Abstract

A circuit-breaker pole insulated by solid material, with an electrically non-conductive and dimensionally stable insulating material housing. An interrupter is disposed in the housing. The interrupter has a fixed contact and a moving contact, which is located opposite the fixed contact on a drive side and is guided in a longitudinally movable manner. The insulating material housing is open on the drive side in order to allow the introduction of a drive movement into the moving contact. An elastic padding is arranged between the interrupter and the insulating material housing. The elastic padding has such self-adhesive properties that an adhesive bond that can only be abrasively released is obtained both with the interrupter and with the insulating material housing.

Description

Die Erfindung betrifft einen feststoffisolierten Schalterpol mit einem elektrisch nicht leitenden und formstabilen Isolierstoffgehäuse, in dem eine Schaltröhre angeordnet ist, die einen Festkontakt sowie einen diesem antriebseitig gegenüber liegenden und längs beweglich geführten Bewegkontakt aufweist, wobei das Isolierstoffgehäuse antriebsseitig geöffnet ist, um das Einleiten einer Antriebsbewegung in dem Bewegkontakt zu ermöglichen und wobei zwischen der Schaltröhre und dem Isolierstoffgehäuse eine elastische Polsterung angeordnet ist.The invention relates to a solid-insulated switch pole with an electrically non-conductive and dimensionally stable insulating material in which a switch tube is arranged, which has a fixed contact and a drive side opposite and longitudinally movable guided contact, the insulating housing is open on the drive side to initiate a drive movement to allow in the moving contact and wherein between the interrupter and the insulating material, an elastic padding is arranged.

Ein derartiger Schalterpol ist beispielsweise aus der US 2004 144757 bekannt.Such a switch pole is for example from the US 2004 144757 known.

Ein anderer Schalterpol ist aus der EP0866481A2 bereits bekannt. Der dort offenbarte Schalterpol weist ein starres oder mit anderen Worten ein formstabiles Isolierstoffgehäuse auf, in dem eine Vakuumschaltröhre befestigt ist. Die Vakuumröhre weist einen ortsfesten Festkontakt auf, der mit einem aus dem Isolierstoffgehäuse herausgeführten Anschlussstück fest verbunden ist. Dem Festkontakt gegenüberliegend ist ein Bewegkontakt angeordnet, der bezüglich des Festkontaktes längs beweglich geführt ist. Dabei ragen Festkontakt und Bewegkontakt in das Innere der Vakuumschaltröhre hinein. In der Vakuumschaltröhre herrscht ein Vakuum, welches das Löschen eines beim Öffnen zwischen den Kontakten gezogenen Lichtbogens unterstützt. Um das Einleiten einer Antriebsbewegung in den Bewegkontakt zu ermöglichen, weist das Isolierstoffgehäuse antriebsseitig eine Eingangsöffnung auf, durch die sich eine Schaltstange erstreckt, welche über eine zweckmäßige Hebelmechanik mit einer Antriebseinheit verbunden ist. Der Bewegkontakt ist über einen flexiblen Bandleiter mit einem zweiten Anschlussstück verbunden, das ebenfalls aus dem Isolierstoffgehäuse hinausgeführt und somit von außen kontaktierbar ist. Im eingeschalteten Zustand liegt der Bewegkontakt an dem Festkontakt an, so dass zwischen den aus dem Isolierstoffgehäuse herausgeführten Anschlussstücken eine leitende Verbindung hergestellt ist. Zum Unterbrechen des Stromflusses werden die Kontakte durch Einleiten einer Antriebsbewegung voneinander getrennt, wobei der Lichtbogen bei einem Stromnulldurchgang der Vakuumschaltröhre gelöscht wird.Another switch pole is out of the EP0866481A2 already known. The switch pole disclosed therein has a rigid or in other words a dimensionally stable insulating housing in which a vacuum interrupter is attached. The vacuum tube has a stationary fixed contact, which is firmly connected to a led out of the insulating housing connector. The fixed contact opposite a moving contact is arranged, which is guided longitudinally movable with respect to the fixed contact. In this case, fixed contact and moving contact protrude into the interior of the vacuum interrupter. There is a vacuum in the vacuum interrupter which helps to extinguish an arc drawn between the contacts when opened. In order to enable the initiation of a drive movement in the moving contact, has the insulating housing on the drive side an input opening through which a shift rod extends, which is connected via a suitable lever mechanism with a drive unit. The moving contact is connected via a flexible band conductor with a second connecting piece, which is also led out of the insulating material and thus contacted from the outside. When switched on, the moving contact abuts against the fixed contact, so that a conductive connection is established between the connecting pieces led out of the insulating housing. To interrupt the flow of current, the contacts are disconnected by initiating a drive motion, whereby the arc is extinguished at a current zero crossing of the vacuum interrupter.

