Description
Technical field
The present invention relates to switch cubicle technical field, be specifically related to that a kind of switch cabinet grounding switch with heat sinking function is counter to be closed
Locking device.
Background technology
Earthed switch, when inspection switch cabinet, can first be closed a floodgate by switch cubicle operator, switch cubicle back shroud of then dismantling
Carry out correlation test and maintenance.Owing to earthed switch is "on" position, switch cubicle entirety is ground connection, so at this time operator
Member is safe, if now by grounding switch tripping, it is possible to circuit breaker cart is shifted onto operating position and closes a floodgate, cause out
Closing that cabinet major loop is charged or the anti-power transmission of cable, at this moment operator can be in breakneck condition.Further, switch cubicle makes
The heat produced during with cannot reasonably be got rid of, and greatly reduces the service life of switch cubicle.
Chinese patent CN201320820991.9 discloses a kind of switch cabinet grounding switch backlocking device, including switch cubicle
Side plate, described switch cubicle side plate is provided with U-shaped plate, and the described left vertical plane of U-shaped plate is provided with square shaft, and described square shaft is provided with breach；
Described square shaft right-hand member is provided with circular shaft, and described circular shaft is through the right vertical plane of U-shaped plate.A kind of switch cabinet grounding switch of the present invention is counter to be closed
Locking device, after switch cubicle back shroud assembles, the breach of square shaft exposes outside U-shaped plate, and now square shaft will not stop switch cubicle
Connecting lever on the big axle of ground connection, operable grounding switch tripping；When back shroud is removed, the breach on square shaft is in the effect of spring
Under move in U-shaped plate, now operation switch-cabinet grounding big axle time can by square shaft stop connecting lever motion, earthed switch just cannot
Separating brake, therefore ensures that the personal safety of operator.When switching in-cabinet temperature and needing to distribute, heat radiation must be additionally set
Heat is reasonably got rid of by device, uses very inconvenient.
Summary of the invention
For overcoming drawbacks described above, it is an object of the invention to provide the switch cabinet grounding switch backlocking dress that a kind of combination is present
Put, can be while to switch cabinet grounding switch backlocking, moreover it is possible in use switch in-cabinet temperature is rationally arranged
A kind of switch cabinet grounding switch backlocking device with heat sinking function removed.
A kind of switch cabinet grounding switch backlocking device with heat sinking function, erects including U-shaped plate, circular shaft, the U-shaped plate right side
Face, back-up ring, spring, square shaft, switch cubicle side plate, switch cubicle back shroud, connecting lever, left vertical plane, big axle.U-shaped plate is arranged on switch cubicle
On side plate, the left vertical plane of U-shaped plate has a square opening, square shaft is installed in square opening, square shaft has breach；Square shaft
Right-hand member is fixedly connected with circular shaft, and circular shaft is through the circular shaft hole on the right vertical plane of U-shaped plate；Back-up ring is installed on square shaft, square shaft, back-up ring with
Spring is installed between left vertical plane.Switch cubicle back shroud is positioned at the low order end of whole device；Connecting lever is connected on square shaft through big axle
Between breach.Left vertical plane is symmetrical arranged with right vertical plane.Big axle is arranged on relevant position, switch cubicle side plate lower end.This backlocking device
Also include heat sink, cover plate, fire retardant insulating plate；Heat sink is arranged on relevant position, cover plate lower end.The uniform row of being provided with on cover plate
Pore, is positioned at the top of whole device.Fire retardant insulating plate is arranged on the bottom of whole device.
The present invention has the switch cabinet grounding switch backlocking device of heat sinking function: is not only therefore prevented from back shroud and does not installs
Time grounding switch tripping, it is ensured that the personal safety of operator.By improving, fill in original switch cabinet grounding switch backlocking
Put increase heat sink, cover plate, fire retardant insulating plate, be extremely improved in original device and the temperature in switch cubicle cannot have been entered
The technical problem that row is rationally got rid of.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram；
Fig. 2 is switch cubicle back shroud mounted configuration schematic diagram of the present invention；
Fig. 3 is square axle structure schematic diagram of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings；
A kind of switch cabinet grounding switch backlocking device with heat sinking function as shown in Figure 1, Figure 2, Figure 3 shows, including U-shaped plate 1,
Circular shaft 2, the right vertical plane of U-shaped plate 3, back-up ring 4, spring 5, square shaft 6, switch cubicle side plate 7, switch cubicle back shroud 8, connecting lever 9, left vertical plane
10, big axle 11.U-shaped plate 1 is arranged on switch cubicle side plate 7, the left vertical plane of U-shaped plate 1 has a square opening, in square opening
Square shaft is installed, square shaft has breach；Square shaft 6 right-hand member is fixedly connected with circular shaft 2, and circular shaft 2 passes on the U-shaped right vertical plane of plate 13
Circular shaft hole；Back-up ring 4 is installed on square shaft 6, spring 5 is installed between square shaft 6, back-up ring 4 and left vertical plane 10.Switch cubicle back shroud 8
Low order end in whole device；Connecting lever 9 is connected on square shaft breach through big axle 11.Left vertical plane 10 is symmetrical with right vertical plane 3
Arrange.Big axle 11 is arranged on relevant position, switch cubicle side plate 7 lower end.This backlocking device also includes heat sink 12, cover plate 13, resistance
Combustion insulation board 14；Heat sink 12 is arranged on relevant position, cover plate 13 lower end.Uniform on cover plate 13 it is provided with steam vent, is positioned at whole
The top of device.Fire retardant insulating plate 14 is arranged on the bottom of whole device.
The present invention has the switch cabinet grounding switch backlocking device of heat sinking function, in use: when switch cubicle back shroud 8
When being assembled on switch cubicle, circular shaft 2 right-hand member is promoted to left movement by back shroud 8, circular shaft 8 movement progress square shaft 6 to left movement, when
When back shroud 8 covers completely, the breach on square shaft 6 exposes the outside at U-shaped plate 1, and now operational grounding switchs big axle 11, big axle
Connecting lever 9 on 11 is not by the stop of square shaft 6, it is achieved grounding switch tripping operates；After pulling down back shroud 8, in the elasticity of spring 5
Under promotion, square shaft 6 moves right, and the breach on square shaft 6 moves to inside U-shaped plate 1, now stops on big axle 11 due to square shaft 6
Connecting lever 9 rotate, earthed switch cannot by operation separating brake, be therefore prevented from grounding switch tripping when back shroud 8 is not installed, work as switch
When in cabinet, generation temperature needs to get rid of, heat sink 12, fire retardant insulating plate 14 temperature produced is by the aerofluxus on cover plate 13
Hole comes out.
The present invention has the switch cabinet grounding switch backlocking device of heat sinking function: is not only therefore prevented from back shroud and does not installs
Time grounding switch tripping, it is ensured that the personal safety of operator.By improving, fill in original switch cabinet grounding switch backlocking
Put increase heat sink, cover plate, fire retardant insulating plate, be extremely improved in original device and the temperature in switch cubicle cannot have been entered
The technical problem that row is rationally got rid of.
