Es ist bekannt, elektrische Leitungen in geschlossenen Rohren zu verlegen, die zur Beherrschung höherer Spannungen mit Druckgas gefüllt· sind. Es ergibt sich hierdurch ein verhältnismäßig kleiner Durchmesser der Rohre. Anderseits entstehen aber Schwierigkeiten hinsichtlich der Abstützung des elektrischen Leiters, da bei einer vorzugsweise zu diesem Zweck vorgesehenen Isolationsscheibe die in radialer Richtung zur Verfügung stehende Strecke nicht mehr als Kriechweg ausreicht. Außerdem hat man von einer derartigen Ausführungsform biisher auch deshalb keinen Gebrauch gemacht, weil man für eine in das Rohr hineingestellte Abstützscheibe keine einwandfreie Lösung der bei Druckgasisolierung besonders sorgfältig auszuführenden dielektrischen Verlötung des Isoliermaterials mit dem Rohr wußte. Man hat sich daher in derartigen Fällen veranlaßt gesehen, die Abstützteile zur Erzielung langer Kriechwege mit unter einem Winkel zur Rohrachse stehenden Flächen auszuführen, welche somit auch schräg zu den elekirischen Kraftlinien stehen und eine Brechung derselben hervorrufen. Infolgedessen ergibt sich bei dieser bekannten Anordnung, insbesondere unter der Wirkung elektrischer Stoßspannungen, eine Neigung zur Gleitfunkenbildung. It is known to lay electrical lines in closed pipes that are used for Control of higher voltages are filled with compressed gas. It arises from this a relatively small diameter of the tubes. On the other hand, however, difficulties arise with regard to the support of the electrical conductor, since an insulating disk is preferably provided for this purpose the distance available in the radial direction is no longer sufficient as a creepage distance. Besides, one has no use has been made of such an embodiment so far because there is no perfect solution for a support disc placed in the pipe In the case of compressed gas insulation, dielectric soldering of the Insulating material with the pipe. One has therefore acted in such cases seen, the support parts to achieve long creepage distances with at an angle to execute surfaces standing to the pipe axis, which are thus also oblique to the electrical Lines of force stand and cause a breaking of them. As a result, results in this known arrangement, in particular under the effect of electrical Impulse voltages, a tendency to form sliding sparks. Dieser Nachteil wird vermieden und zugleich eine einwandfreie dielektrische Verlötung zwischen Isolator und Druckgasrohr erzielt, indem erfindungsgemäß die senkrecht zur Rohrleitung stehenden, aus Isolationsplatten bestehenden Abstützteile zwischen der Verschraubungsstelle zweier aneinanderstoßender Flansche eingespannt sind, welche mit großen Abrundungen von der Verschraubung^- stelle in den zylindrischen Teil der Druckgasrohre übergehen.This disadvantage is avoided and, at the same time, proper dielectric soldering is avoided Achieved between the insulator and the compressed gas pipe by, according to the invention, the perpendicular to the pipeline, made of insulation plates existing support parts between the screwing point of two abutting Flanges are clamped, which with large roundings from the screw connection ^ - place in the cylindrical part of the compressed gas pipes. Es ist zwar in der Fernsprech- bzw. Fernschreibetechnik zur Hochfrequenzübertragumg bekannt, in einer ölgefüllten Rohrleitung eine von einem Durchführungsisolator gehaltene elektrische Leitung durch Platten abzustützen, welche zwischen den mit guten Abrundungen ausgeführten Flanschen zweier aneinanderstoßender Rohre eingespannt sind. Jedoch handelt es sich bei dieser Anordnung nicht um die Lösung eines Hochspannungsproblems, so daß bezüglich der Abrundungen und der Verbindung der Abstützteile mit den Flanschen das elektrische Feld keine Rolle spielen kann.Although it is used in telephone or telex technology for high-frequency transmission known, one held by a bushing insulator in an oil-filled pipeline electrical line to be supported by plates, which are well rounded between the two Executed flanges of two abutting pipes are clamped. However this arrangement is not a solution to a high-voltage problem, so that with respect to the roundings and the connection of the support parts with the flanges the electric field cannot play a role. In der Abbildung ist ein Ausführungsbeispiel der Erfindung dargestellt. Es ist 1 ein metallischer Leiter, 2 das ihn umgebende druckfeste Rohr, welches an beiden Enden mit großen Abrundungen 3 in die eigentlichen Flanschteile 4 übergeht. Zwei aneinanderstoßende Rohre sind unter Zwischenlegung der Isolationsscheibe 5 an der FlanschsteUe miteinander verschraubt. Die Isolationsschesibe 5, welche aus möglichst homogenem, jedenfalls in Achsrichtung nicht geschichtetem Material, vorzugsweise aus Gummi, besteht, besitzt in der Mitte eine Bohrung 6, durch welche der Leiter 1 hindurchgesteckt ist. Um den Leiter ist die Isolationsscheibe 5 zur Vergrößerung des Kriechweges bei 6 nabenartig ausgebildet.In the figure, an embodiment of the invention is shown. It's 1 a metallic conductor, 2 the pressure-resistant pipe surrounding it, which at both ends merges into the actual flange parts 4 with large roundings 3. Two butting against each other Pipes are with the interposition of the insulating disk 5 on the flange with each other screwed. The insulation washer 5, which is as homogeneous as possible, in any case in the axial direction is not layered material, preferably made of rubber, has in in the middle a hole 6 through which the conductor 1 is inserted. To the head the insulating disk 5 is designed like a hub to increase the creepage distance at 6.
