一种±1100kV直流滤波器带电投切系统和方法
摘要：
本发明提供一种±1100kV直流滤波器带电投切系统和方法，带电投切系统包括直流极线、中性母线、第一隔离开关、第二隔离开关和直流滤波器；所述直流滤波器一端通过第一隔离开关和直流极线连接，另一端通过第二隔离开关与中性母线连接。本发明可有效降低±1100kV直流滤波器合闸涌流30％～70％，可带电投切±1100kV直流滤波器，检修时不中断功率输送。可有效带电投切直流滤波器，减小涌流，且设备电压等级较低，有利于节省投资。
摘要（英）：

The invention provides an electrified switching system and an electrified switching method of a +/-1100kV direct-current filter. The electrified switching system comprises a direct-current polar line, a neutral bus, a first partitioning switch, a second partitioning switch and a direct-current filter, wherein one end of the direct-current filter is connected with the direct-current polar line through the first partitioning switch; the other end of the direct-current filter is connected with the neutral bus through the second partitioning switch. By adopting the electrified switching system and the electrified switching method, the switch-in rush current of the +/-1100kV direct-current filter can be reduced by 30-70%, the +/-1100kV direct-current filter can be switched in an electrified manner, and power conduction is not interrupted in overhaul. Direct-current filters can be effectively switched in the electrified manner, the rush current is reduced, the voltage grade of equipment is relatively low, and the investment can be reduced.
