摘　　要：介绍了城市轨道交通牵引供电直流保护测控装置的软硬件设计及研发难点。该装置目前已通过相关部门的型式试验和电磁干扰4级严酷测试,能够严格区分机车工作电流和故障电流,不受噪声和干扰的影响,快速准确地切除故障。The software and hardware development of the protective and monitoring device for the direct current system is introduced in detail. This device is characterized with the ability of distinguishing the working current of the locomotive and the fault current, and can exclude the noise and other interferences, and thus can trip accurately against faults.
