轨道电路一次参数的两次短路测量方法

摘要

轨道电路是关系到列车运行安全的重要基础设备,其中一次参数的测算是信号工程设计和检修中的一项经常性工作.针对传统的开路、短路法,已不能适用的情况,文中提出了利用"两次短路法"测算轨道电路一次参数的方法.实际测算结果表明:采用"两次短路法"及其相应的计算软件,轨道电路一次参数的测算方法可靠,测算工作简单,并且精度较高,具有良好的应用前景.%Track circuit is important basic equipment related to the safety of train operation.The measurement of track circuit primary parameters is a regular work in the design and maintenance of signal systems.In view of inapplicability of the traditional open circuit and short circuit methods, this paper presented a method to measure and calculate track circuit primary parameters using the "twice short circuit method".The actual measurement and calculation results proved the reliability, simplicity, high precision and a good application prospect of the calculation method using the "twice short circuit method" and the corresponding calculation software.
