mit hohlrohrförmiger Isolierung Die Erfindung liegt auf dem Gebiet der kühlbaren elektrischen Kabel für die Ubertragung höchster Leistungen und ist bei der konstruktiven Ausgestaltung einer Verbindungsmuffe für ein Kabel mit hohlrohrförmiger Isolierung anzuwenden.with hollow tubular insulation The invention is in the field the coolable electrical cable for the transmission of highest power and is in the structural design of a connecting sleeve for a cable with a hollow tubular Apply insulation.
Zur Übertragung großer elektrischer Leistungen ist bereits ein Kabel vorgeschlagen worden, bei dem der direkt kühlbare Leiter in einem Kunststoffrohr liegt, dessen Hohlquerschnitt mindestens das Dreifache des Leiterquerschnitts beträgt und das innen mit einer abriebfesten Schicht aus einem leitenden Kunststoff beschichtet ist.There is already a cable for transmitting large amounts of electrical power has been proposed in which the directly coolable conductor in a plastic tube whose hollow cross-section is at least three times the conductor cross-section and the inside is coated with an abrasion-resistant layer made of a conductive plastic is.
Bei diesem Kabel können der elektrische Leiter und das die Isolierung bildende Kunststoffrohr getrennt voneinander gefertigt, aufgetrommelt, geliefert und verlegt werden, wobei der Leiter in das Kunststoffrohr eingezogen wird (DE-ANlr P 28 52 104.2). Bei der Errichtung einer Kabel anlage mit einem derartigen Kabel sind die Muffenabstände nur noch von den maximalen Lieferlängen des Isolierrohres bestimmt. Obwohl hier Einzellängen von bis zu 1000 m möglich sind, müssen bei längeren Kabeltrassen Verbindungsmuffen gesetzt werden.With this cable, the electrical conductor and the insulation forming plastic pipe manufactured separately from each other, reeled up, delivered and laid, whereby the conductor is pulled into the plastic pipe (DE-ANlr P 28 52 104.2). When setting up a cable system with such a cable the sleeve spacings are only from the maximum delivery lengths of the insulating pipe certainly. Although individual lengths of up to 1000 m are possible here, longer ones must Cable route connection sleeves are set.
Der Erfindung liegt die Aufgabe zugrunde, eine für das bereits vorgeschlagene Kabel geeignete Verbindungsmuffe zu schaffen.The invention is based on the object of one for the already proposed Cable to create a suitable connection sleeve.
Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, daß die beiden rohrförmigen, mit Abstand zue,nander angeordneten und miteinander zu verbindenden Enden der Kunststoffisolierungen mit einem dünnwandigen, mechanisch stabilen und unmagnetischen Metallrohr unterlegt sind, daß zwischen den Enden der Kunststoffisolierung auf dem Metallrohr eine aus zwei Halbschalen bestehende elektrisch leitende Kunststoffschicht angeordnet ist und daß der übrige Bereich der Verbindungsstelle zwischen den konisch oder treppenförmig abgesetzten Enden der Kunststoffisolierungen mit selbstverschweißenden oder unter Wärmeeinwirkung vernetzenden Isolierbändern ausgewickelt ist.To solve this problem it is provided according to the invention that the two tubular, at a distance from each other arranged and to be connected to each other ends of the plastic insulation with a thin-walled, mechanically stable and non-magnetic metal tube are underlaid that between the Ends of the plastic insulation on the metal tube consisting of two half-shells electrically conductive plastic layer is arranged and that the remaining area the connection point between the conical or stepped ends of plastic insulation with self-amalgamation or under the influence of heat cross-linking insulating tape is unwound.
Durch die Verwendung eines Metallrohres, das innen an den zu verbindenden Enden der Kunststoffisolierungen anliegt, ist gewährleistet, daß überhaupt die Verbindungsstelle montiert werden kann. Die darüber angeordnete elektrisch leitende Schicht und die aus Isolierbändern bestehende Wickelkeule gewährleisten dann, daß die Verbindungsstelle hochspannungsfest ausgebildet ist, und zwar sowohl beim Übergang von der inneren Leitschicht auf die Isolierung als auch im Grenzbereich Kabelisolierung/Muffenwickel.By using a metal pipe that is attached to the inside of the pipe to be connected Ends of the plastic insulation is applied, it is guaranteed that the connection point can be mounted. The electrically conductive layer arranged above and the consisting of insulating tapes winding lobe then ensure that the connection point is designed to withstand high voltages, both at the transition from the inner Conductive layer on the insulation as well as in the border area between cable insulation and sleeve wrapping.
Ein Ausführungsbeispiel der neuen Verbindungsmuffe ist in der Figur dargestellt.An embodiment of the new connecting sleeve is shown in the figure shown.
Die Figur zeigt die Verbindung zweier Hochspannungskabel 1 und 2, in deren hohlrohrförmiger Isolierung 3 der Leiter 4 angeordnet ist. Die hohlrohrförmige Isolierung 3 ist nt einer inneren Leitschicht 3 versehen, mit der der Leiter 4 in Kontakt steht.The figure shows the connection of two high-voltage cables 1 and 2, in the hollow tubular insulation 3 of which the conductor 4 is arranged. The hollow tubular Insulation 3 is provided with an inner conductive layer 3 with which conductor 4 in Contact is available.
