Abstract
The utility model discloses an indoor inflation ring network cabinet explosion-proof device. The indoor inflation ring network cabinet explosion-proof device comprises an explosion-proof sheet (1) and a pressure plate (2), and a buffer plate (4) is installed under the explosion-proof sheet (1) through double-screw bolts (3). When the explosion-proof device works, fragments and high pressure gas which generate after the explosion-proof sheet (1) is broken impact the buffer plate (4) first and diffuse around; when the buffer plate (4) is damaged by impact, the impact force of the fragments and the high pressure gas which generate after the explosion-proof sheet (1) is broken is substantially reduced, so that a base plate (5) of an inflation ring network cabinet is protected against severe deformation, and components installed on the base plate (5) are effectively protected.
Description
Technical field
The utility model relates to a kind of indoor switch equipment, special relevant with indoor Inflatable ring main unit.
Background technology
Existing indoor Inflatable ring main unit explosion-protection equipment is by pressing plate, burst disk to be installed in Pneumatic box body bottom, when pressure is increased to certain value, burst disk can automatic explosion, thereby guaranteeing that all the other sides of Pneumatic box body there will not be injures operating personnel or other article because of explosion.In the course of the work, burst disk and high pressure gas are known from experience directly impact Inflatable ring main unit base plate to such explosion-protection equipment, cause base plate explosion or major injury, and the components and parts that are arranged on base plate are caused damage.
Utility model content
The utility model is mainly to provide a kind of the indoor of components and parts that can protect base plate and be arranged on base plate and fills
Gas ring main unit explosion-protection equipment.
The technical solution of the utility model is: a kind of indoor Inflatable ring main unit explosion-protection equipment, comprise burst disk, pressing plate, and be characterised in that, below burst disk, by double-screw bolt, buffer board is installed.
The indoor Inflatable ring main unit explosion-protection equipment that the utility model provides; when explosion-protection equipment is worked; burst disk is broken; fragment after burst disk fragmentation and high pressure gas are known from experience first damping of shocks plate; simultaneously to surrounding diffusion, when buffer board is during by impact failure, the fragment after burst disk fragmentation and the impulsive force of gases at high pressure reduce greatly; so just can prevent Inflatable ring main unit base plate gross distortion, thereby effectively protection is arranged on the components and parts on base plate.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing indoor Inflatable ring main unit explosion-protection equipment;
Fig. 2 is the structural representation of explosion-protection equipment embodiment for the indoor Inflatable ring main unit of the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, burst disk 2, pressing plate 3, double-screw bolt 4, buffer board 5, base plate
As shown in Figure 2, the indoor Inflatable ring main unit explosion-protection equipment of the utility model, comprises burst disk 1, pressing plate 2, it is characterized in that, below burst disk 1, by double-screw bolt 3, buffer board 4 is installed.
When explosion-protection equipment is worked; burst disk 1 is broken; fragment after burst disk 1 fragmentation and high pressure gas are known from experience first damping of shocks plate 4; to surrounding, spread simultaneously; when buffer board 4 is during by impact failure; fragment after burst disk 1 fragmentation and the impulsive force of gases at high pressure reduce greatly, so just can prevent Inflatable ring main unit base plate 5 gross distortions, thereby effectively protection is arranged on the components and parts on base plate 5.
Claims (1)
1. an indoor Inflatable ring main unit explosion-protection equipment, comprises burst disk (1), pressing plate (2), it is characterized in that: in burst disk (1) below, by double-screw bolt (3), buffer board (4) is installed.
