Abstract
A switch for a high-voltage direct current transmission path includes a vacuum circuit breaker for disconnecting the transmission path and a gas-insulated circuit breaker for disconnecting the transmission path. The gas-insulated circuit breaker is connected in series with the vacuum circuit breaker. A device is provided for building up a counter-current against the current in the transmission path for the purpose of reducing the current across the vacuum circuit breaker. The elements of the switch are actuated by a control device in such a way that the switch is switched off at or close to the zero crossing of the current.
