Summary of the invention
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, provide a kind of when operate as normal ventilation and heat and good dustproof effect, the pressure relief device that a kind of switchgear that can the short time pressure release during fault is used.
The technical scheme that solves the problems of the technologies described above is:
The pressure relief device that a kind of switchgear is used, the pressure relief device that described switchgear is used comprises: top cover, web plate, dust excluding plate; The top cover lower end is fixed on the through hole of top board in the switchgear, and there is the through hole corresponding with the through hole of top board the top cover upper surface; Web plate covers on the through hole of top cover upper surface; In top cover, be provided with dust excluding plate below the web plate, leave the gap between dust excluding plate and the top cover inwall.
Described web plate is connected with securing member with dust excluding plate.
The securing member that described web plate one side that is positioned at the switchgear front is made with metal material is connected with top cover, being positioned at the securing member that web plate one side of switchgear back makes with nonmetallic materials is connected with top cover, web plate has ventilating heat dissipating hole, its shape be can breathe freely every coral.
The beneficial effects of the utility model are: can prevent dust during the utility model operate as normal, again can ventilation and heat, can also utilize the hot gas that expands in the switchgear to wash the securing member of the little nonmetallic materials of fastening strength open during fault, one side of web plate and dust excluding plate is lifted to top, switchgear back together, rapidly hot gas in the switchgear is discharged to the top, back of equipment, the safety of other components and parts and Field Force in the equipment has been guaranteed in the designing requirement of pressure release when both having satisfied fault again.The utility model provides strong guarantee to the person, device security and power supply reliability, has satisfied the demand for security of switchgear, has solved the defective that the pressure release of prior art switchgear exists.The utility model is applicable to various switchgears, and cost is low, makes easily.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further specified.
Fig. 1 is the utility model switchgear front view; Fig. 2 is a pressure relief device partial enlarged drawing among Fig. 1; Fig. 3 is the vertical view of Fig. 2; Fig. 4 is the M-M cutaway view of Fig. 2.
The structure that the utility model structure is same as the prior art adopts identical sequence number to represent.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the utility model provides a kind of distribution switchgear A, and this distribution switchgear A mainly comprises shell 10; In this shell 10, be provided with: bus-bar room E, circuit breaker cart chamber B, the C of cable vault, the D of relay control room, at bus-bar room E, the top of circuit breaker cart chamber B is provided with pressure relief device 30.
