Description

Durchführungsisolator mit Glimmringen für hohe Spannungen. Versieht man einen Durchführungsisolator mit einem .Beleg, der gegen den Bolzen sowohl als auch gegen die Fassung isoliert ist, so nimmt dieser infolge seiner Kapazität eine Spannung gegen Bolzen. und Fassung an, die in einem bestimmten Verhältnis zu der an. dem Bolzen herrschenden Spannung steht. Diese Spannung kann. dazu dienstbar gemacht werden, die Gesamtspannung zu messen oder in Abhängigkeit von dieser Spannung eine Auslösevorrichtung zu betätigen.Bushing insulator with glow rings for high voltages. Provides a bushing insulator with a .Beleg, which against the bolt as well as is also insulated from the socket, this takes a due to its capacity Tension against bolt. and version, which is in a certain proportion to the at. the bolt is under tension. This tension can. subservient to this can be made to measure the total voltage or as a function of this voltage to operate a release device.

Gemäß der vorliegenden Erfindung sollen zu .diesem Zwecke die an sich bekannten Glimmringe benutzt werden. Um die Messung zu ermöglichen, werden dieselben von der Fassung isoliert, und es wird zwisdh-tn beiden Teilen ein Meßinstrmnentoder ein Relais entweder direkt oder unter Zwischenschaltung eines Meßtransformators angeschlossen. Dieser Transformator braucht nur für .einen kleinen Teil der Gesamtspannung bemessen zu sein, so daß man die sonst zur Spannungsmessung benötigten Spamnungswandler, die die Gesamtspannung auszuhalten haben, erspart.According to the present invention to .this Purposes the known glow rings are used. To enable the measurement, they are isolated from the socket, and there is one between the two parts Measuring instrument or a relay either directly or with the interposition of a Measuring transformer connected. This transformer only needs for a small one Part of the total voltage to be measured so that you can otherwise measure the voltage required spam strain converters, which have to withstand the total voltage, saved.

Durch die Eim;richtung nach der Erfindung kann man die zwischen dem Durchführungsbolzen einer Phase und Erde herrschende Spannung kontrolUeren, man kann aber die Instrumente auch zwischen den igalierten Glimmringen zweier Durchflihrungen, die in verschiedenen Phasen liegen, anordnen und so die zwischen diesen Phasen bestehende Spannung messen.By the Eim; direction according to the invention, one can determine between the Check the voltage that is prevailing in a phase and earth, man but the instruments can also be placed between the sealed glow rings of two passages, that are in different phases, and so the existing between these phases Measure the voltage.

In den. Abbildungen sind vezschi.edene Ausführungsbeispiele der Erfindung dargestellt. a bezeichnet den, Hochspannung führenden Durchführungsbolzen, b den Zylinder ;aus Isoliermaterial,, c den ggeeerdeben Konstruktionsteil, an dem die Durchführung vermittels der Fassung d befestigt ist, e die Glimmringe.In the. Illustrations are shown various exemplary embodiments of the invention. a denotes the high-voltage lead-through bolt, b the cylinder, made of insulating material, c the ground-level structural part to which the lead-through is attached by means of the socket d, e the glow rings.

Abb. i zeigt eine Anordnung zur Messung der zwischen dem Durchführungsbolzens und Erde herrschenden Spannung. Zwischen den gegen Erde isolierten und miteinander verbundenen Glimmringen e deinerseits und der Fassung d anderseits liegt der Transformator f, an dessen Selzundärwicklung ein Meßinstrument g angeschlossen ist. In der Anordnung nach Abb:. z wird die Spannung zwischen den beiden Leitern a, a1 gemessen.Fig. I shows an arrangement for measuring the voltage between the bushing bolt and earth. The transformer f, to the secondary winding of which a measuring instrument g is connected, is located between the glow rings e, which are isolated from earth and connected to one another, and the socket d on the other hand. In the arrangement according to Fig. z the voltage between the two conductors a, a1 is measured.
