Box-type transformer-station double-layer top cover structure

Abstract

The invention discloses a top cover structure of a box-type substation, which has a simple structure and strong heat dissipation capability. It is a double-layer top cover structure of a box-type substation including a large top cover and a small top cover. The middle part of the large top cover is provided with a The small top cover is fixed above the through hole and there is an air passage between the large top cover; the air passage facilitates the air circulation inside and outside the box-type substation to ensure a certain heat dissipation performance. In addition, due to the air The channel is located on the top of the box-type substation, and a large temperature difference is formed in the substation in the height direction, thereby generating a difference in air pressure, forming a strong convection, and increasing the heat dissipation capacity of the box-type substation.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to a top cover structure of a box-type substation. Background technique [0002] The box-type substation is a factory prefabricated indoor and outdoor compact power distribution equipment, which organically combines functions such as high-voltage power receiving, transformer step-down, and low-voltage power distribution, and is installed in a moisture-proof, rust-proof, dust-proof, and Rat, fire prevention, anti-theft, heat insulation, fully enclosed, movable steel structure box, mechanical and electrical integration, a brand new substation with fully enclosed operation. The transformer is an indispensable device in the box-type substation, and it is also the main heating device. However, the working life of the transformer is greatly affected by the temperature. Long-term high temperature will shorten the life of the transformer. On the basis of heat dissipation in the transformer...

AI Technical Summary

Problems solved by technology

The transformer is an indispensable device in the box-type substation, and it is also the main heating device. However, the working life of the transformer is greatly affected by the temperature. Long-term high temperature will shorten the life of the transformer. On the basis of heat dissipation in the transformer, a box-type substation is also required. The substation has better ventilation and heat dissipation conditions; in addition, the heat dissipation of the existing box-type substation box is mainly through the ventilation holes of the outer box wall and the top cover, but the current top cover structure has poor heat dissipation capacity, resulting in internal components of the box-type substation.
