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 the 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 the guide rails and while being influenced by the generated magnetic field, moves into the main spark gap (1). The length of the guide rails is larger than the 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 the main spark gap. The spark gaps are enclosed in a hermetic enclosure. The invention also relates to a method and a use.
