Definitions

  • the magnetic fluff within the individual windings is thus determined by the air gap within the winding, while the air gap is kept as small as possible in the central web common to the two coils, so that the magnetic coupling of the two coils to one another reaches a minimum order of magnitude, that of a separate one Use of the two coils zF with different Preceunzen permits.
  • this surface is optimally level thanks to special work processes.
  • the object of the invention is to provide a coil with several windings for different applications with only one iron core.
  • magnetic fields of different sizes are generated by two coils connected in series and arranged next to one another on a body with the same inductance depending on the polarity of the coils to one another when an AC voltage is applied in the common coil axis. If the coils are polarized in the same direction, this magnetic field reaches a certain value, whereas if the polarity is in opposite polarity, the resulting magnetic field is not or hardly detectable.
  • This knowledge is used in solving problems in a coil arrangement with a pin core in order to realize coils for different tasks and with different frequencies.
  • a third winding is arranged between the side-by-side, series-connected magnetically polarized windings, this winding is approximately free of field lines of the outer windings and can be used as a separate coil.
  • it is expedient to arrange the coil with the larger inductance in the center since when a pin core is used, this coil is fully immersed and there are no inductance losses as with the outer coils due to the mutually polarized windings.
  • Manufacturing tolerances can be compensated for during manufacture by moving the pin core, so that the outer windings have exactly the same inductances and, when an AC voltage is applied, large magnetic fields directed against one another.
  • the reverse polarity of the outer windings causes losses in inductance. Despite these inductance losses, the outer windings will have sufficient inductance. emerge. achieved by stray fields.
  • the winding 1 shows a coil with three windings 2, 3 and 4 with the winding connections 6, 7, 8 and 9.
  • the windings are arranged next to one another on a winding body 5.
  • a magnetizable pin core 1 which is adjustable in its position relative to the windings.
  • the outer windings 2 and 4 are arranged in such a way that the pin core approximately closes with the outer edges of the coil. They are connected in series so that they act magnetically in opposite directions. The direction of the magnetic fields is indicated by the field lines. Due to the distance between the outer windings 2.4 and their polarity, the magnetic coupling of these windings to one another is such that sufficient inductance can still be achieved.
  • the decoupling of the winding 3 is optimal if the pin core 1 is set so that the magnetic fields of the outer windings 2.4 are the same. Since the pin core. : 1 fully immersed in the middle winding 3, the field lines of this coil close in the manner shown, the direction of the field lines and the frequency applied can be selected. The middle winding 3 induces currents in the outer windings which are the same size and cancel each other out by the opposite polarity.
  • Fig. 2 shows part of a horizontal deflection circuit in a television g et up instrument with an input 10, the deflection coils 11,12, the linear adjuster 14, the tangent of the capacitor 15, the bridge coil 16, the parallel capacitor 17, the diodes 18,19, the return capacitors 20, 21, the east-west drive coil 22 and the east-west circuit 23.
  • the middle winding 3 is used as an east-west control coil with approx. 6 mH and the series connection of the outer windings 2.4 as a bridge coil with approx. 1.7 mH in a television set.
  • the outer windings 2, 4 can be wound in the same winding direction or in opposite directions to one another. If different wire diameters are to be used, it is cheaper to arrange the east-west control coil in the outer chambers and the bridge coil in the middle chamber.
  • FIG. 4 shows a part of a vertical deflection circuit in a television set with a vertical integration coil 2, 4 and the control part for a horizontal deflection circuit with a line driver transformer 3.
  • pulses for controlling the current in the horizontal deflection coils are supplied from a pulse generator. They are amplified in transistor 40, the collector of which is connected to a connection of primary coil 31 of row driver transformer 3. The other connection is on the supply voltage + UB. The pulses arrive from the secondary coil 30 at the input of the line end transistor 43, from whose collector connection C the horizontal deflection coils (not shown) and the line transformer are driven.
  • Thyristor 36 is to be understood as a switch by means of which the horizontal flyback pulses applied to the series connection of the vertical deflection coils 40 with the vertical integration coil 2, 4 in time with the horizontal frequency are switched from the winding 39 of the line transformer, which is also in series.
  • the vertical integration coil 2, 4 the course of the vertical deflection voltage is shaped such that lines are written on the screen with the same vertical spacing.
  • the coils 30, 31 and 2.4 are arranged on a pin core, which is indicated by the connecting, dashed line for the common iron core.
  • FIG. 5 shows the arrangement of the windings for the line driver transformer 3 and for the vertical integration coil 2, 4 according to FIG. 4th
  • the winding core 5 with five winding chambers has the iron core 1 arranged in the form of a pin core approximately centrally to the chambers.
  • the outer chambers take the opposite direction together wound partial coils of the vertical integration coil 2.4.
  • the row driver transformer is housed in the three middle chambers.
  • the secondary winding 30 is located as the lower winding close to the iron core.
  • the winding distribution is chosen so that the middle chamber receives a larger number of secondary turns than the adjacent chambers, which enables an optimal field distribution, so that mutual interference between the row driver transformer and the vertical integration coil can be minimized. Because of the larger wire diameter and also because of the high currents, it has proven to be expedient to arrange the secondary coil in the lower winding layers of the three middle chambers. It is expediently wound with the same wire that is also provided for the vertical integration coils.
  • the primary winding 31 is applied as the last winding to the secondary winding 30 underneath.
