Embodiment Construction

[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0018] see figure 1 , an explosion-proof device for an inflatable switchgear, is an explosion-proof device installed on an air chamber.

[0019] A pressure release port is provided on the top or bottom of the air chamber of the inflatable switchgear, and the pressure release port is rectangular. An explosion-proof membrane support 4 is installed on the pressure release port, and the explosion-proof membrane support 4 is composed of a frame 41 and a blocking strip 42 . The frame 41 of the explosion-proof membrane support 4 is arranged on the pressure release port, and the blocking strip 42 is arranged on the frame 41 and blocks the frame port of the frame 41 . (see figure 2 )

[0020] The sealing ring 2 is placed on the outside of the explosio...

Abstract

The invention relates to anexplosion-proof equipment, particularly to an explosion-proof equipment for charging the air chamber of the switchboard. The explosion-proof equipment of the charging switchboard includes a rupture membrane frame, comprising a frame and a blocked side of the partition frame port arranged on the frame, wherein a pressure release port is arranged on the air chamber of the charging switch and the frame is arranged on the pressure release port; a sealing ring, arranged on the outside of the rupture membrane frame and the circumference of the pressure release port; a rupture membrane, arranged on the sealing ring for sealing the frame port of the frame; a pressboard, fastened on the circumference of the pressure release port for fastening the rupture membrane and the sealing ring on the circumference of the pressure release port. The device can prevent the explosion accident of the air chamber when the air in the air chamber of the charging switchboard releases with certain pressure.

Description

technical field [0001] The invention relates to an explosion-proof device, in particular to an explosion-proof device for an air chamber of an inflatable switchgear, which can prevent the pressure in the air chamber from accidentally rising and causing explosion. Background technique [0002] In the inflatable switchgear in operation, when the sealed gas chamber is under some unexpected circumstances (such as short circuit of high-voltage components or abnormal local heating), the gas pressure in the gas chamber suddenly rises, far exceeding the pressure that the gas chamber can normally withstand, and the There is a possibility of exploding the cell, destroying it, and causing personal injury to personnel performing maintenance. Therefore, there is a need for a device that can effectively reduce the gas pressure in the gas chamber in time when an accident occurs, so that the gas pressure will not exceed the pressure when the gas chamber is damaged, thereby ensuring the safe...
