摘　　要：随着社会用电需求越来越高,为保障10kV架空线路不发生相间碰线短路跳闸,使线路安全可靠运行,通过搭建导线覆冰模型,模拟覆冰导线在静力和动力作用下的运动状态,采用有限元方法模拟分析三角形排布中压架空线路的覆冰舞动特性,分析导线线径与材质对线路舞动和受力的影响。综合考虑间隔棒的防舞效果、成本以及安全可靠性,提出了相间间隔棒的防舞方案,实验证明显著的降低架空线路舞动幅度,提高架空线路的安全可靠性。With the increasing demand for electricity in the society, in order to prevent the short-circuit trip of 10kV overhead lines from interphase wire collision and ensure the safe and reliable operation of the lines, the ice covering model of the wires was built to simulate the motion state of the ice-covered wires under static and dynamic action, and the dynamic characteristics of the ice dancing of the overhead lines in the triangular arrangement were simulated by finite element method. The influence of wire diameter and material on line movement and force is analyzed. Considering the anti-dance effect, cost and safety reliability of spacer bar, the anti-dance scheme of interphase spacer bar is proposed. The experiment proves that the dancing amplitude of overhead line is sig-nificantly reduced and the safety and reliability of overhead line is improved.
