- eine Aufsicht auf die Lichtbogenelektrode gemäss Fig.2.
Tritt bei Betrieb des Überspannungsableiters in einer Hochspannungsanlage zwischen den Stromanschlüssen 3 und 6 am Aktivteil und/oder am Isolator 1 ein unerwünschter Störlichtbogen auf, so werden dessen Fusspunkte (vgl. Fig.3, in der einer der beiden Fusspunkte mit dem Bezugszeichen 19 versehen zusammen mit dem Speisestrom I des Störlichtbogens dargestellt ist) unter der Wirkung seines eigenen magnetischen Feldes jeweils an eine der beiden Lichtbogenelektroden 4 und 7 geführt und dort auf dem Becherboden 12 vorwiegend radial nach aussen geführt. Über eine oder mehrere der in der Becherwand 13 angeordneten Stromleiterbahnen 18 wird der Fusspunkt 19 des Störlichtbogens schliesslich auf den Becherrand 10 geführt. Am Übergang vom Becherboden 12 in die Becherwand 13 fliesst der den Störlichtbogen speisende Strom I (Fig.3) in einem gekrümmt ausgebildeten Abschnitt der Stromleiterbahn 18. Durch diese Krümmung wird das auf den Fusspunkt des Störlichtbogens wirkende Magnetfeld das Speisestroms I verstärkt und dadurch auch eine den Störlichtbogen nach aussen zum Becherrand 10 hin führende elektrodynamische Kraft. In den überwiegend im Umfangsrichtung geführten äusseren Abschnitten der Strombahnen 18 ist das Magnetfeld des Speisestroms I am Ort des Lichtbogenfusspunktes radial nach aussen gerichtet und wirkt so auf den Störlichtbogen eine in Umfangsrichtung gerichtete elektrodynamische Kraft, welche dessen Rotation bis zu dessen Erlöschen im Stromnulldurchgang veranlasst.
