Characteristics And Structure Of Dry-type Transformer
Temperature control system
The safe operation and service life of Dry Type Transformer depend largely on the safety and reliability of transformer winding insulation.
Cooling method
The cooling methods of dry-type transformers are divided into natural air cooling (AN) and forced air cooling (AF). When the transformer is cooled by natural air, it can operate continuously for a long time at rated capacity. When the transformer is cooled by forced air, 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 are large during overload, it is in a non-economic operation state, so it should not be in long-term continuous overload operation.
