Definitions

  • the invention relates to an electrical machine with at least one stand which has a winding system, the electrical supply of this winding system being effected via a terminal box of the electrical machine and an electrical line via a connection point to the winding system.
  • the invention is therefore based on the object of optimizing the installation space of a machine and at the same time reducing the assembly effort, in particular in the case of such electrical connections.
  • the problem is solved in that at least the electrical supply line between the terminal box and the connection point takes place via an at least sectionally insulated stranded conductor.
  • a stranded wire consists of individual filaments, which are stranded, twisted, parallel or choke the stranded wire form.
  • the filaments can be laid bare within the stranded conductor, but they can also already have an artificial insulation layer. Even without an artificially applied insulation layer, there is a natural insulation layer on the surface of the filaments in the form of a minimal oxide layer. This means that they have minimal insulation, so that the current inside the stranded conductor is evened out.
  • the stranded wire itself has an insulation layer, at least in sections, in order to be guided close to earthed components of the electrical machine between the terminal box and the connection point on the winding system, without flashovers occurring. Due to its inherent flexibility, the stranded conductor can also be easily and gently laid during installation. In extreme cases, vibrations of the electrical machine do not lead to a broken line. An electrical supply via the stranded wire to the winding system of the electrical machine is therefore possible even under difficult operating conditions.
  • the winding system is also made up of stranded conductors. This means that the switching end of the winding system can be used directly without connection points, e.g. Solder points or clamp connections are led into the terminal box. This eliminates the need for additional solder connections. This leads to a further simplification of assembly.
  • Such an electrical machine is therefore particularly insensitive to the effects of shocks and vibrations, especially with regard to its winding system and its switching connection. occur with railway machines.
  • the stranded conductor between the terminal box and the connection point or the winding system can also be constructed from a plurality of parallel or twisted stranded conductors.
  • the stranded conductors can be manufactured in different cross-sections, but they can also preferably be shaped during assembly so that they can adapt to the given location. Stranded conductors that are embedded, for example, by extrusion in highly flexible materials for insulation are also adaptable.
  • the filaments of the stranded conductor do not consist of the same cross-sections, but have different cross-sections, so that different cross-sectional geometries such as round, triangular, square, polygonal etc. are combined.
  • the density of the filaments of a stranded conductor can thus be increased and its rigidity or flexibility can also be influenced.
  • Compact electrical machines are understood to mean, in particular, railway machines which derive high performance from a relatively small installation volume.
  • FIG. 1 shows the laying of a stranded wire as an electrical connection line within the electrical machine.
  • FIG. 1 shows part of a longitudinal section of a schematically illustrated electrical machine 1, in which a terminal box 2 is located on a housing 3 of the electrical machine 1.
  • a terminal box 2 In this terminal box 2, the supply lines 10 from the terminal box to the connection point 7 are shown in an interconnector via an insulator 5.
  • the switching connection is in the axial extension of the winding head 6, the is in turn located on the end faces of a laminated core 11, shown in principle, of a stator, not shown, of the electrical machine 1.
  • the bushings 13 in the housing 3 can be greatly reduced in terms of their diameter and thus adapted to the diameter of the stranded conductor 10. Due to the advantageous flexibility, i.e. Formability of the stranded conductor 10, the stranded conductor 10 can be adapted in cross section, in particular in the area of the leadthrough 13. Due to the flexibility and deformability of the stranded conductor 10, the end shield 4 can also be optimized accordingly and construction volume can thus be saved.
