Abstract
Description
Die Erfindung betrifft einen Prüfendverschluß für ein supraleitendes Kabel nach dem Oberbegriff des Anspruchs 1.The invention relates to a test termination for a superconducting Cable according to the preamble of claim 1.
Es ist bekannt, daß elektrische Kabel für die Übertragung großer Leistungen häufig auf ihre Funktionstüchtigkeit bzw. Betriebssicherheit sowie auf technische Parameter überprüft werden müssen.It is known that electrical Cable for the transfer greater Services often on their functionality or operational safety as well as technical parameters have to.
Zur Prüfung derartiger Kabel werden in der Regel fertig montierte Endverschlüsse mit integriertem Feldsteuerkegel verwendet, die schnell montiert werden können. Meist befindet sich der integrierte Feldsteuerkegel an der Außenseite eines im Endverschluß eingebauten Rohres.To test such cables usually fully assembled terminations with integrated field control cone used that can be assembled quickly. Mostly there is the Integrated field control cone on the outside of a built-in end closure Tube.
Derartige Prüfendverschlüsse sind zum Prüfen von papierisolierten Hochspannungskabeln, wie Öl- Masse- und Gasdruckkabel sowie als Wasserendverschlüsse von VPE-Kabeln geeignet.Such test terminations are for testing paper-insulated high-voltage cables, such as oil, ground and gas pressure cables as well as water terminations suitable from XLPE cables.
Supraleiterkabel bestehen aus einer
Kabelseele mit einem oder mehreren Leitern aus supraleitfähigem Material
sowie einer Isolierschicht und einem die Kabelseele umgebenden Kryostaten.
Aus der
Für diese Art von Kabeln sind die bislang bekannten Prüfendverschlüsse nicht anwendbar, da keine Vorkehrungen für den Transport des Kühl- und Imprägniermittels vorgesehen sind.For this type of cable is not the previously known test termination Applicable since there are no provisions for the transport of the coolant and impregnating agent are provided.
Der Erfindung liegt von daher die Aufgabe zugrunde, einen Prüfendverschluß für ein supraleitendes Kabel bereitzustellen, der eine schnelle Montage ermöglicht und eine sowohl thermische als auch elektrische Isolierung darstellt.The invention is therefore the Task based, a test termination for a superconducting To provide cables that enable quick assembly and represents both thermal and electrical insulation.
Diese Aufgabe wird durch die im Kennzeichen des Anspruchs 1 erfaßten Merkmale gelöst.This task is performed by the in the indicator of claim 1 recorded Features solved.
Weitere vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen erfaßt.Further advantageous configurations the invention are covered in the subclaims.
Gegenüber den im fertigen Kabelsystem zum Einsatz kommenden Endverschlüssen, wird der Prüfendverschluß gemäß der Lehre der Erfindung zum einen höhere thermische Verluste verursachen und bietet zum anderen keine Möglichkeit eines hohen Prüfstromes. Beides ist jedoch für die dielektrische Prüfung irrelevant.Compared to that in the finished cable system Coming terminations, the test end closure becomes according to the teaching the invention on the one hand higher cause thermal losses and on the other hand offers no possibility a high test current. However, both are for the dielectric test irrelevant.
Die Erfindung ist anhand des in der Figur schematisch dargestellten Ausführungsbeispiels näher erläutert.The invention is based on the Figure illustrated schematically illustrated embodiment.
