摘要
The invention relates to an over-voltage protection arrangement comprising a horn gap (1) located in an insulating housing having a deionization chamber (4) for arc extinguishing, wherein the deionization chamber has a plurality of extinguishing plates (9), which are spaced apart from each other, and a trigger electrode (7) is located in the ignition region of the horn gap, wherein a disconnecting device has a fuse element (8), which is located in the region of the deionization chamber, and is subjected to a load there caused by power follow current, wherein the fuse element holds a, preferably spring force supported, disconnecting element (15) in a first position and releases said disconnecting element upon melting, such that the disconnecting element assumes a second position, wherein, upon the second position being reached, an electrical connection to the trigger electrode (7) is interrupted and the trigger electrode is thus disconnected.
