Problems solved by technology
But at present, these two forms have their own disadvantages. After the pull-type grounding wire is retracted, it needs to be bundled for easy portability. However, each person has different winding methods. Improper winding leads to disordered winding and dead knots, etc.; each insulating rod grounding wire has an insulating rod, which leads to a great increase in the weight of a set of grounding wires hanging on the tower, which is not conducive to the carrying operation of the staff

The invention relates to a portable telescopic power transmission line grounding wire, and belongs to the technical field of power transmission line maintenance in the power industry. The portable telescopic power transmission line grounding wire comprises a shell, a fixed shaft is arranged on the inner side of the shell, a rotary chuck is arranged on the fixed shaft, the rear part of the rotary chuck is connected with a coil spring through a connecting rod, the coil spring is arranged in the shell, the grounding wire is wound on the rotary chuck, a grounding wire upper outlet and a groundingwire lower outlet are respectively arranged at the top and the bottom of the shell corresponding to the rotary chuck, the grounding wire at the grounding wire upper outlet is connected with one side of a wire clamping clamp, the other side of the wire clamping clamp is connected with an insulating rope, the grounding wire at the grounding wire lower outlet is connected with a grounding end of thegrounding wire, a groove is formed in one side of the rotary chuck, a buckle is arranged on the shell in cooperation with the groove, the bottom of the buckle is hinged to the shell, the upper part ofthe buckle is connected with the shell through a spring, and an up-down sliding button is arranged on the shell corresponding to the buckle. The portable telescopic power transmission line groundingwire has good portable performance, can effectively improve the efficiency of hanging the grounding wire on a tower by workers, and shortens the overhaul period.
Description
technical field [0001] The invention relates to a portable retractable grounding wire of a power transmission line, which belongs to the technical field of power transmission line maintenance in the electric power industry. Background technique [0002] In recent years, the number of overhead transmission lines has increased, and the power outage maintenance work of transmission lines has become more and more frequent. For power outage maintenance work that requires contact with conductors, the staff must first install the grounding wire, and then contact the conductors. At present, during the maintenance of overhead transmission lines, there are mainly two types of grounding wires used: pull-type grounding wires and insulating rod grounding wires. There is a long insulating rope at the end of the clamp for the pull-type grounding wire. When installing, pull the insulating rope to make the clamp clamp the wire and form a loop with the earth. The insulating rod grounding wir...
