残压计算为自动二次重合闸装置的设计人员提供了理论依据，也是分析异步电动机电容制动过程的基础。

The computation of residual voltage offers the theoretical foundation to the design of automatic secondary reclose, and it is also the analysis basis for capacity braking.

高压、超高压输电线路的开关为分相开关，当对侧开关单相偷跳后，在线路负荷比较重、同时重合闸动作时间比较长的情况下可能引发系统振荡。

HV and EHV transmission lines are equipped with split-phase breaker. If a longer reclosing time is setting in a heavy load line, the system may swing after the trip without fault of remote breaker.

为利于故障点灭弧，提高单相重合闸的成功率，一般采用并联电抗器加中性点电抗器的接线方式。

The connection of shunt reactor and neutral reactor is normally used to extinguish arc and to ensure success of autoreclosure.
