单路供电对ZPW-2000A轨道电路接收器影响分析

Analysis and Treatment of ZPW-2000A Track Circuit Receiver Failure in Single Power Supply

客专ZPW-2000A移频轨道电路,在电源屏输出采用双断空开设计的车站运用时,移频柜在单路电源供电状态下,接收器会发生故障报警。通过对单双路电源供电时,轨道电路设备内部工作原理分析,找出故障原因,并提出可行的解决方案,以保证设备的正常工作运行。

When DPL ZPW-2000A frequency-shift track circuit applies in station adopting double-break open design for power supply screen output,and the frequency-shift cabinet is under the condition of single power supply,the receiver will give fault alarm.In case of the power supply of single and dual power supply,the internal working principle of track circuit equipment is analyzed to fi nd out the cause of fault and a feasible solution is proposed to ensure the normal operation of equipment.
