Series YHVS Vacuum pump machine is adapt to pump out gas in vessel , so as to make the vessel live up to required vacuum degree, as well as vacuum drying or other systems used for acquiring vacuum condition, especially adapt to the vacuum operation of transformer. Besides this sector, it can also be used in sectors such as vacuum melting, vacuum heat treatment, oil filter, weld, chemical pharmaceutical engineering, vacuum coating, electric parts and components and for pumping gas which doesn’t react with vacuum pump oil.

Vacuum Drying For Transformers

We know that a large amount of insulating material is installed inside the transformer. Once the transformer material is damp or water enters, the insulating performance of the insulating material will be reduced, which will not only expand the insulating material but also affect the geometric size. Moreover, it will have a serious impact on the normal operation of the transformer, affect the service life of the transformer, and even cause safety accidents.

Due to the material of the transformer, during the installation and transportation of the transformer, it is easily affected by the environment, which causes the transformer to be damp. We will take some effective drying methods to ensure the safe operation of the transformer. Transformer vacuum drying not only plays an irreplaceable role in the transformer manufacturing process but also is an important part of the maintenance after the transformer enters the water.

Vacuum Oiling For Transformers

Reasons for vacuum oiling of transformers

1. In order to effectively expel the air bubbles in the transformer oil;
2. Improve the insulation level of the transformer;
3. When the potential difference between turns of the coil is large, prevent the occurrence of air bubbles from causing breakdown between turns.

Large transformers generally have higher voltage and larger capacity, and the internal structure of the transformer is also more complicated. During normal oil filling, in order to eliminate the gas during the oil filling process, vacuuming is a more effective measure. Therefore, for large transformers, vacuum oiling is required.

Therefore, we can use a transformer vacuum extraction machine with a vacuum pump to achieve the purpose of vacuum drying and vacuum oiling.
