Description
All as the field of technology
The utility model relates to an electric power overhauls equipment technical field, concretely relates to earth connection management and control system.
All the above-mentioned background techniques
The grounding wire is one of the most important devices and safety measures for electric power maintenance, and plays an important role in ensuring the personal safety of maintenance personnel. The two ends of the grounding wire are respectively a grounding end used for being connected with the grounding wire pile and a line end used for being connected with the conductor, the grounding end is provided with a grounding end wire clamp, and the line end is provided with a line end wire clamp. However, personal and equipment safety accidents caused by improper hanging and dismounting of the grounding wire occur occasionally, and the fundamental reason is that a technical means for effectively controlling the grounding wire is lacked.
At present, the electric five-prevention system and some ground wire management and control systems consider that the ground wire grounding end is connected with or detached from the ground wire pile, so that the grounding wire is considered to be hung or detached.
