Abstract
The invention relates to an overvoltage protection arrangement comprising a horn spark gap located in an insulating housing, with a deionization chamber for arc quenching, wherein the deionization chamber has a plurality of spaced quench plates and a trigger electrode is located in the ignition region of the horn spark gap, wherein a disconnecting device comprises a fusible link that is located in the region of the deionization chamber and is exposed there to a loading of a power follow-on current, wherein the fusible link holds a disconnecting element, preferably supported by spring force, in a first position, and on melting releases this disconnecting element in such a way that the disconnecting element adopts a second position wherein, on reaching the second position, an electrical connection to the trigger electrode is interrupted and the trigger electrode is thereby disconnected.
