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.
