Detailed description of the invention
The enforcement of switch cubicle is such as shown in Fig. 1 ~ 6: the switch cubicle in the present embodiment is high-tension switch cabinet, including cabinet (figure
Not shown in) and pressure relief device, pressure relief device includes substrate 1 and shrouding 2, and wherein substrate 1 is fixed on the top board at cabinet top,
Substrate includes the substrate body being provided with pressure relief opening 7, the crisscross demarcation strip that pressure relief opening 7 is wholely set with substrate body
6 are separated into multiple grid hole structure.Shrouding include being arranged at the one end at pressure relief opening be connect end, the other end is the envelope of free end
Plate body, substrate body is provided with three edges and is perpendicular to the guiding elongated slot 8 that substrate thickness of slab direction extends, defined in the present embodiment
The guide direction guiding elongated slot 8 is left and right directions, and substrate thickness of slab direction is fore-and-aft direction, and each elongated slot 8 that guides is along guiding elongated slot
Guide direction interval is arranged, the end that connects of shrouding body is provided with the connection flange 9 corresponding with guiding elongated slot number, connects flange
9 can be along the thickness of slab direction of substrate by passing corresponding guiding elongated slot 8 outside cabinet, the right-hand member connecting flange 9 is provided with draw-in groove
10, when exerting a force to shrouding, connecting flange can move, until substrate body snaps onto draw-in groove along the guide direction guiding elongated slot
In 10, connection flange 9 hook formed just hooks substrate body, guides the right side cell wall of elongated slot and the bottom land gear of draw-in groove 10
Only coordinate, shrouding and can not continue to move to, now the cell wall of draw-in groove coordinates with the plate face block of substrate body and limits shrouding and exist
Overturn time not by external force.
The upper end of pressure relief opening is provided with gap 10, and the free end of shrouding body is wholely set the court corresponding with gap number
To connecting the elastic bending limit 5 that flange side bends, coordinate with the bottom land block of draw-in groove at the side cell wall guiding elongated slot
Time, elastic bending limit 5 also can snap onto in the gap 10 of correspondence, thus limit shrouding and move along guiding elongated slot guide direction.Bullet
Having, between both sides and the shrouding body of property curved edges 5, the gap cut out by line laser, this gap is conducive to improving elasticity
The pliability of curved edges, thus reduce pressure release resistance, it is ensured that when occurring arcing fault in switch cubicle, elastic bending limit can be suitable
Profit deformation and gap disengage without hindering shrouding deformation, and gap is formed by cut, it is possible to the effective width reducing gap
Degree, improves degree of protection.Being provided with platoon leader's square opening 4 by connection flange on shrouding plate body, this platoon leader's square opening 4 is by substrate
Body stops the degree of protection without reducing switch cubicle, and this platoon leader's square opening forms the weak spot of shrouding, prevents shrouding by card
The most in particular cases, shrouding is guided to select to open along this weak spot under the impact of air pressure.Shrouding body is each side
Having one section of flanging 3, shrouding is operated by convenience hands or instrument, adds flatness and the intensity of shrouding simultaneously.
During use, by shrouding connect flange outside cabinet from outside to inside be inserted into correspondence guiding elongated slot,
Then promoting shrouding to make the connection flange of shrouding move right along guiding elongated slot, until pushing away motionless, now guiding the cell wall of elongated slot
Coordinating with the bottom land block of draw-in groove, substrate body snaps in draw-in groove, and shrouding is just tightly secured on substrate, promotes shrouding to opposite direction
Then can be taken off by substrate by shrouding, the installation of shrouding is very convenient；Elastic bending limit and shrouding body form certain folder
Angle, while shrouding moves into place, elastic bending limit also snaps in corresponding gap, thus shrouding is restricted to locked position,
Prevent shrouding from moving left and right, additionally also there is between elastic bending limit and substrate certain elastic acting force, it is ensured that shrouding will not
It is opened easily.When the pressure in cabinet opens shrouding, connection flange the hook formed can tightly hang on substrate,
Shrouding is not caused to be come off and crisis equipment and the safety of the person by switch cubicle；The demarcation strip separating pressure relief opening can increase pressure release
The structural strength that mouth goes out, it is ensured that the size of pressure relief opening can be done greatly as far as possible.
In other embodiments of the invention: the gap between elastic bending limit and shrouding body can not also set；Certainly,
When the frictional force connected between flange and guiding elongated slot is relatively big, and when shrouding is difficult to move left and right, elastic bending limit can not also set；
The demarcation strip separating pressure relief opening can not also set；The number guiding elongated slot can also be configured as required, such as one,
Two or other number；Substrate can also be wholely set with the top board of cabinet；Pressure relief device can also be arranged at the side plate of cabinet
On；Switch cubicle can also be low pressure or Medium Voltage Switchgear.
The enforcement of pressure relief device is such as shown in Fig. 1 ~ 6: in the concrete structure of pressure relief device and above-mentioned each switch cubicle embodiment
Described pressure relief device is identical, is not described in detail in this.
The enforcement of the shrouding of pressure relief device is such as shown in Fig. 1 ~ 6: the concrete structure of the shrouding of pressure relief device is respectively opened with above-mentioned
Close the shrouding described in cabinet embodiment identical, be not described in detail in this.
The enforcement of the substrate of pressure relief device is such as shown in Fig. 1 ~ 6: the concrete structure of the substrate of pressure relief device is respectively opened with above-mentioned
Close the substrate described in cabinet embodiment identical, be not described in detail in this.
