technical field

The invention belongs to the technical field of electric equipment, and in particular relates to a flexible electromagnetic power type operating lever and a method.

Background technique

According to Section 7.4.9 of "State Grid Corporation's Electric Power Safety Work Regulations (Transformation Part)": the grounding wire should be connected to the grounding terminal first, followed by the conductor terminal. The grounding wire should be in good contact and the connection should be reliable. The sequence for removing the ground wire is reversed. Insulating rods and insulating gloves should be used for installation and disassembly of the conductor end of the ground wire.

The insulating rod is the operating rod (also known as the grounding gun), which is a tool that must be used by electric power workers in the process of flipping the switch and hooking up the grounding wire. The traditional grounding clip is generally of a spring-loaded type, and the buckle head in the spring-loaded grounding clip can move relative to the frame to leak out of the clip nozzle. The traditional operating lever is driven by metal meshing teeth, which are prone to corrosion and dislocation, resulting in unreliable meshing and mechanical jamming.
