Abstract
The utility model discloses a locomotive electrical cabinet explosion-proof hermatic door. The cabinet door is provided with more than one opening. A metal sheet which covers the opening is fixed on the cabinet door. The area of the opening is more than 1/3 of the area of the cabinet door. Before components inside the cabinet explode, the metal sheet, as a weak link, is destroyed firstly; and energy is discharged through the opening at the metal sheet safely and rapidly, thus mitigating damage of the explosion of the components inside the cabinet to the cabinet body, effectively avoiding shedding of the cabinet door and preventing expanding accidents. The locomotive electrical cabinet explosion-proof hermatic door provided by the utility model has advantages of simple structure, convenient maintenance and low cost.
Description
Technical field
The utility model relates to the explosive-proof sealed door of a kind of locomotive electric cad system cabinet.
Background technology
In the sealing cabinet that devices such as IGBT, fuse, capacitor are housed, devices such as IGBT, fuse, capacitor may produce blast when electric current is excessive, if energy can't be released safely and fast, can cause cabinet to damage, or even cabinet door consequence such as come off, the influence driving threatens to personal safety.
Existing sealed electrical cabinet blast resistance construction mainly contains two kinds:
1) at the outside slip-off preventing wirerope that increases of cabinet, the cabinet door is pinioned complex structure, not attractive in appearance; When blasting, must destroy the fastening structure on cabinet door and the cabinet earlier, the slip-off preventing wirerope just can work, and is bigger to cabinet and the infringement of other device.
On cabinet, open a hole, compress a rubber slab or stop up processing with glue; Perforate hour, explosion-proof effect is not obvious, if perforate is big, then take up room also big, technology is complicated, not attractive in appearance.
Summary of the invention
Technical problem to be solved in the utility model is, at the prior art deficiency, provides a kind of locomotive electric cad system cabinet explosive-proof sealed door, alleviates when device is blasted in the cabinet the infringement of cabinet, avoids the cabinet door to come off, and prevents the accident extension.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the explosive-proof sealed door of a kind of locomotive electric cad system cabinet, and described cabinet door is provided with one with upper shed, is fixed with a metallic plate that covers described opening on the described cabinet door; Described aperture area be the described cabinet shop front long-pending more than 1/3.
As preferred version, described cabinet door middle part is provided with four openings, and described metallic plate is fixed on the described cabinet door, and covers described four openings; Described metallic plate is fixed on the described cabinet door by rivet, seals by fluid sealant between described metal-sheet edges and the described cabinet door; The destruction tensile force of described metallic plate top rivet is more than 4 times of destruction tensile force of described metallic plate middle and lower part rivet.
Compared with prior art, the beneficial effect that the utility model had is: the utility model metallic plate is earlier destroyed as weak link when device is blasted in cabinet, energy security is released by the opening at metallic plate place apace, alleviated the infringement of the interior device blast of cabinet to cabinet, effectively avoid the cabinet door to come off, prevented the accident extension; The utility model is simple in structure, and is easy to maintenance, and cost is low; The utility model aperture area is big, and explosion-proof effect is better.
Description of drawings
Fig. 1 is the utility model one embodiment structural map;
Fig. 2 is the utility model one embodiment assembly drawing;
Fig. 3 is the state diagram at device blast back door in the utility model one embodiment cabinet.
Embodiment
As depicted in figs. 1 and 2, the utility model one embodiment is provided with four openings 3 on cabinet door 1, and metallic plate 2 is fixed on the cabinet door 1 by rivet A, B, and covers four openings 3, seals by fluid sealant between metallic plate 2 edges and the cabinet door 1.Its middle and upper part rivet A is bigger than bottom rivet B, and the destruction tensile force of rivet A is more than 4 times of destruction tensile force of rivet B.The area of four openings can reach the cabinet shop front long-pending more than 1/3.
Rivet A is fixed to metallic plate on the cabinet door, guarantees not come off at the explosion time metallic plate; Rivet B is fixed and clamped metallic plate on the cabinet door, and explosion time can come off or be destroyed.
When blasting, the pressure in the cabinet sharply rises, and metallic plate is stressed, when reaching the stressed limit of rivet B, rivet B is destroyed, and the stressed limit of rivet A is far above the stressed limit of rivet B, can be not destroyed, the metallic plate bottom becomes free end, upwards lifts under the effect of blast impulse power, the opening portion of cabinet door is all opened, as shown in Figure 3, energy is released by metallic plate place opening fast, has alleviated the infringement of blast to cabinet, avoid the cabinet door to come off, in order to avoid the accident extension.
Openings of sizes can be determined as the case may be.