Um Lufteinschlüsse und somit hohe Spannungsspitzen zu vermeiden, ist zwischen der Vakuumschaltröhre und dem formstabilen Isolierstoffgehäuse eine elastische Polsterung aus Ethylenpropylen, Kautschuk, Silikon oder Silikongummi vorgesehen. Die elastische Polsterung gleicht unterschiedliche Wärmekoeffizienten der Vakuumkammmer aus und verhindert so eine Rissbildung im starren Isolierstoffgehäuse. Zur Herstellung des feststoffisolierten Schalterpols wird die elastische Polsterung als Schrumpfschlauch über die Vakuumröhre gestülpt. Anschließend wird die Vakuumschaltröhre im Gussformverfahren in das Isolierstoffgehäuse eingegossen.In order to avoid air pockets and thus high voltage peaks, an elastic padding of ethylene propylene, rubber, silicone or silicone rubber is provided between the vacuum interrupter and the dimensionally stable insulating housing. The elastic padding compensates for different thermal coefficients of the vacuum chamber and thus prevents cracking in the rigid insulating material. To produce the solid-insulated switch pole, the elastic padding is slipped over the vacuum tube as a shrink tube. Subsequently, the vacuum interrupter is poured in the casting mold in the insulating material.

Dem vorbekannten feststoffisolierten Schalterpol haftet der Nachteil an, dass es trotz der elastischen Polsterung zu Lufteinschlüssen kommen kann. Aufgrund der dabei entstehenden Spannungsspitzen besteht, insbesondere bei höheren Spannungen, die Gefahr von Kriechströmen oder Teilentladungen.The previously known solid-insulated Schalterpol adheres to the disadvantage that it can lead to air pockets despite the elastic padding. Due to the resulting voltage peaks, especially at higher voltages, the risk of leakage currents or partial discharges.

Aus der DE 22 40 106 ist eine Hochleistungsdurchführung mit eingekapseltem Vakuumschalter bekannt. Dabei ist die Vakuumschaltröhre vollständig in dem Isolierkörper der Durchführung eingebettet. Um Rissbildung durch Wärmeausdehnung zu vermeiden, ist zwischen dem formstabilen Isolierkörper und der Vakuumschaltröhre ein elastisches Polster vorgesehen. Zur Herstellung der Durchführung wird die Vakuumschaltröhre mit einer Schicht aus einem elastischen Material überzogen, das beispielsweise ein Verkittungs- oder Klebmaterial ist. Anschließend wird der Epoxydharz des Isolierstöffgehäuses um die Vakuumröhre gepresst. Die dort offenbarte elastische Polsterung ist flexibel und haftet sowohl an der Vakuumröhre als auch an dem einkapselnden Isolierstoffgehäuse an. Aufgrund des Herstellungsverfahrens beträgt die Dicke der elastischen Polsterung zwischen 1 mm und etwa 6 mm. Als Material für die elastische Polsterung sind Polyurethane und Polysulfide angegeben.From the DE 22 40 106 is a high performance feedthrough with encapsulated vacuum switch known. The vacuum interrupter is completely embedded in the insulating body of the implementation. To avoid cracking due to thermal expansion, an elastic pad is provided between the dimensionally stable insulating body and the vacuum interrupter. To make the implementation, the vacuum interrupter is coated with a layer of an elastic material, which is for example a cement or adhesive material. Subsequently, the epoxy resin of Isolierstöffgehäuses is pressed around the vacuum tube. The elastic padding disclosed therein is flexible and adheres to both the vacuum tube and the encapsulating insulating housing. Due to the manufacturing process, the thickness of the elastic padding is between 1 mm and about 6 mm. As a material for the elastic padding polyurethanes and polysulfides are given.

