Characteristic Structure Of Dry-type Transformer

Temperature control system:
The safe operation and service life of a dry-type transformer largely depend on the safety and reliability of the transformer winding insulation.
Cooling method:
Dry-type transformer cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). When naturally air-cooled, the transformer can operate continuously for a long time at rated capacity. When forced air cooling is used, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency overload operation; because the load loss and impedance voltage increase greatly during overload, it is in a non-economic operating state, so it should not be placed in long-term continuous overload operation.
