Overhead ground wire replacement method

Abstract

The invention discloses a method for replacing an overhead ground wire. The method for replacing an overhead ground wire comprises the following steps: determining a construction site, where a plurality of transmission towers are arranged at intervals in sequence; They are the first transmission tower and the second transmission tower, respectively. The wire tension equipment is arranged under the first transmission tower, and the wire pulling equipment is arranged under the second transmission tower; Put it into the pay-off pulley; connect the new ground wire between one end of the old ground wire and the wire tensioning device, and connect the guide wire between the other end of the old ground wire and the wire pulling device; use the wire pulling device to pull the guiding wire To pull the new ground wire to the position of the old ground wire; connect and tighten the new ground wire; remove the pay-off pulley. The overhead ground wire replacement method of the present invention avoids the situation in the related art that the overhead ground wire needs to be replaced after a power failure, and reduces the impact on economic production.

Description

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

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.
