Controllable anti-detachment type high-voltage power line grounding wire device

Abstract

The invention provides a controllable anti-detachment type high-voltage power line grounding wire device, which relates to the technical field of high-voltage inspection and repair equipment. The grounding wire device comprises an angle steel fixing seat, a clamping device, a grounding wire and an insulating rope. The clamping device comprises a hook, a left clamping kit and a right clamping kit are mounted on the hook; The left clamping kit and the right clamping kit are of the same construction, A left and a right are oppose and symmetrically arranged on that hook, the inner jaws on the leftand right clamping kits can be opened and closed relatively synchronously, When the two inner jaws are folded together with the lower jaw seat or the hook, the outer jaw limits the rotational freedomin one direction through the limit block of the outer jaw, and can only rotate in one direction, thus realizing the anti-falling function of preventing the outer jaw from falling out. When the deviceof the invention clamps wires, the clamping is firm and reliable, the device has the function of preventing wires from falling off, can be adapted to clamp wires with different wire diameters, and the wires are dismantled and hung accurately and conveniently, thereby improving the convenience of high-altitude operation.

Description

【Technical field】 [0001] The invention relates to the technical field of ultra-high voltage maintenance equipment, in particular to a controllable anti-off type high-voltage power line grounding wire device. 【Background technique】 [0002] It is a technical measure to ensure safety when carrying out power outage inspection and maintenance work on transmission lines. At present, most of the short-circuit grounding wire clamps used in domestic AC and DC lines with a voltage level above 10kV are impact type and tongue-type compression type clamps. Due to the inherent structural and principle defects of the clamps, there may be contact between the clamps and the wires. It is a safety hazard that is not firm, easy to fall off by impact or pulling. In addition, according to the "Notice of China Southern Power Grid Corporation on the Implementation of Supplementary Regulations on the Practice and Management of Grounding Wires and Personal Security Wires", the grounding wire or per...
