摘　　要：新型电力机车主断路器用电磁操动机构处于合闸位置时,其保持力由一组保持线圈励磁实现。由于机车上电源电压波动大且机车工作环境温度变化大,此保持力的变化范围非常大。为了稳定合闸时的保持力,保证电磁操动机构稳定工作,提出采用直流斩波的方法对合闸保持力进行补偿。When the new type electromagnetic operating mechanism using for electric locomotive main circuit breaker is in the closing position, its keeping force is provided by a group of holding coil. Because of power supply voltage on the locomotive and environment temperature of the locomotive all changes greatly.In order to stabilize the keeping force, guarantee the stability of electromagnetic operating mechanism, a dc chopper method is proposed to compensate keeping force.
