Abstract:
1. A device for quick closing of an electric high-voltage circuit, the device comprising: a first main electrode and a second main electrode with a main spark gap therebetween; a triggering device comprising a first auxiliary electrode and a second auxiliary electrode with an auxiliary electrode gap therebetween, the triggering device being configured to generate an arc in the auxiliary spark gap for igniting an arc in the main spark gap, each auxiliary electrode comprising a guide rail each having a length that is larger than a width of the auxiliary spark gap, the guide rails being configured to move under the influence of a generated inherent magnetic field an arc into the main spark gap, and wherein the first auxiliary electrode and the second auxiliary electrode are adapted to be protected from an effect of plasma formed in the main spark gap; a first hermetic enclosure enclosing the main spark gap and the auxiliary spark gap; and a shielding device arranged between the guide rails and the main spark gap.
