摘　　要：ZPW-2000A轨道电路在铁路信号系统中运用的十几年里,以其故障导向安全为基本前提,其稳定的工作性能得到电务部门的一致认可。但近年来,伴随铁路大发展,轨道电路系统需在全国各种复杂环境中稳定运行,其中道床漏泄电阻大小影响轨道电路稳定运行,严重的道床漏泄将会引起区段红光带,影响列车运行,就此提出了相应的建议及方案。Over the past decade,ZPW-2000A track circuits have been used in railway signal systems,with the fail-safe principle as the basic premise,and their stable working performance has been unanimously recognized by the signal&telecommunication departments.However,in recent years,with the rapid development of railways,the track circuit systems need to operate stably in various complex environments across China.The value of the leakage resistance of the ballast affects the stable operation of the track circuits.Severe ballast leakage will cause red-light straps to occur in the sections,affecting train operation.Therefore,corresponding suggestions and solutions are proposed.
