Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines feststoffisolierten Schalterpols.The invention relates to a method for producing a solid-insulated switch pole.

Ein derartiges Verfahren ist beispielsweise aus der
WO 2004/038748 A1 bekannt und umfasst die Schritte:

  • Ausbilden eines Polschalengehäuses,
  • Montieren einer Vakuumschaltröhre in dem Polschalengehäuse und
  • Vergießen eines Zwischenraumes zwischen Polschalengehäuse und montierter Vakuumschaltröhre mit einer fluiden Ausgleichsmasse, welche nach dem Vergießen vernetzt und dadurch zu einem gel- oder gummiartigen Material wird.
Such a method is for example from the
WO 2004/038748 A1 known and includes the steps:
  • Forming a pole shell,
  • Mounting a vacuum interrupter in the pole shell and
  • Potting a gap between the pole shell and mounted vacuum interrupter with a fluid leveling compound, which crosslinks after casting and thereby becomes a gel or rubber-like material.

Die fluide Ausgleichsmasse ist dabei dazu vorgesehen, Unterschiede in thermischen Ausdehnungskoeffizienten des Polschalengehäuses und der Vakuumschaltröhre bzw. deren Gehäuse auszugleichen, indem durch die Fluide, ausgehärtete Ausgleichsmasse eine elastische Polsterungsschicht zwischen dem Polschalengehäuse und der Vakuumschaltröhre ausgebildet ist. Das Polschalengehäuse besteht dabei üblicherweise aus einem langzeitstabilen Kunststoff, beispielsweise aus einem Duroplast (z. B. Epoxidharz) oder einem Thermoplast (z. B. Polyamid) oder einem Kompositwerkstoff oder dergleichen. Die Vakuumschaltröhre ist als Schaltelement eines üblicherweise mehrphasig ausgebildeten Leistungsschalters, beispielsweise eines Mittelspannungsleistungsschalters, in dem Polschalengehäuse zur dielektrischen Isolierung angeordnet, wobei das Polschalengehäuse Anschlüsse aufweist, über die ein mittels der Vakuumschaltröhre zu schaltender Strom geführt ist. Die elastische Polsterungsschicht hat damit auch die Aufgabe, die beiden Anschlüsse zu isolieren und muss daher über eine ausreichende dielektrische Festigkeit verfügen.The fluid leveling compound is intended to compensate for differences in thermal expansion coefficients of the pole shell and the vacuum interrupter or their housing by an elastic cushioning layer between the pole shell and the vacuum interrupter is formed by the fluids, hardened leveling compound. The pole housing normally consists of a long-term stable plastic, for example of a duroplastic (for example epoxy resin) or a thermoplastic (for example polyamide) or a composite material or the like. The vacuum interrupter is arranged as a switching element of a usually multi-phase circuit breaker, for example, a medium-voltage circuit breaker in the pole shell for dielectric isolation, wherein the pole shell housing has connections over which a current to be switched by means of the vacuum interrupter is guided. The elastic padding layer has thus also the task of isolating the two terminals and therefore must have sufficient dielectric strength.

Aus der WO2000/41199A1 ist ein Verfahren bekannt, das folgende Schritte umfasst:

  • Ausbilden eines Polschalengehäuses;
  • Montieren einer Vakuumschaltröhre, die mit einer elastischen Schicht versehen ist, in das Polschalengehäuse.
From the WO2000 / 41199A1 a method is known which comprises the following steps:
  • Forming a pole shell;
  • Mounting a vacuum interrupter, which is provided with an elastic layer, in the pole shell.

Es wird also eine Vakuumschaltröhre mit einer elastischen Schicht versehen.Thus, a vacuum interrupter is provided with an elastic layer.

DE 199 06 972 offenbart ein Verfahren zur Herstellung eines feststoffisolierten Schalterpols gemäß dem Oberbegriff von Anspruch 1. DE 199 06 972 discloses a method for producing a solid-insulated switch pole according to the preamble of claim 1.

Aufgabe der vorliegenden Erfindung ist es, ein Verfahren zur Herstellung eines feststoffisolierten Schalterpoles anzugeben, welches einfach und kostengünstig ausführbar ist.The object of the present invention is to specify a method for producing a solid-state switch pole, which can be implemented simply and inexpensively.

Erfindungsgemäß gelöst wird dies durch ein Verfahren gemäß Anspruch 1.This is achieved according to the invention by a method according to claim 1.

