Reducing inrush current to capacitor banks

The present disclosure relates to a method for reducing inrush current to an ungrounded capacitor bank (2) when a switching device (1) is reclosed. The method comprises disconnecting the switching device, the disconnecting switching device comprising interrupting the current of a first phase (R) of the three phases and simultaneously interrupting the current of a second phase (S) and a third phase (T) of the three phases after a predetermined disconnecting time period. The method further includes re-closing the switching device, the re-closing switching device including simultaneously turning on respective currents of the second phase and the third phase, and turning on the current of the first phase after a predetermined closing period of time. 本公开涉及一种用于减少在重新闭合开关设备(1)时去往未接地的电容器组(2)的涌入电流的方法。该方法包括断开开关设备，断开开关设备包括中断三相中的第一相(R)的电流，并且在预定断开时间段之后，同时中断三相中的第二相(S)和第三相(T)的电流。该方法还包括重新闭合开关设备，重新闭合开关设备包括同时接通第二相和第三相的相应电流，并且在预定闭合时间段之后，接通第一相的电流。
