Electric switch installation assembly

Abstract

An electric switch installation assembly comprises an installation plate (28) which is fixed on a side wall of a cabinet body (2) of a power distribution cabinet through fastening members (280) and is used for installing electric switches used for power distribution, the electric switches (22) installed on the installation plate (28) and needing to be cooled, and a cooling device used for cooling the electric switches needing to be cooled. The cooling device comprises a fixed bearing cylinder (9), wherein the fixed bearing cylinder is fixedly installed on the installation plate (28) and surrounds the electric switches needing to be cooled, and the bottom part of the fixed bearing cylinder is provided with ventilation openings (91).

Description

technical field

[0001] This application relates to the field of power distribution cabinets, specifically an electrical switch installation assembly. Background technique

[0002] There are usually various electrical switching elements in the distribution cabinet. In these electrical components, the heat generation and heat dissipation are the same, especially for the main switch. For the entire power distribution cabinet, its safety and stability often depend on the position or point where the heat generation of the main switch is the highest. Conventional heat dissipation methods often use exhaust fans and dedicated heat dissipation fans, etc., but it is difficult to dissipate heat or cool down the heat accumulation area or single / multiple heat in the power distribution cabinet in a targeted manner. Contents of the invention

[0003] The purpose of the present invention is to provide an electrical switch installation assembly, which can overcome the defects in the prio...
