The Description Of Dry-type Transformer
- Nov 03, 2017 -

Dry type transformer is widely used in local lighting,high-rise buildings, airports, docks CNC machinery and equipment and so on, in short dry type transformer is referred to as core and winding don't dip in insulating oil of transformers.

The cooling method is divided into natural air cooling (AN) and forced air cooling (AF).In natural air cooling, the transformer can run continuously at rated capacity.The output capacity of transformer can be increased by 50% when forced air cooling.It can be used for intermittent overload operation or emergency overload operation.Because load loss and impedance voltage increase greatly in overload, it is in non-economic operation state, so it should not be in a long time continuous load operation.
