A protection arrangement for transferring electric power to a power consumer

摘要

An arrangement (1) for transferring electric power from a power source in particular to a driving motor of a railroad vehicle comprises a direct current intermediate circuit (9) with two direct current connection lines (13,15), at least one of which is connected to the power source, and a current converter (11) for inverting a direct current and for delivering alternating current power to the power consumer (5). The current converter is connected to the direct current connection lines (13,15). At least one capacitor (17 to 20) is provided in the intermediate circuit (9). A first pole is connected to the first direct current connection line (13) and the second pole is connected to the second direct current connection line (15). At least one fuse (21 to 24) is connected in series to the capacitor or to at least one of the capacitors (17 to 20), so as to connect the first (13) and second (15) direct current connection lines via the capacitor (17 to 20). A pantograph 3 may connect an AC supply to a rectifier 7 which supplies the inverter 11.
