Background

Dry-type transformers are widely used in local lighting, high-rise buildings, airports, wharf CNC machines and other places, and simply, dry-type transformers refer to transformers in which iron cores 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 50 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.

Dry-type transformer among the prior art places through a backup pad mostly, has first long-term operation, and the transformer can vibrate, can lead to the life of transformer to reduce, and in addition, the in-process of support lacks spacing structure, leads to the supporting effect poor.
