摘要
列车运行在分相区时,处于无电滑行状态,若钢轨轨面生锈,则无法通过牵引电流击穿锈蚀层,使得ZPW-2000轨道电路易出现分路不良现象。针对分相区轨道电路的应用场景,从信号抗干扰性、提高分路灵敏度等角度综合评估,提出了分相区设置轨道区段长度的建议值,为现场工程设计提供参考。
When the train is running in a neutral zone,it is in a state of coasting without electrical power.If the rail surface is rusted,the traction current cannot break through the rust layer.Consequently,ZPW-2000 track circuits are prone to bad shunting.Aiming at the application scenarios of track circuits in the neutral zones,this paper comprehensively evaluates the problem from the perspectives of signal immunity and the improvement in shunting sensitivity,and puts forward the recommended values for setting the length of the track sections in the neutral zones,which provides reference forfield engineering design.
