Overhead ground wire replacement method

Abstract

The invention discloses an overhead ground wire replacement method, and the method comprises the following steps: determining a construction site which is internally provided with a plurality of powertransmission towers which are sequentially arranged at intervals; wherein the power transmission towers located at the two ends of the multiple power transmission towers are the first power transmission tower and the second power transmission tower respectively, wire tension equipment is arranged below the first power transmission tower, and wire traction equipment is arranged below the second power transmission tower; mounting a paying-off tackle on each power transmission tower, and putting the old ground wire into the paying-off tackle; connecting a new ground wire between one end of the old ground wire and the wire tension device, and connecting a guide wire between the other end of the old ground wire and the wire traction device; pulling the guide wire by using wire pulling equipment so as to pull and spread the new ground wire to the old ground wire position; connecting and tightening a new ground wire; and dismantling the paying-off tackle. According to the overhead ground wire replacement method, the situation that the overhead ground wire can be replaced only after power failure in the prior art is avoided, and the influence on economic production is reduced.

Description

technical field [0001] The invention relates to the technical field of overhead line construction, in particular to a method for replacing an overhead ground wire. Background technique [0002] In related technologies, the existing overhead lines are faced with the requirements of line replacement, maintenance, and upgrading with the increase of running time and the needs of local power grid construction. At present, the post-maintenance and replacement of overhead lines requires electric power personnel to climb to the transmission tower to carry out operations. For the sake of safe operation, electric power personnel need to cut off the power when working on the transmission tower. On the one hand, the power outage construction needs to first report the power outage to the management department According to the plan, the power outage notice will be issued after the management department evaluates it. The whole process is redundant and time-consuming, which is not conducive...

At present, the post-maintenance and replacement of overhead lines requires electric power personnel to climb to the transmission tower to carry out operations. For the sake of safe operation, electric power personnel need to cut off the power when working on the transmission tower. On the one hand, the power outage construction needs to first report the power outage to the management department According to the plan, the power outage notice will be issued after the management department evaluates it. The whole process is redundant and time-consuming, which is not conducive to rapid construction. On the other hand, it will cause residents to lose power and cause losses to economic production.
