Abstract
A switching apparatus comprises: a plurality of parallel-connected current-conductive branches, each current-conductive branch including at least one respective gas tube switch; and a switching control unit configured to control the turn-on of the gas tube switches in a switching order so that the flow of current in the switching apparatus is controlled to switch between the current-conductive branches, wherein the switching order of the turn-on of the gas tube switches is arranged so that only one of the current-conductive branches is carrying the current during each turn-on cycle of the switching apparatus.
