Description

Technical Field

[0001] The utility model relates to the technical field of electric power operation equipment, and specifically discloses a clamping device for grounding wire installation operation. Background Art

[0002] The grounding wire is also called the safety return line. The grounding wire is connected to the outer casing of the electrical equipment and other parts. In an emergency, it can lead the unsafe charge or leakage current out of the main line of the electrical equipment. On the one hand, it can protect the equipment, and on the other hand, it can avoid damage to the power workers. At present, in order to facilitate the wiring operations of power workers, copper braided belt grounding wires have been widely used in power operations. The outer periphery of the copper braided belt grounding wire is made of stainless steel and galvanized steel wire, so that the grounding wire has strong corrosion resistance, wear resistance, and oxidation resistance. It is not easy to corrode and rust during use, and can maintain good conductivity and grounding performance for a long time; therefore, the copper braided belt grounding wire is widely used in various places such as power equipment, communication equipment, aerospace equipment, chemical industry, oil and coal mines, hospitals, etc.

[0003] Copper braided grounding wires are often assembled into wire rollers. When installing grounding wires, power workers need to carry wire rollers. Power workers need to cut copper braided grounding wires that match the required length according to different power operation scenarios. Then, power workers fasten and install wiring terminals at both ends of the copper braided grounding wires to install the grounding wires. In the above power operation process, since the copper braided grounding wires are bent and wound in the wire rollers, in order to ensure the accuracy and safety of the grounding wire installation, power workers often need to manually straighten the copper braided grounding wires before cutting them, so as to avoid contact with other electrical equipment due to the bending of the copper braided grounding wires. It can be seen that manually straightening the copper braided grounding wires greatly limits the work efficiency of power workers, and after long-term work, the workers can obviously feel a high degree of fatigue.
