Description
Technical field
Switch cubicle technical field is the utility model is related to, in particular, it is related to a kind of back door structure of switch cubicle.
Background technology
In recent years, market requires more and more higher for the security performance of switch cubicle, and internal arcing failure is to security
The ultimate challenge of energy.Because rear cable vault's pressure release passage of switch cubicle is more narrow compared to other compartment pressure release passages, therefore
During the internal arcing failure of generation, the intensity and protective capacities of back door structure are particularly significant.Back door structure in the market is to anti-
The ability that only high-temperature gas and electric arc spray is weaker, and the personnel after cabinet or equipment are caused when easily internally arcing failure occurs
Injury.
The content of the invention
The utility model overcomes the deficiencies in the prior art, there is provided a kind of intensity is good, can effectively prevent high-temperature gas and
A kind of back door structure for switch cubicle that electric arc sprays.
In order to solve the above-mentioned technical problem, the technical solution of the utility model is as follows：
A kind of back door structure of switch cubicle, including upper sealing plate, lower shrouding, side plate, interior crossbeam and outer crossbeam；The upper sealing plate
With welding reinforcement on the inside of lower shrouding, the reinforcement quantity is highly adjusted and is uniformly distributed with door-plate, on the reinforcement
Digital and analog hole is opened up, interior lining panel is set on the inside of the lower shrouding, and interior lining panel sets liner plate waist hole in digital and analog hole corresponding position, and leads to
Screw is crossed to be fastened；The lower shrouding centre position sets observation window, and interior lining panel corresponds to observation window opening position and sets square hole；Institute
State and upper hem is set above lower shrouding, lower hem is set below the upper sealing plate, upper hem is pressed on lower hem；The upper envelope
Plate, lower shrouding surrounding set " bow " type bending edges, should set waist hole on " bow " type bending edges, and be bolted on side plate with
On outer crossbeam, the interior crossbeam is arranged on outer cross rail inner, and interior crossbeam, outer crossbeam correspond to the waist hole position of upper hem and lower hem
Place sets mounting hole, is fastened together by bolt and riveting nut.
Further, the side plate is provided with side plate column, and the upper sealing plate, lower shrouding are bonded with heel post.
Further, the upper sealing plate, the side of lower shrouding set and are hingedly connected on side plate column.
Further, fixed setting right baffle-plate, right shell body on the inside of the side plate column, and stretch into lower shrouding and interior lining panel
In fit-up gap.
Further, the outer crossbeam both ends are fixed on side plate.
Advantage is the utility model compared with prior art：
The utility model structure design is simple, reasonable, easy to make, practical, easily promotes the use of.The utility model
Using connecting lining plate, lower shrouding can be fixed well for this, than the mode such as bolt, rivet that uses at present of use have more
Fixed effect well, according to its anti-deformation intensity is contrasted much stronger than bolt or rivet, its sealing effect is even more a world of difference,
Arcing will not produce leakage completely when occurring, and will not more produce gap.Substituted for it is currently used in order to ensure its sealing, and
The sealing ring added, but in the environment of this high pressure high current of switch cubicle, use the sealing that will gasify after a period of time
Circle considerably increases cost, it is necessary to frequently repaired by staff.And this programme is then completely worried without this, significantly
Maintenance cost is reduced, improves safety coefficient.

Embodiment
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
As shown in Figures 1 to 5, a kind of back door structure of switch cubicle, including upper sealing plate 1, lower shrouding 2, interior crossbeam 8 and outer horizontal stroke
Beam 9.
The upper sealing plate 1 and the inner side of lower shrouding 2 weldering reinforcement 4, the quantity of reinforcement 4 highly adjust and uniform with door-plate
Distribution, digital and analog hole 5 is opened up on the reinforcement 4.The lower inner side of shrouding 2 installation interior lining panel 6, the corresponding position of digital and analog hole 5 of interior lining panel 6
Liner plate waist hole 7 is opened up, and is fastened by screw.Lower shrouding centre position sets observation window 12, for component in cabinet
Observed, the corresponding position of observation window 12 of interior lining panel 6 sets square hole.Upper sealing plate 1, the surrounding of lower shrouding 2 are " bow " type bending edges 16
Structure, the lower section of upper sealing plate 1 is lower hem 15, is upper hem 14 above lower shrouding.
At closing time, the upper hem 14 of the lower shrouding 2 is pressed at the lower hem 15 of upper sealing plate 1, and realization is switched on lower envelope
Plate 2 could open upper sealing plate 1, meet switch cubicle rear portion gate interlock up and down.The upper sealing plate 1, lower shrouding 2 and the side on side plate 3
Plate column 17 is bonded.Upper sealing plate 1, the side of lower shrouding 2 are connected on side plate column 17 by hinge 13, are opened on " bow " type bending edges 16
Waist hole is bolted on side plate 3 and outer crossbeam 9.The outer both ends of crossbeam 9 are fixed on side plate 3, and its inner side has set reinforcement
The interior crossbeam 8 of effect, the corresponding upper hem 14 of interior crossbeam 8, outer crossbeam 9 and the waist hole position of lower hem 15 set mounting hole, pass through spiral shell
Bolt and riveting nut are fastened together.Right baffle-plate 11, right shell body 10 are fixed on the inside of side plate column, and stretch into lower shrouding 2 and interior
In the fit-up gap of liner plate 6.
As shown in Figure 5, Figure 6, when internal arcing failure occurs, high temperature and high pressure gas and electric arc are produced in cabinet.Liner
Plate 6 plays cushioning effect, can absorb partial heat by deforming, and stop that electric arc prevents electric arc from directly burning lower shrouding." bow "
Type bending edges 16 are close to side plate column 17 under bolt effect, and are deformed upon with side plate column 17.Integral door plate is swollen to outside cabinet
Swollen, right baffle-plate 11 and right shell body 10 occur bending and deformation and block " bow " type bending edges 16 and side plate column 17 under pressure
Binding face so that electric arc and hot gas can not be directly sprayed outside cabinet from door-plate and side plate gap, so as to reach the mesh of barrier
's.
