FIELD: railway automation.
SUBSTANCE: invention relates to railway automation and telemechanics. Branched rail circuit contains a branched rail line limited by insulating joints, at one end of which a supply transformer is connected, and at two other ends of the branched rail line matching transformers are connected through control resistors. Inductive current limiter is connected to supply transformer. Primary windings of the matching transformers are connected in series and matched to each other and are connected in series with the capacitor and the secondary winding of the insulating transformer, at the same time the other winding of the insulating transformer is connected to the track relay.
EFFECT: increased reliability of branched rail circuit operation due to reduction of relay-contact equipment and cable, while meeting safety requirements for train traffic.
