Description

10kV overhead line fixed-point installation grounding device

technical field

The utility model relates to the field of electric power maintenance. the

Background technique

At present, during spring and autumn inspections, many lines are shut down during power outage maintenance. When going out to work, the staff carry multiple sets of 10kV short-circuit grounding wires. Each set of grounding wires weighs about 20 catties, which is particularly inconvenient to carry. When hanging the ground wire, the ground wire is passed up and down, and it is easy to cause damage to the ground wire insulation rod. After the work is completed, the physical strength of the operator is too large. It is easy to fall off and cause damage to the ground rod. In addition, when the staff is hanging the ground wire, they often have the wrong operation of hanging the wire end first and then the ground end, which is prone to personal induction. When crossing and multiple parallel lines are connected to the ground wire, it is also easy to cause the wrong lever to be pushed, and the phenomenon of live wire hanging to the ground wire will occur. the

Utility model content
