摘　　要：分合闸速度是影响真空断路器性能的关键参数,为了得到合适的分合闸速度,文章详细分析了真空断路器的分合闸动作原理,阐述了合闸速度和分闸速度的计算过程,得出了分合闸速度的变化规律。以活塞推杆质量为例,研究运动机构参数对分合闸速度的影响,建立这些参数与分合闸速度之间的关系,即可通过改变这些参数值得到合适的分合闸速度。The opening and closing speed is the key parameter affecting the performance of vacuum circuit breaker.In order to obtain the appropriate opening and closing speed,this paper analyzes the opening and closing operation principle of vacuum circuit breaker in detail.It expounds the calculation process of closing speed and opening speed,and obtains the change rule of opening and closing speed.Taking the mass of piston push rod as an example,the influence of motion mechanism parameters on the opening and closing speed is studied,and the relationship between these parameters and the opening and closing speed is established.The appropriate opening and closing speed can be obtained by changing these parameters.