Aufgabe der Erfindung ist es, eine feststoffisolierten Schalterpol der eingangsgenannten Art bereitzustellen, der einfach herstellbar ist und bei dem Lufteinschlüsse zwischen Schaltröhre und Isolierstoffgehäuse vermieden sind.The object of the invention is to provide a solid-insulated switch pole of the type mentioned, which is easy to manufacture and are avoided in the air pockets between the interrupter and insulating material.

Die Erfindung löst diese Aufgabe dadurch, dass die elastische Polsterung über solche Eigenhaftungseigenschaften verfügt, dass sowohl mit der Schaltröhre als auch mit dem Isolierstoffgehäuse ein nur abrasiv lösbarer Oberflächenverbund bereitgestellt ist, bei dem ein nur abrasiv lösbarer Oberflächenverbund bereitgestellt ist, bei dem die Oberflächenhaftung der elastischen Polsterung sowohl an der Schaltröhre als auch am Isolierstoffgehäuse größer als die Reiß- und/oder Weiterreißfestigkeit der elastischen Polsterung ist.The invention solves this problem in that the elastic padding has such Eigenhaftungseigenschaften that both with the interrupter and with the Isolierstoffgehäuse a only abradable releasable surface composite is provided in which an abrasive only releasable surface composite is provided in which the surface adhesion of the elastic Padding on both the interrupter and the insulating material is greater than the tear and / or tear strength of the elastic padding.

Die elastische Polsterung besteht erfindungsgemäß aus einem selbst haftenden Material, dass eine so hohe Oberflächenhaftung auf dem formstabilen Isoliergehäuse einerseits und dem Gehäuse der Schaltröhre andererseits entfaltet, dass auch über längere Betriebsdauern hinweg das Entstehen von Lufteinschlüssen zwischen Isolierstoffgehäuse und Schaltröhre vermieden ist. Aufgrund der großen Haftwirkung kommt es zu einer sicheren Halterung der Schaltröhre in dem Isolierstoffgehäuse. Aus diesem Grund ist es möglich, das Isolierstoffgehäuse so zu dimensionieren, dass ein nachträglicher Einbau der Schaltröhre in das Isolierstoffgehäuse ermöglicht ist. Erfindungsgemäß ist es daher möglich, das Isolierstoffgehäuse und die Vakuumschaltröhre unabhängig voneinander herzustellen, die Vakuumschaltröhre anschließend in dem Isolierstoffgehäuse zu befestigen und schließlich mit der elastischen Polsterung zu umgeben, welche die feste und gleichzeitig elastische Halterung der Vakuumschaltröhre ermöglicht. Unter dem Begriff abrasiv ist im Rahmen der Erfindung zu verstehen, dass die Oberflächenhaftung der elastischen Polsterung sowohl an der Schaltröhre als auch am Isolierstoffgehäuse größer als die Reiß- und/oder Weiterreißfestigkeit der elastischen Polsterung ist.The elastic padding according to the invention consists of a self-adhesive material that unfolds such a high surface adhesion to the dimensionally stable insulating housing on the one hand and the housing of the interrupter on the other hand, that over longer periods of operation, the emergence of air pockets between insulating material and interrupter tube is avoided. Due to the large adhesive effect, it comes to a secure mounting of the interrupter in the insulating material. For this reason, it is possible to dimension the insulating material so that a subsequent installation of the interrupter is made possible in the insulating material. According to the invention, it is therefore possible to manufacture the insulating material housing and the vacuum interrupter independently of one another, then to fasten the vacuum interrupter in the insulating material housing and finally to surround it with the elastic padding which enables the solid and elastic retaining of the vacuum interrupter. The term abrasive is to be understood in the context of the invention that the surface adhesion of the elastic padding on both the interrupter and the insulating housing is greater than the tear and / or tear strength of the elastic padding.

