Problems solved by technology

[0005] When the replacement wire is too long, the long-distance wire replacement anchor wire needs to be arranged on the cross arm or fittings of the tower body, and the anchor wire system and the anti-running wire system must be arranged with the same length. The length of the anchor wire system and the anti-running wire system is longer. The requirements for tools and appliances are relatively high. In order to improve safety, the layout workload of the anchor line system and anti-running system and tools and appliances is large, and the layout efficiency is low. In addition, the installation of the hanging points on the side of the rope tower is not properly arranged, and it is very easy to be split. Conductor crossing and friction affect construction and conductor quality, resulting in high safety risks

Embodiment Construction

[0029] The technical solution of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0030] Such as Figure 1-4 As shown, the method for replacing the damaged wire on the side of the strain tower over a long distance between multiple split wire stalls, the process includes the following steps:

[0031] S1: The front 3 spacers and wire anti-vibration hammers on the side need to be replaced when the outgoing line is removed. Tension clamp 2 is connected, and the jumper is temporarily fixed on other sub-conductors;

[0032] S2: New conductor 1 ground crimping strain clamp 2;

[0033] S3 At the two sides and the middle position of the replacement wire section, the new wire 1 is manually raised to the height of the original wire 4 of the part to be removed through the rubber pulley with the transfer rope, and the strain clamp 2 is connected to the adjustment plate 3, and the new and old wires are connected. System 6 co...

Abstract

The invention discloses a method for long-distance replacement of a damaged wire on a strain tower side among multiple split wire gears, and relates to the field of maintenance and repair of power transmission lines. When a damaged wire on the side of a strain tower is replaced in a long-distance mode between multiple split wire gears, an anchor wire system and a wire displacement prevention system which are equal in length need to be arranged, the arrangement workload is large, the efficiency is low, and due to improper arrangement of a rope tower body side hanging point, the rope tower body side hanging point and the multiple split wires are extremely prone to intersecting and rubbing, and construction and wire quality are affected. According to the method, the wires on the two sides of the wire breaking point are oppositely pulled, the anchor wire system and the wire displacement prevention system are arranged, the anchor wire system and the wire displacement prevention system can be arranged with few tools, a new wire is firstly hung, then an old wire is broken, and mutual backup protection is achieved. The arrangement workload of an anchor line system, a line displacement prevention system and tools is effectively reduced, the efficiency is improved, the use of the tools is reduced on the premise that the safety is ensured, the convenience and safety of replacement of damaged wires are effectively improved, secondary damage caused by friction between ropes and the wires is avoided, and the replacement quality is improved.

Description

technical field [0001] The invention relates to the field of maintenance and repair of power transmission lines, in particular to a method for long-distance replacement of damaged wires on the side of a tension tower between multi-split wire shelves. Background technique [0002] According to the "Code for Construction and Acceptance of 110kV~750kV Overhead Transmission Lines", when the wires of the transmission line are seriously damaged, all the damaged parts should be sawed off, and the wires should be reconnected with splicing pipes or pre-twisted wires with emery. [0003] Within a span, each wire should not exceed one connecting tube and two repairing tubes, the distance between the connecting tube and the outlet of the tension clamp should not be less than 15 meters, and the distance from the center of the suspension clamp should not be less than 5 meters. meters, and the distance from the center of the spacer bar should not be less than 0.5 meters. [0004] If the w...
