Dustproof heat dissipation system of switch cabinet

Abstract

The invention relates to a dustproof heat dissipation system of a switch cabinet, which comprises a cabinet body and a cabinet door of the switch cabinet, wherein the cabinet body is hinged with the cabinet door, a cold air device is arranged on the cabinet body, and a controller for controlling the cold air device is also arranged in the cabinet body, wherein a cooling pipe is vertically arrangedat the middle position of the cabinet body, the pipe body of the cooling pipe is spiral, the cross section of the cooling pipe is semicircular, an air inlet and an air outlet are formed in the cabinet body, one end of the air inlet is connected with the upper end of the cooling pipe, the other end of the air inlet is connected with the cold air device, and the air outlet is located at the middleposition of the lower side wall of the cabinet body. The scheme adopts the arrangement of the spiral cooling pipe in the cabinet body, which can simultaneously carry out cooling and dust removal actions, and the dustproof heat dissipation system of the switch cabinet has the advantages of simple structure, high cooling efficiency, low energy consumption and the like, and has strong practicability.

Description

technical field [0001] The invention relates to the field of dust prevention and heat dissipation of electric facilities, in particular to a dust prevention and heat dissipation system of a switch cabinet. Background technique [0002] High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as electrical products with a voltage level of 3.6kV~550kV, and high-voltage isolating switches With grounding switch, high-voltage load switch, high-voltage automatic reclosing and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear, etc., the existing high-voltage switchgear often has excessive temperature in the box during use. In the case of high temperature, the current main solution to the high temperature problem is to achieve the purpose of cooling by addin...

Problems solved by technology

This solution can achieve the purpose of heat dissipation through the setting of the cooling fan on the top, but in actual use, it can only cool down the device directly below the cooling fan, and the inside of the cabinet is usually still in a high temperature state. In this solution, each vent is also set There is a dust-proof net to achieve the dust-proof effect, but the floating dust entering during the switching process is difficult to discharge, and there are still hidden dangers, and the actual use effect is not good
