Description
In Schaltanlagen sollen Leitungsführungen mit kleinem Krümmungsradius möglichst vermieden und die Leitungen in großen Bögen geführt werden, um Überschläge infolge Wanderwellenreflektion an der Induktivität derartiger Winkelpunkte zu vermeiden. Es wird jedoch nicht beachtet, daß die Ölschalter sehr gefährliche Stromschleifen bilden, woraus sich der häufige Überschlag von 01-Schalterdurchführungen ergibt.In switchgear, wiring should be as small as possible avoided and the lines are led in large bends, as a result of flashovers To avoid traveling wave reflection at the inductance of such angular points. It however, it is not taken into account that the oil switches form very dangerous current loops, from which the frequent rollover of 01 switch bushings results.
Abb. ι erläutert diesen Vorgang näher. Um die scharfe Leitungskrümmung y zu vermeiden, wird die Leitung in sanftem Bogen χ geführt. Der Ölschalter α bildet aber infolge seiner Schleife, die durch die Durchführung h und d und die Traverse c gebildet ist, eine gefährliche Stromschleife, so daß Überschläge längs der Linie e häufig sind. Nachstehend beschriebene Erfindung vermeidet diese Überschläge dadurch, daß der Überspannung ein bequemerer Weg geboten wird. In Abb. 2 ist eine derartige Anordnung skizziert. Zwischen den beiden Durchführungen derselben Phase befindet sich eine Kugelfunkenstrecke mit den Elektroden f und g·, deren Überschlagswert tiefer liegt als die Überschlagsspannung der Isolatoren.Fig. Ι explains this process in more detail. In order to avoid the sharp bend y in the line, the line is routed in a gentle curve χ. The oil switch α forms a dangerous current loop due to its loop, which is formed by the implementation h and d and the cross member c , so that flashovers along the line e are frequent. The invention described below avoids these flashovers by offering the overvoltage a more convenient route. Such an arrangement is sketched in Fig. 2. Between the two bushings of the same phase there is a spherical spark gap with the electrodes f and g ·, the flashover value of which is lower than the flashover voltage of the insulators.
Tritt nun eine Überspannungswelle auf, so durchschlägt sie diese Funkenstrecke, da dieser Weg weniger Widerstand bietet als die Ölschalterschleüe, und umgeht somit den Ölschalter. Zur Unterstützung dieser Wirkung ist es zweckmäßig, die Zu- und Ableitung in einem Bogen h und i oder horizontal, k und I, an den Ölschalter heranzuführen. Ein Lichtbogen kann zwischen den beiden Elektroden f und g nicht bestehen bleiben, da sie in eingeschaltetem Zustand des Ölschalters gleiches Potential besitzen. Im ausgeschalteten Zustand des ölschalters kann die Funkenstrecke durch Verschieben einer der Elektroden vergrößert werden.If an overvoltage wave now occurs, it breaks through this spark gap, as this path offers less resistance than the oil switch loop, and thus bypasses the oil switch. To support this effect, it is advisable to lead the supply and discharge lines in an arc h and i or horizontally, k and I, to the oil switch. An arc cannot remain between the two electrodes f and g because they have the same potential when the oil switch is switched on. When the oil switch is switched off, the spark gap can be increased by moving one of the electrodes.
