Abstract (en)
[origin: WO2009050148A1] The invention relates to a spark gap arrangement for higher rated voltages in which at least two opposite spark gaps comprising electrodes are serially connected and at least one of the spark gaps is introduced actively, i.e., may be triggered, for use as a network arrester that can conduct lightening currents. According to the invention, the spark gaps are located in a pressure-resistant capsule with at least one pressure compensation opening. Also, an insert that bridges the distance between the main electrodes of the passive spark gaps, consisting of a low-impendence material, is provided. Said low impendence material is extremely non-linear in relation to the decreasing residual voltage in the event of a current load.
