Description
Technical field
This utility model belongs to high voltage electric equipment switch cubicle technical field, particularly to a kind of earthed switch back door tripper.
Technical background
Along with switch cubicle extensive use in power system, to switch cubicle safe efficient overhaul and become the new problem that maintainer faces.Earthed switch is an important ring of switch cubicle electrical safety.Traditional switch cubicle is when interruption maintenance, and switch cubicle, usually because earthed switch closes a floodgate not in place, thus causing can not directly opening back door, is carried out big dismounting only by special tool(s) by switch cubicle.This method not only danger is relatively big, and compares waste of manpower and time, it is impossible to raise labour productivity, and especially when switch cubicle batch is bigger, this defect is especially prominent.Switch cubicle is carried out big dismounting simultaneously and also easily causes the damage of switch cubicle, increase the workload of maintainer.
Therefore need badly in the middle of prior art and want a kind of novel technical scheme to solve this problem.
Utility model content
Technical problem to be solved in the utility model is: provide a kind of earthed switch back door tripper, it is used for solving traditional switch cubicle when interruption maintenance, switch cubicle is usually because earthed switch closes a floodgate not in place, thus causing can not directly opening back door, only by special tool(s), switch cubicle is carried out big dismounting, increase the workload of maintainer, it is impossible to the problem raised labour productivity.
A kind of earthed switch back door tripper, it is characterized in that: include grounding shaft, interlocking shaft, bolt, one end of described grounding shaft is connected with the ground wire in switch cubicle, the other end end face of grounding shaft is provided with double-layer circular mesa-shaped groove, and the diameter of the round table-like groove of outer layer is more than the diameter of the round table-like groove of internal layer, and the medial wall of the round table-like groove of internal layer is provided with female thread；
Described interlocking shaft is two rectangular slabs and " H " shape structure of hollow cylinder composition, and the middle part of two rectangular slabs is provided with through hole, this through hole with the hollow connection of hollow cylinder,
One rectangular slab groove round table-like with the outer layer of grounding shaft of interlocking shaft is connected, and another rectangular slab of interlocking shaft is connected with the head of bolt；
After the through hole of the screw rod traverse interlocking shaft of described bolt, groove round table-like with the internal layer of grounding shaft is connected by threaded engagement, and the apical head of bolt is provided with " one " font or " ten " font groove.
Arranging rectangular through hole on earthed switch back door, this through hole is more than the rectangular slab cross section of interlocking shaft.
After the through hole that one rectangular slab of described interlocking shaft is arranged on earthed switch back door, 90-degree rotation, interlocking shaft is stuck on earthed switch back door.
By above-mentioned design, this utility model can bring following beneficial effect:
For shortcomings and deficiencies of the prior art, be in that to provide order of the present utility model a kind of safe and reliable, use scope wide there is the device that earthed switch back door unlocks.
This utility model has the advantages that this utility model simple in construction, easy to operate, interlocking shaft can pass through the instruments such as screwdriver and unclamp bolt outside switch cubicle easily, interlocking shaft is made to separate with grounding shaft, open cabinet door and carry out big dismounting without to switch cubicle, greatly improve safety and the labor productivity of maintainer.
Accompanying drawing illustrates:
Below in conjunction with embodiment and accompanying drawing, this utility model is described in further detail
Fig. 1 is the structural representation of a kind of earthed switch back door of this utility model tripper.
Fig. 2 is the side-looking structural representation of a kind of earthed switch back door of this utility model tripper.
Fig. 3 is the plan structure schematic diagram of a kind of earthed switch back door of this utility model tripper.
1-grounding shaft, 2-interlocking shaft, 3-bolt in figure.
Detailed description of the invention
As shown in the figure, a kind of earthed switch back door tripper, it is characterized in that: include grounding shaft 1, interlocking shaft 2, bolt 3, described one end of grounding shaft 1 is connected with the ground wire in switch cubicle, the other end end face of grounding shaft 1 is provided with double-layer circular mesa-shaped groove, and the diameter of the round table-like groove of outer layer is more than the diameter of the round table-like groove of internal layer, and the medial wall of the round table-like groove of internal layer is provided with female thread；
Described interlocking shaft 2 is two rectangular slabs and " H " shape structure of hollow cylinder composition, and the middle part of two rectangular slabs is provided with through hole, this through hole with the hollow connection of hollow cylinder,
One rectangular slab groove round table-like with the outer layer of grounding shaft 1 of interlocking shaft 2 is connected, and another rectangular slab of interlocking shaft 2 is connected with the head of bolt 3；
After the through hole of the screw rod traverse interlocking shaft 2 of described bolt 3, groove round table-like with the internal layer of grounding shaft 1 is connected by threaded engagement, and the apical head of bolt 3 is provided with " one " font or " ten " font groove.
Arranging rectangular through hole on earthed switch back door, this through hole is more than the rectangular slab cross section of interlocking shaft 2.
After the through hole that one rectangular slab of described interlocking shaft 2 is arranged on earthed switch back door, 90-degree rotation, interlocking shaft 2 is stuck on earthed switch back door.
When occurring because earthed switch closes a floodgate not in place, thus causing when the situation that can not directly open back door occurs, the instruments such as screwdriver can be passed through outside cabinet, unclamp bolt 3 easily, interlocking shaft 2 is made to separate with grounding shaft 1, open back door and carry out big dismounting without to switch cubicle, greatly improve safety and the labor productivity of maintainer, reduce the labor intensity of maintainer.
