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
The present invention relates to the switch cubicle explosion-proof technology.
Background technology
Switch cubicle often produces arc fault because of it is inner and explodes, and existing switch cubicle pressure relief device structure is that trip bolt directly is fastened on switch cubicle top sealing plate or the side seal board, after use metallic screw instead nylon screw and replace.When the inner generation of switch cubicle arc fault, thrust nylon screw and pressure release by blast.This structure assembling is cumbersome, and standardization and versatility are poor.The pressure-relief explosion-proof poor performance is operated safe and reliable inadequately.
Summary of the invention
For overcoming the defective that existing technology exists, the invention provides a kind of decompression anti-explosion device for switch cabinet, it can improve pressure release, and is explosion-proof effectively, improves handling safety.
The present invention realizes by following technical scheme, it comprises shrouding, its structural feature is that shrouding is provided with a hole, be provided with two bursting diaphragms in the hole, cross surface is by rivet together mutually for two bursting diaphragms and shrouding, a bursting diaphragm folding surface concora crush between two crossing bursting diaphragms is on another bursting diaphragm, and the bond end of this bursting diaphragm folding surface is riveted by rivet mutually with another bursting diaphragm.
Be evenly equipped with rectangular recess on above-mentioned two bursting diaphragm planes that are positioned at riveted joint place of nearly shrouding.
The present invention is provided with bursting diaphragm owing to perforate on the shrouding, and shrouding is installed in the top or the side of switch cubicle again, energy standardization like this, normalization, producing in serial form shrouding, versatility degree height.Perforate does not influence the structural strength of shrouding and switch cubicle on shrouding, has improved the pressure-relief explosion-proof performance.Be processed with rectangular recess on the bursting diaphragm, explosion time makes this place's bursting diaphragm complications easily, is convenient to explosion gas and discharges, and avoids operational hazards, can be safe and reliable.
Description of drawings
Below with reference to drawings and Examples invention is further described.
Fig. 1 is a structural representation of the present invention.
Fig. 2 is shrouding of the present invention and bursting diaphragm riveted joint figure.
Fig. 3 is bursting diaphragm of the present invention and bursting diaphragm riveted joint figure.
Embodiment
See Fig. 1, Fig. 2 and Fig. 3, shrouding 1 is installed in the top or the side of switch cubicle, and the middle part of shrouding 1 has big slot, in order to bursting diaphragm 2 and 4 to be installed.Bursting diaphragm 2 and 4 and shrouding 1 intersection is riveted bursting diaphragm 2 with shrouding 1 with 4 respectively mutually with rivet 3.The middle intersection of bursting diaphragm 2 and bursting diaphragm 4, on bursting diaphragm 4, the bond end of this folding surface is riveted mutually with bursting diaphragm 4 usefulness rivets 3 with bursting diaphragm 2 folding surface concora crush.There is not the gap between bursting diaphragm and the shrouding like this, on bursting diaphragm 2 and 4 and near processing and be evenly equipped with rectangular recess 5 with shrouding 1 riveted joint place.When the inner generation of switch cubicle arcing fault, because bursting diaphragm 2 bond ends are that semicircle orifice and bursting diaphragm 4 are riveted together, damp is easy to break through this explosion-protection equipment and pressure release.Owing to have rectangular recess 5 on bursting diaphragm 2 and 4 planes, when blast takes place, bursting diaphragm 2 and 4 can overcome easily the bond end rivet pressing friction power and upwards complications dig, explosion gas is discharged, guarantee that handling safety is reliable.
Claims (2)
1. decompression anti-explosion device for switch cabinet, comprise shrouding, it is characterized in that shrouding is provided with a hole, be provided with two bursting diaphragms in the hole, cross surface is by rivet together mutually for two bursting diaphragms and shrouding, a bursting diaphragm folding surface concora crush between two crossing bursting diaphragms is on another bursting diaphragm, and the bond end of this bursting diaphragm folding surface is riveted by rivet mutually with another bursting diaphragm.
2. a kind of decompression anti-explosion device according to claim 1 is characterized in that being positioned on two bursting diaphragm planes of nearly shrouding riveted joint place and is evenly equipped with rectangular recess.
