Abstract

The invention discloses a switch cabinet pressure relief device capable of ventilating and preventing dust, comprising a sealing plate which comprises a top pate, four side plates connected with the top plate and a mounting plate used for arranging the sealing plate on the body of the switch cabinet; a plurality of sealing plate air vents are arranged at least one side plate; a dustproof chamber is tightly arranged on the inner wall of the side plate, and comprises a vertical baffle relative to the inner wall of the side plate; the vertical baffle is provided with a plurality of dustproof chamber air vents; and a labyrinth-type channel used for preventing the dust from directly entering the dustproof chamber air vent from the seal plate air vent is arranged in the dustproof chamber. By using the device provided by the invention, the problems that the dust can directly enter the switch cabinet, and the ventilating properties and the dustproof properties of the switch cabinet can be not simultaneously well dissolved; and the device is especially suitable for the ventilating and dustproof pressure relief device at the top part of the switch cabinet.

Description

technical field [0001] The invention relates to a switchgear pressure relief device, in particular to a ventilated and dustproof pressure relief device on the top of the switchgear. Background technique [0002] The switch cabinet is a kind of electrical equipment. The outside line first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. Since the electrical components in the switchgear will heat up during operation, the temperature and humidity in the switchgear will increase. In order to ensure the normal operation of the original components in the switchgear, the moisture in the switchgear needs to be discharged. The usual method is to add cooling vents to the cabinet body, but setting vent holes will reduce the protection level of the switch cabinet, and the dust from the external environment will easily enter the switch cabinet to form pollution, resulting in a decline in the performance of e...
