Definitions

  • the invention relates to a power supply device for explosion-proof electronic functional units.
  • Such energy supply device are used in automation systems for supplying process-related components and associated communication devices.
  • the invention is therefore based on the object to overcome the disadvantages of the prior art and to provide an AC voltage supplying power supply device for explosion-proof electronic functional units that can feed a variety of functional units with little effort.
  • the invention relates to a power supply device for explosion-proof electronic functional units, in which the functional units are fed from a high-frequency alternating voltage, which is individually coupled for each of the functional units via a throttle, which is formed as a multi-level printed circuit board and standing on a distribution board.
  • the multi-level printed circuit board of each choke is covered over its entire area with a flat plate of a magnetic material parallel to the plane of its interconnects.
  • the plate of magnetic material causes an increase in the inductance of the throttle with the same mechanical parameters.
  • the shaping of the magnetic field of the throttle without mechanically elaborate recesses in the multi-level printed circuit board.
  • each throttle consists of two windings with opposite winding sense. This enhances the formation of the magnetic field of the reactor.
  • the chokes can be arranged in high packing density on the distribution board with negligible interference, so that a larger number of chokes are accommodated on the same area of the distribution board. Accordingly, more functional units can be connected to the distribution board with the same dimensions.
  • a power supply device for explosion-proof electronic functional units is shown, in which the functional units are fed from a high-frequency alternating voltage, which is individually coupled for each of the functional units via a throttle 1 .
  • a distribution board 4 having a plurality of chokes 1 is provided, with the chokes 1 standing on the distribution board 4 .
  • the chokes 1 are formed as interconnected, substantially congruent strip conductors 2 of a multi-level printed circuit board 3 . Each one points
  • the chokes 1 are mechanically fixed and electrically contacted on the distribution board 4 .
  • the distribution board 4 on several levels of conductors 2 .
  • each choke 1 is covered over its entire surface parallel to the plane of its interconnects 2 with a flat, field-forming plate 5 of a magnetic material.
  • the field-shaping plate 5 is made of a ferrite material.
  • a field-forming plate 5 is disposed between two adjacent chokes 1 respectively.
  • each throttle 1 is formed in the immediate vicinity of the throttle 1 in such a way that an influence on adjacent throttles 1 is largely avoided.
  • the field-shaping plate 5 magnetic material causes an increase in the inductance of the throttle 1 with the same mechanical parameters.
  • each throttle 1 can be provided to equip each throttle 1 with two windings with opposite winding sense. Thereby, the formation of the magnetic field of the throttle 1 is amplified.
  • the field-forming plates 5 are bonded magnetic material with the chokes 1 .
  • the chokes 1 are housed with the field-forming plate 5 magnetic material.
