Abstract
The utility model discloses an electrical switching cabinet pressure release system, its key lies in: electrical switching cabinet pressure release system is including setting up in the pressure release cover at cubical switchboard top, and bolt and cubical switchboard top edge connection are passed through to four angles of this pressure release cover, and the pot head is equipped with compression spring and final and fixes with the nut under this bolt to it separates certain distance to make between nut and the cubical switchboard top, the pressure release cover still is provided with the pressure release hole all around. Be provided with the air bag between the marginal top surface in the bottom surface and cubical switchboard top of pressure release flaring reason, the bottom of air bag is provided with inlet port and venthole, and wherein the inlet port is bigger than the venthole, and the inboard of inlet port is provided with and keeps off the page or leaf. The utility model discloses simple structure, convenient to use can ensure that the inside pressure energy of cubical switchboard obtains release very fast, has thoroughly avoided the danger of cubical switchboard explosion, has reduced economic loss.
Description
Technical field
The utility model relates to a kind of cabinet pressure relief system.
Background technology
Switch cubicle is a kind of large electric appliances equipment, and its inside has a large amount of electronic components, operationally can produce a large amount of heats; During normal work, these heats can be come out by the louvre on switch cabinet body.But, once inside switch cabinet element failure, will produce a large amount of heats and pressure, the louvre on switch cabinet body cannot discharge the energy of cabinet inside very soon, the danger just likely causing switch cubicle to explode, brings huge potential safety hazard and economic loss.
Utility model content
The purpose of this utility model is to provide a kind of cabinet pressure relief system.
To achieve these goals, by the following technical solutions, a kind of cabinet pressure relief system, it is characterized in that: described cabinet pressure relief system comprises the pressure release cover being arranged at switch cubicle top, four angles of this pressure release cover are connected with switch cubicle top by bolt, this bolt lower end is arranged with Compress Spring and final and nut is fixed, thus makes spaced apart certain distance at nut and switch cubicle top; Described pressure release cover surrounding is also provided with relief hole, air bag is provided with between the bottom surface of pressure release shroud rim and switch cubicle top end face, the bottom of air bag is provided with air admission hole and venthole, and wherein air admission hole is larger than venthole, and the inner side of air admission hole is provided with block page.
The length of described Compress Spring is more than 10CM.
The utility model structure is simple, easy to use, by arranging at switch cubicle top the problem that pressure release cover solves inside switch cabinet pressure release; When equipment normally works, the relief hole of pressure release cover surrounding can help inside switch cabinet ventilation and heat, reduces the inner probability broken down; Break down once switch cubicle and produce huge energy and pressure, inner pressure can upwards jack-up pressure release cover, due to the connecting bolt of pressure release cover and switch cubicle being provided with Compress Spring, therefore, pressure release cover can be opened by jack-up, thus guarantee that the pressure energy of inside switch cabinet is discharged very soon, thoroughly avoid the danger of switch cubicle blast, decrease economic loss.

Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of airbag;
Fig. 3 is the close-up schematic view of A in Fig. 1;
Fig. 4 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figures 1 to 4, a kind of cabinet pressure relief system, described cabinet pressure relief system comprises the pressure release cover 2 being arranged at switch cubicle 1 top, four angles of this pressure release cover 2 are connected with switch cubicle 1 top by bolt 4, this bolt 4 lower end is arranged with Compress Spring 5 and final fixes with nut 6, thus makes spaced apart certain distance at nut 6 and switch cubicle 1 top; Described pressure release cover 2 surrounding is also provided with relief hole 3, air bag 7 is provided with between the bottom surface of pressure release shroud rim and switch cubicle top end face, the bottom of air bag is provided with air admission hole 7-2 and venthole 7-3, and wherein air admission hole is larger than venthole, and the inner side of air admission hole is provided with block page 7-1.
The length of described Compress Spring 5 is more than 10CM.
The utility model structure is simple, easy to use, by arranging at switch cubicle top the problem that pressure release cover solves inside switch cabinet pressure release; When equipment normally works, the relief hole of pressure release cover surrounding can help inside switch cabinet ventilation and heat, reduces the inner probability broken down; Break down once switch cubicle and produce huge energy and pressure, inner pressure can upwards jack-up pressure release cover, due to the connecting bolt of pressure release cover and switch cubicle being provided with Compress Spring, therefore, pressure release cover can be opened by jack-up, thus guarantee that the pressure energy of inside switch cabinet is discharged very soon, thoroughly avoid the danger of switch cubicle blast, decrease economic loss.The bottom of air bag is provided with air admission hole and venthole, air bag can the air inlet when pressure release cover moves upward, now air admission hole and venthole all can air inlets, and when pressure release cover moves downward, block page blocks air admission hole, venthole is only had to give vent to anger, airbag is exitted slowly, and the also decline slowly of pressure release cover, so just extends the fall time of pressure release cover,, there is blast continuously in the short time that can effectively prevent thus repeatedly pressure release cover impacted in abundant pressure release.
Claims (2)
1. a cabinet pressure relief system, it is characterized in that: described cabinet pressure relief system comprises the pressure release cover being arranged at switch cubicle top, four angles of this pressure release cover are connected with switch cubicle top by bolt, this bolt lower end is arranged with Compress Spring and final and nut is fixed, thus makes spaced apart certain distance at nut and switch cubicle top; Described pressure release cover surrounding is also provided with relief hole, air bag is provided with between the bottom surface of pressure release shroud rim and switch cubicle top end face, the bottom of air bag is provided with air admission hole and venthole, and wherein air admission hole is larger than venthole, and the inner side of air admission hole is provided with block page.
2. cabinet pressure relief system as claimed in claim 1, is characterized in that: the length of described Compress Spring is more than 10CM.
