摘　　要：分合闸速度及合闸弹跳时间等是反映真空断路器电气性能的关键参数,若不符合要求,将导致触头磨损严重、触头烧蚀、降低灭弧室使用寿命。介绍磁控真空断路器的结构及工作原理,通过一系列理论计算详细分析影响其机械特性的因素,并采用因素分析法进行相关试验测试,最终得出机械特性参数随分闸簧力、触头压力、磁保持力的变化趋势,为实际生产过程中设计、安装磁控真空断路器提供参考依据。Opening and closing speed and closing bounce time are the key parameters that affect the electrical performance of vacuum circuit breaker.If they do not meet the requirements,the contact will be seriously worn or even ablated,and the service life of the interrupter will be shortened.The structure and working principle of magnetically controlled vacuum circuit breaker are introduced,and the several factors affecting its mechanical characteristics are analyzed in detail through a series of theoretical calculations.The related tests are carried out by the factor analysis method.Finally,the changing trend of mechanical characteristics parameters with the spring force,contact pressure and magnetic retention force is obtained,which provides a reference for designing and installing the magnetically controlled vacuum circuit breaker in actual production process.
