Abstract

The invention relates to an arrangement for igniting spark gaps with a trigger electrode T which is located on or in one of the main electrodes H2 and is insulated with respect to this main electrode H2, wherein the trigger electrode T is electrically connected to one of the other main electrodes H1 by means of at least one voltage-switching or voltage-monitoring element and there is an air gap between the trigger electrode T and the other main electrode H1. According to the invention, the trigger electrode T forms a sandwich structure with an insulation section I and a layer which is composed of a material M with a lower conductivity than the material of one of the main electrodes, wherein this sandwich structure represents a layered dielectric with the order of a first partial capacitor CI with the dielectric of the insulation section I and a second partial capacitor CM with the material M as dielectric.
