Abstract

The invention discloses a high-voltage insulating overhead ground wire short-coupling device. The high-voltage insulating overhead ground wire short-coupling device comprises a casing, a driving bevel gear, a driven bevel gear, an auxiliary transmission bar which is coaxially connected with the driven bevel gear, a rotary holding rod used for driving the driving bevel gear to rotate, and a clamping structure arranged on the casing. The rotary holding rod is coaxially connected with the driving bevel gear, the driving bevel gear is engaged with the driven bevel gear, the auxiliary transmission bar is rotatably connected with the casing, the clamping structure comprises a vertical screw, a clamping base and a metal hook member, the metal hook member comprises a hook base which is in screw-thread fit with the vertical screw, a hook arranged above the clamping base, and a connector used for connecting the hook base with the hook, the connector is provided with a short-coupling wire, and the connector is in slip connection with the clamping base. Beneficial effects of the high-voltage insulating overhead ground wire short-coupling device are that the short-coupling device is reasonable in structure, and can be hung on the insulating overhead ground wire, the locking and unlocking operations are convenient, the high-voltage insulating overhead ground wire can be fixed firmly, the short-coupling device is good in stability during the working process, and the safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of high-voltage operation auxiliary tools, and in particular relates to a high-voltage insulation overhead ground wire short-circuit device. Background technique [0002] The line safety regulations stipulate that when working on high-voltage lines, the insulated overhead ground wire should be regarded as a live body, and when it is necessary to work on the insulated overhead ground wire, it should be reliably grounded. Due to different voltage levels and tower shapes of the existing insulated overhead ground wires, the lengths of the tools used to connect the insulated overhead ground wires and the cross-arm are also different. The length of the tool for connecting the insulated overhead ground wire and the cross arm of the 220kV voltage level tension tower is 1.1-1.3m, and the length of the fittings for connecting the insulated overhead ground wire and the cross arm of the 500kV voltage level tension tower is about ...
