Description

Die Erfindung betrifft eine Isolatorenkette mit Ölisolatoren.The invention relates to an insulator chain with oil insulators.

Bei solchen Ölisolatoren schützen die Ölbäder gegen Überschläge, wie sie durch leitende Ablagerungen infolge salziger Niederschläge oder infolge von Gasen, die leitende Teilchen mit sich führen, entstehen können; die Ölbäder bilden eine wirksame Überschlagsstrecke längs der Öloberfläche. In such oil insulators, the oil baths protect against flashovers, such as those caused by conductive ones Deposits as a result of salty precipitation or as a result of gases that are conductive Carry particles with them, can arise; the oil baths form an effective flashover path along the oil surface.

Die Spannungsverteilung längs der Isolatorenketten von Hochspannungsleitungen, insbesondere solchen über 50 000 Volt, wird durch die Ölbäder beeinflußt, weil metallische Schutzkappen vorhanden sind, die große Kapazitäten der Einzelelemente gegen Erde erzeugen. Bekanntlich ist diese Verteilung eine Funktion des von der Kapazität eines Elementes mit Bezug auf Erde und seiner eigenen Kapazität gebildeten Quotienten.The stress distribution along the insulator chains of high-voltage lines, in particular those above 50,000 volts are affected by the oil baths because they are metallic Protective caps are available, the large capacities of the individual elements against earth produce. As is known, this distribution is a function of the capacity of one Element with reference to earth and its own capacity.

Die bekannten Ölisolatoren sind in dieser Beziehung ungünstig; sie weisen eine geringe Eigenkapazität auf, entweder infolge der geringen Oberfläche der Eisenteile und der Kappen, die ihre Pole bilden, wie bei den Hewlettisolatoren, Oder infolge der verhältnismäßig großen Entfernung zwischen den Polen, wie bei den Motorisolatoren.The well-known oil insulators are in this one Relationship unfavorable; they have a low self-capacitance, either as a result of the low Surface of the iron parts and the caps that form their poles, as in the Hewlett insulators, Or because of the relatively great distance between the poles, like with the motor insulators.

Gemäß der Erfindung werden als Elemente der Isolatorenkette Isolatoren der Kappenbolzenbauart in auf den Kopf gestellter Anordnung benutzt; die aus Isolierstoff bestehende Glocke dient als Ölbehälter. Die Eigenkapazität eines solchen Isolators ist verhältnismäßig groß, weil die Eisenteile nicht nur sehr gedrängt aneinanderliegen, sondern auch große Oberfläche haben. Durch die große Eigenkapazität im Verhältnis zur Kapazität gegen Erde wird eine günstige Spannungsverteilung bewirkt. Außerdem hat dieser Isolator den Vorteil, ein Gefäß aus Isolierstoff zu besitzen, und den weiteren Vorteil, daß er billig ist, weil er keines zusätzlichen Organs zur Bildung des Gefäßes bedarf; According to the invention, insulators of the cap bolt type are used as elements of the insulator chain used in an upside-down arrangement; the one made of insulating material Bell serves as an oil container. The self-capacitance of such an isolator is proportionate great because the iron parts are not only very tightly packed, but also also have a large surface. Due to the large internal capacity in relation to the capacity a favorable voltage distribution is achieved with respect to earth. This insulator also has the advantage of being a vessel made of insulating material and the further advantage that it is cheap because it does not have any additional Organ needed to form the vessel;

In der Zeichnung ist ein Ausführungsbeispiel eines Ölisolators nach der Erfindung teils in Ansicht, teils im Schnitt dargestellt.In the drawing is an embodiment of an oil insulator according to the invention partly in view, partly shown in section.

Die Kappe dieses Isolators ist mit 1, der Bolzen mit 2, die Glocke mit 3 bezeichnet. Die Glocke ist so tief ausgebildet, daß sie auch im ungünstigsten Falle öl in einer gewissen Mindesthöhe aufnimmt. Eine Haube 4 bekannter Art schützt den Inhalt des Gefäßes gegen den Witterungseinfluß.The cap of this insulator is designated with 1, the bolt with 2, the bell with 3. The bell is so deep that, even in the worst case, it will contain oil in a certain amount Minimum height absorbs. A hood 4 of known type protects the contents of the vessel against the influence of the weather.
