Abstract

The utility model discloses an electrical switch cabinet pressure releasing device and an electrical switch cabinet. The key points are that: the pressure releasing device includes a pressure releasing cover which is arranged on a cabinet body pressure releasing mouth; one end of the pressure releasing cover is fixed on the cabinet body, and the other end is in the lap joint with the cabinet body; one side of the cabinet body which is connected with a fixing end of the pressure releasing cover is provided with a baffle plate which restrains the rotation of the pressure releasing cover; the pressure releasing cover is connected with the cabinet body via a bolt or a hinge; and the pressure releasing device is arranged on the top of the electrical cabinet. The electrical switch cabinet pressure releasing device puts an end to the original defects and disadvantages. In the prior art, the gas generated in a short circuit fault is released via small holes and shutters, and the electrical switch cabinet pressure releasing device adopts the instant releasing cover opening mode, so the flow releasing capability is greatly improved, and the product protection grade is also greatly improved, and consequently the maintenance and overhaul become easy, the using period is prolonged, and the electrical switch cabinet pressure releasing device is more suitable for the operation demand of a conventional power system.

Description

A kind of cabinet pressure relief device and cabinet
Technical field
The utility model relates to a kind of pressure relief device.
Background technology
The middle part that at present a large amount of cabinets are employed in regulator cubicle is provided with pressure release passage, the such mode of pressure relief plate with little cylindrical void and blinds fenestra is installed on the passage carries out the pressure release processing.But in long-term use; Existence or foreign matter are fallen into the possibility in the pressure release passage through cylindrical void or fenestra, simultaneously because cylindrical void and fenestra are less, when short circuit accident; Door and cover plate before and after a large amount of gases can't and be washed open in the moment discharge cause secondary accident easily.
The utility model content
The purpose of the utility model provides a kind of pressure release cabinet pressure relief device and cabinet fast.
In order to realize above purpose, adopt following technical scheme: a kind of cabinet pressure relief device is characterized in that: said pressure relief device comprises the pressure release lid that is arranged on the cabinet pressure relief opening, and an end and the cabinet of pressure release lid fix, the other end and cabinet overlap joint.
The cabinet of said pressure release lid stiff end one side is provided with the barrier plate of restriction pressure release lid upset.
Said pressure release lid links to each other with cabinet through bolt or hinge.
A kind of cabinet of cabinet pressure relief device as stated that comprises is characterized in that: said pressure relief device is arranged at the cabinet top of regulator cubicle.
The utility model has been stopped original deficiency and defective; Change moment into by aperture and shutter discharging short trouble gas and go out and open flip mode original; Not only greatly improved the discharge capacity of equipment, also improved the degree of protection of product greatly, made Maintenance and Repair easier; Life cycle is longer, adapts to the operation needs of existing electrical network more.
Description of drawings
Fig. 1 is the structural representation of regulator cubicle in the utility model;
Fig. 2 is the enlarged drawing of A among Fig. 1;
Fig. 3 is the enlarged drawing of B among Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is further specified.
As depicted in figs. 1 and 2, a kind of regulator cubicle, the cabinet of regulator cubicle top is provided with pressure relief device, and pressure relief device comprises and is arranged at the lid of the pressure release on the pressure relief opening 12 on the cabinet, and an end of pressure release lid links to each other through hinge 3 with cabinet, and the other end and cabinet overlap.During normal the use, pressure release covers pressure relief opening, prevents that foreign matter from falling in the cabinet, has guaranteed that the interior equipment of regulator cubicle normally moves.When the needs pressure release, can open with a side of cabinet overlap joint, gas is discharged through pressure relief opening.This structure can be used repeatedly, and the effect of pressure release simultaneously is better.
As shown in figures 1 and 3; In switch cubicle, also add pressure relief device between top, cable vault and the switch gear room, the stiff end of pressure release lid is fixed on the cabinet through the steel double-screw bolt; And a side of stiff end also is provided with carries out spacing barrier plate 4 to the pressure release lid; When pressure release when upset lid, undertaken spacingly by barrier plate, avoid the electric of top caused damage.
More than show and described the advantage of basic principle, major technique characteristic and the utility model of the utility model.The utility model is not restricted to the described embodiments, the principle of describing in the foregoing description and the specification that the utility model just is described., all belong in the scope of the utility model technical scheme any simple modification, equivalent variations and modification that above embodiment did according to the technical spirit of the utility model.
