Definitions

  • the invention relates to a diesel-electric vehicle, in particular a rail vehicle with a diesel generator.
  • Vehicles in particular rail vehicles, which are designed as traction vehicles, are always used with a diesel engine as a primary energy source when the track was not electrified due to lack of load.
  • the key issues with using a diesel engine as a traction drive are the inability to start torque at startup, such as electric motors or steam engines, and the relatively tight binding of power and speed at low consumption.
  • the object of the invention is to provide a supply of the auxiliary plants in a simple manner, using galvanic isolation and observing the applicable protective regulations.
  • the solution of the object is achieved by a diesel-electric vehicle, in particular rail vehicle, with a diesel generator is designed as a permanent-magnet synchronous generator, which is provided with a stand provided in a stator winding, which has a traction winding and one of them electrically isolated auxiliary winding.
  • the additionally electrically isolated auxiliary winding in the stator of the diesel generator which is designed as a permanent-magnet synchronous generator, is no further isolating transformer, which is reflected in costs, in mass and in installation space, necessary for the auxiliary plants. Also, no additional power semiconductor devices with increased reverse voltage are necessary.
  • auxiliary windings are interleaved with the traction winding of the stator of the permanent-magnet synchronous generator. That the auxiliary operating winding is located at least in sections with the traction winding in the same slots of the stator.
  • predetermined portions of the stator are occupied only by the auxiliary operating winding.
  • the auxiliary operation winding is concentrated in the grooves of a portion of the permanent-magnet synchronous machine.
  • the relationship between the numbers of nubs or poles respectively occupied for the traction winding and the auxiliary winding is determined by the ratio of the traction and auxiliary powers.
  • Both winding arrangements ie a distributed auxiliary operating winding as well as the concentrated auxiliary winding lead to comparatively higher winding upper fields, which generally lead to larger machine losses in the rotor and in the stator. Therefore come for highly utilized and at the same time designed for efficiency asynchronous generators and electrically excited conventional generators with damper cage such rotors out of the question. This would lead to high balancing currents in cage rotors.
  • the edge effects lead from the transition of the traction winding to the auxiliary operating winding and, conversely, to comparatively high losses in the case of asynchronous generators and conventional synchronous generators.
  • the rotor of the permanent-magnet synchronous machine is relatively well suited due to the proposed arrangement of the auxiliary operating winding, which leads to increased rotor losses in conventional generators, since the winding upper and / or edge effects have no parasitic effects on the rotor, which ultimately result in increased heat output would. This manifests itself in particular by the fact that when using the dental coil technology in the permanent-magnet synchronous machine which also causes harmonics, the runners are less lossy.
  • auxiliary winding operation and the traction winding are concentrated in the area of the stator of the permanently excited synchronous generator, wherein a predeterminable number of the existing pole pairs form the galvanically separated auxiliary winding.

  • FIG. 2 shows a structure similar to FIG. 1, wherein an auxiliary operating winding 6 in the stator of the diesel generator 2, in addition to the traction winding 5, is to be provided for the electrical feeds of the auxiliary drives 9 completely by the normal stator winding, in this case the traction winding 5.
  • This auxiliary operation winding 6 must Among other things, to avoid pendulum moments and losses in the damper cage of this conventional diesel generator 2 as the traction winding 5 be constructed, ie the same number of coils with the same coil width. Thus, this Hilfs seswickwick- 6 is very expensive to produce and therefore expensive.
  • FIG. 3 shows, in a further alternative already known, the supply of the auxiliaries 9 directly from the traction intermediate circuit 18, wherein the auxiliary converter 10 must be constructed with power semiconductors of corresponding blocking voltage and a transformer 12 is to be provided in order to ensure electrical isolation. Both the corresponding power semiconductors and an additional transformer are reflected in the costs and also in the mass as well as the electrical losses.
  • auxiliary operating converter 10 shows the supply of the auxiliary operating converter 10 by a pulsed DC voltage from the traction intermediate circuit 18 by means of a step-down converter, which is formed by a chopper 14 and a throttle 13.

  • FIG 6 now shows an inventive arrangement with a diesel generator, which is designed as a permanent-magnet synchronous generator with a simple, galvanically separated auxiliary winding 6 in the stator 30 of the synchronous generator in addition to the traction winding 5.

  • the auxiliary 9 are fed with otherwise dissipated in the braking resistors energy. This energy is transmitted inductively into the auxiliary operating winding 6 and thus supplies the auxiliary 9th.
  • the auxiliary gear 9 must not be powered by the diesel engine 1 in electric braking with energy, which has an additional fuel savings result.
