1、 Characteristics of dry-type transformers:

1. Safe, fireproof, pollution-free, and can operate directly in the load center;

2. Adopting advanced domestic 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, significant energy-saving effect, maintenance free;

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

5. Good moisture resistance, suitable for operation in harsh environments such as high humidity;

6. Dry type transformers can be equipped with comprehensive temperature detection and protection systems. The intelligent signal temperature control system can automatically detect and display the working temperature of each three-phase winding, automatically start and stop the fan, and has functions such as alarm and trip.

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

2、 Cooling method for dry-type transformers:

The cooling methods for dry-type transformers are divided into natural air cooling (AN) and forced air cooling (AF). During natural air cooling, transformers can operate continuously at their rated capacity for a long time. When forced air cooling is used, the output capacity of the transformer can be increased by 50%. Suitable for intermittent overload operation or emergency overload operation; Due to the significant increase in load loss and impedance voltage during overload, it is not suitable to maintain continuous overload operation for a long time as it is in a non economic operating state.
