Definitions

  • the invention relates to a transformer, in particular with an oxide-ceramic core sealing material, with a winding body made of winding tube and flanges and of multi-layer windings wound on one another in the winding space between the flanges, the individual windings wound one above the other being insulated from one another by means of insulating foils and spacers between the axial ones Coil ends and the flanges are provided.
  • Transformers are particularly sensitive to leakage currents at higher operating voltages, higher operating voltage differences and higher operating frequencies. Special precautions must therefore be taken to extend the leakage current paths.
  • spacer blocks are of simple design and make it possible, by forming the free spaces between the axial layer ends and the flanges, to lead connecting wires or connecting strips to the flanges and the connections.
  • This construction is extremely flexible for transformer modifications and is particularly suitable for automation of the winding processes. For example, only different height blocks are required for different winding heights.
  • the width of the spacer blocks is designed according to the insulation requirements. There is no difficulty in adapting the transformer width to other insulation requirements by changing the spacer block width.
  • the transformer structure is suitable for both round and square changing rooms.
  • the guides of the spacer blocks on the coil flanges can also be modified according to requirements. So it is possible to provide either a dovetail guide or simply groove guides. Gluing would also be conceivable when working without a guide.
  • the structure of the holder of the spacer blocks on the coil flanges is based only on the manufacturing needs.
  • the drawing shows a diagram of the right half of a transformer with a partially cut winding.
  • the FXC transformer consists of a coil former 1, flanges 3 and a winding tube 5 connecting the flanges.
  • the winding space 7 between the flanges 3 and the winding tube 5 is wound, for example, with a primary winding 9 and a secondary winding 11.
  • Oxide-ceramic material is used for the core yoke with two yokes 13 provided on the axial transformer ends and two outer webs 15 as well as a web 17 passing through the winding tube 5.
  • connecting wires 21 are provided in plastic sheaths 19.
  • the primary winding 9 of the transformer is first wound onto the winding tube 5.
  • the axial ends 23 of this winding abut against spacers 25 which are joined between the axial winding ends 23 and the coil flanges 3.
  • the height of the spacer blocks 25 corresponds to the winding height of the primary winding 9.
  • the spacer blocks 25 are guided in dovetail guides 27 of the coil flange 3.
  • the spacer blocks 25 are thus fixed on the coil flanges 3.
  • two spacer blocks are located opposite one another at a winding end 23. It would also be conceivable, for example, to work with three spaced-apart blocks.
  • the spacer blocks thus leave open spaces 29 between the axial layer ends 23 and the flanges. These free spaces are well suited for leading out the coil connections.
  • an insulating film 31 is placed over the primary winding 9, which extends over the spacer blocks 25 to the coil flanges 3.
  • the secondary layer is then on the film layer 31 winding 11 wound, the axial winding ends abut against spacer blocks 25 again.
  • the height of the outer spacer blocks 25 corresponds to the height of the secondary winding 11, and a further insulating film is placed over this winding, including the spacer blocks 25, which is not shown in the drawing.
  • the spacer blocks 25 are extremely simple to manufacture and can be widened or narrowed, increased or flattened in accordance with the desired transformer types and can also be fixed in any manner with guides other than dovetail guides on the coil flanges.
