Abstract

See full text

The invention relates to an arrangement for firing spark gaps with a trigger electrode which is located at or in one of the main electrodes and which is insulated from this main electrode, wherein the trigger electrode can be electrically connected to a further main electrode via at least one voltage-switching or voltage-monitoring element and there is an air gap between the trigger electrode and the further main electrode, wherein the trigger electrode forms a sandwich structure with an insulating layer and a layer made of a material with lower conductivity than the material of one of the main electrodes. Moreover, the insulating layer is designed as a thin foil or lacquer layer and the layer made of the material of lower conductivity is in contact with one of the main electrodes or rests on it. According to the invention, for discharging energetically weak overvoltage events without response of the spark gap formed between the main electrodes, the insulating layer of the sandwich structure is interrupted outside the firing area and/or an electrical component which influences the response behavior is connected between the trigger electrode and the associated main electrode.
