Abstract

This application relates to the technical field of installation of overhead power transmission lines, in particular to a method for installing a ground wire lifter and ground wire accessories, including a cross bar, a tripod, a wire hook and a chain hoist; The first end of the cross bar, the chain hoist is arranged at the second end of the cross bar, and the tripod is rotatably installed in the middle of the cross bar; the tripod includes the first connecting rod, the second A connecting rod and a third connecting rod, the second connecting rod is located on the side of the tripod away from the cross bar; the first connecting rod and the third connecting rod are respectively equipped with a first angle steel grabber and the second angle steel grabber; both sides of the second connecting rod are provided with cross-arm connection holes connected with the ground wire connection holes of the cross-arm. This application does not need the process of tightening the chain hoist multiple times to receive force and loosen the force, and only one chain block is needed in the whole process, which effectively solves the technical problem of inconvenient installation of ground wire accessories in the prior art.

Description

technical field [0001] The present application relates to the technical field of installation of overhead transmission lines, in particular to a method for installing a ground wire lifter and ground wire accessories. Background technique [0002] The ground wire, also known as the lightning protection wire, is erected on the top of the overhead line and refers to the wire directly connected to the earth on the high-voltage and ultra-high-voltage lines. Due to the shielding of the ground wire to the wire and the coupling between the wire and the ground wire, the chance of lightning directly hitting the wire can be reduced. When lightning strikes the tower, part of the lightning current can be shunted through the ground wire, thereby reducing the potential of the tower top and improving the lightning resistance level. [0003] In the construction of overhead lines, when the ground wire is laid out, the ground wire under the cross arm is on the wire pulley, and it is necessary...
