[0002] Dry-type transformers are widely used in places such as local lighting, high-rise buildings, airports, docks, CNC machinery and equipment, etc. Simply put, a dry-type transformer refers to a transformer in which the iron core and windings are not impregnated in insulating oil. The cooling methods are divided into natural air cooling and forced air cooling. When naturally air-cooled, the transformer can operate continuously for a long time at the rated capacity. When forced air-cooled, the output capacity of the transformer can be increased by 50%. It is suitable for intermittent overload operation or emergency accident overload operation; since the load loss and impedance voltage increase greatly during overload, it is in a non-economic operation state, so it should not be in long-term continuous overload operation.
