摘要
轨道电路是铁路信号的重要基础设备,其性能直接影响行车安全和运输效率。因此保证轨道电路的可靠工作,在降低自身故障的前提下,如何避免和克服其他外部因素造成的故障也是在设计和施工阶段应该考虑的重点问题。就集中监测系统绝缘测试组合电路引起的轨道电路故障进行分析和处理,提出在不改变现有设计和增加继电器的条件下,通过增加智能分析功能解决和规避此类故障风险的方法。
Track circuit is an important basic equipment for railway signals,and its performance directly affects driving safety and transportation efficiency.Therefore,to ensure the reliable operation of the track circuit,how to avoid and overcome the failures caused by other external factors under the premise of reducing its own failures is also a key issue that should be considered in the design and construction stages.This paper analyzes and deals with the track circuit faults caused by the combined circuit of the insulation test of the centralized monitoring system,and proposes a method to solve and avoid such fault risks by adding intelligent analysis functions without changing the existing design and adding relays.
