摘　　要：并联电容器作为一种主要的无功补偿设备,广泛应用于各电压等级的变电站中,投切开关是影响并联电容器可用率和无功补偿实际效果的主要元件。以电容器投切开关为对象,结合运行实际,分析存在问题。阐述了10 kV电容器智能投切装备的投切机理,介绍了研制的一种智能投切装置的结构、控制系统、控制方式。通过系统仿真与变电站实际工程应用,验证了其可行性与市场价值。As one of the main reactive power compensation methods, applications of the parallel compensation capacitor system are extensively observed in substations of different voltage grades. Capacitor switch of the system is the main component which affects the capacitor usability and reactive compensation performance. The operation status and existing problems in engineering of the capacitor switch are presented. Based on both above and the switch principle analysis, this paper proposed a new intelligent switch device which has the functions of transient impulse suppression and smooth switch. Series of system simulation results and an engineering application case are both presented to validate the feasibility of the proposed system and the marketing value of the device.
