电力机车自动过分相功能检测系统是保证电力机车自动过分相的功能正常可靠,保证电力机车安全自动通过分相点的有效手段。电力机车自动过分相功能检测系统包括3个部分的检测:(1)检测车载的自动过分相装置是否正常可靠。(2)检测电力机车运行区段内各分相点的4个地面信号是否未丢 The automatic over-phase function detection system of electric locomotive is an effective means to ensure the automatic over-phase function of electric locomotive and ensure the safety of electric locomotive automatically through the phase separation point. Electric locomotive automatic over-phase function detection system includes three parts of the test: (1) to detect vehicle-mounted automatic over-phase device is normal and reliable. (2) Check whether the 4 ground signals of each phase point in the running section of electric locomotive are not lost
