摘要
针对输电线路的疲劳特性,运用输电导线多功能试验系统对超高压输电线路中常用的LGJ400/35钢芯铝绞线进行了疲劳振动试验分析。结果表明,输电线路疲劳主要以应力疲劳和磨损疲劳为主,其中线夹出口处导线疲劳主要以应力疲劳为主,导线振动波腹处导线疲劳主要以摩擦疲劳为主。
Multi-function test system is used in LGJ400/35 ACSR EHV transmission lines for fatigue vibration test. The wire fatigue characteristics are analyzed based on experimental phenomenon and fatigue characteristics of transmission lines. The results show that the transmission lines fatigue primarily caused by stress fatigue and friction fatigue; the conductor fatigue at the exit of the clamp mainly caused by stress fatigue while the conductor fatigue at the vibration ampli rude mainly caused by friction fatigue.
