Definitions

  • the invention relates to a high-frequency transformer with a high operating voltage frequency and high operating voltage difference, with an oxide-ceramic core sealing material, with a winding body made of a winding tube and flanges and of mutually wound, multi-layer windings in the winding space between the flanges, the individual windings wound one above the other by means of insulating films insulated from each other and spacers are provided between the axial coil ends and the flanges, which leave open spaces between the axial winding ends and the flanges.
  • the spacers are designed as spacer blocks, which are distributed along the winding circumference and are guided in radial dovetail guides.
  • the attached spacer blocks are immediately seated in their specified position after being attached. Due to the automatically resulting formation of the free spaces between the axial layer ends and the flanges, connecting wires or connecting tapes can easily be led out to the connections.
  • This construction is extremely flexible for transformer modifications. For example, only different height blocks are required for different winding heights. The leakage current paths are easily extended.
  • the width of the spacer blocks is designed according to the insulation requirements. There is no difficulty in adapting the transformer 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 as required. It is therefore possible to provide either a dovetail guide or simply groove guides.
  • the structure of the holder of the spacer blocks on the coil flanges depends on the manufacturing needs.
  • the drawing shows a diagram of the right half of a transformer with the winding partially cut open.
  • 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.
  • the core yoke is made of oxide ceramic material with two yokes 13 provided on the axial transformer ends and two outer webs 15 and a web 17 passing through the winding tube 5.
  • Connection wires 21 injected into plastic sheaths 19 are provided on the flange 3.
  • 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 and 26, which are joined between the axial winding ends 23 and the coil flanges 3.
  • the high of Spacer blocks 25, 26 correspond to the winding height of the primary winding 9.
  • the spacer blocks 25, 26 are guided in dovetail guides 27 of the coil flange 3.
  • the spacer blocks 25, 26 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 winding 11 is then wound onto the film layer 31, the axial winding ends of which abut against spacer blocks 26 again.
  • the height of the outer spacer blocks 26 also corresponds to the height of the secondary winding 11, and a further insulating film is placed over this winding, including the spacer blocks 26, which is not shown in the drawing.

Claims (2)

1. A high-frequency transformer with a high operating voltage frequency and a large difference between the primary and the secondary voltage, comprising an oxyde-ceramic core material, a bobbin (17) consisting of a winding tube (5) and flanges (3) and multi-layer windings (9, 11) which are wound one onto the other and which are acommodated in the winding space between the flanges (3), the individual windings (9, 11) being insulated from one another by means of insulating foils (31), and spacers (25, 26) being provided between the axial winding ends and the flanges (3), which create clearances between the axial winding ends and the flanges, characterized in that the spacers are constructed as spacing blocks (25, 26) which are distributed along the winding circumference and which are guided in dovetail guides (27).
2. A high-frequency transformer as claimed in Claim 1, characterized in that the width of the spacing blocks (25, 26) is chosen in conformity with the insulation requirements.
