Ein solcher Vakuumschalter ist aus der Praxis bereits bekannt. Vakuumschalter kommen insbesondere in der Mittelspan- nung, also in einem Spannungsbereich zwischen IkV und 52kV, zur Anwendung. Auch in diesem Spannungsbereich treten insbesondere beim Schalten hoher Leistungen Lichtbögen auf, die beim Trennen der Schaltkontakte gezogen werden. Zur Löschung dieser Lichtbögen bei einem Stromnulldurchgang sind die Schaltkontakte in einer Vakuumkammer angeordnet, in der einSuch a vacuum switch is already known from practice. Vacuum switches are used in particular in medium voltage, ie in a voltage range between IkV and 52kV. Also in this voltage range occur in particular when switching high power arcs, which are drawn when disconnecting the switch contacts. To erase these arcs at a current zero crossing the switch contacts are arranged in a vacuum chamber in which a
Vakuum herrscht. Gemäß dem Stand der Technik ist in der Regel ein fest mit der Vakuumkammer verbundener Festkontakt sowie ein diesbezüglich beweglich geführter Bewegkontakt vorgesehen. Der Bewegkontakt kann sowohl als schwenkbares Schaltmes- ser aber auch als Hubkontakt ausgebildet sein, der dem Festkontakt in einer Längsrichtung gegenüberliegt und in dieser Längsrichtung beweglich geführt ist. Um die Bewegung des Bewegkontaktes in Längsrichtung und gleichzeitig eine vakuum- dichte Anbindung an die Vakuumkammer zu ermöglichen, ist ein Faltenbalg aus Metall vorgesehen, der einerseits mit der Vakuumkammer und andererseits mit dem Bewegkontaktstück verbunden ist. Die Antriebsbewegung des Vakuumschalters wird durch eine Antriebseinheit erzeugt, die beispielsweise als Feder- speicherantrieb oder als Magnetantrieb realisiert ist. Die von der Antriebseinheit erzeugte Antriebsbewegung wird über eine Schaltmechanik in das Bewegkontaktstück eingeleitet. Die Schaltmechanik umfasst die besagte Schaltstange, welche über einen leitenden Abschnitt verfügt, der sich zum Bewegkontakt- stück hin erstreckt. Zum elektrischen Verbinden dieses leitenden Abschnittes der Schaltstange mit einer Bewegkontaktan- schlussklemme sind Verbindungsmittel vorgesehen, die gemäß dem Stand der Technik als Gleitkontakt, Bandkontakt oder Rollenkontakt realisiert sind. In der Regel kommt ein Bandkon- takt zum Einsatz, der einen flexiblen elektrisch leitendenVacuum prevails. According to the state of the art, a fixed contact permanently connected to the vacuum chamber and a movable contact guided in this respect are generally provided. The moving contact can be used both as a swiveling but also be designed as a lifting contact, which is opposite to the fixed contact in a longitudinal direction and is movably guided in this longitudinal direction. In order to allow the movement of the moving contact in the longitudinal direction and at the same time a vacuum-tight connection to the vacuum chamber, a bellows made of metal is provided, which is connected on the one hand to the vacuum chamber and on the other hand to the moving contact piece. The drive movement of the vacuum switch is generated by a drive unit, which is realized for example as a spring accumulator drive or as a magnetic drive. The drive movement generated by the drive unit is introduced via a switching mechanism in the Bewegkontaktstück. The switching mechanism comprises said switching rod, which has a conductive portion which extends towards the Bewegkontakt- piece. For electrically connecting this conductive portion of the shift rod with a Bewegkontaktan- circuit terminal connecting means are provided, which are realized according to the prior art as a sliding contact, tape contact or roller contact. As a rule, a ribbon contact is used which has a flexible electrically conductive
Bandabschnitt aufweist, um eine Bewegung der Schaltstange zu ermöglichen. In der Kontaktstellung des Vakuumschalters fließt der Strom von der Festkontaktanschlussklemme über das Festkontaktstück, das Bewegkontaktstück, den elektrischen leitenden Abschnitt der Schaltstange und das flexible Verbindungsmittel zur Bewegkontaktanschlussklemme . Den flexiblen Verbindungsmitteln haftet jedoch der Nachteil an, dass diese gegenüber den restlichen Komponenten des Strompfades eine herabgesetzte Stromtragfähigkeit aufweisen, so dass es insbe- sondere bei hohen Kurzschlussströmen zu einem für viele Anwendungen nicht mehr tragbaren hohen Widerstand kommt. Bei hohen Schaltgeschwindigkeiten ist darüber hinaus eine aufwändige Verbindungstechnik für die flexiblen Verbindungsmittel erforderlich, da es beim schnellen Schalten zu hohen Rei- bungs- oder Biegungskräften kommt. Schließlich sind flexible Verbindungsmittel raumgreifend.Has band portion to allow movement of the shift rod. In the contact position of the vacuum switch, the current flows from the fixed contact terminal via the fixed contact piece, the moving contact piece, the electrically conductive portion of the switching rod and the flexible connecting means to the Bewegkontaktanschlussklemme. However, the disadvantage of the flexible connection means is that they have a reduced current carrying capacity compared to the remaining components of the current path, so that, in particular at high short-circuit currents, a high resistance which is no longer acceptable for many applications occurs. At high switching speeds, moreover, a complex connection technique for the flexible connection means is required, since it leads to high speeds during rapid switching. bending or bending forces. Finally, flexible connection means are expansive.
