Dust cover for electric power information switch

Abstract

The invention relates to a dust cover for an electric power information switch.The dust cover is arranged at an air inlet of the electric power information switch.The dust cover for the electric power information switch comprises a housing and a plurality of layers of dust meshes, wherein a ventilation channel is formed inside the housing, and the dust meshes are arranged inside the housing, cover the section of the ventilation channel and are provided with filter holes.The outer end of the ventilation channel is connected with the external world.The inner end of the ventilation channel is connected with the air inlet.The hole diameters of the filter holes in the dust meshes are different.According to the dust cover, dust entering the switch can be effectively filtered, so that the influence caused by dust accumulation at a fan is avoided, and the influence caused on components inside the switch when dust enters the switch is also avoided.The dust cover is rapid and convenient to use and capable of saving time and labor, the service life of the fan of the switch can be greatly prolonged through the dust cover, the working stability of the switch is greatly improved, and the working years of the switch are prolonged.

Description

technical field [0001] The invention relates to a dustproof cover applied to a power information exchange. Background technique [0002] The power information switch in the power system uses a fan to cool down the temperature. Because the working environment of some switches is dusty, after a long period of use, a large amount of dust will accumulate at the air inlet of the fan, which makes the working effect of the fan worse. Worse or even stop working, which will increase the internal temperature of the switch and affect the normal work, and the fan will inhale dust when it is working, causing damage to the switch. Usually, the switch needs to be cleaned regularly. At this time, not only the switch needs to be shut down, but also the disassembly and assembly of the switch is very troublesome, time-consuming and laborious, and the efficiency is low. Contents of the invention [0003] The purpose of the present invention is to provide a dustproof cover for an electric pow...
