Movable heat dissipation opening overload protection type distribution transformer

Abstract

The invention discloses a movable heat dissipation opening overload protection type distribution transformer. The transformer structurally comprises a heat dissipation body, a supporting frame, a transformer main box body, an overload protector, a winding bushing group, an oil measuring cylinder and lifting lugs; and the supporting frame is arranged below a transformer main box body and is buckledto the transformer main box body. Most transformers are arranged in an outdoor working environment; a large amount of heat can be generated when transformer equipment operates; dust is easily accumulated on the surface of common corrugated radiating fins; outdoor high-altitude positions are inconvenient to clean frequently, after a long time, the heat dissipation functions of transformer main bodies can be directly affected, and the working efficiency of the transformer main bodies is reduced. The transformer of the invention is provided with a movable cooling fin mechanism, and therefore, when the transformer is used, dust accumulated on the surface of the transformer can be effectively shaken off, most of the dust falls off, and meanwhile, the heat dissipation performance of the transformer of the invention is better.

Description

technical field [0001] The invention relates to an overload-protected distribution transformer with a movable heat dissipation port, which belongs to the field of transformers. Background technique [0002] The transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. It is an important power equipment. Due to the coverage problem in some areas, the power grid will still be overloaded during use. Due to the long-term overload operation of the transformer, It will accelerate the aging of the insulation, reduce the service life of the transformer, or cause the transformer to burn out. Therefore, it is necessary to protect the transformer from overload in a specific area. [0003] The prior art has the following disadvantages: since the transformers are mostly set up in the outdoor working environment, the transformer equipment will generate a lot of heat during operation, and the surface of the general corrugated heat sink is easy t...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a distribution transformer with movable vent overload protection, so as to solve the problem that the existing transformers are mostly set up outdoors in the working environment, and the transformer equipment will generate a large amount of power during operation. The surface of the general corrugated heat sink is easy to accumulate dust, and it is inconvenient to clean it frequently in the outdoor high-altitude position. In the long run, it will directly affect the heat dissipation function of the main body of the transformer and reduce its working efficiency.
