Draw-out type heat dissipation switch cabinet

Abstract

The invention discloses a draw-out type heat dissipation switch cabinet which comprises a switch cabinet body, an air inlet fan is fixedly connected to the bottom end of a fixed support, a rotating block is rotatably connected to the position, located at the top of the fixed support, of the inner side of an air inlet box, a sliding groove is formed in the inner side of the rotating block, and a filter screen is embedded into the inner side of the sliding groove. A magnetic strip is fixedly connected to the top end of the fixed support. The switch cabinet is scientific and reasonable in structure and safe and convenient to use, a large amount of air can be sucked into the switch cabinet through the air inlet fan, the air inlet fan and an exhaust fan work at the same time so that air flowing in the switch cabinet can be accelerated, the heat dissipation efficiency can be improved, a filter screen can filter the air during air inlet. And a phenomenon that a large amount of dust enters the switch cabinet and accumulates on the switch component to influence the normal use of the switch mechanical structure and further damage the switch component is avoided.

Description

technical field [0001] The invention relates to the technical field of switch cabinets, in particular to a draw-out heat dissipation switch cabinet. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs, such as instruments, automatic control, motor magnetic switches, various AC contactors, etc. Some also have high-voltage room and low-voltage room switchgear, high-voltage busbars, such as power plants, etc., and some also have low-cycle load shedding to ensure the main equipment. The main function of the switchgear is to generate electricity, transmit electricity, and In the process of power distribution and power conversion, open and close, control and protect electrical equipment. In order to facilitate the control of switch opening and closing, withdrawable switch cabine...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a withdrawable heat dissipation switchgear, which can effectively solve the problem that the existing withdrawable switchgear proposed in the above background technology not only has poor heat dissipation efficiency, but also The air inlet lacks a filter device, causing a large amount of dust to enter the switch cabinet, and a large amount of dust accumulates on the internal switch, resulting in damage to the switch and affecting the use of the switch cabinet
