Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a box-type transformer. Background Art

[0002] The box-type transformer is a highly integrated power equipment. It is mainly composed of high-voltage switches, transformers and low-voltage distribution devices integrated in a compact unit according to a specific wiring scheme. These devices are installed in a steel structure box. Transformers and other equipment will generate a lot of heat when working. In order to avoid heat accumulation in the box, shutters are usually installed for heat dissipation.

[0003] When existing box-type transformers encounter strong winds and rain, rainwater will enter the box through the blinds under the action of wind, causing the insulation performance inside the box to deteriorate, increasing the risk of short circuit or leakage inside the transformer, and possibly causing electrical failure or fire. In addition, in cold weather, the warm environment inside the box will attract small animals, which will enter the box through the blinds and may cause short circuit and other faults in the transformer, making it unsafe.
