Description

Technical Field

[0002] According to the "Electrical Safety Work Regulations", when 10kV distribution lines and equipment are shut down for maintenance, the measures of "power outage, electricity testing and installation of grounding wires" must be implemented to ensure safety. The grounding wire (i.e. grounding device) is a wire that directly connects the power supply line to the earth. It can also be called a safety return line. It can directly introduce current into the earth to avoid the risk of electric shock. Nowadays, in the process of repairing distribution network failures, it is also necessary to connect the grounding wire. The current way of connecting the wires is to connect one end of the grounding wire to the distribution network, and then wrap the other end of the grounding wire around the node head on the upper side of the conductive pole through bolts, and then insert the conductive pole into the ground to achieve the connection of the grounding wire. However, when the conductive poles are used nowadays, they are mostly directly exposed to the outside world, which can easily cause workers to get electric shocks due to accidents. At the same time, the conductive poles are manually forced into the ground, and it is difficult to insert them into harder soil. Utility Model Content
