HZ Phase Sensitive Track Circuit

- Oct 18, 2018-

Circuit characteristics:
1.  Use 25HZ power supply as the signal source of track circuit.
2.  Use 25HZ to exchange two yuan two bit track relay. This relay is not only selective in frequency but also has phase selectivity. Its phase selectivity ensures reliable inspection of the short circuit of the insulation section.
3.  Track relay has two coils, namely, track, local coil (local advance orbit 90 degrees). Strong anti-interference ability.
