Device to get through dead sections in the power supply of electric railway vehicles

摘要

The vehicle (e.g. locomotive) collects current from positive conductor rails (5) on either side through pairs of shoes at the front (1, 3) and rear (2, 4), with earth return through the wheels (27) and running rails (6). All shoes are wired to a storage capacitor (7) and a DC regulator (8) feeding an intermediate circuit (10) which supplies the invertors (12, 15, 19). A traction current invertor (12) for the motors (14) is switched from traction mode into regenerative braking mode while the vehicle travels a distance less than the spacing between the front and rear shoes. An auxiliary supply invertor (19) is also switched (23) out of the train circuit (21).
