Abstract

The invention provides an electrical switch mounting assembly controlled by air pressure and used for a power distribution cabinet. The electrical switch mounting assembly comprises a mounting plate (28) which is fixed on a side wall of a cabinet body (2) of the power distribution cabinet through a fastening device (280) and is used for mounting an electrical switch for power distribution, an electrical switch (22) which is mounted on the mounting plate (28) and needs to be cooled, and a cooling device for cooling the electrical switch needing to be cooled; and the cooling device comprises a fixed bearing barrel (9) which is fixedly mounted on the mounting plate (28), is arranged around the electrical switch needing to be cooled, and is provided with a ventilation opening (91) at the bottom.

Description

technical field [0001] This application relates to the field of power distribution cabinets, in particular to an electrical switch installation assembly for a power distribution cabinet controlled by air pressure. 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 object of the present invention is to provide an electrical switch in...
