摘　　要：利用基于移动粒子半隐式方法的Particleworks,分析有载分接开关快速机构在油液环境中的切换特性.介绍有载分接开关快速机构的工作原理,设计有载分接开关快速机构的机械结构,给出快速机构在油液环境下的动力学计算基础.建立该有载分接开关快速机构在油液环境中的动力学仿真模型,对照了该快速机构在有无变压器油液环境中的切换特性差异,得到驱动电机的驱动扭矩要求大于40 N·m.分析油液黏度和储能弹簧刚度对该快速机构切换特性的影响,得到快速机构在油液环境下切换过程中飞轮受到的油液阻力矩的变化规律,通过流场分析揭示了飞轮受到的阻力矩变化和波动的原因.Switching characteristics of the quick mechanism for the on-load tap-changer in oil environment were analyzed by using Particleworks based on a moving particle semi-implicit method.The working principle of the quick mechanism of on-load tap-changer was introduced,the mechanical structure of a quick mechanism of on-load tap-changer was designed,and the basis for dynamic calculation of the quick mechanism in the oil environment was provided.A dynamic simulation model in the oil environment was established for the quick mechanism of the onload tap-changer,and switching characteristics were compared between the quick mechanism with and without transformer oil environment.The drive torque of the drive motor was required to be greater than 40 N·m.The influence of oil viscosity and energy storage spring stiffness on the switching characteristics of the fast mechanism was analyzed.The variation law of the oil resistance torque of the flywheel in the switching process of the fast mechanism under the oil environment was obtained,and the reasons for the variation and fluctuation of the resistance torque of the flywheel were revealed through the flow field analysis.
