500kv tension tower jumper repair pipe repair with two-split spacer

Abstract

The 500kV strain tower jumper repair pipe is repaired with two split spacers. In the process of operation, it often happens that the splint connecting the splint of the two-split jumper wire is disconnected from the wire, causing the wire to be worn or broken several strands. The composition of the present invention includes: the two-split spacer includes a detachably connected left limiting arm (1) and a right limiting arm (2), and the left clamping arm (3) is rotatably connected to the left limiting arm ), the right clamping arm (8) is rotatably connected to the right limiting arm, and the left limiting arm and the groove on the left clamping arm are docked to form a circular hole (4) structure, so The right limit support arm and the groove on the right clamping arm are docked to form a regular hexagonal hole (5)-shaped structure. The invention is used for the two-split spacer after repairing the jumper repair pipe of the 500kV tension tower.

Description

Technical field: [0001] The invention relates to a two-split spacer used for repairing a jumper repair pipe of a 500kV tension tower. Background technique: [0002] 500kV transmission lines mostly use 4-split and 6-split conductors, and the conductors are generally LGJ-400, LGJ-300 and LGJ-240. In order to ensure a reasonable gap between the jumper of the tension tower and the connecting fittings, avoid fatigue damage of the jumper clip, and avoid damage caused by the whipping of the wire and the fittings, the two-split jumper spacer bar is gradually widely used on the strain tower of the line. One end of the existing two-split jumper spacer is fixed at the outlet of the jumper, and the other end is fixed on the voltage equalizing shielding ring or the extension rod of the connecting plate, which acts as a support to prevent the jumper from colliding with and rubbing against the voltage equalizing shielding ring. According to the different directions of the jumper wires, th...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to solve the problem that the two-split jumper spacer is often disconnected from the connecting splint and the wire during the operation of the current two-split spacer, which causes the wire to be worn or broken. The repair pipe was worn off, leading to line tripping accidents, which improved the safety level of overhead lines and ensured the safe and reliable operation of 500kV tension tower jumper repair pipes with two split spacers.
