Box-type substation shell possessing electromagnetic shielding function

Abstract

The invention discloses a box-type substation shell possessing an electromagnetic shielding function. The box-type substation shell comprises a steel underframe. A box body is arranged on the steel underframe. A cover plate is arranged on a top of the box body. Metal shielding nets are arranged in side plates of the box body and in the cover plate. The tops of the metal shielding nets in the side plates are connected with the metal shielding net in the cover plate. Bottoms of the metal shielding nets in the side plates are connected with the steel underframe. The metal shielding nets in the adjacent side plates of the box body are connected with each other. The metal shielding nets are arranged in the side plates and the cover plate of the box-type substation box body. The adjacent metal shielding nets are connected with each other. The bottoms of the metal shielding nets in the side plates of the box body are connected with the steel underframe so that the metal shielding nets form an enclosed shielding structure. Therefore, electromagnetic radiation generated by electrical equipment in the box-type substation box body can be effectively shielded. There is barely the electromagnetic radiation out of the substation box body. Physical health of surrounding personnel or safety operation of the surrounding electrical equipment can be effectively guaranteed.

Description

technical field [0001] The invention relates to a box-type substation, in particular to a box-type substation shell with an electromagnetic shielding function. Background technique [0002] Box-type substation is a kind of high-voltage switchgear, distribution transformer and low-voltage power distribution device. It is a factory prefabricated indoor and outdoor compact power distribution equipment arranged according to a certain wiring scheme. It is about high-voltage power receiving, transformer step-down, low-voltage distribution Electricity and other functions are organically combined and installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable box, mechanical and electrical integration, fully enclosed operation, especially suitable for Urban network construction and transformation is a brand-new substation emerging after the civil substation. [0003] The box-type substation is suitable for re...

AI Technical Summary

Problems solved by technology

[0006] However, this GRC material box-type substation box also has certain shortcomings. Since the box-type substation is equipped with electrical equipment such as transformers, these equipment often generate a large amount of electromagnetic radiation during operation.

In this way, when this box-type substation is installed in residential quarters, urban public substations, bustling downtown areas, etc., the radiation generated by electrical equipment may have adverse effects on people's health; when this box-type substation is installed in other electrical equipment If the box-type substation is installed around the track of the maglev train, the electromagnetic radiation generated by the electrical equipment in the box-type substation may affect the normal operation of the maglev train. possible safety incident

Similarly, the electrical equipment in the substation box is also susceptible to the influence of external electromagnetic radiation, which may also affect the normal operation of the electrical equipment in the substation box
