The invention relates to a spark gap having a plurality of individual spark gaps connected in series and present in a stacked arrangement, spaced apart from each other by insulating spacers (5) and nearly free of secondary current under typical operating conditions, wherein the individual spark gaps comprise electrodes (4) and outer connection electrodes are provided, and further having control elements for influencing the voltage distribution across the stacked arrangement and/or designed as an ignition aid. According to the invention, a mechanically pretensioned insulating element (8) can be inserted or pivoted between two adjacent electrodes (4) of the individual spark gaps, in order to interrupt the main current path of the spark gap in case of fault or overload.
Spark gap having multiple series-connected individual spark gaps, which are placed in a stacked arrangement and spaced apart from each other by insulating or high-impedance spacers, and being almost follow-current-free under normal operating conditions, wherein the individual spark gaps include electrodes and external connection electrodes are provided, and further having control elements for influencing the voltage distribution over the stacked arrangement and/or designed as an ignition aid, characterized in that
