摘　　要：通过断口宏观观察、化学成分分析、金相组织分析及力学性能试验,对某330KV变电站铝设备线夹断裂事故进行分析。结果表明,断裂线夹存在质量问题,强度不足,加之服役过程中线夹自身的电动力效应,是线夹发生断裂的主要原因。The fracture fault of aluminum device clamp in 330 KV substation was analyzed by morphology of fracture surface, chemical composition, microstructure and mechanical properties analysis, The results show that the insufficient strength and the electrodynamic effect of the device clamp causes the device clamp fractured during the service.
