Abstract

The invention relates to a wire lifting tool for an intermediate phase conductor of a 10kV same-pole multi-circuit line. The wire lifting tool comprises a stand column, two support rods and an electric rod hoop, wherein the support rods and the electric rod hoop are respectively fixed at two ends of the stand column, the two support rods are arranged on two sides of the stand column and on the same plane with the stand column, two wire fasteners are respectively suspended at the end portions of the two support rods, and a conductor metal hook is connected under the wire fastener; and a cross arm clamp is installed in the middle of the stand column. The wire lifting tool has the advantages that electrified lifting of the intermediate phase conductor of the 10kV same-pole multi-circuit line can be achieved, and safe distance between operation staff and an electric transmission line can be ensured. The wire lifting tool is simple in structure, convenient to transport, assemble at site and carry, and flexible to install and adjust on a rod, has good at-site practical performance, facilitates development of electrified operation of the 10kV power distribution line and improves operation reliability of the electric transmission line.

Description

Technical field [0001] The invention belongs to the technical field of overhaul and maintenance of power distribution lines, and relates to a wire-lifting tool used for overhauling phase conductors during live operation of a 10kV multi-circuit transmission line on the same tower. Background technique [0002] The wire lifting tool for live working is one of the common tools for live maintenance of power transmission and distribution lines. It is mainly used to lift wires during live working, transfer the mechanical load on the insulator string, and withstand electrical insulation of the corresponding voltage level. At present, the tools used to lift the line in the live operation of the 10kV line, such as the claw pole, are mainly used to lift the side-phase conductor of the 10kV line. For the intermediate phase conductors close to the tower in the 10kV three-circuit or above line on the same pole, due to the small distance from other surrounding circuits and the tower, the exist...
