The invention discloses a grounding wire with the anti-misoperation locking function. The grounding wire comprises a conductor wire clamp which is disposed at a corresponding position of a line, and the conductor wire clamp is connected with a grounding device through a wire. The grounding wire is characterized in that, a servo motor, positioned on the side of a hanging inlet, is arranged on the conductor wire clamp. A single-chip microcomputer is arranged on the servo motor and is used for controlling the servo motor to work. An output shaft of the servo motor is connected with a locking rod.In the initial state, the locking rod closes the hanging inlet. A locking control circuit is arranged in the grounding device and can send a signal to the single chip microcomputer after being conducted through a grounding bolt. In this way, the servo motor drives the locking rod to rotate, and the unlocking purpose is achieved. According to the grounding device, the locking control circuit in the grounding device can be used for controlling whether the hanging inlet in the conductor wire clamp is opened or not. The grounding device is simple in structure, and the mutual locking can be realized. The occurrence of misoperation events caused by sequence errors during grounding wire assembling and disassembling can be avoided. The operation safety is ensured.
