MULTIMODE HIGH-VOLTAGE POWER SUPPLY SYSTEM FOR MULTI-SECTION TRAIN AND TRAIN Russian patent published in 2019 - IPC B60L9/14 

FIELD: electricity; transportation.

SUBSTANCE: invention relates to a multi-mode high-voltage power supply system for a multi-section train and a train. Multimode high-voltage power supply system for a multi-section train includes: AC and DC pantograph current collectors, made with the possibility of receiving DC and AC power from the corresponding contact power supply network, an isolation switch configured to determine if the current is supplied to a non-constant current, and interrupting the connection to the DC pantograph current collector in the event of a mismatch, a high-voltage DC unit capable of determining whether the supplied voltage and the supplied current meet the requirement for applying DC power, interrupting the connection with an isolation switch in the event of a mismatch, and a high-voltage AC unit, configured to determine whether the supplied voltage and the supplied current meet the AC power supply requirement, and interrupt the connection to the AC pantograph current collector in the event of a discrepancy.

EFFECT: providing a multi-mode high-voltage power supply system for a multi-section train, configured to supply power to train devices using electricity in different power supply modes in different regions, by determining whether power is supplied in an erroneous mode, and informing the top-level device when energizing in an erroneous mode to correct the wiring.
