摘要
针对一起ZPW-2000A型移频轨道电路电压波动的典型案例,通过现场故障再现和电路分析,确认导致故障发生的根本原因是室内衰耗器端子间短路,造成电源混入,经采取相应措施,保证信号设备正常运用。
According to a typical case of ZPW-2000A frequency shift track circuit voltage fl uctuation,through the fi eld fault reconstruction and circuit analysis,it is confi rmed that the root cause of the fault is the short circuit between the terminals of indoor attenuator,resulting in the power supply mixing.The corresponding measures are taken to ensure the operation safety of signal equipment.
