Definitions

  • the invention relates to a fine control winding for a high-current transformer or a high-current choke coil, designed as a layer winding with at least two parallel branches and partial windings per control stage, which are arranged symmetrically with respect to the center of the winding and which are individually looped axially.
  • the layer winding consists of two or more layers wound radially on one another and the partial windings per control stage consist of partial conductors which are looped axially with respect to one another such that the last turn or part of the last turn a partial conductor in one position is connected to the first turn or a part of the first turn of this partial conductor in a next subsequent position.
  • the cooling of the above-mentioned control windings can be further improved by arranging a cooling gap between two or more layers.
  • the numbers in Figures 1, 2 and 3 are position numbers of the turns in the windings.
  • the numbers in FIG. 4 are position numbers, but also denote the total number of turns per partial conductor from the middle of the winding.
  • the partial winding between the branches SO and S1 is made up of a partial conductor with the external turns 1a, 2a, 3a and the internal turns 4a, 5a, 6a, while the other parallel partial conductor consists of the internal turns 1b, 2b, 3b and the external turns 4b , 5b, 6b is constructed.
  • the partial windings between the branches SO-S1 etc. and SO'-S1 'etc., or each belonging to one of the two branches of the fine control winding are constructed from three parallel partial conductors.
  • the partial winding between the branches SO and S1 made up of a partial conductor with the outer turns 1, 2a, 3a, the turns 4a, 5a and 6a in the middle winding position and the inner turns 7a, 8a and 9a;
  • the second partial conductor is made up of turns 1b, 2b, 3b in the middle winding position, the inside turns 4b, 5b, 6b and the outside turns 7b, 8b; while the third partial conductor is made up of the inner turns 1 c, 2c, 3c, the outer turns 4c, 5c, 6c and the turns 7c, 8c and 9c in the middle winding position.
  • the partial windings between the branches SO-S1, S1-S2 etc. and SO'-S1 ', S1'-S2' etc., respectively belonging to one of the two branches of the fine control winding consist of two parallel partial conductors, with five turns each Subconductors per control stage, of which two and a half turns per subconductor per winding layer.
  • the number of turns per partial conductor is n and the number of winding layers is m, the number of turns per partial conductor per winding layer is -, where n> m> 1 and n and m are integers.
  • n 5
  • m 2
  • the number of turns per partial conductor per winding layer is 2%.
