Abstract
The utility model relates to a high -voltage switch field has especially involved a metal -enclosed cubical switchboard. Establish the cabinet body of high -pressure compartment in this metal -enclosed cubical switchboard includes, be equipped with the pressure release window of high -pressure compartment on the cabinet body to the department is equipped with the pressure release lid in the pressure release window, and the pressure release lid is including relative link that sets up and swing end, and is articulated between the link and the cabinet body, and the swing end department that the cabinet body was gone up at the pressure release lid is equipped with the pressure cap of pushing down swing end edge, and the pressure release lid can take place deformation when receiving set pressure and the cap is pressed in the slippage. Swing end it comes the slippage and press the cap through the pressure release lid deformation to take place, therefore pressure release lid corresponding the reducing in position that need to take place deformation can reduce the required power of deforming, in addition, because that adopt between the link of pressure release lid and the cabinet body is hinge structure, consequently, in case the swing is held by the unblock, then the pressure release covers and just can reach required size under the effect of atmospheric pressure to reach the effect that shortens the pressure release lid and open the required time.
Description
Technical field
The utility model relates to high-voltage switch gear field, has particularly related to a kind of metal closed switch cabinet.
Background technology
Metal closed switch cabinet is a kind of switchgear being applicable to the various distribution such as transformer station, power plant, industrial and mining enterprises, electricity consumption occasion, it is strong that it has breaking capacity, dynamic thermal stability is good, and electrical arrangement is flexible, the advantages such as serial, practical and floor space is little.
In the process used, interior unit cell model is the most serious fault that metal closed switch cabinet faces, electric arc can produce thermal effect and pressure effect, if cabinet design is unreasonable, in high temperature and high pressure gas and cabinet, parts may be spouting in cabinet, causes serious injury accident to operating personnel.Therefore present metal closed switch cabinet is designed with pressure release window and decompression cover at each high pressure compartment, and when there is internal arc, decompression cover is opened by gases at high pressure, and gas is discharged from pressure release window, thus protection operating personnel.
About structure and the assembling form of decompression cover, notification number is CN203445445U, involved by having in the Chinese patent specification of the day for announcing on February 19th, 2014, disclosed in this patent, decompression cover comprises lid body, lid body is rectangular structure, its left end bottom surface is provided with square breach (running through the groove of side, front and back), when assembling, the left end carbon steel bolt of lid body is fixed, ensure reliably fixing between lid body and cabinet, the right-hand member of lid body is fixed by plastic bolt, in use procedure, if met accident, the plastic bolt that then intensity is relatively poor is thrust instantaneously, lid body produces plastic deformation in its square indentation, there bending simultaneously, thus i.e. release burst gas can be reached, decompression cover can not be made again to fly out the effect of hurting sb.'s feelings, play the effect of protection operating personnel.
The application of above-mentioned decompression cover is comparatively extensive, but owing to needing when covering this body action to cut off plastic bolt, although the intensity of plastic bolt is more weak compared with carbon steel bolt, but it is still more difficult destroyed, the pressure which results in needed for the unlatching of pressure release window is larger, the problem that pressure release window cannot be opened in time may be caused, in addition, because lid body produces plastic deformation when action, therefore it is longer to open the required time, and in the process of opening, lid body once motion, pressure then in cabinet reduces instantaneously, be difficult to ensure enough pressure lid body is opened completely, lid body after opening, reset if want, then must occur again once to bend in its square indentation, there, easily this this place forms fatigue fracture, lid body is caused to reuse.
Utility model content
The purpose of this utility model is to provide a kind of metal closed switch cabinet, opens required pressure with the decompression cover reducing cabinet, shortens decompression cover and opens required time.
In order to solve the problem, metal closed switch cabinet of the present utility model is by the following technical solutions: metal closed switch cabinet, the cabinet of high pressure compartment is established in comprising, cabinet is provided with the pressure release window of high pressure compartment, and be equipped with decompression cover in pressure release window place, decompression cover comprises the link and swinging end that are oppositely arranged, hinged between link and cabinet, swinging end place at decompression cover on cabinet is provided with the pressure cap pushing down swinging end edge, and decompression cover deformation can occur when being subject to setting pressure and slippage pressure cap.
Described pressure cap is the pressure cap of point type distribution.
Swinging end place at decompression cover on cabinet is provided with bolt, and described pressure cap is made up of the bolt head of described bolt.
Described decompression cover is rectangular, and described link and swinging end are be made up of the end at the minor face place of decompression cover respectively.
The link of described decompression cover be provided with flanging and by described flanging and cabinet hinged.
The both sides adjacent with link of described decompression cover are respectively equipped with flanging.
Described decompression cover is located on the top board of cabinet.
Described pressure cap due to the cabinet of metal closed switch cabinet of the present utility model is the edge of the swinging end being pressed in decompression cover, and when decompression cover is subject to setting pressure, it carrys out slippage pressure cap by there is deformation, therefore decompression cover needs the corresponding reduction in position that deformation occurs, the power needed for deformation can be reduced, in addition, articulated structure due to what adopt between the link of decompression cover and cabinet, therefore, once swinging end is unlocked, then decompression cover just can reach required size under the influence of air pressure without letup, thus reach the effect shortening decompression cover unlatching required time.
