摘　　要：紧凑型电力线相间舞动一直是危及线路安全运行的因素之一,舞动和跳跃力的重叠通过率低,导致路线暂停的概率很高,尤其是500kV紧凑线路,一旦发生舞动安全事故,将对系统造成极大危害,严重干扰供电系统的稳定性。在这个阶段,安装相间垫片是紧凑路线最直接和最有效的防舞措施。然而,目前的相间垫片使用铰链球窝连接,此类连接件为非标产品,连接件长度小,安装调整量小,难度较大,很容易使交替排列的位置受到集中的地面应力,导致交替排列的破裂。针对500kV紧凑型线路相间间隔棒球头断裂,在对间隔杆连接方法的科学研究的基础上,研制了间隔杆辅助设施4点连接分导体间隔杆,并在多条500kV紧凑线路上进行了试运行,实际效果极佳。Interphase dancing of compact power lines has always been one of the factors endangering the safe operation of the line.The overlapping passing rate of dancing and jumping forces is low,leading to a high probability of suspension of the line,especially for 500kV compact lines.Once a dancing safety accident occurs,it will cause great harm to the system and seriously interfere with the stability of the power supply system.At this stage,the installation of interphase gaskets is the most direct and effective anti-dance measure for tight routes.However,the current phase gasket uses hinged ball and socket connection,this kind of connector is non-standard product,the length of the connector is small,the installation adjustment amount is small,it is difficult,it is easy to make the position of the alternate arrangement by concentrated ground stress,resulting in the rupture of the alternate arrangement.Aiming at the break of interphase spacer head of 500kV compact line,on the basis of scientific research on the connection method of spacer bar,the auxiliary facilities of spacer bar with 4-point connection of divider conductor spacer bar are developed and tested on several 500kV compact lines with excellent practical results.
