Abstract
The invention discloses a pressure relief apparatus of a high voltage switch cabinet. The apparatus includes a cabinet body; a pressure relief cover is arranged above a busbar chamber of the cabinet body; the pressure relief cover and the busbar cover are connected by metal screws; and pressure relief holes are arranged on the pressure relief cover. According to the pressure relief apparatus provided by the invention, it can be ensured that high voltage switch cabinet equipment can carry out operation safely; and safety of working personnel can also be ensured; meanwhile, heat radiation of the high voltage switch cabinet can be carried out conveniently.
Description
Technical field
The present invention relates to appliance switch field, be specifically related to a kind of pressure relief apparatus of high voltage switch cabinet.
Background technology
In current electric power system, middle (KYN28-12) exchanges closes high voltage switchgear, and as shown in Figure 2, Figure 3 and Figure 4, comprise cabinet, above the bus-bar room of cabinet, arrange decompression cover, decompression cover is connected by plastic screw with bus-bar room; For there is any short trouble at bus-bar room in its object, when causing bus-bar room internal pressure sharply to increase, decompression cover can be rushed to open, and then reaches the object of cabinet internal pressure relief, ensures the security of operation of high-tension switch cabinet.Though this kind of pressure relief device can make bus-bar room internal pressure reduce when fault, support equipment safety, if now have personnel in switchgear house, easily enough potential safety hazard is become to operating personnel; Comprehensive it, this kind of high-tension switch cabinet has following defect:
One is, causes pressure increase in bus-bar room fault, and when decompression cover is rushed out, decompression cover can fly in switchgear house civil strike, easily injures by a crashing object or smashes miscellaneous equipment, as now having operator on duty at switchgear house, easily forms potential safety hazard to operating personnel;
Two are, decompression cover is completely closed by bus-bar room entirety, are unfavorable for the heat radiation of switch cubicle, unfavorable to the safe operation of switch cubicle.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, provide one can ensure high-voltage switch gear cabinet equipment security of operation, can worker safety be ensured again, be conducive to again the pressure relief apparatus of high voltage switch cabinet of switch cubicle heat radiation simultaneously.
To achieve these goals, the technical solution used in the present invention is:
Described pressure relief apparatus of high voltage switch cabinet, comprises cabinet, above the bus-bar room of cabinet, be provided with decompression cover, and described decompression cover is connected by metallic screw with described bus-bar room, and described decompression cover is provided with relief hole.
On described decompression cover, the below of relief hole is provided with woven wire.
Described relief hole is located in the middle part of described decompression cover.
Described relief hole is more than one group.
Described relief hole is uniformly distributed on described decompression cover.
Described relief hole is rectangular opening.
Described woven wire is welded on described decompression cover.
The technical scheme that described pressure relief apparatus of high voltage switch cabinet adopts, compared with prior art, has the following advantages:
First, when bus-bar room breaks down, cabinet inner high voltage gas releases cabinet by relief hole, ensure that cabinet safety;
Secondly, adopt metal screws to fix decompression cover and bus-bar room, when avoiding cabinet bus-bar room internal fault, decompression cover is gone out cabinet top, in the situation that switchgear house civil strike flies, eliminate the potential safety hazard to miscellaneous equipment and personnel, ensure that the safety of staff;
Again, when cabinet normally runs, the heat produced in bus-bar room, can be shed cabinet by this relief hole timely, is convenient to the reduction of cabinet operationally bus temperature, improves the practical fail safe of high-tension switch cabinet;
Finally, by arranging wire mesh below relief hole, on cabinet degree of protection without any impact, ensure that the safety in utilization of high-tension switch cabinet; Structure of the present invention is simple, easy to use.

Embodiment
Contrast accompanying drawing below, by the description to optimum embodiment, the specific embodiment of the present invention is described in further detail.
As shown in Figures 1 and 2, described pressure relief apparatus of high voltage switch cabinet, comprises cabinet 1, and above the bus-bar room 2 of cabinet 1, be provided with decompression cover 3, decompression cover 3 is connected by metallic screw 5 with bus-bar room 2, and decompression cover 3 is provided with relief hole 6.
Be provided with woven wire 7 below the position that decompression cover 3 is provided with relief hole 6, woven wire 7 is welded on decompression cover 6; Woven wire 7 can strengthen the intensity of the decompression cover 3 being provided with relief hole 6 place, and when preventing bus-bar room 2 internal pressure excessive, the position that decompression cover 3 is positioned at relief hole 6 is broken through, and further ensures the safety of pressure relief apparatus of high voltage switch cabinet; The thickness of woven wire 7 and the visual concrete condition adjustment of size.
Relief hole 6 is located in the middle part of decompression cover 3, can ensure that pressure pcl gathers at middle part and distributes in time like this; The visual concrete condition adjustment of number of relief hole 6, relief hole 6 is more than one group, often organizes the visual concrete condition adjustment of number of relief hole 6; Relief hole 6 is uniformly distributed on decompression cover 3; Such relief hole 6 being evenly distributed on decompression cover 3, the Quick uniform being more conducive to pressure sheds; The visual concrete condition adjustment of the shape of relief hole 6, can be rectangle, circle and oval etc.; For convenient processing and manufacture, described relief hole 6 is rectangular opening.
Described pressure relief apparatus of high voltage switch cabinet, metallic screw 5 is adopted to connect decompression cover 3 and bus-bar room 2, the stable connection of decompression cover 3 and bus-bar room 2, when pressure is excessive, decompression cover 2 can not go out cabinet top, and then avoid the situation that occurs that decompression cover 3 flies in switchgear house civil strike, avoid the potential safety hazard to miscellaneous equipment and personnel; By arranging relief hole 6 on decompression cover 3, when bus-bar room 2 internal pressure sharply rises, pressure slowly gushes by relief hole 6, simultaneously, the heat produced in bus-bar room 2 sheds cabinet 1 by relief hole 6 timely, is convenient to the reduction of cabinet 1 operationally bus temperature; Further provide the safety in utilization of high-tension switch cabinet.
Above to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
