The device reduces the labor intensity of operators in the process of installing and removing the grounding wire. , improve the work production efficiency, ensure the good contact between the grounding wire and the short-circuit grounding equipment, and provide a safer, more effective and more convenient sustainable development method for the power outage operation, maintenance and construction of the 10kV overhead line of the distribution network. .

The device of the utility model comprises a wire hook, a locking slider, a guide seat, a screw rod, a grounding wire, an insulating operating rod, and an electric wrench joint. The upper end of the rod, the other end of the screw is fixedly connected with the locking slider, and the locking slider is arranged on one side of the wire hook; one end of the grounding wire is fixedly connected with the wire hook, and the other end is the grounding end; the electric wrench joint is fixed at the lower end of the insulating operating rod.

The electric wrench joint is matched with the electric wrench to drive the insulating operating rod to rotate, and the rotation of the insulating operating rod drives the screw rod to rotate freely in the guide seat, thereby driving the locking slider to move up and down, so that the locking slider is close to or away from the wire hook up

The bottom of the insulating operating rod is provided with an installation hole, the electric wrench joint is provided with a convex block, the installation hole is matched with the convex block, and the electric wrench joint is fixed on the lower end of the insulating operating rod through the convex block.

After the grounding end of the grounding wire is well connected to the grounding body, use the insulating lever to hang the wire hook on the 10kV overhead bare wire or grounding test ring that needs to be shorted to ground, insert the rotating head of the electric wrench into the electric wrench connector, press The lower electric wrench tightens the switch to drive the insulating operating rod to rotate. Since the guide seat is fixed, the insulating operating rod drives the screw to rotate, so that the connected locking slider moves rapidly toward the wire hook, so that the 10kV overhead bare wire that needs to be shorted to ground is short-circuited. Or the grounding ring is locked and fixed between the wire hook and the locking slider to achieve the purpose of short-circuit fixation. When removing, insert the rotating head of the electric wrench into the electric wrench connector, and press the electric wrench to loosen the switch to drive the insulation. The operating rod rotates in the reverse direction. Since the fixed seat is fixed, the insulating operating rod drives the screw to rotate, so that the connected locking slider moves downward rapidly, so that the wire or the grounding test ring between the wire hook and the locking slider is loosened. After opening, use the insulating operating rod to remove the wire hook from the 10kV overhead bare wire or grounding inspection ring that is short-circuited and grounded, and untie the grounding end of the grounding wire.

Compared with the prior art, the advantages and technical effects of the present utility model are as follows:

1. This device uses an electric wrench to cooperate with the installation and disassembly of the three-phase short-circuit grounding wire of the 10kV overhead line of the distribution network. The operator consumes less physical strength and takes less time, reduces the labor intensity of the operator, and reduces the risk of falling objects and personnel falling from high altitude. 2. In addition, in order to ensure the good grounding, the operator needs to manually rotate the operating lever to make the grounding wire in close contact with the grounded equipment, and the operator consumes a lot of physical strength during operation. The ground wire is not in good contact with the grounded equipment, and there is a risk of personal electric shock.

The device has a simple structure, which can not only effectively shorten the working time, but also greatly reduce the labor intensity of the staff's operation, and at the same time improve the safety of the grounding operation. The professional field of power distribution has great use value and promotion significance.
