The invention belongs to the technical field of track circuits, and particularly relates to a phase-sensitive track circuit which comprises an indoor sending unit, an indoor receiving unit, receiving equipment and an outdoor choke transformer. Indoor concentrated voltage and phase regulation is achieved, the workload of equipment installation, debugging and maintenance is reduced, and the overall power consumption is reduced on the premise that the overall power consumption is not increased. According to the invention, the rail surface voltage and the shunt sensitivity can be improved, and the shunt characteristic of the system is improved. According to the invention, the anti-unbalance traction current interference capability of the electrified section is improved from 100A to 150A, the anti-DC magnetization current reaches 30A, the problem of rail section flashing caused by unbalance and impact current interference is reduced, the transportation safety is ensured, and the transportation efficiency is improved. The electrified section and the non-electrified section are both provided with the choke transformers, the track circuit system is unified, equipment is not added during superposition coding, and the consistency of track circuit adjustment is guaranteed.
