ADSS微风振动问题的探讨

Discussion on aeolian-vibration for ADSS

全介质自承式光缆(ADSS)由于其低阻尼特性更易发生微风振动,易造成ADSS的疲劳断缆或光纤损伤,危及电力通信线路的安全运行。国内首次对ADSS的自阻尼特性进行了测试,并对使用的两种防振金具的防振方案进行设计,并采用能量平衡原理分别对防振效果进行了评估和比较。

All Dielectric Self-Supporting(ADSS)fiber optical cables take place aeolian-vibration due to their low self-damping characteristics.It may results in breakage of cables or damage of fibers,and endangers the safe run of the power communication transmission lines.The self-damping characteristics of ADSS is tested firstly in China, and damping systems are designed by using two kinds of vibration damper.By using the energy balance theory,the effectiveness of the two kinds of damping systems are evaluated and compared in the laboratory.
