The Necessity of Vacuum Drying of Transformer

A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the iron core (magnetic core), primary coil, and the secondary coil. The main functions of the transformer are voltage transformation, current transformation, impedance transformation, isolation, etc.

Transformers can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, etc.

From the perspective of existing transformer products, winding materials in transformer installation generally include: iron core material, insulating material, impregnating material, etc. The installer must select it according to the actual situation.

Transformers are the basic equipment for power transmission and distribution, and are widely used in industry, agriculture, transportation, urban and other fields.

Vacuuming work is required when the transformer is filled with vacuum oil. Generally, in order to effectively expel the air bubbles in the transformer oil and improve the insulation level of the transformer, vacuum oiling is required for large transformers.

As the main electrical equipment of power plants and substations, the insulation strength of transformers directly affects the safe and stable operation of transformers. Generally, the insulation strength of the transformer is in the best state when it leaves the factory. After transportation and installation, it is inevitable that it will not be polluted, and the insulation strength will always decrease. The transformer can be dehydrated and degassed by vacuuming to improve the insulation strength.

The ZJ series transformer vacuum pumping units produced by YUNENG can perform vacuum pumping operations. Solve the problem of vacuuming the transformer for you.
