Embodiment Construction

[0035] figure 1A diesel engine 1 driving a generator 3 is shown in FIG. The generator 3 generates a three-phase alternating current which is rectified by the rectifier 5 . The rectifier 5 is connected to a DC voltage intermediate circuit 7 . With the help of P-UD+ (intermediate circuit 7 in figure 1 upper side shown in ) and P-UD- (intermediate circuit 7 in figure 1 The lower side shown in ) represents the DC voltage—the potential of the intermediate circuit 7 . The potential P-UD- can be connected to the vehicle ground at the point indicated by the reference number 19 .

[0036] Connected to the intermediate circuit 7 are a traction inverter 9 that supplies power to the four drive motors 17 of the rail vehicle through a three-phase connection, a brake circuit breaker 11 connected to a braking resistor 12, and a three-phase AC line to the Auxiliary operating equipment-inverter 13 , which supplies power from auxiliary operating equipment 18 , and load-inverter 15 , which s...

Abstract

The invention relates to the operation of an arrangement for supplying devices of a locomotive with electric energy. During normal operation of the arrangement, electric energy is converted from a DC voltage intermediate circuit (7) by at least one traction converter (9) in order to supply at least one drive engine (17) of the locomotive with electric energy. Furthermore, auxiliary systems (18) of the locomotive are supplied by an auxiliary converter (13) with electric energy from the DC voltage intermediate circuit (7). During extraordinary operation of the arrangement, electric energy from an AC voltage net is supplied to a transformer (14) of the arrangement by a AC voltage connection (21), the electric energy is transformed by the transformer (14) to a higher voltage level, the energythat was up-transformed is fed by the auxiliary converter into the DC voltage intermediate circuit (7) and at least one drive engine (17) of the locomotive is supplied with electric energy from the DC voltage intermediate circuit (7) by the traction converter (9).

Description

technical field [0001] The invention relates to a device for supplying electrical energy to equipment of a locomotive. The invention also relates to a locomotive with such a device and a method for operating such a device. [0002] The invention relates both to a locomotive with a unit for supplying traction energy from an electrical supply network and to a locomotive with an internal combustion engine for generating electrical energy for traction. Background technique [0003] A locomotive is to be understood as any rail vehicle which has its own traction means, that is to say has at least one traction motor. The term refers in particular to an independent vehicle that can be coupled to a train set of rail vehicles, but can also refer to a machine in which both equipment for generating traction and space for goods and / or people are present in the same vehicle or vehicle area. car or train. In particular, the devices generally necessary for the generation of traction (for...
