Device for replacing wire spacers of +/-800kV power transmission line and application method

Abstract

The invention discloses a device for replacing wire spacers of a + / -800kV power transmission line and an application method. The device comprises an upper transverse shaft, a middle vertical shaft, alower transverse shaft, grab hooks, elastic pieces and a connecting rod structure, wherein the upper transverse shaft is connected with the lower transverse shaft through the middle vertical shaft, and the upper transverse shaft, the middle vertical shaft and the lower transverse shaft are lead screws; two end parts of the upper transverse shaft and the lower transverse shaft are connected throughthe connecting rod structure, the connecting rod structure comprises a first connecting rod and a second connecting rod, one end of the first connecting rod is hinged to the second connecting rod, the other end of the first connecting rod is hinged to the end part of the upper transverse shaft, one end of the second connecting rod is hinged to the first connecting rod, and the other end of the second connecting rod is hinged to the end part of the lower transverse shaft; and the two end parts of the upper transverse shaft, the two end parts of the lower transverse shaft and the hinged position of the first connecting rod and the second connecting rod are all provided with the grab hooks and the elastic pieces. The device solves the problem that two operators need to carry out spacer overhaul in a time-consuming and labor-consuming mode when the wire spacers of the + / -800kV power transmission line break down and need to carry out electric power overhaul.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance, in particular to a device and a use method for replacing conductor spacers of ±800kV transmission lines. Background technique [0002] Ultra-UHV transmission lines have the characteristics of large transmission capacity, large line span, and large tonnage of insulators. For ±800kV transmission lines, six-split conductors are generally used, and spacers are generally used to fix and control the spacing between the split conductors, so as to prevent the sub-conductors from whipping each other and suppress breeze vibration and sub-gap vibration. [0003] Generally, the spacer should have sufficient grip strength, and it is not allowed to loosen during long-term operation. The overall strength must withstand the centripetal force of the split wire when the line is short-circuited and the fatigue under long-term vibration. The spacer is in the coupling field of the electric fiel...
