Abstract: A device for quick closing of an electric high-voltage circuit. A main spark gap is provided with a first and a second main electrode, and a triggering device. The triggering device includes an auxiliary electrode gap provided with a first and a second auxiliary electrode and is adapted, where necessary, to generate an arc in the auxiliary spark gap for igniting an arc in the main spark gap. Each auxiliary electrode is provided with a guide rail designed such that the arc, via the guide rails and under the influence of the generated inherent magnetic field, moves into the main spark gap. The two guide rails each have a length that is larger than the width of the auxiliary spark gap. The auxiliary electrodes are adapted so as to be protected from the effect of plasma formed in the main spark gap. A hermetic enclosure encloses the main spark gap and the auxiliary spark gap.

Abstract: The invention relates to a device for quick closing of an electric high- voltage circuit. The device comprises a spark gap (1), provided with a first (2) and a second (3) main electrode, and a triggering device (10). The triggering device comprises an auxiliary spark gap (4) provided with a first (5) and a second (6) auxiliary electrode and is adapted, where necessary, to generate an arc (a) in the auxiliary spark gap (4) to ignite an arc (A) in t he main spark gap (1). According to the invention, each auxiliary electrode (5, 6) is provided with a guide rail (13, 14) designed such that the arc, via th e guide rails and while being influenced by the generated magnetic field, move s into the main spark gap (1). The length of the guide rails is larger than th e width of the auxiliary spark gap (4). The auxiliary electrodes (5, 6) are arranged such that they are protected from the effect of plasma formed in th e main spark gap. The spark gaps are enclosed in a hermetic enclosure. The invention also relates to a method and a use.

Abstract: An electric switching device for alternating current comprises two branches ( 2, 3 ) connected in parallel in a current path and having each at least two contact members ( 4-7 ) connected in series. A semiconductor device ( 8 ) is adapted to interconnect the midpoints between the two contact members of each branch. When opening the current path a first contact member ( 5 ) of one, first branch located before said midpoint as seen in the current direction existing is controlled to open and a second contact member ( 6 ) of the second branch located after the midpoint as seen in the current direction is controlled to open for transferring the current to a temporary current path through the semiconductor device. The current path through the switching device is then broken when the semiconductor device is in a blocking state by opening a contact member ( 4, 7 ) of the switching device arranged in the temporary current path.
