The Main Function of switch cubicle (switchgear) carries out generating electricity in electric power system, transmits electricity, in the process of distribution and electric energy conversion, carries out folding, control and protection power consumption equipment.Parts in switch cubicle mainly contain the compositions such as circuit breaker, isolating switch, on-load switch, operating mechanism, instrument transformer and various protective devices.Mainly be applicable to various different occasion such as power plant, transformer station, petrochemical industry, metallurgical steel rolling, industry light industry textile industry, industrial enterprise and residential quarters, skyscraper etc.
At present; along with the increase of the load of switch cubicle; the situation that switch cubicle usually can be short-circuited in use procedure; and when inside switch cabinet is short-circuited fault; larger impact air-flow can be produced therein; impact air-flow will cause the damage of equipment, and has seriously jeopardized personal safety, and then a kind of pressure release top board of specialized designs is very important.
But for the deficiencies in the prior art, developer is necessary that development one is reasonable in design, structure simple, when inside switch cabinet is short-circuited fault, effectively can be released in the larger impact air-flow produced in switch cubicle, guarantee effectively to realize safety relief, the switch cubicle pressure release top board to the damage that equipment causes can also be avoided simultaneously.
Utility model content
For solving prior art Problems existing, the utility model object provide a kind of reasonable in design, structure simple, when inside switch cabinet is short-circuited fault, effectively can be released in the larger impact air-flow produced in switch cubicle, guarantee effectively to realize safety relief, the switch cubicle pressure release top board to the damage that equipment causes can also be avoided simultaneously.
For solving above technical problem, the utility model realizes by the following technical solutions:
A kind of switch cubicle pressure release top board, comprise switch cubicle top board and pressure release cover plate, described switch cubicle mounting of roof plate, on switch cubicle, described switch cubicle top board offers pressure relief opening, and described pressure release cover plate is arranged on switch cubicle top board and lid is located on pressure relief opening;
Described pressure release cover plate side is locked on switch cubicle top board by securing member, described pressure release cover plate opposite side is arranged on switch cubicle top board by plastic fastener, evenly offers the slotted eye of multiple linearly shape arrangement on described pressure release cover plate and near the side of securing member.
In a preferred embodiment of the present utility model, evenly offer multiple bolt hole in the side of described pressure release cover plate, evenly offer multiple mounting groove at the opposite side of described pressure release cover plate.
In a preferred embodiment of the present utility model, described securing member comprises clamping screw and packing ring.
In a preferred embodiment of the present utility model, described plastic fastener is plastic bolt.
In a preferred embodiment of the present utility model, described switch cubicle top board is fixed by bolt and is arranged on switch cubicle.
Compared with prior art, the utility model is provided with switch cubicle top board on switch cubicle, switch cubicle top board offers pressure relief opening, and on pressure relief opening, be also covered with pressure release cover plate, and the side of pressure release cover plate is fixed on switch cubicle top board by clamping screw, opposite side is fixed on switch cubicle top board by plastic bolt, when switch cubicle internal cause short trouble produces impact air-flow, pressure release cover plate is subject to larger impulsive force, due to the poor-performing of plastic bolt anti-impact force, and then plastic bolt is flown out, after plastic bolt flies out, pressure release cover plate is under a larger impact force along the slotted eye bending of linearly shape arrangement, pressure release cover plate is effectively opened, the impact air-flow that smooth release-push cabinet inside produces, guarantee effectively to realize safety relief.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the A place enlarged drawing of Fig. 1.
Embodiment
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
Shown in seeing figures.1.and.2, a kind of switch cubicle pressure release top board provided in figure, comprises switch cubicle top board 100 and pressure release cover plate 200.
Be provided with at switch cubicle top board 100 and offer installing hole, by the bolt through installing hole, switch cubicle top board 100 is fixedly mounted on the top of switch cubicle 400, switch cubicle top board 100 offers pressure relief opening 110, and pressure release cover plate 200 is arranged on switch cubicle top board 100 and lid is located on pressure relief opening 110.
Multiple bolt hole 220 is evenly offered in the left side of pressure release cover plate 200, multiple mounting groove 230 is evenly offered on the right side of pressure release cover plate 200, by the clamping screw 510 through bolt hole 220, the left side of pressure release cover plate 200 is fixed on switch cubicle top board 100 firmly, and be also provided with packing ring 520 between clamping screw 510 and bolt hole 220, the setting of packing ring 520 can improve the stability on the left of pressure release cover plate and between switch cubicle top board further.
By the plastic bolt 300 through mounting groove 230, the right side of pressure release cover plate 200 is arranged on switch cubicle top board 100, on pressure release cover plate 200 and near bolt hole 220 side, evenly offers the slotted eye 210 that multiple linearly shape arranges.
