Definitions

  • the invention relates to an arrangement for electrically isolated energy transmission according to claim 1.
  • These components can e.g. Switching elements, electronic modules or measuring points, which must be isolated from the earth potential.
  • the energy transmission takes place primarily wirelessly, for example via the so-called “Radio Frequency Identification (RFID)” technology or via optical fibers.
  • RFID Radio Frequency Identification
  • the received power is well below one watt, mostly in the 100mW range. This is because the diode-based rectifiers used for this have limitations with regard to current and voltage peaks and heat dissipation. For this reason, it is only possible to supply a consumer with low power consumption.
  • the GB 2185860 A a dielectric waveguide, to which a stub is connected with a probe which projects into the dielectric waveguide and to which a rectifier diode is attached.
  • the US 2012/0133306 A1 discloses a waveguide for an accelerator with a dielectric wall and the like US 3746424 discloses an optical dielectric waveguide connected to an electrical sensor on a high voltage line.
  • the object of the invention is to provide an arrangement which overcomes the disadvantages of the aforementioned solutions.
  • the arrangement according to the invention for the galvanically separated energy transmission with voltages in the high-voltage range is designed in such a way that the energy transmission takes place through a dielectric waveguide. This ensures that the power received, that is to say the power intended for consumers, is significantly higher, namely up to 10 watts or higher, than is possible in the prior art.
  • the dielectric waveguide is preferably configured in such a way that it has a functional connection with at least one first rectifier device and at least one second rectifier device such that the first rectifier device has a conductive along the length of the dielectric waveguide on the input side to a first coupling point located along the length of the waveguide Has connection and the second rectifier device on the input side to a located along the length of the waveguide coupling point has a conductive connection and have a distance to the signal input of the waveguide and to each other.
  • the transmitted power is decoupled before the end of the dielectric waveguide, the second decoupling point or any further decoupling point with rectifier device being able to be arranged at the end.
  • the division of the power is generated by the different distances, which is then passed on to the respective consumer via the rectifier device.
  • n is the number of consumers / decoupling points
  • the arrangement is developed such that the configuration of the decoupling of the first decoupling point and / or the distance of the first decoupling point from the signal input of the waveguide and the configuration of the coupling-out of the first coupling-out point and / or the distance between the first coupling-out point and the signal input of the waveguide are designed such that the value of a power drawn at the first and second coupling-out point is the same.
  • At least one electrically insulating shielding device is arranged on the dielectric waveguide extends the so-called creepage distance, i.e. the path of electrical currents which are usually caused by environmental influences, in particular on the surface of the dielectric, and thereby the loss minimized.
  • the insulating shielding device is configured in such a way that its dielectric constant is smaller than the dielectric constant of the dielectric waveguide and is attached directly to the waveguide.
  • the low dielectric constant ensures that the directly attached shielding device does not, at least not disturb, the properties of the dielectric waveguide.
  • the invention may be advantageous to develop the invention in such a way that the insulating shielding device is arranged in such a way that a space-generating element is created between the dielectric waveguide and the shielding device Distance exists.
  • the dielectric constant of the shielding device is greater than or equal to the dielectric constant of the dielectric waveguide.
  • this space is filled with in particular a solid, liquid or gaseous insulation medium, in particular with a dielectric constant that is lower than the dielectric constant of the dielectric waveguide, since space is generally available will be and a corresponding filling can usually be used advantageously.
  • a solid, liquid or gaseous insulation medium in particular with a dielectric constant that is lower than the dielectric constant of the dielectric waveguide
  • the waveguide is preferably formed from at least one as an angular and / or round, rod-shaped body. This is advantageous, for example, because it is well researched and can therefore be modeled with regard to optimal function, in particular transmission values.
  • the arrangement is designed such that at one end of the dielectric waveguide mentioned, in particular designed as a coaxial cable or microstrip, waveguide transition is functionally connected.
  • the transmission can take place at high frequency and its effect according to the invention can develop, particularly in the high-voltage range, it will be advantageous to further develop the invention in such a way that the dielectric waveguide is formed from materials, in particular aluminum oxide or Teflon, with a dielectric constant> 1.
