摘　　要：以电机直驱高压真空断路器系统为模型,分别从运动学和动力学角度,推导了高压真空断路器的几何约束、运动特性,得到电机转子旋转运动与灭弧室动端竖直运动行程的映射关系。同时,对高压真空断路器各主要运动部件进行了受力分析,并建立起电机直驱操动机构的负载模型。仿真和试验结果表明,所提电机直驱操动机构负载分析方法在最大转矩需求计算方面,能够为驱动电机及变换器容量设计提供理论指导,对于电机直驱操动机构行程曲线规划具有指导意义。The high-voltage vacuum circuit breaker system of motor direct drive is used as a model,and the geometric constraints and motion characteristics of the high-voltage vacuum circuit breaker are derived from the kinematic and dynamic perspectives respectively,and the mapping relationship between the rotational motion of the motor rotor and the vertical motion stroke of the moving end of the arc extinguishing chamber is obtained.At the same time,the force analysis of the main moving parts of the high-voltage vacuum circuit breaker is carried out,and the load model of the motor direct drive operating mechanism is established.Simulation and experimental results show that the load analysis method of motor direct drive actuator proposed can provide theoretical guidance for the design of drive motor and converter capacity in terms of maximum torque demand calculation,and has guiding significance for the stroke curve planning of motor direct drive actuator.
