摘要
国内某些既有普速线ZPW-2000A轨道电路存在调整电压、分路残压过高的现象,严重时会导致占用丢失,影响行车安全。选取几个典型的占用丢失区段,用m a t l a b进行建模仿真计算,分析不同道砟电阻值对轨道电路调整的影响,并提出降低调整电压的方法,为后续解决彻底该类问题提供思路。
Some Zpw-2000a track circuits in China existing normal speed lines have the phenomenon of high adjustment voltage and high residual voltage,which will lead to occupation loss and affect traffic safety in serious cases.This paper selects several typical sections with occupation loss for modeling and simulation calculation with maltab,analyzes the influence of different ballast resistance values on the track circuit adjustment,and proposes the method of reducing the adjustment voltage to provide ideas for solving such problems in the future.
