Patent ID: 8873217

Claim:
Arrangement for the ignition of spark gaps, comprising a trigger electrode (T) located on or in one of the main electrodes (H 2 ) and insulated from this main electrode (H 2 ), wherein the trigger electrode (T) is electrically connected to the other main electrode (H 1 ) by at least one voltage-switching or voltage-monitoring element and an air gap is provided between the trigger electrode (T) and the other main electrode (H 1 ), characterized in that the trigger electrode (T) forms a sandwich structure with an insulation section (I) and a layer made of a material (M) which has a lower conductivity than the material of one of the main electrodes (H 1 , H 2 ), the sandwich structure representing a layered dielectric in the series connection of a first partial capacitance (CI) to the dielectric of the insulation section (I) and a second partial capacitance (CM) to the material (M) as the dielectric, and the first partial capacitance (CI) and/or the second partial capacitance (CM) are chosen to be very small.
