摘　　要：在自制导线微风振动模拟试验机上,于8%拉断张力下,对LGJ150/25型钢芯铝绞线完成了3种不同振动周次下的微风振动磨损试验。在线夹出口89mm处采集了磨损微粒,利用铁谱仪、扫描电镜和能谱仪对磨粒表面微观形貌、成分和尺寸进行了分析。结果表明,钢芯铝绞线铝线股的磨损主要为磨料磨损和氧化腐蚀磨损;随着振动周次的增加,磨粒尺寸迅速减小,几何长短轴比逐渐趋于1,棱角逐渐变得平滑,形成粒度较小,数量较多,且分布均匀的磨损微粒;在1×107振动周次下,试验导线的钢芯线发生较为明显的磨损现象。The aeolian vibration wear of LGJ150/25 type aluminum conductor steel reinforced （ACSR） was explored through self-manufactured conductor line aeolian vibration simulation tester in three different vibration times under 8% ultimate tensile strength （UTS）. The wear debris at 89 mm export clamp was collected and the surface micro-morphology, composition, and size of wear debris were analyzed by using ferrograph, scanning electron microscope （SEM） and energy spectrometer. The results show that the wear of aluminum wire strand in ACSR is mainly abrasive wear and oxidation corro- sion wear. With the increase of vibration times, the size of wear debris decreases rapidly, the ratio of geometry major and minor axis gradually tends to one and the edges and corners gradually become smooth, and then smaller particle size, larger in number and well distributed wear debris is formed. In 1×10^7 vibration times, steel wire in the test conductor occurs more obvious phenomena of wear.
