Background

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, etc., and simply, dry-type transformers refer to transformers in which the iron core and windings are not immersed in insulating oil. The cooling method is divided into natural air cooling and forced air cooling. During natural air cooling, the transformer can continuously operate for a long time under the rated capacity. When forced air cooling is carried out, the output capacity of the transformer can be improved by fifty percent. The overload protection circuit is suitable for intermittent overload operation or emergency accident overload operation, and the overload protection circuit is in a non-economic operation state due to large load loss and impedance voltage amplification during overload, so that the overload protection circuit is not required to be in long-time continuous overload operation. The dry type transformer is mainly composed of an iron core composed of silicon steel sheets and coils poured by epoxy resin, an insulating cylinder is arranged between the high-voltage coils and the low-voltage coils to increase electrical insulation, the coils are supported and restrained by cushion blocks, and fasteners lapped by parts of the coils have anti-loosening performance.
