In an embodiment a device includes a first arrester unit with at least one first gas-filled surge arrester and a second arrester unit with at least one second gas-filled surge arrester, wherein the first and second arrester units are connected in series with one another between a first potential node and a reference potential node, wherein the first arrester unit and the second arrester unit are different from each other, wherein the first arrester unit includes a larger response voltage than the second arrester unit, and wherein the first arrester unit includes a smaller arc voltage than the second arrester unit.

Device for discharging over voltages and its use

An arrester such as an arrester for protection against overvoltages is disclosed. In an embodiment an arrester includes a housing configured to act as an external electrode, a central electrode arranged completely within an inner region of the housing, a discharge region arranged between the central electrode and the housing, a ceramic body separating the housing and the central electrode, wherein the ceramic body is arranged in an offset manner relative to the discharge region and a shielding element arranged on an inside of the housing, and wherein the shielding element extends over an entire longitudinal extent of the central electrode along the inside of the housing.

Arrester for protection against overvoltages

An arrester for surge protection is disclosed. In an embodiment, an arrester for surge protection includes a first electrode, a second electrode, a discharge chamber for enabling an electrical discharge between the electrodes in an event of an overvoltage and an insulator forming an inner wall of the arrester, wherein the inner wall has a projection.

Arrester for surge protection

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.

Multiple spark-gap arrester

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.

Spark gap arrangement
