摘　　要：介绍了平行输电线路感应电流、感应电压的计算,并据此进行仿真计算,由于平行线路两端的接地开关在开断时会受潜供电流和恢复电压的影响,建议这些线路中应选用开合能力强的快速接地开关或超B类接地开关。This paper introduces the calculation of induced current and induced voltage of parallel transmission lines and the simulation computation is conducted.Considering the grounding switches of both sides of the parallel transmission line are affected by the secondary arc current and recovery voltage when switching on and off,the high speed grounding switch（HSGS） or B-point grounding switch is suggested to be selected.

关 键 词：平行线路 接地开关 感应电流 感应电压 潜供电流 恢复电压