Mit anderen Worten wird beim erfindungsgemäßen Verfahren in vorteilhafter Weise zunächst das Polschalengehäuse komplett mit einer mit dem Polschalengehäuse verbundenen elastischen Schicht im Inneren ausgebildet, so dass das Polschalengehäuse mit der stoffschlüssig verbundenen elastischen Schicht als Polsterung zusammen und unabhängig von der Vakuumschaltröhre hergestellt bzw. vorproduziert werden kann, und zur weiteren Ausbildung des feststoffisolierten Schalterpoles anschließend nur noch die Vakuumschaltröhre in dem mit der elastischen Schicht versehenen Bereich der Polschale bzw. des Polschalengehäuses montiert werden muss. Somit wird das Polschalengehäuse mit der elastischen Schicht als integralem Bestandteil des Polschalengehäuses ausgebildet. Stoffschlüssig im Sinne der vorliegenden Erfindung umfasst dabei auch ein sehr gutes aneinander Haften, beispielsweise von kompatiblen Werkstoffen.In other words, in the method according to the invention, the pole shell housing is initially formed completely with an elastic layer connected to the pole shell inside so that the pole shell with the cohesively connected elastic layer as a padding together and can be produced independently of the vacuum interrupter or pre-produced , And then for further formation of the solid-insulated Schalterpoles then only the vacuum interrupter in the provided with the elastic layer region of the pole shell or the pole housing must be mounted. Thus, the pole shell with the elastic layer is formed as an integral part of the pole shell. Cohesive in the sense of the present invention also includes a very good Stick together, for example, of compatible materials.

Gemäß der Erfindung umfasst der Schritt des Ausbildens des Polschalengehäuses mit der stoffschlüssig mit dem Polschalengehäuse verbunden elastischen Schicht die Schritte:

  • Ausbilden der elastischen Schicht;
  • Stoffschlüssiges Aufbringen des Polschalengehäuses auf die elastische Schicht.
According to the invention, the step of forming the pole shell with the layer elastically bonded to the pole shell comprises the steps of:
  • Forming the elastic layer;
  • Cohesive application of the pole shell to the elastic layer.

Bei einem derartigen Verfahren wird die elastische Schicht zunächst als separates, eigenes Bauteil ausgebildet, welches dann im nächsten Schritt mit dem Polschalengehäuse umgeben wird.In such a method, the elastic layer is first formed as a separate, separate component, which is then surrounded in the next step with the pole shell.

Das stoffschlüssige Verbinden von elastischer Schicht und Polschalengehäuse kann dabei unterschiedlich erfolgen, beispielsweise durch ein Spritzgussverfahren, oder besonders vorteilhaft durch ein Zwei-Komponenten-Spritzgussverfahren, bei dem im ersten Verfahrensschritt die elastische Schicht und im zweiten Verfahrensschritt das Polschalengehäuse aus einem langzeitstabilen, festen Kunststoff auf die elastische Schicht aufgespritzt wird, oder umgekehrt im ersten Schritt das Polschalengehäuse gefertigt wird und im zweiten Schritt die elastische Schicht in das Polschalengehäuse eingespritzt wird.The cohesive bonding of elastic layer and pole shell can be done differently, for example by an injection molding process, or particularly advantageously by a two-component injection molding process, in the first step, the elastic layer and in the second process step, the pole shell of a long-term stable, solid plastic the elastic layer is sprayed on, or conversely in the first step, the pole shell is made and in the second step, the elastic layer is injected into the pole shell.

Geeignete Materialien für die elastische Schicht sind dabei beispielsweise thermoplastische Elastomere, Silikon oder EPDM, wobei sich gegebenenfalls durch eine geeignete chemische oder physikalische Vorbehandlung die Verbindungsfestigkeit zwischen der elastischen Schicht und dem Polschalengehäuse noch weiter verbessern lässt.Suitable materials for the elastic layer are, for example, thermoplastic elastomers, silicone or EPDM, wherein, if appropriate, the bonding strength between the elastic layer and the pole shell can be further improved by suitable chemical or physical pretreatment.

Die stoffschlüssig mit dem Polschalengehäuse verbundene elastische Schicht kann dabei die Vakuumschaltröhre umschließen, oder einen Gehäusewandbereich der Vakuumschaltröhre teilweise umgeben. Durch vollständiges Umschließen der Vakuumschaltröhre oder auch teilweises Umgeben eines Gehäusewandbereiches der Vakuumschaltröhre ist eine ausreichende elastische Polsterung zwischen Vakuumschaltröhre und Polschalengehäuse gegeben, mittels der die Unterschiede in den thermischen Ausdehnungskoeffizienten von Vakuumschaltröhre und Polschalengehäuse ausgleichbar sind und gleichzeitig die dielektrische Isolierung der Anschlüsse sichergestellt ist.The cohesively connected to the pole shell housing elastic layer can enclose the vacuum interrupter, or partially surround a housing wall region of the vacuum interrupter. By completely enclosing the vacuum interrupter or even partially surrounding a housing wall region of the vacuum interrupter, there is sufficient elastic padding between the vacuum interrupter and the pole housing, by means of which the differences in the coefficients of thermal expansion of the vacuum interrupter and the pole housing can be compensated while the dielectric isolation of the connections is ensured.

