In the prior art, pressure release direction is direction, cabinet top, and pressure release window is a rectangle metal top plate, and side iron screw is fixed, and opposite side nylon screw is fixed.When breaking down in cabinet, roof deformation is opened, release pressure and vented gasses, and after pressure release, top board is scrapped, and could again put into operation after need changing.
Utility model content
For the problem of scrapping after overcoming existing pressure relief plate release pressure, the utility model provides a kind of structure high-tension switch cabinet with collapsible pressure relief plate simple, easy to use, by the pressure relief plate of monoblock is divided into polylith daughter board hinged successively, significantly can slow down the amplitude of deformation of pressure relief plate, realize the recycling of pressure relief plate.
A kind of high-tension switch cabinet with collapsible pressure relief plate, comprise the cabinet that top has pressure relief opening, described pressure relief opening place is coated with pressure relief plate, and the side of described pressure relief plate is hinged on cabinet, opposite side is inserted in the groove at cabinet top, and the top side plate of groove upwards extends along slot opening direction; Described pressure relief plate is made up of at least two pieces of hinged successively daughter boards, and cabinet and pressure relief plate have the hold down gag cooperatively interacted.
In the prior art, pressure relief plate is hinged on the top of cabinet, and opposite side is fixed by nylon bolt, when breaking down in cabinet, produce high temperature and high pressure gas instantaneously, and the nylon bolt that fuses, pressure relief plate is under high pressure opened, and realizes earth pressure release and vented gasses, due under the impact of high pressure, bulge in the middle part of pressure relief plate, produce serious distortion, need again to change.
For above-mentioned technical problem, in the technical solution of the utility model: by the daughter board being divided into by pressure relief plate polylith hinged successively, adjacent two pieces of daughter boards are connected by rotating shaft, and rotating shaft is also equivalent to the reinforcement of pressure relief plate, effectively can alleviate the distortion of pressure relief plate, simultaneously, under the impact of pressure, after rotating shaft bulges, be equivalent to pressure relief plate "fold", the side of pressure relief plate is deviate from groove, realizes opening fast of pressure relief plate; During normal use, pressure relief plate is fixed on cabinet top by hold down gag, prevents dust or foreign material from falling in cabinet, ensures Electrical Safety.
As preferably, described pressure relief plate is made up of the daughter board that two pieces are hinged on rotating shaft both sides.Described hold down gag comprises rotating shaft and extends extension outside pressure relief plate, and through described extension and the nylon bolt of threaded engagement in cabinet.
When pressing plate is made up of two pieces of daughter boards, the middle part of pressure relief plate is fixed on cabinet, and hold down gag now comprises extension and the nylon bolt of rotating shaft, and when breaking down, nylon bolt fuses, and bulges, thus open pressure relief plate in the middle part of pressure relief plate.
For convenience of the installation of nylon bolt, described extension is flat, and the sectional dimension of extension is greater than the sectional dimension at other positions, with the relative position of fixed rotating shaft and daughter board, prevents daughter board to be subjected to displacement along rotating shaft.
As preferably, described rotating shaft has the extension of extending outside pressure relief plate, and described hold down gag comprises the U-shaped seat inserted for extension, described U-shaped seat is inserted with the easily broken pin coordinated with extension.
U-shaped seat is also fixed on cabinet by nylon bolt, and the extension of rotating shaft is stretched in U-shaped seat, and easily broken pin is used for the position of fixed rotating shaft, and the middle part fluting of easily broken pin, under the high pressure of cabinet, rotating shaft breaks pin and carrys out release pressure.
As preferably, described pressure relief plate has three pieces of daughter boards, cabinet has the spring bearer plate acting on middle part daughter board.
When pressure relief plate has three pieces and above daughter board, except the daughter board on both sides, the daughter board at middle part is all fixed by identical parts and cabinet, can select nylon bolt, the utility model adopts the daughter board in the middle part of spring bearer plate compression pressure relief plate, and described spring bearer plate is arranged on cabinet by Coupling Shaft, in this Coupling Shaft, cover has wind spring, when the pressure suffered by daughter board is greater than the elastic force of wind spring, daughter board can wash the constraint of spring bearer plate open, realizes the unlatching of pressure relief plate.
The utility model structure is simple, is convenient to install, and fail safe is good, by the pressure relief plate of monoblock is divided into polylith daughter board hinged successively, significantly can slows down the amplitude of deformation of pressure relief plate, realize the recycling of pressure relief plate.
