High-voltage switch cabinet structure

Abstract

The invention discloses a high-voltage switch cabinet structure. The power distribution cabinet comprises a cabinet body, a bus chamber, a cable chamber and a circuit breaker chamber are arranged in the cabinet body. The circuit breaker chamber is separated from the bus chamber and the cable chamber through a safety separator plate. The bus chamber is separated from the cable chamber through a bent plate, a three-phase circuit breaker is installed in the circuit breaker chamber, a busbar is installed in the bus chamber, a current transformer, a lightning arrester and a grounding switch are installed in the cable chamber, the current transformer is inversely installed below the bent plate, and the lightning arrester and the grounding switch are installed on the safety partition plate. According to the high-voltage switch cabinet structure, the current transformer and the grounding switch can be conveniently overhauled.

Description

technical field [0001] The invention relates to the field of switch cabinets, in particular to a high-voltage switch cabinet structure. Background technique [0002] Cooperate figure 1 and figure 2 As shown, the following problems exist in the existing high-voltage switchgear: [0003] 1. The current transformer 1' and the grounding switch 2' in the cable room A of the switch cabinet are installed at the back of the cabinet, occupying most of the space at the back of the cabinet; the installation positions of the current transformer and the grounding switch increase The installation of components is difficult, and it is not conducive to on-site operation and later maintenance of current transformers and grounding switches; [0004] 2. The cabinet body of the switchgear adopts a stepped structure, and the bus bar 3' of the bus bar room B on the top of the cabinet body adopts an L-shaped arrangement, resulting in a narrow space in the bus bar room B, which is not conducive...

Problems solved by technology

[0003] 1. The current transformer 1' and the grounding switch 2' in the cable room A of the switch cabinet are installed at the back of the cabinet, occupying most of the space at the back of the cabinet; the installation positions of the current transformer and the grounding switch increase The installation of components is difficult, and it is not conducive to on-site operation and later maintenance of current transformers and grounding switches;

[0004] 2. The cabinet body of the switchgear adopts a stepped structure, and the bus bar 3' of the bus bar room B on the top of the cabinet body adopts an L-shaped arrangement, resulting in a narrow space in the bus bar room B, which is not conducive to the heat dissipation of the bus bar copper bars, and affects the electrical conductivity of the bus bar copper bars
