【摘要】This paper introduces the structure and basic principle of FTGS--917 type of track circuit. Through testing the signal transmission process of two different frequency amplifier and filter boards, the specific circuit principle and the difference between them are obtained. In addition, the relation between the amplitude of output signal and the load of amplifier and filter board are analyzed. The results of this test and analysis provide significant value of reference in the investigation of FTGS type of track circuit.%介绍了FIGS-917型轨道电路的结构组成和基本原理.通过现场对两种频段的放大滤波板信号传输特性进行测试,确认了放大滤波板的具体电路原理以及两种型号放大滤波板的差异,并分析了输出信号幅值与外电路负载的关系.该单元的测试分析结果对于研究FTGS轨道电路有一定的参考价值.
