The equipment must be tested firstly between the hanging ground wires, and because the insulation rod must be used to contact the electroscope with the electrified equipment firstly during the test, at the moment, the insulation rod cannot be provided with the conductive ground wires, so that one-time grounding work is completed, operators must lift and put down the insulation rod for 2 times, the working steps are complicated, and the labor intensity of the operators is high.

In addition, the mode of hanging the grounding wire through the insulating rod is limited by the strength of a person and the bending resistance of the insulating rod, so that the grounding wire cannot adapt to the high operation requirement, and the phenomenon that the insulating rod is difficult to control exists. In a transformer substation operation field, a large number of live equipment exists, and an insulating rod with a cable is directly lifted by manpower, so that the risk of accident caused by mistakenly touching the live equipment exists.

In order to solve the above-mentioned problem that accomplishes a ground connection work, the operation personnel must carry out 2 times and lift, put down the work of insulator spindle, and work step is comparatively loaded down with trivial details, and personnel intensity of labour is big, this application provides an electroscope formula ground connection pincers action bars, and referring to the fig. 1, fig. 1 is a schematic structure diagram of an electroscope formula ground connection pincers action bars that this application shows an exemplary embodiment, includes:

The grounding clamp 200 is hung with an insulating rope 210, and the insulating rope 210 is used for being connected with a grounding wire and also used for pulling the grounding wire to the position of the grounding clamp 200 or pulling the grounding wire from the position of the grounding clamp 200. The insulating rope 210 is connected with the ground wire, and when the electroscope 100 contacts with the charging equipment and the working state of the electroscope 100 is confirmed, in order to ensure that the ground wire does not contact with the charging equipment, the ground wire can be placed on the ground, and the insulating rod is normally lifted for operation, so that the ground wire does not contact with the charging equipment. After confirming that the electroscope 100 functions properly, the insulator spindle 300 is not required to be put down and then connected with the ground wire, and the ground wire can be pulled to the position of the grounding clamp head 200 at the top of the insulator spindle 300 through the insulator cable 210 to directly contact with the bus bar.

Or, when the maintenance is completed and the power supply needs to be recovered to take down the grounding wire, the grounding wire can be pulled down from the grounding clamp head 200 through the insulating rope 210 and put back to the ground, and then the insulating rod 300 is put down, so that the operation is simple and quick, the insulating rod 300 does not need to be repeatedly lifted and put down, and the labor is saved.

Since the position of the fixed end 230 is unchanged, and accordingly, the position of the hanging tab 260 is also unchanged, only the contact end 240 moves up and down along with the rotation of the lead screw 220.

The contact end 240 is configured to: when the insulating rod 300 is rotated clockwise, the contact end 240 is close to the hanging lug 260, and when the insulating rod 300 is rotated counterclockwise, the contact end 240 is far away from the hanging lug 260.
