Gas discharge surge arrester

摘要

A surge arrester which has activating compound applied in recesses outside of an ignition gap. The distance between the recesses of two electrodes in the surge arrester is distinctly greater than the width of the ignition gap form by the electrodes. The ignition gap is not effected by deforming of the activating compound and therefore an associated change in the ignition voltage does not occur. These surge arresters are particularly suited for very small electrode spacing.
