Abstract: A multiple spark-gap arrester is disclosed. In an embodiment the arrester includes a series connection of a plurality of spark gaps between a first potential node and a reference-ground potential node and a trigger circuit having an input and an output, the input being coupled to a second potential node between two adjacent spark gaps of the plurality of spark gaps, and the output being coupled to at least one of the spark gaps between the second potential node and the reference-ground potential node, wherein the trigger circuit is configured, when at least one spark gap between the first potential node and the second potential node is ignited, to supply a trigger signal for the at least one of the spark gaps between the second potential node and the reference-ground potential node.

Abstract: A surge arrester includes a gas-tight discharge chamber that is formed by at least one insulating body and two electrodes. The electrodes extend into the discharge chamber and include an electrode spacing with respect to one another and a wall spacing with respect to the insulating body inner wall. The electrode spacing is equal to twice the wall spacing or is less than twice the wall spacing.

Abstract: A surge arrester comprises an electrical insulator (10), which surrounds a cavity (20), a pin electrode (30) and a tube electrode (40), which are arranged in the cavity (20), wherein the pin electrode (30) projects into the tube electrode (40). An ignition strip (50) is applied on an inner surface (S10a) of the insulator facing the cavity (20). An outer metallization (61, 62, 63) is arranged on an outer surface (S10b) of the insulator (10). As a result, an effective reduction of the protection level can be achieved in the case of the surge arrester.

Abstract: A spark gap arrangement includes a triggerable spark gap and a trigger circuit. The spark gap arrangement also includes a first and a second charge storage device, a voltage limiting component, a trigger diode, a triggerable arresting element, and a transformer. The voltage limiting component and the trigger diode are designed to relay an input pulse in a specified voltage range and charge the first charge storage device. Furthermore, the trigger circuit is designed such that the triggerable arresting element is connected via the first charge storage device dependent on the voltage and discharges the second charge storage device via a primary side of the transformer.
