Problems solved by technology

[0002] A power transformer is an electrical device used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. It will generate a lot of heat, which needs to be dissipated in time to ensure the safety of use. The existing power transformer casing is equipped with heat sinks for heat dissipation, but when the power transformer is used outdoors, dirt is attached to the heat sink, resulting in poor heat dissipation of the transformer.

Abstract

The invention discloses a heat dissipation device for a power transformer, which relates to the technical field of power transformers. In order to solve the problem that the existing power transformer has poor heat dissipation effect due to dirt attached to the heat sink when it is used outdoors, it includes a transformer assembly, the transformer The assembly includes a transformer body located inside the housing and cooling fins on the outer wall of the housing, and the outer wall of the housing is installed with a base. When the present invention is in use, blow air to the heat sink through the fan to promote the air flow around the heat sink to ensure the heat dissipation effect. At the same time, the air flow blows the first arc-shaped part and the dust scraping mechanism upwards, so that the dust scraping mechanism moves vertically to the side of the heat sink. Scraping is carried out, and the reciprocating blocking of the air vent by the blocking part makes the first arc-shaped part and the ash scraping mechanism move downward due to the action of gravity when the air vent is blocked, so as to realize the reciprocating scraping of the side of the heat sink, ensuring the scraping The effect is better, and the heat dissipation effect on the shell is improved.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to a heat dissipation device for power transformers. Background technique [0002] A power transformer is an electrical device used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values. It will generate a lot of heat, which needs to be dissipated in time to ensure the safety of use. The existing power transformer casing is equipped with heat sinks for heat dissipation, but when the power transformer is used outdoors, dirt is attached to the heat sink, resulting in poor heat dissipation of the transformer. Case. Contents of the invention [0003] The purpose of the present invention is to solve the shortcomings in the prior art, and propose a power transformer cooling device. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: ...
