Definitions

  • the invention relates to an electrical transformer with a magnetizable core and with an insulating material winding support pushed onto the core for the galvanically separated primary and secondary windings.
  • ferrite material or metal alloy is advantageously used as the material for the core 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 carrier are 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 option 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 transmitter of the type mentioned at the outset, which according to the invention has at least two cylindrical winding carriers of different cross-section and any cross-sectional shape, which are plugged into one another and each wound with the primary or secondary windings.
  • 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.
  • the winding carrier of the smallest cross-section has on one end face a one-piece molded or also plugged-on carrier flange which has contact terminal strips, in particular on opposite sides, in particular contact pin terminal strips for the primary and secondary windings.
  • Ring flanges are preferably formed on the end faces of the individual winding carriers 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 respective 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 the coupling to be optimally adapted 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 additionally 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 was omitted in the figure.
  • a carrier flange 11 is integrally formed or attached to the front end of the winding carrier 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, 16 in its area lying between the contact connection parts 12, 13, 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, which is enclosed by the winding support 9, so that the mutually facing string surfaces of the legs 3, 6 and 5, 7 lying one above the other and the end faces the central slugs 4, 8 are spaced apart to form an air gap.
