Definitions

  • the invention relates to a line transformer for television sets, consisting of at least one primary and at least one secondary winding, in which at least the winding of the primary winding is wound from a metallic foil with a plastic foil inserted between them as insulation, and which is coordinated in this way that the secondary alternating high voltage contains in particular odd-numbered harmonics> 5th order of the fundamental.
  • Line transformers are known (DE-PS 25 04 355), in which the high voltage generated is kept particularly constant in that the alternating high voltage of the line transformer is tuned to odd harmonics > 5th order.
  • both the primary and the secondary winding (high-voltage winding) are designed in chamber winding technology, ie the windings are wound on a coil former, the winding space of which is divided into several chambers.
  • the high-voltage winding in the conventional flyback transformer is divided into three partial windings of which in each case two partial windings on the seventh harmonic and a part Wick-L u ng are tuned to the fifth harmonic. This K.Fraunhofer 7-6
  • the primary winding has an uneven density distribution, which is realized in such a way that the primary winding is also divided into a plurality of chamber windings which have different numbers of turns.
  • This object is achieved in that the coordination is divided into a coarse and a fine tuning in such a way that the coarse tuning by changing the width, the axial position and / or the radial position of the metallic foil of the primary winding and the fine tuning an inhomogeneous winding density distribution of the high-voltage winding is brought about.
  • the tuning of the alternating high voltage to the desired resonance frequencies is already approximately achieved.
  • the fine tuning takes place by means of a different winding density of the high-voltage winding, which is wound, for example, from wire onto a bobbin provided with chambers.
  • the specified measures allow the alternating high voltage of a line transformer to be matched to odd-numbered harmonics> 5th order with less effort than with the known line transformer.
  • the proposed teaching can be applied both to those line transformers whose primary and secondary windings are implemented using film winding technology, and to those line transformers whose secondary windings are implemented using chamber winding technology.
  • FIG. 2 shows the actual construction of a line transformer according to FIG. 1.
  • This contains the so-called film winding 1 and the coil body 2, which has a plurality of chambers in which the part windings W 1 , W 2 and W 3 are arranged as wire windings. The ends of the partial windings are routed to soldering points at which the diodes are also soldered.
  • the film roll 1 lies in the coil body 2.
  • FIG. 3 The longitudinal section through such a finished line transformer is illustrated in FIG. 3, in which the foil winding 1 and the coil former 2 are arranged on a base 3 and in a housing 4.
  • the high-voltage winding consists of the partial windings W 1 , W 2 and W 3 , with which the diodes D 1 , D 2 and D 3 are connected in series in the manner shown in FIG. 1.
  • the high-voltage connection 5 is led out of the housing 4 at the upper end, while all the other connections are led to socket pins 6, only one of which is shown for simplicity.
  • the primary winding A is particularly highlighted in FIG. 3 as part of the film winding 1. It has the width L, which is less than the total width W available for the film roll 1.
  • the coarse tuning can be further improved by the axial and / or radial position of the primary winding A. Radial position of the primary winding A means that the primary winding A can assume any local position in the film winding between R2 and R1. Axial position of the primary winding A means that the primary winding A with the width L can assume any local position along the total width W.
  • the partial winding W 1 is tuned to the 5th harmonic and the partial windings W 2 and W 3 to the 9th harmonic of the alternating high-voltage fundamental wave.
  • the fine tuning that is also required can be achieved by deliberately introducing inhomogeneous winding density distribution in the high-voltage winding. This can be done, for example, in that different numbers of turns are present in the individual chambers of the coil former on which the partial windings of the high-voltage winding are wound.
