Abstract
A pressure release device for a high-voltage switchgear solves the possible problems that the pressure release device is damaged, and even personal safety is threatened in the prior art. The pressure release device for the high-voltage switchgear is characterized by comprising nylon screws, a decompression cover plate, door hinges, a top plate and a pressure release passage which are all mounted on the external side of the top plate of the pressure release passage. One side of the decompression cover is fixed by the door hinges, the other side of the door hinges is fixed on the top plate of a cabinet of the pressure release passage, and then a hinge type movable end is formed. The other side of the decompression cover plate is fixed on the top plate of the cabinet of the pressure release passage by the nylon screws, and then a pressure release end is formed. Resistance produced when inner pressure is released by the pressure release device can enable the inner pressure to be released reliably and safely.
Description
Technical field
The utility model relates to a kind of high-tension apparatus pressure relief device.
Background technology
Metal enclosed switchgear (hereinafter to be referred as switchgear) causes in internal fault under the condition of electric arc that the arc energy of generation will cause internal pressure to raise, and makes equipment produce mechanical stress; Perhaps make some inner material breakdown go out gas or steam; Pressure and gas in the release-push equipment safely all are provided with pressure relief device and passage, existing pressure relief device; Generally discharging end by stiff end and pressure forms; When needs pressure discharged, the pressure of opening pressure relief device discharged end, to reach the purpose that pressure discharges.
Existing pressure relief device generally discharges end by stiff end and pressure and forms, when pressure discharges; Stiff end is motionless, when internal pressure discharges, opens pressure and discharges end, and stiff end will be given reaction force of internal pressure; Discharge to hinder internal pressure, do not reach the optimum efficiency that pressure discharges, perhaps the build-up of pressure releasing device damages; So that cause the possibility of personal safety injury, the stiff end of pressure relief device will be given reaction force of internal pressure, this is its shortcoming.
Summary of the invention
The purpose of the utility model is: a kind of high-tension apparatus pressure relief device is provided, exists the build-up of pressure releasing device to damage to solve prior art, so that cause the possible problem of personal safety injury.
Reaching the technical scheme that the purpose of the utility model takes is: a kind of high voltage switchgear pressure relief device; It is characterized in that: include nylon screw, pressure release cover plate, hinge, top board, pressure relief channels; Said mechanism all is installed on the outside of pressure relief channels place top board; One side of pressure release cover plate is fixed by hinge, and the opposite side of hinge is fixed on the cabinet top board of pressure relief channels, forms articulated movable end; The opposite side of pressure release cover plate is fixed on by nylon screw on the cabinet top board of pressure relief channels, and decomposition pressure discharges end.
The beneficial effect that the utility model reaches is: adopt the utility model; When internal pressure discharges; Open pressure and discharge end; Pressure relief device just is similar to open the door and equally is opened, and solves the resistance that pressure relief device gives when internal pressure discharges, can make internal pressure reliably, safe release.
Description of drawings
Fig. 1: the structural representation of the utility model.
Embodiment
The architectural feature of the utility model more at large is described below in conjunction with accompanying drawing.
A kind of high voltage switchgear pressure relief device; Include nylon screw 1, pressure release cover plate 2, hinge 3, top board 4, pressure relief channels 5; One side of pressure release cover plate 2 is fixing by hinge 3; The opposite side of hinge 3 is fixed on the cabinet top board 4 of pressure relief channels 5, forms articulated movable end; The opposite side of pressure release cover plate 2 is fixed on by nylon screw 1 on the cabinet top board 4 of pressure relief channels 5, and decomposition pressure discharges end.Can open nylon screw 1 through internal pressure, play explosion-proof, pressure release cover plate 2 can rotate around hinge 3.
During pressure relief device work: when internal pressure discharges, open the nylon screw (explosion-proof screw) 1 that pressure discharges end, the thrust that pressure release cover plate 2 is borrowing pressure to discharge is rotation axis with hinge 3, and pressure release cover plate 2 just is similar to open the door and equally opens outwardly.Solve the resistance that pressure relief device gives when internal pressure discharges, can make internal pressure reliably, safe release.At normal condition downforce releasing device, switching devices plays protective action.
