Embodiment Construction

[0011] See figure 1 , Figure 2 and image 3 , The sealing plate 1 is installed on the top or side of the switch cabinet, and the middle part of the sealing plate 1 has a large rectangular hole for installing the explosion-proof plates 2 and 4. At the intersection of the explosion-proof plates 2 and 4 and the sealing plate 1, use rivets 3 to rivet the explosion-proof plates 2 and 4 and the sealing plate 1 respectively. At the middle intersection of the explosion-proof plate 2 and the explosion-proof plate 4, the bending surface of the explosion-proof plate 2 is flatly pressed on the explosion-proof plate 4, and the overlapping end of the bending surface and the explosion-proof plate 4 are riveted with rivets 3. There is no gap between the explosion-proof plate and the sealing plate like this, and rectangular grooves 5 are evenly distributed on the explosion-proof plates 2 and 4 and are processed near the riveting place with the sealing plate 1 . When an arcing fault occurs in...

Abstract

This invented pressure-releasing, explosion-proof means for switch-cubicle is characterized by that it is a sealing board having a window with two explosion-proof plates in it. The sealing board can be placed on the top or one side of the switch-cubicle. Riveting method is used between explosion-proof plate and next explosion plate, and explosion-proof plate and sealing board. This invented means has advantages: explosion gas is released easily, and it is safety and reliable.

Description

technical field [0001] The invention relates to the explosion-proof technology of a switch cabinet. Background technique [0002] The switchgear often explodes due to an arc fault inside the switchgear. The existing structure of the pressure relief device for the switchgear is to directly fasten the fastening screws on the top sealing plate or side sealing plate of the switchgear, and then replace the metal screws with nylon screws. . When an arc fault occurs inside the switchgear, the nylon screw is blown off by explosion to release the pressure. This kind of structural assembly is cumbersome, and the standardization and versatility are poor. The pressure relief and explosion-proof performance is poor, and the operation is not safe and reliable enough. Contents of the invention [0003] In order to overcome the defects existing in the prior art, the present invention provides a pressure relief and explosion-proof device for a switchgear, which can improve pressure reli...
