Technical Field
[0001] The utility model relates to the technical field of grounding wire clamps, in particular to a safety grounding wire clamp. Background Art
[0002] The grounding wire is a safety device used to temporarily short-circuit and ground the power-off equipment. Its function is to prevent the sudden power supply of the equipment and the induced voltage of the adjacent high-voltage live equipment from causing harm to the human body when the high-voltage equipment is shut down for maintenance or other work, and to discharge the residual charge of the power-off equipment. During the installation, maintenance and overhaul of electrical equipment and systems, grounding operation is an important step to ensure the safety of workers. The grounding wire clamp is a key tool for grounding operation. Its safety and ease of use are directly related to the efficiency and safety of the grounding operation. The traditional grounding wire clamp has a single structure and does not clamp the cable end firmly. It is easy to fall off during use, which brings great safety hazards to the power maintenance project. Therefore, it is necessary to design a safe grounding wire clamp. Utility Model Content
