The invention discloses a receiver for a 25 HZ phase-sensitive track circuit, and the receiver comprises a matching transformer which comprises a primary coil and a secondary coil. A primary coil of the matching transformer is connected with a relay transformer of the 25HZ phase-sensitive track circuit, and the matching transformer is used for carrying out impedance matching on the 25HZ phase-sensitive track circuit so as to convert an original voltage signal of the track circuit output by the relay transformer into a first voltage signal; the ratio of a primary coil to a secondary coil of the matching transformer is 1: 1; and two board cards, each of which is connected with the secondary coil of the matching transformer and is used for collecting the first voltage signal so as to obtain the state of the track. Redundant collection of track signals is achieved, the fault guiding safety side is met, and the reliability of the receiver is effectively improved.

    本发明公开了一种用于25HZ相敏轨道电路的接收器,包括:匹配变压器,其包括一次线圈和二次线圈;所述匹配变压器的一次线圈与所述25HZ相敏轨道电路的中继变压器进行连接,用于对所述25HZ相敏轨道电路进行阻抗匹配,以将所述中继变压器输出的轨道电路的原始电压信号转换为第一电压信号;且所述匹配变压器的一次线圈和二次线圈的比值为1:1;以及两个板卡,每一所述板卡与所述匹配变压器的二次线圈进行连接,用于采集所述第一电压信号,以获取所述轨道的状态。本发明实现了对轨道信号的冗余采集,满足故障导向安全侧,有效提高了接收器的可靠性。
