The invention relates to the technical field of ground rods, in particular to a ground rod torque limiting device. The ground rod torque limiting device comprises a torque limiter, a sleeve and a grip; the two ends of the torque limiter are connected with the sleeve and the grip respectively; the first end of the sleeve is connected with the torque limiter; the second end of the sleeve is used for being connected with an insulating operating rod of a ground rod; and the first end of the grip is connected with the torque limiter, and the second end of the grip forms an operating part. According to the ground rod torque limiting device provided by the invention, a maintainer can ensure that the torque meets the standard requirement in the process of installing a grounding wire, and the moderate stress at a grounding part is ensured, so that the disassembly is convenient, the potential safety hazard that the grounding wire falls is eliminated, and the grounding reliability is ensured.
Description
technical field [0001] The invention relates to the technical field of grounding rods, in particular to a torque limiting device for grounding rods. Background technique [0002] The grounding rod, that is, the rod-type grounding wire, consists of an insulated operating rod and a wire clamp. It is an important tool to ensure the staff when the voltage unexpectedly appears on the line that has been powered off. It is mostly used in the maintenance of power transmission lines. [0003] As the scale of power construction continues to expand, the tasks of operation and maintenance of transmission lines are becoming increasingly heavy. As one of the most important technical measures to ensure the safety of power outage maintenance operations, the installation of grounding wires requires strict control. Unreliable installation of grounding wires during power outage maintenance operations can easily lead to safety accidents, resulting in serious personnel and property losses. [0...