Die Erfindung betrifft weiterhin einen feststoffisolierten Schalterpol.The invention further relates to a solid-insulated switch pole.

Ein feststoffisolierter Schalterpol ist ebenfalls aus der WO 2004/038748 A1 bekannt und umfasst ein Polschalengehäuse mit einem ersten Anschluss, einem zweiten Anschluss, einer Vakuumschaltröhre sowie einer zwischen Polschalengehäuse und Vakuumschaltröhre angeordnete elastische Schicht.A solid-insulated switch pole is also from the WO 2004/038748 A1 and comprises a pole shell with a first terminal, a second terminal, a vacuum interrupter and a arranged between the pole shell and vacuum interrupter elastic layer.

Aufgabe der vorliegenden Erfindung ist es, einen feststoffisolierten Schalterpol der oben beschriebenen Art weiterzubilden, welcher einfach und kostengünstig herstellbar ist.Object of the present invention is to develop a solid-state switch pole of the type described above, which is simple and inexpensive to produce.

Erfindungsgemäß gelöst wird dies durch einen feststoffisolierten Schalterpol, der oben beschriebenen Art dadurch, dass die elastische Schicht mit dem Polschalengehäuse gemäß einem Verfahren nach einer der obigen Ausführungsformen verbunden ist.This is achieved according to the invention by a solid-insulated switch pole, of the type described above, in that the elastic layer is connected to the pole shell according to a method according to one of the above embodiments.

Die Erfindung wird im Folgenden anhand eines Ausführungsbeispiels und der Zeichnung näher erläutert, deren einzige Figur eine schematische Ansicht eines Ausführungsbeispiels eines erfindungsgemäßen feststoffisolierten Schalterpoles zeigt.The invention will be explained in more detail below with reference to an embodiment and the drawing, the single FIGURE shows a schematic view of an embodiment of a solid-state insulated switchpole according to the invention.

Die Figur zeigt einen feststoffisolierten Schalterpol 1, welcher ein Polschalengehäuse 2 aufweist, welches vorzugsweise in einem Gießverfahren aus einem Epoxidharz oder einem ähnlichen, ein festes Polschalengehäuse ausbildendem Material gebildet ist. Ein erster Anschluss 3 sowie ein zweiter Anschluss 4 sind an dem feststoffisolierten Schalterpol 1 vorgesehen, welche zur Verbindung mit figürlich nicht weiter dargestellten Strom führenden Teilen einer Schaltanlage, in welcher ein Schalter mit einem oder mehreren derartigen feststoffisolierten Schalterpolen 1 angeordnet ist, vorgesehen sind. Zwischen dem ersten Anschluss 3 und dem zweiten Anschluss 4 ist eine Vakuumschaltröhre 5 angeordnet, welche einen figürlich nicht dargestellten Festkontakt sowie einen figürlich ebenfalls nicht dargestellten Bewegkontakt innerhalb eines Gehäuses 6 aufweist, wobei der Festkontakt über einen Festkontaktanschlussbolzen 7, der sich durch ein erstes metallisches Gehäuseteil 8 hindurch erstreckt, mit dem zweiten Anschluss 4 und der Bewegkontakt über einen Bewegkontaktanschlussbolzen 9, der sich durch ein zweites metallisches Gehäuseteil 10 hindurch erstreckt, mit dem ersten Anschluss 3 elektrisch leitend verbunden ist. Der Bewegkontaktanschlussbolzen 9 ist dabei über eine isolierende Schaltstange 11 mit einem figürlich ebenfalls nicht dargestellten Antrieb mechanisch gekoppelt zum Einleiten einer Antriebsbewegung zum Schließen bzw. Öffnen des Kontaktsystems aus Festkontakt und Bewegkontakt der Vakuumschaltröhre 5, und mittels eines flexiblen Leiters 12 mit dem ersten Anschluss 3 elektrisch leitend verbunden. Ein Gehäusewandbereich 13 des Gehäuses 6 der Vakuumschaltröhre 5, welche typischerweise als Keramikzylinder ausgebildet ist, ist von einer elastischen Schicht 14 im Ausführungsbeispiel vollständig umschlossen. Es kann im Sinne der vorliegenden Erfindung jedoch auch ausreichend sein, lediglich ein teilweises Umgeben des Gehäusewandbereiches 13 durch die elastische Schicht 14 auszubilden, wobei teilweise im Sinne der vorliegenden Erfindung bezüglich der axialen Erstreckung der elastischen Schicht 14 über den Gehäusewandbereich 13 des Gehäuses 6 der Vakuumschaltröhre 5 meint.The figure shows a solid-insulated switch pole 1, which has a pole shell 2, which is preferably formed in a casting process of an epoxy resin or a similar, a solid pole shell housing ausbildendem material. A first terminal 3 and a second terminal 4 are provided on the solid-insulated switch pole 1, which are provided for connection to current-carrying parts of a switchgear not shown in detail, in which a switch with one or more such solid-state switch poles 1 is arranged. Between the first terminal 3 and the second terminal 4, a vacuum interrupter 5 is arranged, which has a fixed contact figuratively not shown and a moving figured contact within a housing 6, wherein the fixed contact via a fixed contact terminal pin 7 extending through a first metallic housing part 8 extends, with the second terminal 4 and the moving contact via a Bewegkontaktanschlussbolzen 9, which extends through a second metallic housing part 10 therethrough, is electrically conductively connected to the first terminal 3. The Bewegkontaktanschlussbolzen 9 is mechanically coupled via an insulating shift rod 11 with a drive also figured not shown for initiating a drive movement for closing or opening the contact system of fixed contact and moving contact of the vacuum interrupter 5, and by means of a flexible conductor 12 to the first terminal 3 electrically conductively connected. A housing wall region 13 of the housing 6 of the vacuum interrupter 5, which is typically designed as a ceramic cylinder, is completely enclosed by an elastic layer 14 in the exemplary embodiment. However, it may also be sufficient in the sense of the present invention be, only a partial surrounding the housing wall portion 13 through the elastic layer 14 form, which means partially in the sense of the present invention with respect to the axial extent of the elastic layer 14 on the housing wall portion 13 of the housing 6 of the vacuum interrupter 5.

