Definitions

  • the invention relates to an electrical transformer with a magnetizable core, in particular ferrite core, and with at least two cylindrical insulating material winding carriers of different cross-section pushed onto the core and possibly divided into winding chambers, which are plugged into one another and are galvanically separated and wound with the primary and secondary windings.
  • a transformer of this type shows e.g. the FR-A-2457000. This is a high-voltage transformer with U-cores and with two connections on separate sides for the primary and secondary windings, which are cast into a cup to achieve high-voltage strength.
  • GB-A-2039156 also includes a high-voltage transformer, which largely corresponds to the high-voltage transformer according to FR-A-2457000.
  • the problem with this high-voltage transformer is the way in which the connections are led out, which are all on one side, but essei; the pins are at an extremely large, space-consuming distance from each other - fear of voltage flashovers.
  • ferrite material or metal alloy is advantageously used as the material for the core in the above-mentioned transformer for magnetic and economic reasons, it being possible for these two materials to overlap in the area of application.
  • the transformer is of particular importance in that it has the above-mentioned galvanic isolation of primary and secondary windings by inductive coupling, an adjustment of the output resistance of the voltage source to the input resistance of the load is achieved by correct choice of the number of turns, and at the same time voltage and current translations good efficiency can be achieved.
  • the electrical insulation and the primary and secondary windings from one another and the electrical isolation between the primary and secondary windings must be accomplished by the complex and, in particular, time-consuming insertion of insulating foils between the individual windings.
  • the windings on both ends of the winding carriers must be moved, which results in unused winding space.
  • the present invention is based on the object of designing a transformer of the type mentioned at the outset, which can be wound fully automatically by means of an insulating film without the winding insulation and electrical isolation required hitherto and nevertheless complies with VDE regulation 0860.
  • the transformer should have the possibility of variable nesting of the windings; i.e. offer the possibility of using a winding technique that varies from case to case, since this is the only way to achieve optimal coupling and low leakage inductance.
  • the invention proposes an electrical transformer of the type mentioned, in which, according to the invention, the winding carrier of the smallest cross-section has an integrally formed carrier flange with contact pin connection strips for the primary and secondary windings arranged on opposite sides of the carrier flange, as a magnetizable core E-core halves are provided, one E-core half of which engages with its outer legs through openings in the carrier flange and the middle slugs of the two E-core halves are immersed in the enveloped space of the winding carrier of the smallest cross-section.
  • the winding carriers which preferably have an annular cross section, can each be divided into winding chambers, the number and chamber height of which are selected to match the desired nesting of the windings.
  • the potential separation of the primary and secondary windings and the electrical insulation of the individual windings from one another is thus ensured by the thickness of the winding support wall or by the height and thickness of the chamber partition walls.
  • Ring flanges are preferably formed on the end faces of the winding carrier facing away from the carrier flange, such that the flange outer diameter of the winding carrier of smaller cross-section corresponds approximately to the inside diameter of the next following winding carrier of larger cross-section.
  • the height and thickness of the winding carrier flanges and the spatially separate connection of the primary and secondary windings to the contact pins of the opposite contact terminal strips also ensure that the necessary creepage distance is maintained.
  • the optional change in the number and height of the chambers of the individual winding carriers also enables an optimal adaptation of the coupling to the individual application.
  • the fully automatic winding can be carried out without any problems.
  • a further simplified automatic winding is possible if the winding carriers attached to the winding carrier with the smallest cross section are also in several parts.
  • the invention is explained in more detail below using an exemplary embodiment.
  • the single figure shows a winding carrier equipped with a carrier flange and its associated E-core halves in a partially exploded, perspective and partly broken view. For better illustration, the illustration of the windings has been omitted in the figure.
  • a support flange 11 is integrally formed or attached to the front end of the winding support 9 facing away from the flange 17 and has contact terminal strips 12, 13 for contact pins 14 which are separated into individual elements.
  • the partition wall 24 and the carrier flange 11 are provided with open-edge recesses 26, which are used for the positionally secure supply of the winding ends 25 to the contact pins 14.
  • the carrier flange 11 has openings 15 in its area lying between the contact connection parts 12, 13; 16 through which an E core half 2 is guided with its outer legs 6, 7.
  • This and the second E-core half 1 dip in the assembled state with their central slugs 8 and 4, respectively, into the interior of the winding support enclosed by the winding support 9, so that the mutually facing end faces of the legs 3, 6 and 5, 7 lie one on top of the other and the end faces the central slugs 4, 8 are spaced apart to form an air gap.
