光纤复合架空地线的防振

对目前国内OPGW的防振形式进行了归纳,提出对OPGW微风振动和舞动的治理方案。在OPGW微风振动的治理方面,对于一般线路而言,通常采用防振锤或防振鞭,而对于大跨越线路则宜采用阻尼线和防振锤组合防振的方式。为了保证实际工程中所采用的防振方案的有效性,对防振锤的选型,安装位置,安装方向,防振鞭的消振效果,阻尼线和防振锤组合防振的消振效果,进行了试验室模拟试验,并对试验数据进行了分析。文章也对OPGW舞动的形态、影响因素及防舞动措施进行了介绍,并提出了适用于OPGW的防舞动措施。

Vibration preventing of OPGW

This article concluded a variety of vibration preventing system for OPGW,which mainly included the treat with the breeze vibration and galloping for OPGW.Regarding the management on the breeze vibration of OPGW,vibration damper or spiral vibration rod is adopted for the common lines,combination of damping conductor and vibration damper are adopted for the large span lines.To ensure the validity of the damping systems in the practical projects,the laboratory measure about the selection of vibration damper,installing position and direction and the vibration-damping effects of the spiral vibration rod and the combination of the damping conductor and vibration damper were carried out,and the testing data were analyzed.This article also introduced the galloping types of OPGW,influential factors and galloping preventing measures,and the galloping preventing measures for OPGW were put forward.
