摘　　要：紧凑型线路导线覆冰脱落往往会引发相间及相地闪络跳闸、导地线断股、断线等,为反演故障过程,指导紧凑型线路防冰加固设计及改造,以某500 kV紧凑型线路脱冰跳跃相间闪络跳闸故障为研究案例,基于ANSYS软件建立覆冰导线-绝缘子-相间间隔棒体系的有限元模型,模拟4种脱冰工况,分析不同工况下导线脱冰振动响应,得到导线在脱冰过程中相间间隙和相间间隔棒轴力的变化规律。To reverse the fault process and guide the antiicing reinforcement design and reconstruction of compact lines,a finite element model of iced conductor-insulator-interphase spacer system is established based on ANSYS software to simulate four deicing conditions.The vibration response of conductor deicing under different working conditions is analyzed,and the variation rules of inter-phase clearance and inter-phase spacer axial force in the process of conductor deicing are obtained.
