摘　　要：介绍了RADSS/S型高速比率制动母线差动保护装置的原理与特点,针对该保护在母联兼旁路开关转代线路开关的同时,又有其他线路或发电机、变压器开关倒闸操作的特殊运行方式下存在的问题,提出了改造方案。The working principle and features of Type RADSS/S highspeed ratiorestrained busbar protection are introduced. If the bus tie and bypass circuit breaker is in place of a line circuit breaker, and another line, generator, or transformer circuit breaker is in a special condition of changeover operation, this protection may have problems. To cope with this situation, a modification scheme is proposed.
