Abstract
The utility model belongs to a pressure relief device of a marine AC metal enclosing switchgear cabinet. The device mainly comprises a cabinet body. The pressure relief device is disposed at the back side of the upper end surface of the cabinet body. The pressure relief device is an air relief cover that covers a pressure relief port that is communicated with an inner chamber of the cabinet body. The periphery of the pressure relief port is provided with a convex bending plate edge. The periphery of the air relief cover is provided with a downward folding cover edge. The cover edge of the air relief edge is disposed at the outer side of the bending plate edge. The upper end of the air relief cover is provided with a balancing weight. When an arc is generated inside the pressure relief device, high pressure generated by the arc can be effectively released, so that the pressure relief device is normally operated under the stable environment. The pressure relief device is advantaged by being simple in structure, good in usage effects, long in service lifetime and safe in usage.
Description
Technical field
The utility model belongs to a kind of ac metal closing switch gear cabinet pressure relief device peculiar to vessel.
Background technology
Sealing switch equipment cabinet is for straight, alternating-current installation/AC installation control field, uses extensively.In the fixing or motive objects such as factory, power plant, hotel, transformer station, subway control room, airplane equipment cabin, ship equipment cabin, be all widely used sealing switch equipment cabinet.Sealing switch equipment cabinet service requirement is stable, but the normal arc fault that occurs in sealing switch equipment switch cubicle, in the time of switch cubicle generation Internal faults arc, follow the appearance of electric arc, inside switch cabinet air pressure raises, and its internal pressure not only can be damaged electric equipment in cabinet, and the switch cabinet that also can break through sealing damages with switching devices cabinet and is close to causing damage of controller switching equipment field personnel, the electric equipment fault that makes its control, this equipment cabinet is scrapped.
Summary of the invention
The purpose of this utility model is to provide a kind of ac metal closing switch gear cabinet pressure relief device peculiar to vessel, can be in the time of the inner generation of sealing switch equipment cabinet electric arc, effectively the hyperbar of its generation is let out and removed, be beneficial to equipment cabinet normally operation under stable environment, have simple in structure, result of use is good, long service life and the safe advantage of use.For this reason, the utility model is mainly made up of cabinet, in the upper surface of cabinet, rear side is provided with pressure relief device, described pressure relief device is the gas releasing lid being buckled on the pressure relief opening communicating with cabinet intracorporeal space, the periphery of pressure relief opening is provided with the bent plate edge raising up, the periphery of gas releasing lid is provided with the cover rim of downward folding, and the cover rim of gas releasing lid is positioned at bent plate along outside, and the upper end of gas releasing lid is provided with balancing weight.Described pressure relief device is the gas releasing lid being buckled on the pressure relief opening communicating with cabinet intracorporeal space, the periphery of pressure relief opening is provided with the bent plate edge raising up, the periphery of gas releasing lid is provided with the cover rim of downward folding, the cover rim of gas releasing lid and be provided with extension spring at bent plate between the cabinet in outside.Described extension spring is positioned at four bights, lower surface of gas releasing lid.Said structure design has realized the purpose of this utility model.
The utility model can, sealing switch equipment cabinet is inner while there is electric arc, be let out the hyperbar of its generation to remove effectively, is beneficial to equipment cabinet normally operation under stable environment, has simple in structurely, and result of use is good, long service life and use safe advantage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of pressure relief device of the present utility model.
Fig. 3 is the structural representation of another pressure relief device of the present utility model.
Embodiment
As depicted in figs. 1 and 2, a kind of ac metal closing switch gear cabinet pressure relief device peculiar to vessel, is mainly made up of cabinet 2.In the upper surface of cabinet, rear side is provided with pressure relief device 1.Described pressure relief device is the gas releasing lid 4 being buckled on the pressure relief opening 6 communicating with cabinet intracorporeal space, the periphery of pressure relief opening is provided with the bent plate raising up along 5, the periphery of gas releasing lid is provided with the cover rim of downward folding, and the cover rim of gas releasing lid is positioned at bent plate along outside, and the upper end of gas releasing lid is provided with balancing weight 3.In the time of the inner generation of sealing switch equipment cabinet electric arc, the hyperbar gas being produced by arc fault is from the pressure relief opening gas releasing lid of upwards rushing to summit, gas releasing lid is upwards lifted, and the pressure relief opening of unlatching from pressure relief opening is discharged sealing switch equipment cabinet, can not cause damage hyperbar gas to equipment in cabinet.After pressure release, under the effect of balancing weight, gas releasing lid is descending, again seals pressure relief opening, is beneficial to equipment cabinet normally operation under stable environment.
As shown in Figure 3, the embodiment of another pressure relief device of the present utility model: described pressure relief device is the gas releasing lid being buckled on the pressure relief opening communicating with cabinet intracorporeal space, the periphery of pressure relief opening is provided with the bent plate edge raising up, the periphery of gas releasing lid is provided with the cover rim of downward folding, the cover rim of gas releasing lid and be provided with extension spring 7 along between the cabinet in outside at bent plate.Described extension spring is positioned at four bights, lower surface of gas releasing lid.In the time of the inner generation of sealing switch equipment cabinet electric arc, the hyperbar gas being produced by arc fault is from the pressure relief opening gas releasing lid of upwards rushing to summit, gas releasing lid is upwards lifted, extension spring is stretched, the pressure relief opening of opening from pressure relief opening is discharged sealing switch equipment cabinet, can not cause damage hyperbar gas to equipment in cabinet.After pressure release, under the effect of shrinking in extension spring, gas releasing lid is descending, again seals pressure relief opening, is beneficial to equipment cabinet normally operation under stable environment.
In a word, the utility model can, in the time of the inner generation of sealing switch equipment cabinet electric arc, be let out the hyperbar of its generation to remove effectively, be beneficial to equipment cabinet normally operation under stable environment, have simple in structurely, result of use is good, long service life and use safe advantage.
