Isoliergasgefüllte, gekapselte elektrische Hochspannungsleitung. Insulating gas-filled, encapsulated electrical high-voltage line.
Die Neuerung betrifft eine isoliergasgefüllte gekapselte elektrische Hochspannungsleitung, bei welcher der Leiter innerhalb einer geerdeten rohrförmigen Kapselung mittels Stützisolatoren gehaltert ist., und bei welcher die Kapselung in Abschnitte mit Dehnungsausgleichern unterteilt ist, welche Gehäuse enthalten, in denen jeweils mindestens ein Kapselungsäbschnitt gleitend geführt ist, wobei die Abdichtung zwischen Gehäuse und Kapselungsabschnitt mittels Rollschlauchmeir.brane erfolgt.The innovation concerns an encapsulated one filled with insulating gas electrical high-voltage line, in which the conductor is inside a grounded tubular enclosure by means of Post insulators is supported., And in which the encapsulation is divided into sections with expansion compensators, which Housing included, in each of which at least one capsule section Is slidably guided, the seal between the housing and the encapsulation section by means of Rollschlauchmeir.brane he follows.
Won η derartige Hochspannungsleitungen vor der Inbetriebnahme mit dem Isolierdruckgas, z.B. SFg, gefüllt werden, so ist vor dein Füllen eine Evakuierung der Kapselung erforderlich, umWon η such high-voltage lines before commissioning be filled with the insulating compressed gas, e.g. SFg, then this is the case your filling required an evacuation of the enclosure
die Feuchtigkeit zu entfernen. Durch das Evakuieren besteht die Gefahr einer Umstülpung der Rollschlauchmembrane innerhalb des Zylinuerspaltraumes, in dem sie untergebracht ist. Bei der darauf folgenden Füllung rr.it dem Isolierdruckgas kann es dann zu einer unerwünschten Faltenbildung der Rollschlauchmembrane kommen, durch welche das ordnungsgemässe Funktionierer, unter Umständen beeinträchtigt wird.to remove the moisture. When evacuating, there is a risk of the roller hose membrane turning inside out of the cylinder gap in which it is housed. The subsequent filling rr.with the insulating compressed gas can then lead to undesirable wrinkling of the roller tube membrane come through which the proper functioning, may be affected.
Der Neuerung liegt die Aufgabe zu Grunde, derartige Verkommnisse zu verhindern. Neuerungägemäss wird deshalb vorgeschlagen, dass eine von aussen betätigbare Stützvorrichtung vorgesehen ist, welche in den von der- Rollsehlauehiüembrane gebildeten Zwischenraum für deren Abstützung einbringbar ist.The innovation is based on the task of such incidents to prevent. According to the innovation, it is therefore proposed that that an externally operable support device is provided, which is located in the von der Rollsehlauehiüembrane formed space for their support can be introduced.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung.The drawing shows an embodiment of the invention.

Im Inneren der beiden Kapselungsabschnitte, Vielehe als Rohre 1,2 ausgebildet sind, ist der Leiter 5,6 mit Hilfe der Stützisolatoren 8 gehaltert, wobei die Leiter in den Isolatoren gleiten können. Die Kapselungsabschnitte 1,2 gehen in RohrstückeInside the two encapsulation sections, polygamy as tubes 1.2 are formed, the conductor is 5.6 with the help of the post insulators 8 supported, the conductors can slide in the insulators. The encapsulation sections 1, 2 go in pipe sections

3,4 über, in welchen die Isolatoren 8 durch Ringe 3a, 4a fixiert sind. Die Rohrstücke 3, 4 gleiten in Ansatzstücken 9a des Gehäuses 9. Als Abdichtung zwischen den relativ zueinander bewegbaren Teilen 9a und 3 bzw. 4 ist die Rollschlauchmembrane 10 vorgesehen, die sich im Spaltraun zwischen den Teiler. 9a und 3 bzw. 4 abrollen kann. Die Rollschlauchmembrane 10 ist zwischen den Teilen 3, 3a bzw. 4, 4a einerseits und zwischen 9, 9a andererseits gasdicht eingespannt. Das Gehäuse S ist durch den Deckel 9b verschlossen, welcher eine verschliessbare Ocffnung 11 besitzt, die dem Evakuieren und dem Füllen mit Isolierdruckgas, z.B. SF_ von 4 ata, dient, das3.4 over, in which the insulators 8 by rings 3a, 4a are fixed. The pipe sections 3, 4 slide in extension pieces 9a of the housing 9. As a seal between the relative to each other movable parts 9a and 3 or 4, the roller hose membrane 10 is provided, which is in the gap between the dividers. 9a and 3 or 4 can roll. The roller hose membrane 10 is between the parts 3, 3a and 4, 4a on the one hand and between 9, 9a on the other hand clamped gas-tight. The housing S is closed by the cover 9b, which is a lockable Has opening 11, which is used for evacuating and filling with insulating compressed gas, e.g. SF_ of 4 ata, which
in Betriebszustand die Räume zwischen dem Leiter 5,6 und den Teilen 1, 2, 3, 4, 9 ausfüllt. Zur Begrenzung der Längsverschiebung tragen die Teile 3,4 flanschartige Anschlagstücke 12, welche an den Teilen 9a bzw. an den Muttern 14 am Ende der Stehbolzen 13 zum Anschlag kommen. In den rohrförmigen, übereinandergreifenden Endstücken 5a, 6a der Leiter 5, 6 befindet sich das flexible Stromband 7. In den von der Rollschlauchmembrane 10 freigelassenen ringspaltförmigen Zwischenraum sind während der Evakuierung Rohrstücke 15 einbringbar, um die Rollschlauchmembrane 10 gegen ein Unstülpen unter der Wirkung des äusseren Luftdruckes zu sichern. In Fig. 2 ist diese Stellung gezeigt. Mit Hilfe der Muttern 17 am äusseren Ende der Gewindebolzen 16 kann das über den Arm 15a mit letzteren verbundenen Rohrstück 15 verstellt werden. Die Bolzenin the operating state fills the spaces between the conductor 5, 6 and parts 1, 2, 3, 4, 9. To limit the longitudinal displacement carry the parts 3, 4 flange-like stop pieces 12 which are attached to the parts 9a or to the nuts 14 at the end of the Stud 13 come to the stop. In the tubular, overlapping End pieces 5a, 6a of the conductors 5, 6 are the flexible current tape 7. In the from the roll hose membrane 10 left free annular gap-shaped space can be introduced during the evacuation pipe pieces 15 to to secure the roller hose membrane 10 against being turned inside out under the action of the external air pressure. In Fig. 2 is shown this position. With the help of the nuts 17 at the outer end of the threaded bolts 16 this can be done via the arm 15a the latter connected pipe section 15 can be adjusted. Bolts
