The invention discloses a receiver for a 50HZ phase-sensitive track circuit, and the receiver comprises a matching unit which comprises a transformer and a plurality of capacitor assemblies, a primary winding of the transformer is connected with a relay transformer of the 50HZ phase-sensitive track circuit, and each capacitor assembly is connected in parallel with the primary winding of the transformer; the matching unit is used for performing impedance matching on the 50HZ 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; and the board card group is connected with the secondary winding of the transformer and is used for acquiring the first voltage signal so as to judge the state of the track. According to the invention, phase adjustment of the original voltage signal and the first voltage signal can be realized through the capacitor assembly so as to satisfy one-time adjustment of the track circuit; redundant collection of track signals can be achieved through the board card set, and therefore the reliability of the receiver is improved.
