Definitions

  • the present invention relates to a high-voltage machine with a laminated core, which has a plurality of grooves, and a winding, which is arranged in the grooves and made of a stranded conductor and having at least one strand.
  • the invention relates in particular to high-voltage motors and generators in stranded conductor design. According to the VDE regulations, high-voltage machines are designed for operating voltages of 3.3 kV and more.
  • the circuit is preferably realized by solder joints, or when using stranded conductors by Crimptheticen.
  • a stranded conductor consists of a plurality (typically several hundred, possibly more than a thousand) of individual lacquer-coated individual conductors which are wound with a main insulation made of mica tapes.
  • the paint layer must be completely removed from the individual wires.
  • the individual conductors must not be damaged, in particular not bent, broken off, etc.
  • Each connection (coil connection or switching connection) within a stranded winding represents a weak point. Due to poor current transitions, so-called hot spots occur with these connections. These weaknesses can usually not be eliminated by high effort.
  • the lacquer layer was previously removed by burning, brushing and chemical treatment.
  • the object of the present invention is therefore to propose a high voltage machine with reduced axial length, which is suitable for operation at high speeds.
  • this object is achieved by a high-voltage machine with a laminated core, which has a plurality of grooves, and a winding which is arranged in the grooves and made of a stranded conductor and has at least one strand, wherein the entire, at least one strand continuous is inserted with a single stranded conductor in the grooves of the laminated core.
  • the invention allows a strand or a phase with a single stranded conductor (endless conductor) without coil connections and insert without switching connections in the grooves of a laminated core. Since no coil or switching connections are provided, there is no additional space required for the circuit.
  • the stranded conductor preferably has more than one hundred lacquer-coated individual conductors. In many cases, the stranded conductor also consists of four hundred individual conductors and more, sometimes even more than a thousand individual conductors. As a result, the displacement effect that occurs at higher frequencies can be reduced to a tolerable level, so that even higher-speed machines can be realized.
  • the individual conductors of the stranded conductor can be wound with a main insulation made of mica tape. This makes it possible to realize a voltage-proof insulation.
  • the winding in the high-voltage machine can have several layers in each individual groove of the laminated core. This makes it possible to achieve correspondingly high inductances.
  • the at least one strand may have a plurality of coil groups.
  • FIG. 1 shows a winding pattern of a phase U of a two-pole high-voltage machine according to the invention
  • FIG. 3 shows a winding pattern of a phase W and 4 shows a circuit diagram of the stator of the high voltage machine with the windings of Figures 1 to 3 from the axial view.
  • FIG. 1 shows the winding diagram of a first strand, in this case phase U.
  • a single, continuous stranded conductor with the ends U1 and U2 is placed in the grooves 34 to 36 and 1 to 6 and 16 to 24 according to FIG.
  • the stranded conductor which has, for example, four hundred insulated individual conductors and is designed for more than 3.3 kV, is inserted into the groove 1.
  • the stranded conductor is continued to groove 24, and then to the grooves 2, 23, 3 and 22.
  • a first winding layer of a first coil is placed.
  • a coil is placed in the grooves 4, 5, 6, 19, 20 and 21.
  • a strand piece L1 which is part of the stranded conductor, connects the two coils.
  • a second winding layer is placed in the same grooves 1 to 6 and 19 to 24.
  • the second winding layer is integrally connected to the first winding layer with a strand piece L2.
  • This strand piece L2 is as well as the strand piece Ll for connecting the first coil on the B side BS of the winding.
  • no coil or switching connections are provided here.
  • the first four coils are now formed in the first winding layer WLl and the second winding layer WL2 each with a radial projection.
  • the stranded conductor After the stranded conductor has been guided for the second time through the groove 24, it is guided to the groove 34 on the B-side BS with another strand piece L3 which takes the place of a switching connection. Now, the grooves 34 to 36 and 1 to 3 and 16 to 21 are occupied in the same manner with the stranded conductor as the previous grooves. The winding layers WL3 and WL4 are created in these grooves. Finally, the stranded conductor is guided out of groove 21 to the outside and it forms there an end U2.
  • the winding diagram of FIG. 1 leads to a two-pole machine (compare the circuit diagram of FIG. 4).
  • the stranded conductor for the phase V with the ends Vl and V2 is inserted in an analogous manner according to FIG 2 continuously in the grooves 10 to 18 and 28 to 36. Again, corresponding winding layers WL1 to WL4 are formed. The ends Vl and V2 of the stranded conductor thus protrude on the side BS of the grooves 13 and 33 to the outside.
  • the stranded conductor also forms the winding layers WL1 to WL4 here.
  • the ends Wl and W2 protrude here from the grooves 9 and 25 on the side BS.
  • FIG. 4 shows the circuit diagram of this winding from the B side BS.
  • the grooves 1 to 36 four coil layers can be seen in each case.
  • the Litzenleiterstucke are shown in FIG 4, as Serve switching connections. Coil connections are not shown.
  • the Litzenstucke L2 and L3 are drawn, which connect the first layer of the groove 19 with the second layer of groove 6 and the second layer of groove 24 with the third position of groove 34.
  • the individual phases UVW are not merged into a star point, but for the selected case of need, each alone with two ends is led to the outside.

Abstract

L'invention vise à mettre au point un moteur haute tension pour hauts régimes, de longueur très réduite dans le sens axial. A cet effet, il est prévu d'insérer un conducteur de phase (U, V, W) de manière continue, conjointement avec un seul conducteur multibrins, dans les rainures (1 à 36) du noyau feuilleté d'un moteur haute tension. Ce système permet de ne plus avoir recours à des connexions par bobines et à des connexions de couplage, ainsi qu'à des lignes en boucle, qui induisent de manière générale un porte-à-faux marqué de la tête de bobine.
