ELECTRICAL JOINTS FOR BRANCHED RAIL CIRCUITS Russian patent published in 2019 - IPC B61L23/16 E01B11/54 

FIELD: electricity.

SUBSTANCE: group of inventions relates to the construction units of rail circuits to regulate the movement of trains. Electrical joint contains a capacitor connected to the rails via a track transformer, a track transformer was connected for create a circuit joint to a single track rail at a distance that allows for a fixed frequency of the signal current, a transformation ratio of the track transformer, and a capacitor capacitance to provide current resonance in the circuit to prevent the signal current from spreading to the adjacent rail segment. Wiring diagram of the boundary electrical joints for branched rail circuits contains capacitors connected to the rails via a track transformer, a spandrel beam is additionally installed between the rails, and the connection of the track transformer for create boundary junctions is carried out at a distance that allows, at a fixed frequency of the signal current, the transformation ratio of the track transformer, and the capacitance of the capacitor, to provide current resonance in the circuit to prevent the current from flowing into the adjacent rail line.

EFFECT: increase in the reliability of the station rail circuits is achieved.
