Definitions

  • the invention relates to an oscillating throttle according to the preamble of patent claim 1.
  • Chokes of this type are known. They are required for ballasts for fluorescent lamps to stabilize the lamp current and to generate the ignition voltage pulse, the air gap fulfilling the function of avoiding saturation in the working current.
  • the known oscillating chokes have RM or E cores made of ferrite and a single-chamber coil former with a winding made of wound high-frequency braid to avoid eddy currents in the winding to ensure the dielectric strength from start to end (5 kV ss ) and with respect to the core (500 V eff ) on.
  • the required dielectric strength can moreover only be achieved in the known oscillating chokes in that the entire component is also impregnated with insulation. It is obvious that the well-known orbital choke is not cheap to manufacture in the large quantities that the market demands.
  • the invention has for its object to provide a vibrating choke according to the preamble of claim 1, which withstands at least equally good voltage speed with less effort and at the same time even more machine-friendly to manufacture than the known variable inductors and thus a much cheaper mass production than previously possible.
  • the oscillating choke is thus given a higher quality and thus delivers even better ignition pulses, and the eddy current losses are reduced even further by the concentration of the magnetic flux as a result of an adapted configuration of the air gap.
  • the air gap of the core can, however, also be carried out plane-parallel if a linear course of the inductance over the current is a primary requirement.
  • the winding parts 4 and 14 are wound in the chambers ad and fh not adjacent to the air gap in such a way that they are at a greater distance from the neighboring core outer legs than the coil parts in the chambers b, c and e adjacent to the air gap, ie the winding structure is selected in order to achieve voltage security at the beginning and end and against the core in such a way that the former chambers are not as fully wound as the latter.
  • Figure 3 shows on the left at a in side view and on the right at b in section along section line IIIb-IIIb through the side views various other air gap shapes that can be used instead of those shown in Figures 1 and 2.
  • the core shape shown in Figure 3 above gives one linear dependency.
  • the other core shapes are characterized by a step-shaped air gap which is configured in such a way that the stray field is reduced and the inductance, and with it the ignition voltage pulse, is increased with a small modulation.
