摘　　要：通过选取兰渝线ZPW-2000A/K型轨道电路道床漏泄严重情况和“红光带”状况的轨道电路区段,通过搭建轨道电路仿真计算模型与实地采样对比测试验证分析在25μF和50μF两种补偿电容配置下的轨道电路常规性能,评估两种配置下ZPW-2000A/K型轨道电路对低电阻道床的适应能力,研究增强ZPW-2000A/K型轨道电路在低电阻道床漏泄环境下运行能力的有效方法。By selecting the sections of the Lanzhou-Chongqing Railway equipped with ZPW-2000A/K track circuits experiencing serious ballast leakage and"red-light strap"condition,a simulation calculation model of the track circuits is built and compared withfield sampling to verify and analyze the regular performance of the track circuits by performing tests under the two compensation capacitor configurations:25μF and 50μF.For both of the configurations,the adaptability of ZPW-2000A/K track circuits to low-resistance ballast is evaluated,and a scheme is proposed to effectively enhance the operation capability of ZPW-2000A/K track circuits under low-resistance ballast leakage conditions.
