Description

Technical Field

[0001] The present invention relates to the technical field of maintenance and repair of high-voltage transmission lines, and particularly relates to a flexible and powerful bayonet-type remotely controlled high-voltage grounding device. Background Art

[0002] When maintenance and repair are required for high-voltage overhead transmission lines, the line segment needs to be powered off, and then the operating personnel hang grounding wires at both ends of the high-voltage transmission line to be maintained and repaired, so as to avoid harm to the on-site operating personnel due to accidental sudden power-on. Therefore, hanging the grounding wire is an important measure to ensure the personal safety of operating personnel during the maintenance and repair of high-voltage monitoring transmission lines, and it is also an important measure to prevent induced electric shock near the energized body or to ensure the personal safety of operating personnel when accidentally closing the switch.

[0003] At present, the grounding wire usually adopts a directly hung wire clamp. When in use, in order to make the contact between the wire clamp and the wire more firm, it is required that the insulating rod connected to the wire clamp is perpendicular to the wire or close to 90 degrees to meet the installation requirements of the grounding wire. However, when the operating personnel install the grounding wire, due to the limitations of the working environment, it is very difficult to make the insulating rod perpendicular to the wire or close to 90 degrees, resulting in an insecure contact between the grounding wire clamp and the wire. When the wire vibrates during the construction process, the grounding wire will become loose and break away from the wire, reducing the contact area between the grounding wire clamp and the wire, leaving a great potential safety hazard for the safety of electric power construction.
