Abstract
The utility model discloses a kind of high-voltage switch gear cabinet state of emergency pressure relief device, comprise high-tension switch cabinet top cover and be arranged on the pressure port on described high-tension switch cabinet top cover.Be connected through the hinge between one side of described pressure port and high-tension switch cabinet top cover, under the drive of hinge, described pressure port can freely open and close at high-tension switch cabinet top cover, and other three limits of described pressure port are bonding by fixture glue with between high-tension switch cabinet top cover.Described pressure port is double-layer structure, and skin is iron wire Turbogrid plates, and internal layer is synthetic fiber layer.Be solid-state shape under described fixture glue normal temperature, when being heated, half curdled appearance can be fused into.Be connected through the hinge between one side of pressure port described in the utility model and high-tension switch cabinet top cover, under the drive of hinge, described pressure port can freely open and close at high-tension switch cabinet top cover, ensure that this device is in the state of emergency, pressure port can be raised rapidly during high-voltage switch gear cabinet inner high voltage gas rapid expansion, timely effusion, avoids meeting accident.
Description
Technical field
The utility model relates to high-tension electricity power distribution cabinet technical field, more particularly, relates to a kind of high-voltage switch gear cabinet state of emergency pressure relief device.
Background technology
The small high voltage switch cubicle of a current part is semi-hermetic type high-tension switch cabinet, is and arranges certain ventilation and heat position, but in order to ensure the interference not being subject to extraneous factor, described ventilating heat dissipating hole or the aperture of shutter all smaller.
When high-tension switch cabinet causes primary circuit short trouble to occur due to reasons such as short circuit, ageing of insulation or human operational errors in running, under the short circuit current of tens thousand of amperes, the high temperature and high pressure gas produced instantaneously effectively can not discharge in narrow cabinet within the extremely short time, switch cubicle just may be caused to burst, cause adjacent switch cabinet to damage, may personal safety be injured simultaneously.Therefore high-tension switch cabinet must possess effective pressure-relief measure.The pressure-relief measure that prior art middle-high voltage switch is taked, mainly by top pressure release, namely offers relief hole at top.Also the pressure relief plate adopting fiberglass or Ya Like material is had, but the former easily causes falling into dust in high voltage vacuum switchgear cabinet, the latter is rushed to open under the effect of high temperature and high pressure gas crunch, can fly in switchgear house civil strike, easily injure by a crashing object or smash miscellaneous equipment, even operator on duty be damaged.
So how to solve the problem be one's own profession those skilled in the art need consider problem.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, applicant, through repeatedly putting into practice improvement, devises a kind of high-voltage switch gear cabinet state of emergency pressure relief device, meets accident in high-voltage board cavity, and temperature raises, when pressure increases suddenly, emergency decompression.
Technical scheme: in order to realize foregoing invention object, the technical scheme that this practicality adopts is: a kind of high-voltage switch gear cabinet state of emergency pressure relief device, comprise high-tension switch cabinet top cover and be arranged on the pressure port on described high-tension switch cabinet top cover, described high-tension switch cabinet top cover is arranged bleeder port by pressure port covering position.Its Key Technologies Design is: described pressure port and be connected through the hinge between high-tension switch cabinet top cover, under the drive of hinge, described pressure port can freely open and close at high-tension switch cabinet top cover, and other three limits of described pressure port are bonding by fixture glue with between high-tension switch cabinet top cover.
The further technical scheme that this practicality adopts is: described pressure port is double-layer structure, and skin is iron wire Turbogrid plates, and internal layer is synthetic fiber layer.
The further technical scheme that this practicality adopts is: be connected and fixed by some mushroom rivets between described iron wire Turbogrid plates and synthetic fiber layer.
Other three limits of the above-mentioned pressure port mentioned are bonding by fixture glue with between high-tension switch cabinet top cover, and the further technical scheme that the utility model adopts is: be solid-state shape under described fixture glue normal temperature, can be fused into half curdled appearance when being heated.
Beneficial effect: compared with prior art, its beneficial effect is the utility model:
1, be connected through the hinge between one side of this practical described pressure port and high-tension switch cabinet top cover, under the drive of hinge, described pressure port can freely open and close at high-tension switch cabinet top cover, ensure that this device is in the state of emergency, pressure port can be raised rapidly during high-voltage switch gear cabinet inner high voltage gas rapid expansion, timely effusion, avoids meeting accident;
2, the pressure port that this practicality adopts is double-layer structure, skin is iron wire Turbogrid plates, internal layer is synthetic fiber layer, and iron wire Turbogrid plates can ensure to fall in high-tension switch cabinet in hard object or weight collision, and described synthetic fiber layer can ensure in cabinet not by invasion and attack such as dust foreign material.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of high-voltage switch gear cabinet of the utility model state of emergency pressure relief device.
Fig. 2 is the structural representation of pressure port in the utility model.
Embodiment
Below by a most preferred embodiment, the technical program is described in detail, but protection range of the present utility model is not limited to described embodiment.
As shown in Figure 1, a kind of high-voltage switch gear cabinet state of emergency pressure relief device, comprises high-tension switch cabinet top cover 1 and is arranged on the pressure port 2 on described high-tension switch cabinet top cover 1, described high-tension switch cabinet top cover 1 is arranged bleeder port by pressure port 2 covering position.One side of described pressure port 2 is connected by hinge 3 with between high-tension switch cabinet top cover 1, and other three limits of described pressure port 2 are bonding by fixture glue with between high-tension switch cabinet top cover 1.
As shown in Figure 2, described pressure port 2 is double-layer structure, and skin is iron wire Turbogrid plates 21, and internal layer is synthetic fiber layer 22.Be connected and fixed by some mushroom rivets between described iron wire Turbogrid plates 21 and synthetic fiber layer 22.
Be solid-state shape under described fixture glue normal temperature, when being heated, half curdled appearance can be fused into.Actual when meeting accident, in high-tension switch cabinet, gas is heated rapid expansion, because the rising rapidly of temperature, described fixture glue is molten into half curdled appearance, then three limits of pressure port 2 connect loosening, under the influence of air pressure, described pressure port 2 is outwards opened, and releases gases at high pressure rapidly.
The above is only preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection range of the present utility model.
