摘　　要：目前,高铁线路将轨道电路调谐区小轨道纳入列控控制,调谐区小轨道的状态也成为行车的重要依据。在应用过程中发现,小轨出信号存在受干扰情况,进而引发小轨出电压波动较大的现象。针对该现象,通过原理分析、实验室测试和现场验证等方式对小轨道电压波动原因进行分析,提出ZPW-2000A轨道电路小轨道抗干扰能力优化方案,改善了小轨道受干扰产生电压波动的问题。At present,the short track circuits in the tuning zones of the track circuits have been included in the train control systems of high-speed railway lines,and the cleared and occupied status of the short track circuits in the tuning zones has also become an important basis for train operation.During the application process,it is found that the output signals of the short track circuits are interfered,leading to unstable output voltage of the short track circuits.To address this phenomenon,this paper analyzes the causes of voltage fluctuations in the short track circuits through principle analysis,laboratory tests andfield verification.The scheme to optimize the anti-interference ability of the short track circuits of ZPW-2000A track circuits is proposed,and the problem of voltagefluctuations caused by disturbances in short track circuits is mitigated.
