PATENTAMT.PATENT OFFICE.
Es sind Blitzableiter bekannt, die hornförmig gebogene Elektroden besitzen, so daß ein enger Spalt an zwei entsprechenden Elektroden auftritt, welcher sich mehr und mehr erweitert. Tritt infolge einer statischen Ladung eine Entladung an der engen Stelle auf, so wandert der Lichtbogen zu den entfernteren Enden und reißt dort ab. Die Lichtbogen bleiben dabei öfter so lange bestehen, daß erhebliche statische Ladungen auftreten, welche die Isolation des Stromkreises zerstören.There are lightning rods known which have horn-shaped bent electrodes so that there is a narrow gap at two corresponding electrodes, which becomes more and more expanded. When a discharge occurs in the narrow space due to static electricity on, the arc moves to the more distant ends and breaks off there. The arcs often persist as long as that considerable static charges occur, which the isolation of the circuit destroy.
Um die Dauer des Lichtbogens zu beschränken, soll nach vorliegender Erfindung Widerstand hinter den Lichtbogen eingeführt werden, und zwar in der Weise, daß die Teile, an denen die Entladung zuerst auftritt, aus Material geringen Widerstandes hergestellt werden, während die divergierenden Ansätze aus Material höheren Widerstandes bestehen. Wenn also ein Lichtbogen auftritt und sich den divergierenden Enden zuwendet, so nimmt der Widerstand der Hörner stetig zu und beschleunigt dadurch das Abreißen des Lichtbogens.In order to limit the duration of the arc, according to the present invention Resistance can be introduced behind the arc in such a way that the Parts where the discharge occurs first, made of low resistance material are made, while the divergent approaches made of material of higher resistance exist. So when an arc occurs and turns towards the diverging ends, the resistance decreases Horns steadily closing and thereby accelerating the breaking of the arc.
Die Zeichnung stellt den Erfindungsgegenstand schematisch dar.The drawing represents the subject matter of the invention schematically.
Die Wechselstromquelle 3 speist die zu schützenden Leitungen 1 und 2. Eine Erdabzweigung 4 führt über den Blitzableiter zu der Erdverbindung 6. Der Blitzableiter besteht aus den gekrümmten Stücken 18, 20 und 19, 21. An die kurvenförmigen Stücke 20 und 21 niederen Widerstandes schließen solche höheren Widerstandes 18, 19 an. Beim Aufwärtswandern des Lichtbogens nimmt der Widerstand allmählich zu.The alternating current source 3 feeds the lines 1 and 2 to be protected. An earth branch 4 leads to earth connection 6 via the lightning rod. The lightning rod is in place from the curved pieces 18, 20 and 19, 21. To the curved pieces 20 and 21 of lower resistance connect such higher resistance 18, 19. When hiking upwards of the arc, the resistance increases gradually.
