Abstract

PURPOSE:To set a counter-plan properly against the abnormal state of a rectifier, by switching control for converting AC power to DC power, to a spare rectifier, when the abnormal state of an arbitrary rectifier is detected among a plurality of rectifiers. CONSTITUTION:By the thyristor rectifier of a three-phase bridge connection, an AC breaker 1 is connected to a power main-circuit, and by a controller 11 and change-over control, power is fed to a phase shifter, and the power is fed to respective thyristor arms 3U-3W, and power feed is interrupted if command is OFF. To the arms 3U-3W, two thyristor elements are respectively connected in parallel with each other, and power is fed to the stringing P of an electric rolling stock. Then, earth abnormal-state detectors 5U-5W are arranged accommodated t. the thyristor arms 3U-3W respectively, and when element destruction is generated, then the output of detection signal is directed to the controller 11. Breakers 7U-7W, 9U-9W are also arranged on the respective arms in the same manner, and power feed is controlled by the controller 11.