Aus dem Stand der Technik sind ferner konusförmige Kontakte bekannt. Konuskontakte werden gemäß dem Stand der Technik bei Schaltern mit zwei Kontaktanordnungen eingesetzt. Beim Einschalten des Schalters schließt beispielsweise der Konuskontakt zuerst, so dass der erwartete Lichtbogen am Konuskontakt entsteht. Die zweite Kontaktanordnung eilt der zuerst schlie- ßenden Kontaktanordnung nach, so dass diese ohne Lichtbogenbildung geschlossen werden kann. Aufgrund ihrer besseren Leitfähigkeit fließt der Strom, wenn beide Kontakte geschlossen sind, über die nacheilende zweite Kontaktanordnung. Eine Beschädigung der zweiten Kontaktanordnung in Folge des Licht- bogens ist jedoch vermieden.Cone-shaped contacts are also known from the prior art. Cone contacts are used according to the prior art in switches with two contact arrangements. For example, when the switch is turned on, the cone contact closes first, resulting in the expected arc at the cone contact. The second contact arrangement follows the first closing contact arrangement, so that it can be closed without arcing. Because of their better conductivity, when both contacts are closed, the current flows across the lagging second contact arrangement. However, damage to the second contact arrangement as a result of the arc is avoided.
Aufgabe der Erfindung ist es, einen Vakuumschalter der eingangs genannten Art bereitzustellen, der kompakt und aufwandsarm ist und insbesondere bei hohen Einschaltgeschwindig- keiten einen sicheren Strompfad mit einer hohen Stromtragfähigkeit zwischen den Anschlussklemmen des Vakuumschalters bereitstellt .The object of the invention is to provide a vacuum switch of the type mentioned, which is compact and low in complexity and especially at high Einschaltgeschwindig- speeds provides a safe current path with a high current carrying capacity between the terminals of the vacuum switch.
Die Erfindung löst diese Aufgabe dadurch, dass die Verbin- dungsmittel einen Klemmkontakt aufweisen, der über ein mit dem Leiterabschnitt der Schaltmechanik verbundenes Einführ- klemmkontaktstück und ein fest mit der Vakuumkammer und elektrisch mit der Bewegkontaktanschlussklemme verbundenes Gegenklemmkontaktstück verfügt, die so zueinander angeordnet sind, dass das Einführklemmkontaktstück infolge der Antriebsbewegung mit dem Gegenklemmkontaktstück elektrisch leitend verklemmt wird. Erfindungsgemäß ist ein Vakuumschalter bereitgestellt, der statt der üblichen Verbindungsmitteln einen Klemmkontakt aufweist. Aufgrund des Klemmkontaktes ist es möglich, einen Vakuumschalter mit ausschließlich fester Verschienung bereitzu- stellen. Die Schaltmechanik ist daher frei von einem flexiblen Leiterabschnitt, Roll- oder Schleifkontakten, die beim Schnellen schließen das Schaltkontaktes mechanische Probleme verursachen können. Erfindungsgemäß ist es daher möglich, den Vakuumschalter schnell zu schließen.The invention achieves this object in that the connecting means have a clamping contact which has an insertion clamping contact piece connected to the conductor section of the switching mechanism and a counter-clamping contact piece firmly connected to the vacuum chamber and electrically connected to the moving contact connection terminal the Einführklemmkontaktstück is electrically conductively clamped due to the drive movement with the counter-clamping contact. According to the invention, a vacuum switch is provided which has a clamping contact instead of the usual connection means. Due to the clamping contact, it is possible to provide a vacuum switch with only solid busbars. The switching mechanism is therefore free of a flexible conductor section, rolling or sliding contacts that close the switch contact can cause mechanical problems when fast. According to the invention it is therefore possible to close the vacuum switch quickly.
