摘要
微风振动是造成架空线路导、地线疲劳断股的主要原因之一,严重威胁着大跨越导线的安全运行。根据IEC TC7、CIGRE/IEEE推荐的自阻尼测试方法以及IEEE给出的架空线振动测量的基础理论,结合大量的试验性研究,详细分析了大跨越导线的室内测振技术以及室外监测技术,提出了切实可行的室内消振试验方法以及适用于国内市场需求的现场监测仪器。
The aeolian vibration is the main reason which leads to fatigue damages of the overhead conductor and ground wire.It also affect the long span crossing running safely.This paper provides the feasible method for laboratory measurement of conductor weakening and the online measurement equipment which is suitable for the domestic market according to the method for laboratory measurement of conductor self-damping gived by IEC TC7 and CIGRE/IEEE,the basic theory for measurement of overhead lines vibration gived by IEEE and lots of testing research.
