Claims

[Scope of utility model registration request]

It is divided by multiple forward power converters consisting of silicon rectifiers operated in parallel and converting AC power into DC power, a DC bus bar connected to the output side of these forward power converters, and this DC bus bar and a dead section. A power running thyristor circuit breaker is inserted in series in each of the electric lines connecting the first and second overhead contact lines, and a separate dead section is installed at a predetermined pressure distance from the dead section on either one of the first and second overhead contact lines. A third overhead contact line formed by providing sections, a regeneration diode inserted in an electric path connecting the third overhead contact line and the DC bus, and a cathode side connected to the anode side of the regeneration diode. A power supply device for a DC electric railway, further comprising a pair of thyristor switches each having its anode side connected to the cathode side of the power running thyristor circuit breaker.
