In the power system, accidents involving live hooking of grounding wires or power transmission with grounding wires are not uncommon, and are listed as one of vicious misoperation accidents. The existing grounding wire clamp There is a clip body, a groove is arranged on the clip body, a through hole is arranged on the lower groove edge of the groove, a pull rod is arranged in the through hole, a movable splint is arranged in the groove, the movable splint is connected with the pull rod, and the pull rod is connected with the movable The connecting end of the splint is covered with a spring, and the other end is provided with a blocking cap and a connecting handle. The through hole and the pull rod are correspondingly provided with a chute and a pin. To open or close the edge of the groove, the clip body is provided with connection holes or bolts and other grounding wire connection devices. When in use, connect the large end of the operating rod to the connecting handle, and make the movable splint in an open state, and then place the clip body The side of the upper slot is hung on the grounded wire, and then the operating lever is rotated to make the pin enter the chute. Under the action of the spring, the movable splint is closed to clamp the wire. The disadvantage is that the operation is inconvenient, the error rate is high during the operation, and the wire In addition, due to the wide variety of substation equipment and the great differences in equipment, the installation of ground wires is not standardized and the installation of ground wires is difficult. For some equipment and installation locations, the existing ground wire clips cannot be installed at all. ; In some installation locations, because of the angle problem, the distance between the person and the grounded conductor cannot be guaranteed to meet the safety distance requirements during the process of installing the grounding wire, and electric shock accidents may occur.
