Abstract:
A direct current switching device for interrupting an electric direct current flowing along a medium or high voltage current path. An electric circuit arrangement has a mechanical switching device connected in the current path and a circuit unit for forcing a zero-crossing point in the mechanical switching device. The circuit unit has multiple capacitive components and a switch which are connected in the circuit unit such that, in a first switching state of the switch, the capacitive components are connected in parallel for a respective electric charging process via the medium or high voltage current path and, in a second switching state of the switch, the capacitive components are connected in series in order to generate a current pulse which forces the zero-crossing point. The direct current switching device is useful for interrupting an electric direct current flowing along the medium or high voltage current path.

Claim (Index 20):
A method of interrupting a direct electric current flowing along a medium or high voltage current path, the method comprising:\n providing a switching device with an electric circuit arrangement including at least one mechanical switching device connected in the medium or high voltage current path and with at least one switching unit configured to force a current zero crossing in the mechanical switching device connected in the medium or high voltage current path; providing the at least one switching unit with a plurality of capacitive components and a switch; operating the switch in a first switching state wherein the capacitive components are connected in parallel for a respective electrical charging process via the medium or high voltage current path; and operating the switch in a second switching state by connecting the capacitive components in series to generate a current pulse which forces the current zero crossing; and interrupting the direct electric current flowing along a medium or high voltage current path by switching the at least one mechanical switching device at the current zero crossing.
