降低架空输电线路防振锤滑移率的研究

Research on Shifting Rate Reduction of Stockbridge Damper of Overhead Transmission Lines

在架空输电线路的导、地线上安装防振锤,是防止架空输电线路导、地线因为振动而出现断线、断股事故的主要措施之一。但由于各种原因的作用,防振锤在安装一段时间后滑移出原有的安装位置,失去防振作用,威胁导、地线安全运行。分析了防振锤出现滑移的各种原因,并对现使用的防振锤结构提出改进措施,取得了较好的效果。

The stockbridge damper, as a major way of preventing line break or strand break due to vibration, is installed on conductors and grounding wires of overhead transmission line. However, the stockbridge damper shifts after some time from the original place due to various reasons and fails to control the vibration, which poses threats on operation safety of conductors and ground wires. The paper analyzes various reasons of stockbridge damper shifting and proposes measures for improving the structure of existing stockbridge damper. Therefore, favorable effect is achieved.
