本发明涉及一种过电压保护装置，其包括位于绝缘壳体中的角火花间隙(1)，该角火花间隙具有用于灭弧的消电离室(4)，所述消电离室具有多个间隔开的灭弧板(9)并且触发电极(7)位于角火花间隙的点火区域中，分离装置具有熔断丝(8)，该熔断丝位于消电离室区域中并且在那里承受由电网续流引起的负荷，所述熔断丝将优选由弹簧力辅助的分离元件(15)保持在第一位置中并且在熔化时这样释放该分离元件，使得分离元件占据第二位置，其中，在到达第二位置时中断与触发电极(7)的电连接并且因此分离触发电极。 The invention relates to an overvoltage protection arrangement comprising a horn spark gap located in a housing, with a chamber for arc quenching, wherein a trigger electrode is located in the ignition region of the horn spark gap, wherein a disconnecting element is provided that interrupts a connection between a trigger circuit and the trigger electrode, and thus disconnects the trigger electrode, wherein the disconnecting element is tripped or controlled by an evaluation unit that is subject to and reacts to the loading of a power follow-on current.
