摘　　要：基于现有分接开关的工作原理,分析了一种真空式有载分接开关的结构。在满足该分接开关整体电气拓扑时序要求、保证切换芯子按一定顺序动作的情况下,进行了分接开关储能弹簧刚度与时序的匹配设计。构建切换机构中单相隔离开关的ADAMS仿真模型,分析凸轮驱动单相隔离开关切换时系统最小输入量的导出方式,提出基于动量矩定理确定最小输入量的方法,并通过仿真验证了该方法的有效性。Based on the existing working principle of tap-changer,the structure of a vacuum on-load tap-changer is analyzed.The matching design of energy-storage spring stiffness and timing sequence is carried out under the requirement of meeting the overall electrical topology timing and ensuring the switching core acts in a certain sequence.The ADAMS simulation model of the single-phase isolating switch in the switching mechanism is constructed,and the derivation method of the minimum input quantity in the system in which the cam mechanism drives the single-phase isolating switch for switching is analyzed.Based on the moment of momentum theorem,a method to determine the minimum input which can meet the requirements is proposed.And the effectiveness of the method is verified by simulation.
