Claims

[Scope of utility model registration request]

a silicon rectifier that converts AC power input from the commercial frequency power bus into DC power; an inverter that converts regenerative power input from the feeder line back into AC power and regenerates it to the commercial frequency power bus; A stopper diode is inserted into a common bus connecting the DC output side of the rectifier and the DC input side of the inverter, and prevents circulating current from flowing into the inverter from the silicon rectifier, and a stopper diode is connected under the common bus. A line thyristor circuit breaker that supplies line power to each feeder line, and a line thyristor switch and disconnector that are inserted between these line power thyristor circuit breakers and each feeder line and do not have interrupting capability. are inserted in a regenerative circuit connecting each bridge point of the thyrisk switch and the disconnector to the common bus bar, and the regenerative power from the vehicle and the regenerative power from the adjacent substation are connected in series. A group of regenerative diodes that guides the circulating power to the shared bus bar side, a regenerative power that is inserted into the regenerative circuit and guided from the group of regenerative diodes, and a regenerative thyristor breaker that cuts off the circulating power only in the event of an abnormality. A power supply bag for DC electric railways, which is characterized by the following configuration:
