Description

Isoliergasgefüllte gekapselte elektrische Hochspannungsleitung Die Erfindung bezieht sich auf 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.Insulating gas-filled encapsulated electrical high-voltage line Die The invention relates to an insulating gas-filled, encapsulated electrical high-voltage line, in which the conductor is within a grounded tubular enclosure by means of Post insulators is held, and in which the encapsulation in sections with expansion joints is divided.

Bei gasdichten Kapselungen für als Sammelschienen benutzte Hochspannungsleitungen sind für den Dehnungsausgleich zwischen den einzelnen Kapselungsabschnitten Dehnungsausgleicher bekannt, welche als Faltenbälge ausgebildet sind (DT-AS 1 515 367).For gas-tight enclosures for high-voltage lines used as busbars are expansion compensators for expansion compensation between the individual encapsulation sections known, which are designed as bellows (DT-AS 1 515 367).

Diese Ausführung ist aber vorallem wegen der grossen, dem Kapselungsdurchmesser im Durchmesser etwa entsprechenden Fal tenbälge verhältnismässig teuer und kompliziert. Ausserdem ist der Ausdehnungshub derartiger FaltenDSlge relativ klein, wenn sie für einen höheren Gasinnendruck bemessen si l'id Die Erfindung hat sich zur Aufgabe gestellt, einen De?nnungs ausgleicher anzugeben, mit welchem bei verhältnismässig geringem Aufwand eine relativ grosse Dilatation erreicht wird, so dass im Zuge einer langen Hochspannungsleitung an der Anzahl der benötigten Dehnungsausgleicher eine erhebliche Reduktion vorgenommen werden kann. Erfindungsgemäss wird dies dadurch erreicht, dass als Dehnungsausgleicher Gehäuse vorgesehen sind, in welchen jeweils mindestens ein Kapselungsabschnitt gleitend geführt ist, wobei die Abdichtung zwischen Gehäuse und Kapselungsabschnitt mittels Rollschlauchmembrane 4erfolgt.This version is mainly because of the large, the encapsulation diameter in diameter approximately corresponding Fal tenbälge relatively expensive and complicated. In addition, the expansion stroke of such folds is relatively small when they si l'id dimensioned for a higher internal gas pressure The invention has set itself the task of specifying a deformation compensator with which at relatively large dilation is achieved with relatively little effort, so that in the course of a long high-voltage line to the number of expansion compensators required a considerable reduction can be made. According to the invention, this is thereby achieved achieved that housings are provided as expansion compensators, in each of which at least one encapsulation section is slidably guided, the seal between The housing and the encapsulation section are made by means of a roller tube membrane 4.

Die Zeichnung gibt ein Ausführungsbeispiel der Erfind-wing wieder, anhand dessen diese näher erläutert wird.The drawing shows an embodiment of the invention wing, based on which this is explained in more detail.

Im Inneren der beiden Kapselungsabschnitte, welche ,jr Rohre l, 2. ausgebildet sind, ist der Leiter 5, 6 mit Hilfe der Stützisolatoren 8 gehaltert. In den Isolatoren 8 könnten die Teile 5, 6 des Leiters gleiten. An den einander zugekehrten Enden der rohrförmigen Abschnitte 1, 2 der Kapselung tragen letztere Rohrstücke 3, 4, in denen die Isolatoren 8 eingesetzt sind. Letztere werden durch angeschraubte Ringe 3a, 4a fixiert.Inside the two encapsulation sections, which, jr tubes l, 2. are formed, the conductor 5, 6 is supported with the aid of the post insulators 8. In the insulators 8, the parts 5, 6 of the conductor could slide. To each other facing ends of the tubular sections 1, 2 of the encapsulation carry the latter Pipe sections 3, 4 in which the insulators 8 are used. The latter are through screwed on rings 3a, 4a fixed.

Die Rohrstücke 3, 4 sind in den Ansatzstücken 9a des Gehäu@es 9 gleitend geführt, wobei die Ansatzstücke 9a mit dem Gehäuse flanschartig verschraubt sindX Als AhdichFung zwischen den relativ zueinander bewegbaren Teilen 9a und 3 bzw. 4 ist die Rollschlauchmembrane 10 vorgesehen, welche sich im Spaltraum zwischen den Teilen 9a und 3 bzw. 4 abrollen kann, wenn eine Relativbewegung stattfindet. Die Rollschlauchmembrane 10 ist zwischen den Teilen 3, 3a bzw. 4, 4a einerseits und zwischen 9, 9a andererseits gasdicht eingespannt. Das Gehäuse 9 ist durch den Deckel 9b verschlossen, welche eine verschliessbare Einfüllöffnung 11 für das Isoliergas besitzt. Als Isoliergas wird mit Vorteil SF6 von z.B. 4 ata verwendet, welches die Räume zwischen dem Leiter 5, 6 und den Teilen 1, 2, 3, 4, 9 ausfüllt.The pipe sections 3, 4 slide in the extension pieces 9 a of the housing 9 out, wherein the extension pieces 9a are screwed to the housing in a flange-like mannerX As an attachment between the relatively movable parts 9a and 3 or 4, the roller hose membrane 10 is provided, which is located in the gap can roll between the parts 9a and 3 or 4 when a relative movement takes place. The roller hose membrane 10 is between the parts 3, 3a and 4, 4a on the one hand and clamped between 9, 9a, on the other hand, in a gas-tight manner. The housing 9 is through the Cover 9b closed, which has a closable filler opening 11 for the insulating gas owns. SF6 of e.g. 4 ata is advantageously used as the insulating gas, which the Fills in spaces between conductor 5, 6 and parts 1, 2, 3, 4, 9.

Zur Begrenzung der Längsverschiebung sind an den Teilen 3, 4 flanschartige Anschlagstücke 12 angebracht, welche dadurch eine Begrenzung bewirken, dass sie an den Teilen 9a bzw .- an den Muttern 14 am Ende der Stehbolzen 13 zum Anschlag kommen.To limit the longitudinal displacement, the parts 3, 4 are flange-like Stop pieces 12 attached, which thereby cause a limitation that they on the parts 9a or - on the nuts 14 at the end of the stud bolts 13 to the stop come.

Die-Leiterstücke 5, 6 besitzen eigene, von den Dehnungsausgleichen der Kapselung unabhängige Ausdehnungsglieder. An den einander zugekehrten Enden der Leiterstücke 5, 6 sind jeweils übereinandergreifende Rohrteile 5a, 6a angebracht, welche im Inneren das flexible Stromverbindungsband 7 aufnehmen. Es ist nicht notwendig, dass im Zuge einer längeren Hochspannungsleitung die gleiche Anzahl von Ausdehnungsgliedern des Leiters und denjenigen der Kapselung vorgesehen werden.The ladder sections 5, 6 have their own expansion compensations expansion members independent of the encapsulation. At the ends facing each other of the ladder sections 5, 6 overlapping tube parts 5a, 6a are attached, which receive the flexible power connection tape 7 inside. It's not necessary, that in the course of a longer high-voltage line the same number of expansion members of the conductor and those of the encapsulation are provided.
