Description
Technical field
This utility model relates to a kind of Medium Voltage Switchgear cabinet pressure relief plate, is mainly used in middle pressure switchgear assembly.
Background technology
In electrical power distribution system, can the pressure release passage of switch cubicle effectively play pressure release effect, directly affects operator
Member's safety coefficient；Current domestic main in be pressed into set producer and use pressure relief plate structure as pressure release passage, general pressure relief plate is for long
Square metal plate, side iron screw is fixed, and fixes with nylon screw for one, nylon screw insufficient strength, and easy to fall off causing is let out
Pressing plate loosens, and affects pressure relief plate location and installation reliability, and relieving characteristics is unstable.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of Medium Voltage Switchgear cabinet pressure relief plate device, it is desirable to
Can effectively play pressure release effect, ensure operator's personal safety, and location and installation is reliable, relieving characteristics is stable.
Medium Voltage Switchgear cabinet pressure relief plate of the present utility model, is made up of pressure release top board, pressure release top cover, and pressure release top board is fixed
Being installed in the middle part of switch cabinet body top board, pressure release dome is loaded on above pressure release top board window；Pressure release top board window is forward and backward, right
Lateral edges has flanging composition U-shape structure upwards, and pressure release top cover four limit is respectively provided with downward flanging, pressure release top board window edge
The flanging downward with pressure release top cover of flanging upwards is nested against one another, and wherein left side flanging is additionally provided with fixed installation plate, pressure release top
The fixed installation plate of lid is fixed on switch cabinet body top board window together with pressure release top board left side；Described pressure release top cover is downward
Flanging inside with outside pressure release top board window edge flanging upwards mutually interference tensioner coordinate；The described U-shaped knot of pressure release top board
Structure is three angle steel compositions, and three angle steel are respectively and fixedly installed on switch cabinet body top board；Described pressure release top board window edge
Flanging upwards uses the backward upper bending of metallic plate punching to be fabricated by, and pressure release top board surrounding is fixed with switch cabinet body top board
Connect；Described pressure release top board window is provided with Air Filter.
Medium Voltage Switchgear cabinet pressure relief plate of the present utility model, uses pressure release top cover to rise friction tight with pressure release top board interference
Mode carries out location and installation, instead of nylon screw fixed form, can effectively play pressure release effect, and pressure release top cover pine will not occur
Dynamic obscission, improves operator's personnel safety factor, reduces cost, and location and installation is reliable, and relieving characteristics is stable.

Detailed description of the invention
As it can be seen, a kind of Medium Voltage Switchgear cabinet pressure relief plate, being made up of pressure release top board, pressure release top cover, pressure release top board is solid
Dingan County is loaded in the middle part of switch cabinet body top board, and pressure release dome is loaded on above pressure release top board window；Pressure release top board window is forward and backward,
Right side edge has flanging composition U-shape structure upwards, and pressure release top cover four limit is respectively provided with downward flanging, pressure release top board edge of window
The edge flanging upwards flanging downward with pressure release top cover is nested against one another, and wherein left side flanging is additionally provided with fixed installation plate, pressure release
The fixed installation plate of top cover is fixed on switch cabinet body top board window together with pressure release top board left side；Described pressure release top cover to
Under flanging inside with outside pressure release top board window edge flanging upwards mutually interference tensioner coordinate；Described pressure release top board is U-shaped
Structure is three angle steel compositions, and three angle steel are respectively and fixedly installed on switch cabinet body top board；Described pressure release top board edge of window
Edge flanging upwards may be used without the backward upper bending of metallic plate punching and is fabricated by, pressure release top board surrounding and switch cabinet body top
Plate is fixing to be connected；Described pressure release top board window is provided with Air Filter.
Medium Voltage Switchgear cabinet pressure relief plate of the present utility model, first above switch cabinet body top board, laying one layer is dust-proof
Net, is then placed in pressure release top board above Air Filter, then the fixed installation plate alignment pressure release will preset on the left of pressure release top cover afterwards
Without the direction of flanging on the left of top board window edge, pressure release top cover is loaded on outside the flanging of pressure release top board by four flanging covers, by
The flanging downward in pressure release top cover coordinates with the pressure release top board mutual interference of flanging upwards tensioner, thus pressure release top cover is the most fixed
Position is fixing, fixes connected mode finally by screw and pressure release top cover, pressure release top board, Air Filter are further secured to switch together
On cabinet cabinet top board, pressure release top board surrounding is adopted and is screwed that connected mode and switch cabinet body top board are fixing to be connected, installation
Complete.Medium Voltage Switchgear cabinet pressure relief plate of the present utility model is when switch cubicle is properly functioning, and pressure release top cover is rolled over pressure release top board
Expanding force and screw connection between limit provide dual fixing, and pressure release top cover loose or dislocation phenomenon will not occur；Switch cubicle occurs
During internal arcing fault, pressure release top cover can quick and complete be opened after gas expansion impact by cabinet.
