Transformer Description
Dry-type transformer has many types you can to choose. They have epoxy resin cast dry-type transformer, non-encapsulated dry type transformer, amorphous alloy dry type transformer, three-dimensional wound core dry-type transformer.
Dry-type transformer is a high-performance electrical equipment. It adopts advanced insulation technology, does not require oil immersion, and is safe and environmentally friendly. It is fireproof and explosion-proof, and its operation is stable and reliable.
Transformer Adavantage
1. Low loss, low partial discharge, low noise, strong heat dissipation, and can be operated at 120% rated load under forced air cooling.
2. It has good moisture-proof performance and can operate normally under 100% humidity. It can be put into operation without pre-drying after shutdown.
3. It is safe to operate, fire-resistant, non-polluting, and can be installed directly in the load center.
4. Equipped with a complete temperature protection control system to provide reliable protection for the safe operation of the transformer.
5. Maintenance-free, simple installation and low overall operating cost.
6. According to the operation research of the products that have been put into operation, the reliability of the products has reached the international advanced level.
Basic Structure
1. Iron core: stacked by silicon steel sheet, is the magnetic circuit part of the transformer, used to guide the magnetic flux.
2. Winding: divided into high-voltage winding and low-voltage winding, respectively wound on the iron core, used to realize the conversion and transmission of electric energy.
3. Insulating cylinder: placed between high and low voltage coils, used to increase electrical insulation and ensure the safe operation of the transformer.
4. pads: used to support and restrain the coils to maintain their stability and shape.
5. Fasteners: used to connect and fix each part of the transformer, with anti-loosening performance.
Dry-Type Transformer Charateristic
Epoxy resin pouring transformer is a solid insulation encapsulated winding power transformer. Epoxy resin dry-type transformer uses epoxy resin as insulation material. High and low voltage winding is made of copper strip (foil), epoxy resin is poured and solidified in vacuum to form high strength FRP body. Insulation grade is F and H.
