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. Easily damaged by overheating

Embodiment Construction

[0016] refer to Figure 1 to Figure 3 , a box-type substation double-layer roof structure of the present invention, comprising a large roof 1 and a small roof 2, the middle of the large roof 1 is provided with a through hole, and the through hole is provided with a ventilation screen, The small top cover 2 is fixed on the top of the big top cover 1 and covers the ventilating screen, an air passage is left between the small top cover 2 and the big top cover 1, and a small top cover 2 is arranged below the edge of the small top cover 2. Hole plate 3 to prevent foreign matter from entering the box-type substation from the air channel. The air channel facilitates the air circulation inside and outside the box-type substation and ensures a certain heat dissipation performance. In addition, since the air channel is located on the top of the box-type substation, a large temperature difference is formed in the substation in the height direction, thereby generating an air pressure diff...

Abstract

The invention discloses a box-type transformer-station double-layer top cover structure. The structure is simple, the heat dissipation capability is high, and the box-type transformer-station double-layer top cover structure includes a big top cover and a small top cover; the middle of the big top cover is provided with a through hole, the small top cover is fixed above the through hole, and an air channel is left between the small top cover and the big top cover; the air channel is beneficial to air circulation inside and outside a box-type transformer station, and certain heat dissipation performance is ensured. Moreover, since the air channel is formed in the top of the box-type transformer station, large temperature difference is formed in the transformer station in the height direction, air pressure difference is thus formed, strong convection is formed, and the heat dissipation capacity of the box-type transformer station is improved.

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...
