摘　　要：基于目前弹簧操动机构设计和改进中存在的问题,建立VS_1型高压断路器三维模型,对机构中的关键件滚轮外径进行参数化建模;利用ADAMS仿真技术,分析了滚轮尺寸变化对断路器特性的影响;通过仿真结果与仿真计算,说明了滚轮尺寸变化引起的机构力矩机械效益与机构运动特性的关系,并通过试验进行验证。试验结果表明:仿真分析得到的滚轮对断器特性影响趋势与试验结果一致,为机构特性设计提供了有效方法和重要依据。Based on the problems in design and improvement of spring operating mechanism, the 3D model of the VS1 high-voltage circuit breaker is built, and the parametric model of the key parts in the mechanism is established. The impact to the breaker characteristics with the dimension changing of the wheel is analyzed by the ADAMS simulation technology. The relationship between mechanical efficiency and institutional kinematic characteristicsis explained through the simulation results and the simulation calculation, and iris verified by the experiment. The research results can provide the basis for the design of the mechanism characteristics.
