25 Hz相敏轨道电路调整方法探讨

Discussion on Adjustment Method of 25 Hz Phase Sensitive Track Circuit

轨道电路是构成铁路信号联锁系统的重要基础设备,能监督线路的占用情况,反映列车运行的位置。25Hz相敏轨道电路因设备简单耐用、电路结构清晰及故障率低等优点,被广泛应用于电气化区段。因此,结合现场多次调整试验,设计出一套快速、精确的调整方法,为联锁试验的顺利进行奠定了基础,确保了车站的正点开通。

Track circuit is an important basic equipment of railway signal interlocking system. It can monitor the occupancy of railway lines and reflect the position of train operation. 25 Hz phase-sensitive track circuit is widely used in electrified section of our country because of its simple and durable equipment,clear circuit structure and low failure rate. Therefore,combined with many adjustment tests on the site, a set of rapid and accurate adjustment methods was designed to lay the foundation for the smooth progress of the interlocking test and ensure the on-time opening of the station.
