RAIL TRACK CIRCUIT PROTECTION DEVICE Russian patent published in 2024 - IPC B61L23/16 

FIELD: railway automation and telemechanics.

SUBSTANCE: invention relates to the field of railway automation and telemechanics, in particular to sensors of information on the vacancy and occupancy of railway tracks with alternating current electric traction, which are electric rail track circuits. Device includes a rail line limited by insulating joints, at the ends of which choke-transformers traction windings are connected, and to additional windings of choke-transformers track circuit equipment is connected, middle points of traction windings of choke-transformers of adjacent rail line are connected through in-series connected to each other inductance and capacitance, which form resonance circuit. Capacitance can be made in the form of capacitor, inductance in the form of traction half-windings of choke-transformers.

EFFECT: improving operating reliability of rail track circuits at alternating current electric traction by means of elimination of false occupancy at glaze ice phenomena on contact wire and meeting requirements for traffic safety in control mode of track circuit operation.
