Background
Dry transformers are widely used in places such as local lighting, high-rise buildings, airports, wharf CNC mechanical equipment and the like, and simply said dry transformers refer to transformers in which the iron cores and windings are not immersed in insulating oil. The cooling modes are classified into natural air cooling and forced air cooling. During natural air cooling, the transformer can continuously operate for a long time under rated capacity. When forced air cooling is performed, the output capacity of the transformer can be improved by 50%. The method is suitable for intermittent overload operation or emergency accident overload operation. The overload load loss and the impedance voltage increase are large in overload, and are in uneconomical operation states, so that the overload load is not continuously in overload operation for a long time.
