摘　　要：快速接地开关作为高压开关电器设备的重要模块,通常采用弹簧操动机构作为其驱动装置,降低机构驱动弹簧操作功,能够有效地减小传动系统所受的冲击载荷,对提高快速接地开关稳定性和可靠性具有重要意义。笔者通过建立快速接地开关三维模型,开展动力学仿真计算,对仿真数据进行分析,发现了驱动弹簧关键参数与快速接地开关合闸速度之间的对应关系,提出了一种驱动弹簧的优化设计方法,并通过样机试验验证了该方法的可行性。试验结果表明,该方法设计的驱动弹簧,既能满足合闸速度要求,又可实现驱动弹簧操作功最小化。As an important part of high voltage switchgear,fast earthing switches（FES）usually uses spring operatingmechanism,decreasing the operating power of mechanism driven spring,can effectively reduce the impact load ofthe transmission system,and is significant to improve the reliability and stability of FES. In this article,the model ofFES is built,dynamic simulation calculation is carried out,the data of simulation is analyzed,the relationship isfound between FES closing speed and key parameters of operation spring,an optimal design method for drivingspring is proposed,and the effectiveness of the design method is proved by test on a spring. The test results show thatthe driving spring designed by this method can not only meet the requirements of closing speed,but also realize theminimization of the operating power of the driving spring.
