Definitions

  • the invention relates to a transformer according to the introductory part of patent claim 1.
  • the invention allows a space-saving, compact transformer structure with sufficiently large distances between the high-voltage windings to achieve reliable mutual insulation.
  • the subclaims relate to preferred configurations of the transformer according to claim 1.
  • ferrite or iron powder core 1 and 2 has a two-part ferrite or iron powder core 1, either designed as a U-U core or as a U-I core, on the two legs 2 of which a one-piece chamber bobbin 3 or 3 'is arranged in the exemplary embodiment.
  • the two chamber bobbins 3, 3 ' are identical to one another and arranged on the core 1 in such a way that they are parallel to the drawing plane of FIG. 2 and to the drawing plane of FIG. 1 vertical center plane M of the core 1 are arranged symmetrically.
  • the primary winding of the transformer is divided in half between the two bobbins 3, 3 ', the winding halves P / 2 being located in the lowest chamber a of the respective bobbin 3 and 3' for the viewer of FIGS. 1 and 2, respectively.
  • the two high-voltage windings are divided into the chambers b1-b5 of each chamber bobbin 3 or 3 ', the thickness d of the chamber base b' surrounding the respective core leg 2 b 'in the chambers b1-b5 from those for the primary coil halves P / 2 provided chambers a gradually increases away from chamber to chamber.
  • the bobbins 3, 3 ' are wound in the chambers b only to such an extent that between the high-voltage winding carried by the bobbin 3 on the one hand and the high-voltage winding carried by the bobbin 3' of opposite polarity on the other hand, there is a sufficiently large insulation distance everywhere.
  • the core 1 has a right-angled, in the exemplary embodiment square cross section, and the coil formers 3, 3 'are adapted to this cross section, as can be seen in particular in FIG. 3a.
  • the coil formers 3, 3 ' are in one piece in the illustrated embodiment, but this is not a mandatory requirement.
