  • the second terminal 9 is connected to a second conductor 13 of this high-voltage direct current network.
  • the mechanical switch 7 is shown in the open state, it is assumed in the description below that the mechanical switch (in contrast to the illustration in FIG. 1 ) closed is.

  • the mechanical switch 7 has a very low contact resistance Consequently, occur during the flow of current through the mechanical switch 7 only small electrical losses. Therefore, the device 1 is able to conduct the electrical current in the on state with only small electrical leakage losses.
  • the device 1 also has a turn-off current path 15, which is connected in parallel with the operating current path 5.
  • This Abschaltstrompfad 15 is realized in the embodiment as an electrical series circuit of a power electronic switch 17 and a second winding 19 of a transformer 21.
  • a first winding 23 of the transformer 21 is electrically connected to a supply unit 25.
  • the transformer 21 and the feed unit 25 form a commutation device.
  • the first winding 23 of the transformer 21 is the primary winding
  • the second winding 19 of the transformer 21 is the secondary winding.
  • the first winding 23 and the second winding 19 are galvanically isolated, between the first winding 23 and the second winding 19 is a high-voltage resistant electrical insulation 27 is arranged.
  • the feed unit 25 and the second winding 19 can be realized at a completely different electrical potential.
  • the potential of the second winding 19 (as well as the potential of the mechanical switch 7, the power electronic switch 17, the first terminal 3 and the second terminal 9) can be configured as a high-voltage potential 29, while the first winding 23 and the power supply unit 25 have low-voltage potential 31 exhibit. It is particularly advantageous that the power supply of the supply unit 25 can be made to low-voltage potential 31, whereby an expensive and complex energy supply to high-voltage potential 29 is unnecessary. Furthermore, it is advantageous that the control of elements of the supply unit with low-voltage potential 31 can also take place. The power electronics of the supply unit 25 can thereby also be realized at low-voltage potential or ground potential. So it is only a small amount of insulation for the feed unit 25 is necessary, since this is at low voltage potential or ground potential.
  • the feeding unit 25 generates an electric voltage which is applied to the first winding 23 of the transformer 21.
  • the supply unit is able to influence the voltage occurring at the second winding 19 of the transformer as a result of the induction.
  • the supply unit 25 and the transformer 21 thus serve to introduce into the Abschaltrompfad 15 a voltage which serves as a commutation voltage.
  • This commutation voltage is in FIG. 1 shown with a voltage arrow Uk.
  • the electrical circuit with the mechanical switch 7, the power electronic switch 17 and the transformer 21 form a Kommut réellesschleife the device 1.

  • the mechanical switch 7 and the power electronic switch 17 are closed (switched on).
  • the direct current I1 flows almost completely through the operating current path 5 via the mechanical switch 7, because the mechanical switch 7 has a much lower forward resistance than the power electronic switch 17. If the direct current I1 is to be switched off by means of the device 1, then This is not possible only at a high direct current I1, that the mechanical switch 7 is opened. When switching off a high current I1 alone by means of the mechanical switch 7 namely an arc would arise in the mechanical switch 7, which could damage or destroy it.
  • the direct current I1 is redirected / commutated from the operating current path 5 to the turn-off current path 15;
  • an electrical voltage is applied to the first winding 23 of the transformer 21 by means of the feed unit 25.
  • a current flows through the first winding of the transformer. Due to the current change in the first winding 23 of the transformer, the commutation voltage Uk is induced in the second winding 19. Due to the commutation voltage Uk, a commutation current Ik flows in the commutation loop (i.e., in the loop formed by the operating current path 5 and the turn-off current path 15). This commutation current Ik is directed opposite to the current I1 to be disconnected in the operating current path. By means of this oppositely directed commutation current, the direct current in the operating current path 5 is reduced.
  • the mechanical switch 7 is opened.
  • a characteristic of the direct current I1 can be, for example, the instantaneous value i (t) of the current I1, which is measured in the operating current path.
  • the mechanical switch 7 is not opened until the DC current I1 flowing through the mechanical switch 7 has reached zero. In this case arises in the mechanical switch 7 no arc at all.
  • the mechanical switch 7 can also be opened already when the direct current I1 flowing through the mechanical switch 7 has assumed a small value (for example when the direct current I1 falls below the value of 100A). In this case, while opening the mechanical switch 7 creates an arc.
  • the DC current flowing through the cut-off current path 15 becomes larger and larger.
  • the DC current I1 commutes from Operating current path 5 in the Abschaltstrompfad 15.
  • the power electronic switch 17 is opened and thus the DC I1 off.
  • the power electronic switch 17 is able to absorb the switching energy occurring during the shutdown and convert it into heat energy. Thus, the shutdown of the DC I1 is completed.
  • the device 1 is the FIG. 1 shown with further details.
  • the electronic power switch 17 has a plurality of switching modules 210 connected in series, to each of which an arrester 213 is connected in parallel.

  • the power electronic switch 17 can also be realized so that it has only one switching module 210 with a parallel-connected arrester 213. Then this is a switching module designed such a voltage-resistant that this switching module can accommodate the complete voltage applied to the power electronic switch 17 voltage. However, if the power electronic switch 17 - as in FIG. 2 shown - has a plurality of series-connected switching modules 210, then divides the voltage to be switched on the individual switching modules, so that these switching modules 210 each have to absorb only a lower dielectric strength. As a result, inexpensive switching modules can be used with a lower permissible switching voltage.

  • the current sensor 233 transmits these current measured values to a controller 235, which evaluates the current measured values.
  • the controller 235 recognizes that a characteristic of the current I1 flowing through the operating current path 5 is below a predetermined threshold value, it issues an opening command to the mechanical switch 7.
