Supply of electric traction motors and additional electric auxiliary services of a rail vehicle with electrical energy

摘要

The invention relates to the supply of electrical traction motors in a rail vehicle and of additional electrical auxiliary operations for operating the rail vehicle with electrical energy, wherein: - at least two internal combustion engines (1) are each operated in combination with an associated electrical machine (3), so that at least a first and a second internal combustion engine-machine combination are operated, - the electrical machines generate alternating current driven by the internal combustion engine during generator operation of the respective electrical machine (3), which in a first operating state is generated by at least one generator rectifier (5) rectified and fed as direct current into a direct voltage intermediate circuit (8, 10), - electrical energy is supplied from the direct voltage intermediate circuit (8, 10) to at least one traction motor of the rail vehicle, - electrical in the first operating state Energy is taken from the DC voltage intermediate circuit (8, 10) and supplied to the auxiliary operations (9) via an auxiliary operation inverter (12) and via an auxiliary operation connection (11), in a second operating state in which the auxiliary operation Inverter (12) is out of order and which is an emergency operating state, electrical energy is supplied from the electrical machine (3a) of the first internal combustion engine-machine combination via an electrical emergency operating line (2) to the auxiliary companies (9).