Vorteilhafterweise wird die Eigenhaftung der elastischen Polsterung auch an unbehandelten Oberflächen bereitgestellt. Der aufwändige Einsatz einer Oberflächenbehandlung mit Primern oder dergleichen zum Bereitstellen der Haftwirkung entfällt somit erfindungsgemäß wodurch sich die Herstellungskosten noch weiter absenken lassen.Advantageously, the inherent adhesion of the elastic padding is also provided on untreated surfaces. The elaborate use of a surface treatment with primers or the like to provide the adhesive effect thus eliminates the invention whereby the manufacturing cost can be lowered even further.

Zweckmäßigerweise weist die elastische Polsterung eine Durchschlagsfestigkeit von wenigstes 20 KV/mm auf. Durch diese hohe Durchschlagsfestigkeit ist eine kompakte Konstruktion des erfindungsgemäßen feststoffisolierten Schalterpols bereitgestellt.Conveniently, the elastic padding has a dielectric strength of at least 20 KV / mm. This high dielectric strength provides a compact construction of the solid-state switch pole according to the invention.

Zweckmäßigerweise weist die Härte der elastischen Polsterung einen Shore 00 oder Shore A Wert auf, der zwischen 30 und 40 liegt.Conveniently, the hardness of the resilient padding has a Shore 00 or Shore A value that is between 30 and 40.

Die Reißdehnung liegt zweckmäßigerweise zwischen 120 und 500%.The elongation at break is suitably between 120 and 500%.

Vorteilhafterweise ist die elastische Polsterung porenfrei. Durch die Porenfreiheit ist das Auftreten von Spannungsspitzen vermieden.Advantageously, the elastic padding is non-porous. The absence of pores avoids the occurrence of voltage peaks.

Bei der Schaltröhre handelt es sich vorteilhafterweise um eine Vakuumschaltröhre, die beispielsweise aus einem zylindrischen Keramikgehäuse besteht, das stirnseitig von zwei Metallkappen abgedeckt ist. Die Metallkappen werden jeweils von Kontaktstücke tragenden Kontaktstangen durchgriffen, wobei ein Festkontakt fest mit der ihm zugeordneten Metallkappe verbunden ist. Der dem Festkontakt in Längsrichtung gegenüber liegende Bewegkontakt ist mittels eines Metallfaltenbalges mit einer Stirnkappe verbunden, so dass dieser bezüglich des Festkontaktes längs beweglich geführt ist. Der Bewegkontakt ist über teilweise isolierende Schaltstangen sowie über eine Hebelmechanik mit einer Antriebseinheit verbunden, deren Antriebsbewegung in den Bewegkontakt eingeleitet wird.In the interrupter is advantageously a vacuum interrupter, which consists for example of a cylindrical ceramic housing, which is frontally covered by two metal caps. The metal caps are penetrated by contact rods carrying contact rods, wherein a fixed contact is firmly connected to the associated metal cap. The fixed contact in the longitudinal direction opposite moving contact is connected by means of a metal bellows with an end cap, so that it is guided longitudinally movable with respect to the fixed contact. The moving contact is connected via partially insulating shift rails and via a lever mechanism with a drive unit whose drive movement is introduced into the moving contact.

Das formstabile Isolierstoffgehäuse besteht beispielsweise aus Gießharz.The dimensionally stable insulating material consists for example of cast resin.

