Abstract
The invention discloses a pressure release structure of an electric switch cabinet. The keys of the pressure release structure are in that the pressure release structure of the electric switch cabinet comprises a pressure release cover disposed at the top of the switch cabinet, four corners of the pressure release cover are connected with edges at the top of the switch cabinet through bolts, compression springs respectively sleeve the lower ends of the bolts, nuts are finally fixed to the lower ends of the bolts, and then the nuts and the top of the switch cabinet are spaced for a certain distance; and the periphery of the pressure release cover is further provided with pressure release holes. The periphery of the pressure release cover is further provided with the pressure release holes, and a slow descending device is disposed between the bottom face of an edge of the pressure release cover and the top face of the corresponding edge at the top of the switch cabinet. The pressure release structure is simple in structure and convenient to use, and can ensure a pressure in the switch cabinet to be rapidly released; and the pressure release structure completely prevents the danger of explosion of the switch cabinet, and reduces economic loss.
Description
Technical field
The present invention relates to a kind of cabinet pressure relief.
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.
Summary of the invention
The object of this invention is to provide a kind of cabinet pressure relief.
To achieve these goals, by the following technical solutions, a kind of cabinet pressure relief, it is characterized in that: described cabinet pressure relief 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, slow descending device is provided with between the bottom surface of pressure release shroud rim and switch cubicle top end face, wherein slow descending device is by stationary magazine creel be positioned at the movable post that stationary magazine creel slides and form, the inwall of stationary magazine creel is provided with the sloping platform in inclination, and the surface of movable post is provided with the reed of level.
The length of described Compress Spring is more than 10CM.
Structure of the present invention 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.

Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described further.
As shown in Figures 1 to 5, a kind of cabinet pressure relief, described cabinet pressure relief 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, slow descending device is provided with between the bottom surface of pressure release shroud rim and switch cubicle top end face, wherein slow descending device is by stationary magazine creel 7-2 be positioned at the movable post 7-1 that stationary magazine creel slides and form, the inwall of stationary magazine creel is provided with the sloping platform 7-3 in inclination, and the surface of movable post is provided with the reed of level.
The length of described Compress Spring 5 is more than 10CM.
Structure of the present invention 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 inwall of stationary magazine creel is provided with the sloping platform in inclination, and the surface of movable post is provided with the reed of level.Such design, can make pressure release cover on the process of decline slowly, extend the time that pressure release cover declines, avoid the short time repeatedly to explode to the impact of pressure release cover.
Claims (2)
1. a cabinet pressure relief, it is characterized in that: described cabinet pressure relief 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, slow descending device is provided with between the bottom surface of pressure release shroud rim and switch cubicle top end face, wherein slow descending device is by stationary magazine creel be positioned at the movable post that stationary magazine creel slides and form, the inwall of stationary magazine creel is provided with the sloping platform in inclination, and the surface of movable post is provided with the reed of level.
2. cabinet pressure relief as claimed in claim 1, is characterized in that: the length of described Compress Spring is more than 10CM.
