Abstract
The utility model discloses a pressure relief device for switch cabinet, its key lies in: pressure relief device for switch cabinet 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. The utility model discloses simple structure, convenient to use, when the normal during operation of equipment, pressure release cover pressure release hole all around can help the inside ventilation cooling of cubical switchboard, reduces the inside probability that breaks down, in case the cubical switchboard breaks down when producing huge energy with pressure, the inside pressure jack -up pressure release cover that can make progress, the pressure release covers and to be opened by jack -up to ensure that the inside pressure energy of cubical switchboard obtains release very fast, thoroughly avoided the danger of cubical switchboard explosion, reduced economic loss.
Description
Technical field
The utility model relates to a kind of pressure relief device of switch cabinet.
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 pressure relief device of switch cabinet.
To achieve these goals, by the following technical solutions, a kind of pressure relief device of switch cabinet, it is characterized in that: described pressure relief device of switch cabinet 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.
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.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the close-up schematic view of A in Fig. 1;
Fig. 3 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 Figure 1 to Figure 3, a kind of pressure relief device of switch cabinet, described pressure relief device of switch cabinet 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.
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.
