ELECTRIC POWER SUPPLY SYSTEM OF RAILROAD HAUL DEVICES OF RAILROAD AUTOMATION Russian patent published in 2021 - IPC B61L1/16 

FIELD: rail transport.

SUBSTANCE: invention relates to means of power supply of railroad haul devices of railroad automation. The system includes a power supply at each of the signal points of the haul, including an inductor connected by terminals to the inputs of the rectifier, the positive and negative terminals of which are connected to the positive and negative terminals of the capacitive energy storage and to similar inputs of the automation and telemechanics equipment, a two-wire line with positive and negative conductors, isolation diodes, station relay contact and auxiliary power supply. In this case, the negative terminal of the auxiliary power supply source is connected to the negative terminal of the capacitive storage of each of the signal points of the route, and the positive terminal through the contact of the station relay is connected to the anodes of the dividing diode of each of the signal points of the route with the help of cathodes connected to the positive terminals of the capacitive energy storage of each of the signal points of the route.

EFFECT: increased reliability of functioning of railroad automation stations at different lengths of inter-train time intervals of trains running on the tracks.
