摘　　要：针对广州地铁13号线ZDJ9转辙机频繁发生自动开闭器动接点卡滞的问题,横向对比测试了ZDJ9、ZD6、ZYJ7转辙机动接点所受拉力与阻力,并对动接点进行了受力分析。基于研究得出的动接点受力关系及阻力范围,提出了包括增加自动开闭器弹簧额定拉力或者辅助弹簧的优化解决方案。经实践,该方案可有效降低动接点卡滞几率,具有参考和推广意义。In view of the frequent sticking of the movable contact of the switch circuit controller of ZDJ9 switch machine in Guangzhou Metro Line 13,the tension and resistance of the movable contact of ZDJ9,ZD6 and ZYJ7 switch machines are tested horizontally,and the force on the movable contact is analyzed.Based on the force relationship and resistance range of the movable contact obtained from the research,an optimization solution including either increasing the rated tension of the automatic switch circuit controller spring or auxiliary spring is proposed.Through practice,it can effectively reduce the probability of movable contact stagnation,and has reference and promotion significance.
