| 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。

| Abstract: | 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 wi... |
