摘　　要：不对称高压脉冲轨道电路目前已在全国各路局的分路不良区段广泛应用,在解决分路不良问题方面取得了显著的效果。目前现场广泛应用的不对称高压脉冲轨道电路,脉冲发送器均没有进行冗余设置,脉冲发送器故障将导致区段红光带,影响铁路运输效率。尤其是安装在室外的脉冲发送器,故障处理恢复时间长。针对不对称高压脉冲轨道电路脉冲发送器冗余方式进行研究,提出可行的冗余措施,进一步提高不对称高压脉冲轨道电路可用性、可维护性。Asymmetric high voltage pulse track circuit has been widely used in the poor shunting sections of railway administrations in China,and has achieved remarkable results in solving the problem of poor shunting.At present,the pulse transmitter of asymmetric high voltage pulse track circuit widely used in the fi eld has not been set up redundantly.The fault of pulse transmitter will lead to the red light band of the section and aff ect the effi ciency of railway transportation.Especially the pulse transmitter installed outdoors takes a long time to recover.This paper studies the redundancy mode of pulse transmitter in asymmetric high voltage pulse track circuit,and puts forward feasible redundancy measures to further improve the availability and maintainability of asymmetric high voltage pulse track circuit.
