Description

Technical Field

[0001] The invention relates to an electric power assembly auxiliary device, in particular to a grounding electrode anti-detachment type connection clamp. Background Art

[0002] With the continuous development of the power system and the continuous increase in power demand, the performance requirements for grounding devices are becoming higher and higher. The grounding device consists of a grounding electrode, a grounding busbar, a grounding lead, a grounding card, a protective tube and other parts. The grounding electrode is the core part of the grounding device and is responsible for conducting current into the earth. The grounding electrode is usually buried vertically or horizontally underground and achieves current dispersion through contact with the soil. The grounding lead is used to conduct current from the grounding busbar into the ground, connecting the grounding busbar and the grounding electrode. The grounding card is used to fix and connect the grounding wire and the grounding electrode to ensure the reliability of the electrical connection and the stability of the mechanical fixation. When the grounding wire is connected to the grounding electrode through the grounding card, the grounding card is easy to detach from the grounding electrode under outdoor environmental factors or other external forces, making the grounding device ineffective and affecting the safety of the line.
