Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The embodiment of the present invention provides a method for installing, disassembling and replacing a linear wire supporter with electricity, including two processes of disassembling the old wire supporter and replacing and installing a new wire supporter: wherein, disassembling the old wire supporter includes the following steps :

[0036] 1-1) After two operators with insulating ropes go up the tower, with the cooperation of the ground personnel, they pass the tools to the tower;

[0037] 1-2) see figure 1 , install the pulley block 1, install the fixed end of the pulley block 1 on the crossarm on the upper par...

Abstract

The invention relates to the field of electrified installation of 66KV transmission lines, and particularly relates to a method for mounting, dismounting and changing a linear wire feeder in an electrification mode. The method comprises two processes of dismounting an old wire feeder and changing and mounting a new wire feeder, wherein the process of dismounting the old wire feeder comprises the following steps: transferring tools and instruments onto a tower by an operator with an insulating rope under the cooperation of personnel on the ground after climbing onto the tower; mounting a pulley block, and opening a U-shaped screw cap at first; taking off a U-shaped lead screw; taking off a pressing strip of a conducting wire; transferring conducting wire loads onto the pulley block by the pulley block to locate the wire feeder in a suspension state; and taking off a mandrel bolt of the wire feeder by using a mandrel bolt mounting device. The method provided by the invention is used for mounting, dismounting and changing the linear wire feeder without power cut, thereby expanding the operability range, increasing the electrified working projects and effectively improving the working efficiency.

Description

technical field [0001] The invention relates to the field of live installation of 66 kV transmission lines, and specifically relates to a method for live installation, disassembly and replacement of a straight wire supporter. Background technique [0002] The traditional 66 kV transmission line installation and dismantling of the linear wire supporter can only eliminate defects and replace the linear wire supporter when the power is cut off. Due to such defects, it is easy to cause the danger of live wires falling and the occurrence of major accidents, which seriously threatens the safe operation of the line. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for installing, dismounting and replacing a linear wire supporter with electricity, which avoids a series of complicated and cumbersome work processes such as planning, operation and various measures required for power failure. [0004] The present in...
