Abstract
The utility model discloses a pressure relieving device of a closed high-voltage switch cabinet. The pressure relieving device comprises a cabinet body and a pressure relieving cover plate, wherein the cabinet body is internally provided with a handcart room, an instrument room, a busbar room and a cable room; high-pressure gas release channels of the handcart room, the instrument room, the busbar room and the cable room are converged under the pressure relieving cover plate arranged at the upper part of the cabinet body; one side of the pressure relieving cover plate is movably connected with the cabinet body; the other side of the pressure relieving cover plate is fixed by a nylon screw. When the closed high-voltage switch cabinet is in the normal working state, the pressure relieving cover plate and the cabinet keep the closed state; when the malfunction occurs in the cabinet, the generated high-temperature and high-pressure gas impacts the pressure relieving cover plate, the nylon screw is stressed to unplug, the pressure relieving cover plate is completely opened like a door, and the high-temperature and high-pressure gas can be released instantaneously, thereby preventing the major safety accident.
Description
Technical field
The utility model relates to a kind of closed high-tension switch cabinet, relates in particular to a kind of pressure relief device of high-tension switch cabinet.
Background technology
The problem that high-temperature gas pressure discharged when closed high-tension switch cabinet was structurally all considered fault mostly.The top of handcart chamber, bus-bar room and cable vault in traditional closed high-tension switch cabinet is equipped with pressure relief device, this pressure relief device gases at high pressure release channel general and in the cabinet is connected, its structure is a rectangle metal louvres plate, one side is fixed with iron screw, and opposite side is fixed with nylon screw.In actual motion, fixedly shutter board can only satisfy each chamber ventilated thermolysis, but is difficult to satisfy the release of fault pressure.When breaking down in the cabinet, the shutter board distortion is opened, release pressure and drainage gas, and top board is scrapped after the pressure release.When fault was serious, because the switch cubicle safe pressure relief device is not smooth, high temperature gas flow discharged by high-voltage board is positive, causes the serious accident of operating personnel's serious burn.
Summary of the invention
The purpose of this utility model is the pressure relief device that overcomes in the existing closed high-tension switch cabinet, the needs of gases at high pressure pressure release in the time of can not satisfying fault, a kind of improved closed high-tension switch cabinet pressure relief device is provided, can solves when breaking down in the cabinet release problem of gases at high pressure preferably.
The purpose of this utility model is achieved through the following technical solutions, this closed high-tension switch cabinet pressure relief device comprises cabinet, pressure release cover plate, be provided with handcart chamber, control room, bus-bar room, cable vault in the described cabinet, high pressure gas body release channels such as described handcart chamber, control room, bus-bar room, cable vault all are pooled to the pressure release cover plate below on cabinet top, one side of described pressure release cover plate and cabinet are for flexibly connecting, and the opposite side of described pressure release cover plate is fixed with nylon screw.
Described pressure release cover plate is that rotating shaft is connected or hinge connects with the flexible connection of cabinet.
When closed high-tension switch cabinet is in normal operating conditions, pressure release cover plate and cabinet keep closed state, when breaking down in the cabinet, the high temperature and high pressure gas that produces is pooled to the top of switch cubicle, impact the pressure release cover plate, nylon screw is stressed to be unpluged, and the pressure release cover plate is opened fully as door, resemble the high temperature and high pressure gas instantaneous relase and fall, prevent serious accident.
The beneficial effects of the utility model:
1, the pressure release cover plate is flexibly connected by fixedly connected making into, has promptly reached the effect of sealing cabinet at ordinary times, can reach when breaking down in the cabinet purpose of the high temperature and high pressure gas instantaneous relase of generation again
2, pressure release passage is big, and pressure release speed is fast, and is safe and effective.
3, the structure and the profile that have kept former cabinet.
Description of drawings
Describe embodiment of the present utility model in detail below in conjunction with accompanying drawing
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a vertical view of the present utility model
Among the figure: 1, cabinet 2, pressure release cover plate 3, rotating shaft 4, nylon screw
Embodiment
As shown in Figure 1 and Figure 2, this closed high-tension switch cabinet pressure relief device comprises cabinet 1, pressure release cover plate 2, be provided with handcart chamber, control room, bus-bar room, cable vault in the cabinet 1, high pressure gas body release channels such as handcart chamber, control room, bus-bar room, cable vault all are pooled to pressure release cover plate 2 belows on cabinet top, one side of pressure release cover plate 2 is connected by rotating shaft 3 with cabinet, and the opposite side of pressure release cover plate 2 is fixing with nylon screw 4.When closed high-tension switch cabinet is in normal operating conditions, pressure release cover plate 2 keeps closed state with cabinet 1, when breaking down in the cabinet, the high temperature and high pressure gas that produces is pooled to the top of switch cubicle, impact pressure release cover plate 2, nylon screw 4 stressed unpluging, pressure release cover plate 2 is opened fully as door, resemble the high temperature and high pressure gas instantaneous relase and fall, prevent serious accident.
Claims (3)
