Description
Technical field
The present invention relates to a kind of GGD type low-voltage distribution cabinet cabinet top pressure relief device.
Background technology
General power distribution cabinet or switch cubicle must configure pressure relief device, and existing pressure relief device mostly is one and covers and joining
Metallic plate at electricity cabinet or switch cubicle pressure relief opening, this structure generally metallic plate directly covers the groove at pressure relief opening
In；Or the side of metallic plate is by patch screw and power distribution cabinet or switch cubicle is fixed, opposite side passes through nylon spiral shell
Nail is fixed with power distribution cabinet or switch cubicle, and during pressure release, the high-temperature gas in power distribution cabinet or switch cubicle is by nylon screw
Fusing makes metallic plate loosen, and then the high-temperature gas in power distribution cabinet or switch cubicle is by metallic plate jack-up, the highest
Wet body releases from pressure relief opening.Said structure there is problems in that 1, directly covers pressure relief opening due to metallic plate,
Or using screw to connect, screw easily loosens, and GGD type low-voltage distribution cabinet is during unloading, such as steel wire rope
The method mistake of hanging causes cabinet gradient, aloft encounters barrier and cause tank leaning to add some in operation
Crane operation person operates reason and causes cabinet to rock seriously, and these are all likely to result in cabinet top pressure relief device web plate and exist
Drop in the air, bring serious hidden danger to personal safety；2, GGD type low-voltage distribution cabinet is during in place,
Due to passage reason, make cabinet fall cabinet pass through, during cabinet, owing to direction is got wrong, usually make cabinet top
Pressure relief device web plate splits away off on the body pounding people from groove, particularly head；3, GGD type low-voltage distribution
Cabinet, during spelling cabinet, overexerts due to anthropic factor or cabinet one side frame is at channel-section steel, and the non-frame of opposite side exists
During channel-section steel, these are all likely to result in tank leaning, make cabinet pressure relief device web plate split away off from groove, pound
Particularly head on the health of people；4, very big at groove clearance due to pressure relief device web plate, in the middle of in place,
Or cabinet is by the biggest percussion vibration, makes pressure relief device web plate side come off in groove, rides on 0.4kV bus,
Not discovering if checked and accepted, due to 0.4kV busbar short-circuit during power transmission, will result in serious equipment breakdown；5, when
When using screw to connect, metallic plate is installed and is shirked equal inconvenience；6, when after power distribution cabinet or switch cubicle pressure release, join
Screwed hole on electricity cabinet or the switch cubicle nylon screw that also easily wire damages or is melted blocks, and is difficult to peace
Fill new metallic plate；7, when, after each power distribution cabinet or switch cubicle pressure release, metallic plate all can be deformed, every time
Be required for the metallic plate more renewed, cause maintenance cost increase.
Summary of the invention
The technical problem to be solved is to provide a kind of GGD type low-voltage distribution cabinet cabinet top pressure release dress
Putting, by arranging mesh on pressure relief plate, during pressure release, the high pressure gas part in power distribution cabinet is released from mesh,
Can reduce the instantaneous pressure that pressure relief plate is subject to, reduce the deformation probability of pressure relief plate, pressure relief plate passes through with power distribution cabinet
Hasp is fixing to be connected, fixation, convenient disassembly, it is possible to decrease human casualty accident rate, reduction electrical equipment
Accident rate and raising power supply reliability.
For solving above-mentioned existing technical problem, the present invention uses following scheme: a kind of GGD type low-voltage distribution
Cabinet cabinet top pressure relief device, including the pressure relief plate being arranged at the pressure relief opening of power distribution cabinet top, described pressure relief plate with join
Electricity cabinet connects by hasp is fixing, and described pressure relief plate has some mesh.
As preferably, the area of described mesh is sequentially reduced to the right from the left side of pressure relief plate.When power distribution cabinet occurs
Or during switch cubicle pressure release, owing to right side mesh is less, this side pressure relief plate impact force is relatively big, and this side is first
Departing from power distribution cabinet, it is controlled that pressure relief plate starts path, it is possible to decrease human casualty accident rate, reduction electrical equipment thing
Therefore rate.
As preferably, described hasp includes that the first hasp and the second hasp, described first hasp are positioned at pressure relief plate
Left side, described second hasp is positioned at the right side of pressure relief plate, and described first hasp includes being arranged on power distribution cabinet
The pedestal on top and switching eccentric shaft on pedestal, described eccentric shaft is fixedly connected with handle, described eccentric shaft
Connect and have the first coupler body, described pressure relief plate is provided with the second coupler body for hooking together with the first coupler body, described
Second hasp includes the strip being arranged on power distribution cabinet top, and described strip has some circular holes and elongated hole, institute
State circular hole and elongated hole all runs through the upper and lower surface of strip, described circular hole and elongated hole one_to_one corresponding and one end of elongated hole
Running through the sidewall of circular hole, the top of described elongated hole is narrower than bottom, and the bottom surface of described pressure relief plate is provided with some and round
Hole cylinder one to one, the bottom of described cylinder connects spheroid, and the diameter of described spheroid is more than cylinder
Radial diameter, the diameter of the described spheroid top width more than elongated hole the bottom width less than elongated hole, described
Cylinder and spheroid are working of plastics.When pressure relief plate is installed, first spheroid is stretched into one to one circular hole, now
First coupler body and the second coupler body are corresponding, pull handle, and the second coupler body is pulled by the first coupler body to the left, pressure release
Plate is slightly moved to the left, and spheroid enters in elongated hole, and pressure relief plate fixation, during pressure release, cylinder or spheroid are by high temperature
Gas softens, simultaneously because the impulsive force on right side is relatively large, cylinder and spheroid fast fracture, pressure relief plate lifts
Rise and be able to pressure release, whole during, it is short that pressure relief plate starts the time, is unlikely to deform.
As preferably, described pressure relief plate being hinged with some cover plates, described cover plate and mesh one_to_one corresponding also cover
On mesh.Cover plate can play blocks dust and enter the situation of power distribution cabinet at mesh.
Beneficial effect:
The present invention uses a kind of GGD type low-voltage distribution cabinet cabinet top pressure relief device that technique scheme provides,
By arranging mesh on pressure relief plate, during pressure release, the high pressure gas part in power distribution cabinet is released from mesh, can subtract
The instantaneous pressure that little pressure relief plate is subject to, reduces the deformation probability of pressure relief plate, and pressure relief plate and power distribution cabinet pass through hasp
Fixing connection, fixation, convenient disassembly；I.e. reduce human casualty accident rate, reduce again and electrically set
Standby accident rate, improves power supply reliability.
