SEWERAGE SCHEME OF THE REVERSE TRACTION CURRENT AT THE STATION Russian patent published in 2018 - IPC B60M3/00 

FIELD: electrical engineering.

SUBSTANCE: invention relates to the improvement of reverse traction circuitry. Sewerage scheme of reverse traction current at the station contains the track circuits with insulating joints and impedance bonds, grounding loop of the traction substation and suction feeder. Where the track circuits are separated with the insulating joints into the sections, which are connected between each other using the middle points of the terminals of the impedance bonds, the grounding loop of the traction substation is connected to the midpoint of the outputs of the impedance bonds via the suction feeder and to the ground, the suction feeder is made in the form of individual deep-driven earth rods, which are electrically connected to the ground loop of the traction substation and to each other through the ground.

EFFECT: reliability of power supply to traction consumers is increased and losses in the traction network are reduced.
