Abstract (en)
[origin: EP0092870A2] 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).
