Technical Field

[0001] The invention relates to the technical field of electric tools, and in particular to a grounding wire hanging rack for pole work and a use method thereof. Background Art

[0002] 10kV distribution network line grounding wire is mainly used in the power system for the equipment and lines that have been powered off in the distribution network overhead line. It can effectively prevent the accidental voltage at the work location from harming the personal safety of the staff. It is an important tool for the safety lifeline of the power production workers in the distribution network.

[0003] At present, the grounding wire used in 10kV lines consists of a grounding pin, a grounding wire, and three double-tongue grounding rods. The grounding pin has a diameter of 16mm and a length of 0.8m. The grounding wire is 25mm. 2 Multi-strand soft copper wire with transparent soft plastic outer sheath, length 3*1.5m+22m; 3 double-tongue grounding rods, each of which is 1.14m long; when installing the ground wire on the overhead line, the operator carries a tester to verify that the line is indeed powered off, and then the ground staff uses a transfer rope to pass the double-tongue grounding rod with the grounding needle well grounded to the operator, and then hangs the ground wire phase by phase. The order is reversed when removing the ground wire;

[0004] According to the regulations: "When installing or removing the grounding wire, the grounding wire must not be touched." During power construction or power outage maintenance work, there is a lack of a dedicated location or platform for storing the grounding wire when installing or removing the grounding wire on the pole. Workers often touch the grounding wire during the process of installing or removing the grounding wire on the pole, which poses a great personal safety hazard. At the same time, due to the heavy weight of the grounding wire itself, workers will become tired when holding the grounding wire due to excessive weight on their arms, which affects the quality and efficiency of work and is not conducive to standardized operations. Therefore, the present invention proposes a grounding wire hanging rack for pole work and a method of using the same to solve the problems existing in the prior art. Summary of the invention
