Claims

[Scope of utility model registration request]

A thyristor rectifier that converts the AC power input from the commercial frequency power bus into DC power, and an Iku-Ichito that converts the regenerative power input from the feeder line back into AC power and regenerates it to the commercial frequency power bus. a stopper diode that is inserted into a common bus connecting the DC output side of the rectifier and the DC input side of the inverter, and that prevents circulating current from flowing from the thyristor rectifier to the inverter side; Two sets of power line thyristor circuit breakers connected under the busbar to feed power line power to each power supply side, and a power line thyristor circuit breaker that is inserted between these thyristor circuit breakers and each feeder line and does not have interrupting ability. and a regenerative circuit connecting each bridge point of the iris switch and the disconnector to the common bus bar, and A group of regenerative diodes that conducts regenerative power from the vehicle and circulating power from an adjacent substation to the shared bus bar side, and a group of regenerative diodes inserted into the regenerative circuit that conducts regenerative power and circulating power in the event of an abnormality. A power supply device for a DC electric railway, characterized in that it is configured with a regenerative thyristor circuit breaker that only interrupts the current.
