The invention provides a 25Hz phase-sensitive track circuit system, which is characterized in that a power transmission end outdoor device takes 25Hz and 220V track voltage signals output by a first power supply as input signals, and outputs adjusted 25Hz signals to power transmission end choke equipment; a voltage signal output by the power transmitting end choke device is input to the power receiving end choke device through the steel rail and then is received by the power receiving end outdoor device. And the power receiving end outdoor device takes the voltage signal output by the power receiving end choke equipment as an input signal, and outputs the adjusted 25Hz signal to the power receiving end indoor device. And the power receiving end indoor device takes the output voltage signal of the power receiving end outdoor device as an input signal, and outputs the filtered 25Hz signal to the receiving equipment. The receiving device receives the track voltage signal output by the power receiving end indoor device and is used for judging the occupied/idle state of the track section where the receiving device is located. The anti-interference capability of the whole system on unbalanced current interference, direct current interference and distortion traction current is improved, and the railway driving safety is effectively guaranteed.

    本发明提出了一种25Hz相敏轨道电路系统,送电端室外装置将第一电源输出的25Hz、220V的轨道电压信号作为输入信号,将经过调整后的25Hz信号输出至送电端扼流设备。送电端扼流设备输出的电压信号经钢轨输入至受电端扼流设备后由受电端室外装置接收。受电端室外装置将受电端扼流设备输出电压信号作为输入信号,将调整后的25Hz信号输出至受电端室内装置。受电端室内装置将受电端室外装置的输出电压信号作为输入信号,将经过滤波后的25Hz信号输出至接收设备。接收设备接收来自受电端室内装置输出的轨道电压信号,用来判断接收设备所处轨道区段的占用/空闲状态。本发明提高了系统整体对不平衡电流干扰、直流干扰和畸变牵引电流的抗干扰能力,有效保障铁路行车安全。
