基于区间相邻轨电压波动原因分析及对策

为彻底消除电气化铁路自动闭塞轨道电路对区间相邻线路及相邻线路区段窜频信息的干扰,经过组织专业技术人员对容易造成ZPW-2000A轨道电路产生窜频干扰的所有原因进行分析,重点从供电专业吸上线设置、电务专业横向连接线设置以及轨道电路电气参数进行分析,梳理、总结,考虑现场各种可能造成窜频信息干扰要素,如数字电缆施工工艺不良、调谐单元电气特性不良等,提出解决方案并实施,彻底消除了区间轨道电路安全隐患。

Analysis of Causes of Voltage Fluctuation of Adjacent Tracks in Sections and Solutions

In order to eliminate frequency interference to adjacent line segments caused by track circuits in automatic block sections of electric railways, a group of professionals have analyzed and summarized all the factors leading to frequency interference by ZPW-2000A track circuits, focusing on the arrangement of suction lines by power supply engineering, the arrangement of transverse connecting lines by electrical engineering, and an analysis of electrical parameters of track circuits. The factors of frequency interference include substandard digital cables and inappropriate electrical characteristics of tuning units. The solutions are put forward and implemented to eliminate the potential threat to track circuit safety.
