Power manufacturers describe the structural characteristics of dry-type power transformers

Transformers are widely used in industrial manufacturing, high-rise buildings, airports, docks and other places. Dry-type power transformers are transformers in which the iron core and windings are not immersed in insulating oil. The cooling methods of dry-type power transformers are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, dry-type power transformers can operate continuously for a long time at rated capacity. When forced air cooling, the output capacity of the dry-type power transformer can be increased by 50%. It is suitable for intermittent overload operation, or emergency accident overload operation; due to the large increase in load loss and impedance voltage during overload, it is in a non-economic operation state, so it should not be used for long-term continuous overload operation.

Power Transformer Manufacturer-Due to the advantages of strong short-circuit resistance, small maintenance workload, high operating efficiency, small size, and low noise, dry-type power transformers are often used in places with high performance requirements such as fire prevention and explosion protection.

1. Stable, fireproof, less pollution, can run directly at the load point;

2. Adopt domestic advanced technology, high mechanical strength, strong short-circuit resistance, small partial discharge, good thermal stability, high reliability and long service life;

3. Low loss, low noise, obvious energy saving effect, maintenance-free;

4. Good heat dissipation performance, strong overload capacity, and can increase capacity operation when forced air cooling;

5. Good moisture-proof performance, suitable for operation in high humidity and other harsh environments;

6. Dry-type transformers can be equipped with a complete temperature detection and protection system. The intelligent signal temperature control system is adopted, which can automatically detect and display the working temperature of the three-phase windings, and can automatically start and stop the fan, and has functions such as warning and tripping;

7. Small size, light weight, less space occupation, low installation cost.

Power Transformer Manufacturer - Iron Core:

High-quality cold-rolled grain-oriented silicon steel sheet is used, and the iron core silicon steel sheet adopts a 45-degree full oblique joint, so that the magnetic flux passes along the joint direction of the silicon steel sheet.

Power transformer manufacturers - winding form: winding, epoxy resin plus quartz sand filling casting, glass fiber reinforced epoxy resin casting, multi-strand glass filament impregnated epoxy resin winding.
