A box-type substation box body and its top cover

Abstract

The invention relates to a box-type transformer substation box and a top cover thereof, the top cover includes a top cover frame, and a fully enclosed outer cover plate arranged on the top cover frame, The lower side of the outer cover plate is provided with a heat dissipation channel plate, and a heat dissipation channel is formed between the heat dissipation channel plate and the outer cover plate. The heat dissipation channel is provided with an air inlet for communicating with the inside of the box-type substation box body, and the heat dissipation channel is further provided with an air outlet for communicating with the outside, which is located at the edge of the top cover and opens downward. In this invention, the air outlet of the heat dissipation channel is located at the edge ofthe top cover, Without affecting the installation of the top cover, The heat dissipation channel is communicated with the outside of the box-type substation, and the opening of the air outlet is downward, the air in the box body of the box-type substation is discharged downward from the air outlet, and the rainwater outside the box body does not enter into the box-type substation from the air outlet, so that the protection level of the box body of the box-type substation is improved without affecting the heat dissipation effect.

Description

technical field [0001] The invention relates to a box-type substation box body and its top cover. Background technique [0002] The box-type substation is a compact combined outdoor power transmission and distribution equipment integrating transformers, high-voltage switchgear and other electrical components. It has relatively high requirements for operational safety, reliability and protection level. With the development of the electric power industry, the capacity of the box-type substation is getting larger and larger, and the electrical components in the substation, such as transformers, have higher and higher calorific value, which requires the box-type substation to have a sufficiently high protection level. , but also have good heat dissipation performance. The box-type substation box mainly includes a base, a shell, and a top cover. The design of the top cover determines the heat dissipation performance of the box-type substation box. [0003] The Chinese utility m...