  • the efficiency of the energy transmission is increased further, since radiation, that is to say unwanted power loss, is reduced.
  • a first embodiment variant CYLINDRICAL and a second embodiment variant RECTANGULAR are both solid bodies which are elongated in the form of a rod, the first embodiment variant CYLINDRICAL having a round cross section, while the second embodiment variant has a rectangular cross section.
  • the rod-shaped solid bodies shown are CYLINDRICAL and RECTANGULAR can also be formed by stringing together to form a longer overall construct.
  • HV high-voltage
  • the exemplary embodiment shown can be developed in such a way that the frequencies of the high-frequency signal are within the ISM band 2.45 GHz and 5.8 GHz. It is also advantageous to use a material with a low tan ⁇ in such a frame of the transmission frequency for efficient energy transmission.
  • the dielectric constant ⁇ r is chosen as high as possible.
  • Example materials with which this development according to the invention is achieved are aluminum oxide or Teflon.
  • the dielectric waveguide DIELEKTRISCHER_WELLENLEITER shown in the exemplary embodiment has the property of not only supplying one consumer TERMINAL DEVICE, but several, since according to the invention power can be coupled out before the end of the DIELEKTRISCHER_WELLENLEITER conductor and fed to another consumer.
  • this arrangement has the property that not only an energy required for switching can be transmitted, but also data such as time information, since the high-frequency electrical signals of the HF source HF_SIGNAL_GENERATOR can be used for this.
  • the dielectric waveguide shown is used according to the invention by emitting high-frequency electromagnetic waves in the mm-waves or microwave range in a round or square (cf. Figure 1 ) rod-shaped material with a dielectric constant> 1 leads.
  • this rod uses the electromagnetic wave at the same time both energy and a communication signal, e.g. the timing signal can be transmitted, the rod is transmitted to the frequency generator (signal source) HF_SIGNAL_GENERATOR with a suitably selected and modulated output power of the frequency generator HF_SIGNAL_GENER via a so-called waveguide transition, such as a coaxial cable, also microstrip line or similar devices that provide this function connected.
  • a so-called waveguide transition such as a coaxial cable, also microstrip line or similar devices that provide this function connected.
  • a rectifier device RECTIFIER is supplied to the respective consumer or, in the simplest case, without structuring the material of the waveguide DIELEKTRISCHER_WELLENLEITER, in connection with metallic conductor structures, can be coupled out.
  • the energy transported in the waveguide DIELEKTRISCHER_WELLENLEITER decreases in accordance with the decoupled power.
  • the first decoupling is considered weaker than the subsequent ones (represented by the smaller dimension of the slot or the opening), in order to realize, for example, that the extracted one at all decoupling points Performance has the same value if desired.
  • 1 watt (W) could be extracted per decoupling point with a total signal power of 3 W, so that the first decoupling must be 1/3, the second 1/2 and the third 1, for example in relation to the dimension.
  • the possibility of providing the waveguide with shields that is, to be encased, for example, by an insulator.
  • This variant is in the Figure 4 recognizable on the left. If the ⁇ r of the insulator HOCHSPANNUNGS_ISOLATOR is small compared to that of the waveguide DIELEKTRISCHER_WELLENLEITER and thus the properties are not affected, this HOCHSPANNUNGS_ISOLATOR shield can be attached directly to the DIELEKTRISCHER_WELLENLEITER waveguide (not shown). When the HIGH VOLTAGE ISOLATOR screen is at a certain distance as shown.
  • a solid, liquid or gaseous insulation medium can generally be introduced in this space created by the distance, and in such a way that the properties of the DIELEKTRISCHER_WELLENLEITER waveguide do not lead the electromagnetic wave in the dielectric is affected, but rather the transmission is even optimized.
  • the in the Figure 4 The meander structure of the dielectric waveguide DIELEKTRISCHER_WELLENLEITER indicated on the right extends the path of the creepage distance by shaping the waveguide DIELEKTRISCHER_WELLENLEITER and can therefore also do without the HIGH VOLTAGE ISOLATOR.
