摘要

某220kV输电线路沿南北方向布置，采用预制螺旋阻尼器防止导线风振。在2016年初的输电线路隐患检查中，发现阻尼器预成型螺旋钳磨损了大量导线，严重影响了输电线路的安全稳定运行。本文从防振机理、阻尼器结构、沿线气象条件和防振措施等方面分析了导线失效的原因。并提出了相应的改进措施和建议。

Failure Analysis of Overhead Conductors Damaged by Preformed Helical Stockbridge Damper

A certain 220kV transmission line is arranged in the north-south direction, and the preformed helical dampers are adopted to prevent aeolian vibration of conductors. During the inspection of hidden defects of the transmission line at the beginning of 2016, it was found that a large number of conductors were worn by preformed helical clamps of the dampers, which seriously affected the safe and stable operation of the transmission line. In this paper, the failure causes of conductor wire are analyzed from several aspects including anti-vibration mechanism, damper structure, meteorological conditions along the line and anti-vibration measures. In addition, corresponding improvement measures and suggestions are put forward.
