[0003] In the current actual operation process, the grounding wires used in the existing substations are of the turnbuckle type. When the grounding wire is added, the operator must forcefully hold the grounding wire to the hanging point to perform the turnbuckle, otherwise It will lead to incomplete contact between the hanging grounding wire and the grounding point, so that the grounding resistance does not meet the requirements, and improper force may cause the grounding wire terminal to slip, posing a threat to the personal safety of the staff. At the same time, the operator is wearing insulating gloves. It is very inconvenient to rotate the grounding wire under the condition of

The invention discloses a ground wire assembly which comprises a main rod body and an auxiliary rod body. A fixed clamp matched with a wiring terminal is arranged at the top end of the main rod body, a movable clamp matched with the fixed clamp in a clamped mode is arranged at the top end of the auxiliary rod body, a guide hole is formed in the fixed clamp in the axial direction of the main rod body in a penetrating mode, and the tail end of the movable clamp is installed in the guide hole in a slidable inserted mode and hinged to the top end of the auxiliary rod body; an operating rod is hinged to the tail end of the main rod body, a locking groove is formed in the middle of the operating rod, and a locking pin hinged to the tail end of the auxiliary rod body is slidable arranged in the locking groove. According to the ground wire assembly, the connecting structure is safe and reliable, and the operation process is simple, convenient and easy to carry out.
Description
technical field [0001] The invention relates to the technical field of supporting equipment for erection and maintenance of power transmission and transformation lines, in particular to a ground wire assembly. Background technique [0002] In the daily operation and maintenance of substations, most operations require power outages, so adding ground wires to equipment that has been powered off is one of the common operations in substation operation and maintenance. [0003] In the current actual operation process, the grounding wires used in the existing substations are of the turnbuckle type. When the grounding wire is added, the operator must forcefully hold the grounding wire to the hanging point to perform the turnbuckle, otherwise It will lead to incomplete contact between the hanging grounding wire and the grounding point, so that the grounding resistance does not meet the requirements, and improper force may cause the grounding wire terminal to slip, posing a threat to...
