Air-cooling heat dissipation guide device for corrugated tank of transformer

Abstract

The invention discloses an air-cooling heat dissipation guide device for a corrugated tank of a transformer. The air-cooling dissipation guide device comprises a fencing board, tooth slices and a fan; the tooth slices are arranged at four sides of the corrugated tank of the transformer and engaged with the corrugated sheet of the transformer, and a gap is arranged between the tooth slices and the corrugated sheet of the transformer; the fencing board is arranged outside the tooth slices; the fan is installed at the bottom of the corrugated tank of the transformer and faces towards the corrugated sheet of the transformer in the fencing board; and an exhaust port is arranged on the top of the corrugated tank of the transformer. In the invention, the fan is arranged at the bottom of the transformer and blows towards the corrugated sheet of the transformer, and hot wind is guided out from the upper part of the transformer, thus rapidly bringing out heat, achieving good heat dissipation effect and prolonging the service life of the transformer.

Description

technical field [0001] The invention belongs to the field of transformers, in particular to an air-cooled and heat-dissipating guide device for a corrugated oil tank of a transformer that operates in a box-type substation and a closed room with limited transformer volume. Background technique [0002] At present, oil-immersed distribution transformers have all been changed from traditional tube heat dissipation to corrugated sheet heat dissipation. That is, it is folded from a thin steel plate into a multi-piece corrugated wing-shaped box wall and welded into a fuel tank, which is called a corrugated fuel tank. Some of these transformers are installed in sealed box-type substations, and some are installed in the engine room of large cranes and dust removal equipment, and the heat dissipation of the transformer is greatly affected. The measure that generally takes now is to install exhaust fan cooling on the substation and the top of the engine room, but the effect of this c...

AI Technical Summary

Problems solved by technology

[0003] In order to overcome the problem of poor heat dissipation effect in the prior art, the object of the present invention is to provide an air-cooled heat dissipation guide device for a transformer corrugated oil tank. The upper part is exported to quickly take out the heat, and the heat dissipation effect is good, which prolongs the service life of the transformer
