Abstract (en)
[origin: WO2017158082A1] The invention relates to a DC voltage switch having a first and second terminal for serial incorporation in a first pole of a DC voltage network, wherein a secondary current path having a semiconductor switch extends between the terminals, and an operating current path having a mechanical switch and, in series therewith, the primary-side winding of a transformer is arranged in parallel with the secondary current path, the secondary-side winding of the transformer is wired between a voltage source and a third terminal for incorporation into a second pole of the DC voltage network, a switch in series with the secondary-side winding of the transformer is arranged between the voltage source and the third terminal, the voltage source is connected to the first terminal via a diode and a charging resistor, there is a control device for driving the switch, which is configured to determine the voltage of the voltage source repeatedly after the mechanical switch has been opened and to switch the switch on at intervals in such a way that the voltage determined remains below a definable threshold value.
