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, and the cooling methods are divided into natural air cooling (AN) and forced air cooling (AF). 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 device is suitable for intermittent overload operation or emergency accident overload operation; because the load loss and the impedance voltage amplification are large during overload and the device is in a non-economic operation state, the device is not required to be in continuous overload operation for a long time.

However, the existing dry-type transformer cooling structure has some defects in the use process, a heat dissipation hole is simply formed to dissipate heat, or a fan is arranged to accelerate the air flow rate to dissipate heat, the heat dissipation efficiency is low, and then the heat dissipation structure is simple, single in function and fixed and troublesome, so that the requirements of users cannot be met.
