摘　　要：在自制导线微动磨损试验机上考察了钢芯铝绞线在干燥和酸性2种典型气候条件下的微动磨损行为,利用扫描电子显微镜和铁谱显微镜分析了试样导线内外层线股接触区的表面形貌和磨损微粒的形貌、尺寸等.结果表明:2种试验条件下靠近线夹处的导线磨损机理主要为黏着和疲劳剥落,中间导线段的磨损机理主要为黏着和磨粒磨损,酸性条件下导线内还存在明显的腐蚀磨损.On a self-manufactured overhead line Aeolian Vibration simulation tester,micro-vibration wear characteristics of aluminum cable steel reinforced（ACSR） under dry and acidic conditions were investigated.The surface topography of contact area between inner and outer layer stranded wire was analyzed by using scanning electronic microscopy.Morphology and size of wear particle were analyzed by ferrographic microscope.The results show that in both experiment conditions,wear mechanism of stranded wire near the cable clamp mainly included adhesive wear and fatigue wear,while near the middle section mainly there were adhesive wear and grain-abrasion.In acidic experiment conditions,the main wear mechanism was corrosive wear in stranded wire.
