Problems solved by technology

[0008] The present invention is to solve the problem that the cross-sectional area of ​​continuous damage or the loss of strength does not exceed the provisions of Article 7.2.3 of this code to repair the repairing pipe, but the damaged length exceeds the repairable range of the repairing pipe. Cut off all of them and reconnect them with connecting pipes, resulting in the problems of cumbersome maintenance operations, long working hours, high labor intensity, high operating risks and high economic costs, and a repairing method for repairing pipes of overhead line conductors is provided

specific Embodiment approach 1

[0018] Specific implementation mode one: the repairing pipe repairing of the overhead line conductor of this embodiment is carried out as follows:

[0019] 1. Measure the length of missing strands or supplementary strands of overhead line conductors, and intercept supplementary strands with the same twist direction, equal length, and the same model;

[0020] 2. Wrap the supplementary strands prepared in step 1 on the wires that are missing or need to be supplemented, and temporarily wind and fix the two ends of the supplementary strands with binding wires;

[0021] 3. Clean the two ends of the replenishment with an iron brush and apply conductive paste with the end of the replenishment as the center;

[0022] 4. Install the drawer-type repairing tube of the same type as the overhead line wire to one end of the repairing wire, and use the hydraulic press to alternately crimp the two sides of the repairing pipe with the end of the repairing wire as the center; the other end of t...

specific Embodiment approach 2

[0024] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the supplementary strands described in step 1 are aluminum wires. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0025] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is: in step 3, use an iron brush to clean the two ends of the repair and apply the conductive paste to the same length as the repair pipe. Other steps and parameters are the same as those in Embodiment 1 or 2.

Abstract

The invention discloses a method for repairing a repair sleeve of an overhead line conductor, relating to a method for repairing a repair sleeve of a conductor and aiming at solving the problems of fussy maintaining operations, long operating time, great labor intensity, high operational risk and high economic cost caused by that the conductor which has continuously damaged cross section or loss intensity within the provision of repairing by the repair sleeve mentioned in Article 7.2.3 of the specification and has the damage length beyond the repair range which the repair sleeve can reach, must be cut off completely and connected again by a splicing sleeve. The repairing method comprises the steps of: 1, selecting a repairing strand; 2, temporarily winding and fixing the repairing strand; 3, cleaning and coating a conductive paste; 4, crimping; and 5, detaching a binding line and filing off edges and corners as well as burrs on the crimped repair sleeve by a flat file. The method for repairing the repair sleeve of the overhead line conductor, disclosed by the invention, can be used for repairing the overhead line conductor.

Description

technical field [0001] The invention relates to a repairing method for a repairing pipe of a wire. Background technique [0002] 7.2.4 of "Code for Construction and Acceptance of 110-500kV Overhead Lines" stipulates that when one of the following situations occurs when the conductor is damaged at the same place, all damaged parts must be cut off and reconnected with a splicing tube: [0003] 1. When the strength of the wire loss or the cross-sectional area of ​​the damage exceeds the provisions of Article 7.2.3 of this code to repair with repair pipes; [0004] 2. The cross-sectional area of ​​continuous damage or the loss of strength does not exceed the provisions of Article 7.2.3 of this code to repair the repair pipe, but the damage length has exceeded the repairable range of the repair pipe; [0005] 3. The wire steel core of the composite material has broken strands; [0006] 4. Gold hooks and broken strands have caused permanent deformation of the steel core or inner...