Weitere zweckmäßige Ausgestaltungen und Vorteile der Erfindung sind Gegenstand der nachfolgenden Beschreibung von Ausführungsbeispielen der Erfindung unter Bezug auf die Figur der Zeichnung, wobei dieFurther expedient embodiments and advantages of the invention are the subject of the following description of exemplary embodiments of the invention with reference to the figure of the drawing, wherein the

Figur ein Ausführungsbeispiel eines erfindungsgemäßen feststoffisolierten Schalterpols in einer geschnittenen Seitenansicht zeigt.Figure shows an embodiment of a solid-state insulated switch pole according to the invention in a sectional side view.

Die Figur zeigt in einer Querschnittsansicht ein Ausführungsbeispiel eines erfindungsgemäßen feststoffisolierten Schalterpols 1. Der feststoffisolierte Schalterpol 1 ist zur Unterbrechung des Stromflusses in einer Phase eines Drehspannungsnetzes vorgesehen. Da übliche Drehspannungsnetze drei Phasen aufweisen, sind bei marktgängigen Schaltern üblicherweise drei nebeneinander aufgestellte feststoffisolierte Schalterpole 1 vorgesehen, die mit einer gemeinsamen Antriebseinheit verbunden sind.The figure shows a cross-sectional view of an embodiment of a solid-state insulated switch pole according to the invention 1. The solid-insulated switch pole 1 is provided to interrupt the flow of current in one phase of a three-phase voltage network. Since conventional three-phase voltage networks have three phases, usually three juxtaposed solid-insulated switch poles 1 are provided with marketable switches, which are connected to a common drive unit.

Der gezeigte feststoffisolierte Schalterpol 1 weist ein aus Epoxidharz oder mit anderen Worten Gießharz geformtes Isolierstoffgehäuse 2 auf, in dem ein oberes Anschlussstück 3 und ein in der Figur nicht dargestelltes mittleres Anschlussstück befestigt sind. In dem Isolierstoffgehäuse 2 ist ferner eine Vakuumschaltröhre 4 erkennbar, die über eine Festkontaktstange 5 starr mit dem Anschlussstück 3 verbunden ist. Die Festkontaktstange 5 durchgreift eine aus Kupfer bestehende Stirnkappe 6, wobei Sie an ihrem im Inneren der Vakuumschaltröhre 4 angeordneten Ende einen figürlich nicht dargestellten Festkontakt trägt. Die Stirnkappe 6 ist vakuumdicht mit einem aus Keramik bestehenden hohlzylindrischen Vakuumgehäuse 7 verbunden, das an seiner der ersten Stirnkappe 6 gegenüberliegenden Seite eine zweite Stirnkappe 8 aufweist, die wiederum von einer Bewegkontaktstange 9 durchgriffen wird. Die Bewegkontaktstange 9 trägt an ihrem in die Vakuumröhre 4 hinragenden Ende einen Bewegkontakt, der dem Festkontakt gegenüberliegt und durch Einleiten einer Antriebsbewegung über eine figürlich nicht dargestellte Schaltstange in Kontakt mit dem Festkontakt gerät.The solid-state switch pole 1 shown has a molded from epoxy resin or in other words cast resin insulating material 2, in which an upper connector 3 and not shown in the figure middle connector are attached. In the insulating housing 2, a vacuum interrupter 4 is further recognizable, which is connected via a fixed contact rod 5 rigidly connected to the connector 3. The fixed contact rod 5 passes through an existing copper end cap 6, wherein it carries at its arranged in the interior of the vacuum interrupter 4 end a figuratively not shown fixed contact. The end cap 6 is vacuum-tightly connected to a hollow cylindrical vacuum housing 7 made of ceramic, which on its side opposite the first end cap 6 has a second end cap 8, which in turn is penetrated by a moving contact rod 9. The Bewegkontaktstange 9 carries at its end projecting into the vacuum tube 4 a moving contact, which faces the fixed contact and device by introducing a drive movement via a figuratively not shown switching rod in contact with the fixed contact.

