Description

In der Patentschrift 291324 ist eine Einrichtung mit scharfen Kanten beschrieben, bei welcher Körper verschiedener Polarität durch zwischengeschaltete Isolierkörper hoher Dielektrizitätskonstante getrennt sind.In the patent 291324 a device with sharp edges is described at which body of different polarity through interposed insulating bodies of high dielectric constant are separated.

Im Zusatzpatent 306732 ist diese Anordnung in der Form eines Apparates dargestellt, zwischen dessen beiden Elektroden eine Isolierglocke angeordnet ist.In the additional patent 306732 this arrangement is shown in the form of an apparatus, an insulating bell is arranged between the two electrodes.

ίο Eine Erweiterung und Verbesserung der beschriebenen Anordnungen bildet den Gegenstand der vorliegenden Erfindung.ίο An expansion and improvement of the arrangements described forms the subject of the present invention.

Es ist nämlich bei den bisher beschriebenen Anordnungen, wenn man sie für sehr hohe Spannungen verwendet, nicht ganz leicht, die Konstruktionen so zu bemessen, daß ein hinreichender Abstand zwischen den Elektroden um die Kante der Isolierglocke herum gewahrt bleibt. Man muß auch dabei berücksichtigen, daß bei der Wirkung des Apparates , eine Glimmlichtbildung eintritt, Avelche mehr oder weniger große Flächen der Isolierglocke leitend überzieht, so daß die Kriechwege für einen etwaigen Überschlag dadurch verkleinert werden.It is in fact with the arrangements described so far, if they are used for very high Tensions used, it is not very easy to dimension the constructions in such a way that a sufficient Distance between the electrodes around the edge of the insulating bell is maintained. One must also take into account that with the action of the apparatus a glowing light occurs, Avelche more or less large areas of the insulating bell coated conductive so that the creepage distances for any rollover can thereby be reduced.

Nach der vorliegenden Erfindung wird nun dieser Übelstand dadurch beseitigt, daß mehrere derartiger Isolierglocken elektrisch hintereinander geschaltet sind.According to the present invention, this drawback is now eliminated in that several such insulating bells are electrically connected in series.

Ein Ausführungsbeispiel ist in der Zeichnung schematisch dargestellt.An exemplary embodiment is shown schematically in the drawing.

L ist die Hochspannung führende Leitung, welche mit der einen Elektrode, einem Rechen R1, verbunden ist. Die andere Elektrode, ebenfalls ein Rechen -R2, dessen Zähne senkrecht zu den Zähnen des ersten Rechens stehen, ist mit der Erde E verbunden. Zwischen den beiden Elektroden sind nun zwei Isolierglocken G1 und G2 angeordnet, welche zweckmäßig aus Glas bestehen und weiche eine wesentliche Vergrößerung des Überschlagsweges bewirken. L is the high-voltage line which is connected to one electrode, a rake R 1 . The other electrode, also a rake -R 2 , the teeth of which are perpendicular to the teeth of the first rake, is connected to earth E. Two insulating bells G 1 and G 2 are now arranged between the two electrodes, which are expediently made of glass and which cause a substantial increase in the rollover path.