Im Ausführungsbeispiel der Figur weist das Polschalengehäuse 2 Hinterschneidungen 15, 16 derart auf, dass das Polschalengehäuse 2 außerhalb des Bereiches der elastischen Schicht 14 einen geringeren Innendurchmesser aufweist als im Bereich der elastischen Schicht. Dies ist insbesondere dann vorteilhaft, wenn zuerst die elastische Schicht 14 als Formteil ausgebildet wird und anschließend das Polschalengehäuse um das Formteil der elastischen Schicht durch Umgießen oder Umspritzen angeordnet wird. Die Hinterschneidungen 15, 16 sind dabei aber optional und nicht unbedingt notwendig.In the exemplary embodiment of the figure, the pole housing 2 has undercuts 15, 16 in such a way that the pole shell housing 2 has a smaller inner diameter outside the region of the elastic layer 14 than in the region of the elastic layer. This is particularly advantageous when first the elastic layer 14 is formed as a molded part and then the pole shell is arranged around the molding of the elastic layer by encapsulation or extrusion coating. The undercuts 15, 16 are but optional and not essential.

Die elastische Schicht 14 ist dabei stoffschlüssig mit dem Polschalengehäuse 2 des feststoffisolierten Schalterpoles 1 verbunden, beispielsweise durch Einbringen der elastischen Schicht 14 in das Polschalengehäuse 2 oder durch Anbringen des Polschalengehäuses 2 auf der vorgefertigten elastischen Schicht 14, so dass insbesondere eine Montage der Vakuumschaltröhre 5 in dem mit der elastischen Schicht 14 versehenen Polschalengehäuse 2 möglich ist. Die elastische Schicht 14 gewährleistet dabei einen Ausgleich von Ausdehnungsschwankungen, welche auf Grund der unterschiedlichen Temperaturausdehnungskoeffizienten der Vakuumschaltröhre 5 und insbesondere des Gehäuses 6 der Vakuumschaltröhre 5 und dem Polschalengehäuse 2 resultieren, sowie die nötige dielektrische Isolierung. Als Material für die elastische Schicht 14 sind dabei beispielsweise thermoplastische Elastomere, Silikone, Polyurethan oder EPDM möglich, wobei die elastische Schicht 14 beispielsweise mittels eines Spritzgussverfahrens, durch Besprühen oder durch Verkleben im Polschalengehäuse 2 eingebracht werden kann.The elastic layer 14 is materially connected to the pole shell 2 of the solid-insulated switch pole 1, for example by introducing the elastic layer 14 into the pole shell 2 or by attaching the pole shell 2 on the prefabricated elastic layer 14, so that in particular a mounting of the vacuum interrupter 5 in the provided with the elastic layer 14 pole shell 2 is possible. The elastic layer 14 ensures a compensation of expansion fluctuations, which result due to the different thermal expansion coefficients of the vacuum interrupter 5 and in particular of the housing 6 of the vacuum interrupter 5 and the pole shell 2, as well as the necessary dielectric insulation. As the material for the elastic layer 14, for example, thermoplastic elastomers, silicones, polyurethane or EPDM are possible, wherein the elastic layer 14 can be introduced, for example by means of an injection molding process, by spraying or by gluing in the pole shell 2.
