| 摘要 |
The invention relates to supplying electric traction motors of a rail vehicle with electrical energy. Internal combustion engine/machine combination are operated such that alternating current is generated and used for operating at least one electric traction motor, in a first operating state of the machine in a generator mode. In a second operating state of the machine, an associated machine converter supplies alternating current and drives the associated internal combustion engine, wherein at least the machine converter associated with the second electrical machine is supplied, while the associated electrical machine is in the second operating state, via an electrical DC voltage line with direct current by a rectifier associated with the first machine, wherein the rectifier produces the direct current from alternating current generated by the first electrical machine. |

1. An arrangement for supplying electrical traction motors in a rail vehicle with electrical energy, the arrangement comprising:
at least two internal combustion engines, each having an associated electrical machine for generating the electrical energy, in which the electrical machine is coupled mechanically to the internal combustion engine so that it is driven by the internal combustion engine when the electrical machine is operating in a generator operation so that at least a first and a second internal combustion engine combination are formed, at least one electric traction connection by which a traction motor of the rail vehicle is connectible electrically with at least one of the electrical machines, at least two machine power converters, each associated with one of the electrical machines which supplies the electrical machine with electrical energy during a motor operation of the electrical machine, in which an alternating voltage connection of the machine power converter is connected with the electrical machine, and a control arrangement for controlling at least the operation of the machine power converters, in which a first of the electrical machines is connected electrically with an alternating voltage connection of a rectifier, in which a direct current connection of the rectifier is connected electrically, via an electrical direct current line, with a direct current side of a second of the machine power converters associated with a second of the electrical machines, in which the rectifier rectifies the electrical alternating current generated by the first electrical machine and feeds it, via the direct current line, to the second machine power converter, and the control arrangement is embodied so that it operates the second machine power converter as an inverter in order to supply the second electrical machine with alternating current, while the second machine power converter is supplied with direct current from the rectifier. |