Zur längs beweglichen Führung des Bewegkontaktes ist ein ebenfalls figürlich nicht dargestellter Faltenbalg vorgesehen, der mit seinem einen Ende mit der Stirnkappe 8 und mit seinem anderen Ende mit dem Bewegkontakt vakuumdicht verbunden ist.For longitudinally movable guidance of the moving contact a likewise figuratively not shown bellows is provided, which is connected in a vacuum-tight manner with its one end to the end cap 8 and with its other end to the moving contact.

Im Inneren des aus den Stirnkappen 6 und 8 sowie dem Keramikgehäuse 7 bestehenden Vakuumgehäuse herrscht ein Vakuum, welches das Löschen eines beim Trennen der Kontakte gezogenen Lichtbogens bei einem Nulldurchgang eines Wechselstromes unterstützt. Die Bewegkontaktstange 9 ist über ein figürlich nicht dargestelltes Leiterband elektrisch mit dem zweiten Kontaktstück verbunden, so dass in einer Kontaktstellung ein Stromfluss zwischen dem Anschlussstück 3 und dem zweiten Anschlussstück ermöglicht ist.In the interior of the existing of the end caps 6 and 8 and the ceramic housing 7 vacuum housing, there is a vacuum which supports the deletion of an arc drawn when disconnecting the contacts at a zero crossing of an alternating current. The Bewegkontaktstange 9 is electrically connected via a figuratively not shown conductor strip with the second contact piece, so that in a contact position, a current flow between the connector 3 and the second connector is possible.

Aufgrund unterschiedlicher Wärmeausdehnungskoeffizienten kommt es bei Temperaturveränderungen zu unterschiedlichen Wärmeausdehnungen der Bauteile der Vakuumschaltröhre 4. Um Lufteinschlüsse zu vermeiden, ist daher zwischen der Vakuumschaltröhre 4 und dem Isolierstoffgehäuse 2 eine elastische Polsterung 10 vorgesehen. Die elastische Polsterung 10 weist so hohe Eigenhaftungskräfte auf, dass diese die Vakuumschaltröhre 4 fest mit dem Isolierstoffgehäuse 2 verbindet. Dabei weist die elastische Polsterung eine Reißdehnung von etwa 200% sowie eine hohe Durchschlagsfestigkeit auf, so dass die notwendige dielektrische Festigkeit der Vakuumschaltröhre 4 bereitgestellt ist. Aufgrund der großen Selbsthaftung ist auch bei längeren Betriebsdauern unter hohen Umweltbelastungen das Entstehen von Lufteinschlüssen vermieden.Due to different coefficients of thermal expansion occurs at temperature changes to different thermal expansion of the components of the vacuum interrupter 4. In order to avoid air pockets, therefore, an elastic padding 10 is provided between the vacuum interrupter 4 and the insulating 2. The elastic padding 10 has such high inherent adhesion forces that it connects the vacuum interrupter 4 fixed to the insulating material 2. In this case, the elastic padding has an elongation at break of about 200% and a high dielectric strength, so that the necessary dielectric strength of the vacuum interrupter 4 is provided. Due to the great self-adhesion, the generation of air bubbles is avoided even with longer operating times under high environmental impact.

Dabei weist die elastische Polsterung eine dicke zwischen etwa 0,3 cm bis 3 cm auf, so dass ein bequemer Einbau der Vakuumschaltröhre in das formstabile Isolierstoffgehäuse 2 ermöglicht ist. So ist es beispielsweise erfindungsgemäß möglich, das Isolierstoffgehäuse 2 im Formgussverfahren auszubilden. Anschließend wird das Anschlussstück 3 mit der Festkontaktstange 4 verschraubt und die elastische Polsterung 10 eingefüllt.In this case, the elastic padding has a thickness between about 0.3 cm to 3 cm, so that a convenient installation of the vacuum interrupter in the dimensionally stable insulating housing 2 is possible. For example, it is possible according to the invention form the insulating material 2 in the casting process. Subsequently, the connector 3 is screwed to the fixed contact rod 4 and the elastic padding 10 filled.
