Definitions

  • the present invention relates to a device for
  • an electrical / electronic circuit which usually has to be operated in the low-voltage range.
  • Such an electronic circuit can be arranged close to or directly on the high-voltage line and serve to detect electrical or non-electrical variables, test purposes and the like.
  • Such electronic circuits are usually operated with a supply voltage in the range of 2 to 15 V, which, however, can not readily be made available on the high-voltage line.
  • an apparatus for operating an electronic circuit at a high voltage potential.
  • the device includes a diode array disposed in a high voltage line such that a current flowing over the high voltage line flows through the diode array.
  • the electronic circuit is applied to the voltage drop across the diode array, and provides information determined at the high voltage line.
  • An evaluation unit is connected to the electronic circuit via a galvanically separated transmission device in order to receive the determined information.
  • One idea of the present invention is to arrange on a high voltage line a diode array, over which a nearly constant voltage drops when on the
  • High voltage line an electric current flows in a certain current range.
  • the voltage can be used to operate an electronic circuit which can be arranged directly on the high-voltage line, without this having to be galvanically separated.
  • the diode arrangement comprises a series circuit of one or more diodes, in particular zener diodes.
  • a capacitor can be connected in parallel with the diode arrangement.
  • the transmission device may comprise an optical waveguide or a radio link.
  • the electronic circuit may include a temperature sensing circuit connected to a temperature detector.
  • the evaluation unit may have a ground potential.
  • the single figure shows a block diagram of the device 1 for operating an electronic circuit 4 to high voltage potential according to the present invention.
  • the device 1 is arranged on a high voltage line 2.
  • the high voltage line 2 is designed to carry high voltage potentials, e.g. for voltages over 1000 volts, preferably for voltages around 100kV.
  • An electronic circuit 4 is understood in this description to mean any electrically operable device.
  • the high-voltage line 2 is provided with a diode arrangement 3, which is arranged in the high-voltage line 2. As soon as a small current flows on the high-voltage line 2, this also flows through the diode arrangement 3, so that via the diode array 3, a certain voltage, the diode voltage drops. The voltage is tapped via corresponding connection points in front of and behind the diode arrangement 3 and applied to an arranged on the high voltage line 2 electronic circuit 4 to operate them.
  • the diode array 3 can be formed for example of a diode chain with one or more conventional diodes, a series circuit of one or more zener diodes or the like.
  • the illustrated embodiment is a Zener diode.
  • the Zener diode is doing in the reverse direction in the high voltage line
  • a capacitor 5 may be provided in parallel to the diode array 3, which smoothes the voltage applied to the electronic circuit 4 voltage.
  • the electronic circuit 4 need not be galvanically isolated from the high voltage line 2, so that the circuit therein is substantially at or near the high voltage potential applied to the high voltage line 2. There then prevail in the electronic circuit 4 only voltage differences in the height of the diode array above
  • the electronic circuit 4 may be provided, for example, to provide operational quantities, e.g. to determine a temperature of an arranged on the high voltage line 2 arrangement by means of a temperature detector 7 or this itself or to measure the current flowing through the high voltage line 2 current. The electronic circuit 4 then provides the corresponding measured values. Alternatively, the electronic circuit 4 may also comprise a test circuit providing test values relating to the operation of arrangements arranged on the high voltage line 2.
  • the measured values or the test values are transmitted to an evaluation point 6, which is operated essentially in the area of the ground or ground potential.
  • the transmission takes place with the aid of a transmission device 8 so that the electronic circuit 4 and the evaluation point 5 are galvanically separated from each other.
  • Possible devices for transmitting the measured values or test values between the electronic circuit 4 and the evaluation point 5 can be realized, for example, with the aid of an optical waveguide or a radio transmission of the corresponding measured values or test value.