Zur Herstellung der Verbindungsmuffe wird zunächst in eines der zu verbindenden Rohrenden ein dünnwandiges, aber mechanisch stabiles und unmagnetisches Metallrohr 6 eingesteckt, das nur ganz schwergängig an der Innenwandung der inneren Leitschicht des jeweiligen Rohres hin- und herzuschieben ist. Danach wird in an sich bekannter Weise die Leiterverbindung 5 hergestellt, beispielsweise durch Hartlöten, durch Schweißen, Pressen oder gar Verschrauben. Nach Herstellung der Leiterverbindung oder auch nach Durchzug eines Einzugseiles zum späteren Einziehen des Leiters wird das Metallrohr 6 in die Mittellage geschoben. Danach werden die im vorliegenden Fall treppenförmig abgesetzten Enden der hohlrohrförmigen Isolierung mit Hilfe von Heizmanschetten auf das Metallrohr 6 aufgetempert. Durch diese Wärmebehandlung erfolgt eine Festlegung der Rohrenden auf dem Metallrohr.To produce the connecting sleeve, one of the to connecting pipe ends a thin-walled, but mechanically stable and non-magnetic Metal tube 6 inserted, which is very difficult to move on the Inner wall the inner conductive layer of the respective pipe is to be pushed back and forth. Thereafter the conductor connection 5 is established in a manner known per se, for example by brazing, welding, pressing or even screwing. After manufacture the ladder connection or after a pull-in rope has been pulled through for later pulling in of the conductor, the metal tube 6 is pushed into the central position. After that, the in the present case, the ends of the hollow tubular insulation that are stepped off Heated onto the metal tube 6 with the aid of heating jackets. Through this heat treatment the pipe ends are fixed on the metal pipe.
Anschließend wird der freie Bereich des Metallrohres 6 mit einem elektrisch schwachleitenden Kunststoffmaterial 7 sauber ausgekleidet, so daß keine Kanten, Vorsprünge oder Spalten im Bereich der 100-%-Äquipotentialfläche entstehen. Hierzu wird ein Material verwendet, dessen Polymerbasis mit dem Polymer der Kunststoffisolierung 3 übereinstimmt. Das Material kann beispielsweise in Form von zwei Halbschalen vorliegen, die genau zwischen die beiden Rohrenden passen.Then the free area of the metal pipe 6 is electrically weakly conductive plastic material 7 neatly lined so that no edges, Projections or gaps arise in the area of the 100% equipotential area. For this a material is used, its polymer base with the polymer of the plastic insulation 3 matches. The material can, for example, be in the form of two half-shells, which fit exactly between the two pipe ends.
Anschließend wird mit Hilfe von isolierenden Bändern auf der Basis eines Äthylen-Propylen-Copolymerisates, die entweder selbst verschweißen oder unter Wärmeeinwirkung miteinander vernetzen, in an sich bekannter Weise der Muffenwickel 8 hergestellt, der die treppenförmig abgesetzten Enden der Kunststoffisolierungen überdeckt.Subsequently, with the help of insulating tapes on the base an ethylene-propylene copolymer, which either weld themselves or under Cross-link the action of heat with one another, in a manner known per se, the sleeve wrap 8 made of the stepped ends of the plastic insulation covered.
Für den Fall einer nachfolgenden Wärmebehandlung wird anschließend die Vulkanisierform angebracht und unter Anwendung von Wärme und Druck der Muffenwickel vernetzt.In the event of a subsequent heat treatment, then the vulcanizing mold is attached and, with the application of heat and pressure, the sleeve wrap networked.
Anschließend werden die äußere Leitschicht 10, gegebenenfalls ein metallischer Schirm 11 und ein äußerer Korrosionsschutz 12 aufgebracht, sofern diese Schichten auch auf der hohlrohrförmigen Kunststoffisolierung 3 vorhanden sind.Then the outer conductive layer 10, optionally a metallic screen 11 and an outer one Corrosion protection 12 applied, provided that these layers are also present on the hollow tubular plastic insulation 3 are.
Wenn die beiden zu verbindenden Hochspannungskabel mit einem metallischen Schirm zwischen äußerer Leitschicht und Korrosionsschutz ausgeführt sind, so ist dieser Schirm im Muffenbereich ebenfalls leitend oder isoliert und in jedem Fall längskraftschlüssig durchzuverbinden.If the two high-voltage cables to be connected with a metallic Shield between the outer conductive layer and corrosion protection are carried out, so is this shield in the sleeve area is also conductive or insulated and in any case to be connected through restrained locking.
Diese Verbindung aus beispielsweise gewickelten Metallbändern oder metallischen Halbschalen kann zusätzlich die Funktion eines Druckschutzes für die Verbindungsstelle übernehmen, sofern das Hochspannungskabel unter einem höheren inneren Luft- oder Wasserdruck steht.This connection of, for example, wound metal strips or metallic half-shells can also have the function of pressure protection for the Take over connection point, provided the high voltage cable is under a higher internal air or water pressure.
