基于通信编码的区间ZPW-2000轨道电路最小道砟电阻取值探讨

Discussion on Minimum Ballast Resistance of ZPW-2000 Track Circuit Based on Communication Code

轨道电路是完成列车占用、空闲检查的安全设备,道床的最小道砟漏泄电阻率是确定轨道电路设备选型和设计标准的重要参数。本文对基于通信编码的区间ZPW-2000轨道电路在不同线路标准下的道床最小道砟电阻取值进行了探讨,给出更合理的取值,以保障行车效率并有效降低工程造价。

The track circuit is the safety equipment for checking the occupation and idleness of the train.The minimum ballast leakage resistance of the track bed is an important parameter for determining the type selection and design standard of the track circuit equipment.In this paper,the minimum ballast resistance value of ZPW-2000(communication code)series track circuit under different line standards is discussed,and a more reasonable value is given to ensure the train working efficiency,and reduce project cost effectively.