Darüber hinaus ist der Vakuumschalter auch kompakt und kann auch bei kleinen Einbauräumen ohne Probleme eingesetzt werden. Erfindungsgemäß verfügt der Klemmkontakt über zwei Kontaktstücke. Das Gegenklemmkontaktstück des Klemmkontaktes ist mechanisch fest mit der Bewegkontaktanschlussklemme verbunden und somit ortsfest angeordnet. Das zweite Kontaktstück des Klemmkontaktes, nämlich das Einführklemmkontaktstück, ist fest an der Schaltmechanik angebracht, wobei zwischen dem elektrisch leitenden Leiterabschnitt und dem Einführklemmkon- taktstück eine elektrische Verbindung bereitgestellt ist. Auf diese Weise ist das Bewegkontaktstück auch mit dem Einführklemmkontaktstück elektrisch verbunden. Spätestens in Folge des Einleitens der Schaltbewegung in die Schaltmechanik kommt es zur elektrischen Verbindung zwischen dem Einführklemmkon- taktstück und dem Gegenklemmkontaktstück und somit zu einer elektrischen Verbindung zwischen dem Bewegkontaktstück und der Bewegkontaktstückanschlussklemme . Flexible Verbindungsmittel sind erfindungsgemäß vermieden.In addition, the vacuum switch is also compact and can be used without problems even in small installation spaces. According to the invention, the clamping contact has two contact pieces. The counter-clamping contact of the terminal contact is mechanically fixed to the Bewegkontaktanschlussklemme and thus arranged stationary. The second contact piece of the clamping contact, namely the Einführklemmkontaktstück is fixedly mounted on the switching mechanism, wherein between the electrically conductive conductor portion and the Einführklemmkon- contact piece an electrical connection is provided. In this way, the Bewegkontaktstück is also electrically connected to the Einführklemmkontaktstück. At the latest as a result of the initiation of the switching movement in the switching mechanism, it comes to the electrical connection between the Einführklemmkon- contact piece and the counter-clamping contact piece and thus to an electrical connection between the Bewegkontaktstück and the Bewegkontaktstückanschlussklemme. Flexible connecting means are avoided according to the invention.
Vorteilhafterweise eilt der Klemmkontakt dem Schaltkontakt beim Schließen des Vakuumschalters zeitlich voraus. Gemäß dieser vorteilhaften Weiterentwicklung ist sichergestellt, dass kein Lichtbogen außerhalb der Vakuumkammer entsteht. Zweckmäßigerweise ist das Einführklemmkontaktstück so mit der Schaltmechanik verbunden, so dass beim Verklemmen der Kontaktstücke des Klemmkontaktes das Bewegkontaktstück abgebremst wird. Der Aufprall auf das Festkontaktstück ist daher gemäß dieser zweckmäßigen Weiterentwicklung der Erfindung we- niger heftig.Advantageously, the clamping contact leads the switch contact when closing the vacuum switch ahead of time. According to this advantageous further development, it is ensured that no arc arises outside the vacuum chamber. Conveniently, the Einführklemmkontaktstück is so with the Switching mechanism connected so that when jamming the contacts of the terminal contact the Bewegkontaktstück is slowed down. The impact on the fixed contact piece is therefore less violent according to this expedient development of the invention.
Gemäß einer bevorzugten Ausgestaltung der Erfindung ist die Antriebseinheit ein pyrotechnisches Kraftelement, wobei ein Zündkreis zum Auslösen des pyrotechnischen Kraftelementes vorgesehen ist. Pyrotechnische Kraftelemente ermöglichen ein besonders schnelles Schließen des Vakuumschalters. Durch das Zünden des pyrotechnischen Kraftelementes werden darüber hinaus hohe Einschaltkräfte erzeugt mit einem heftigen Aufschlagen des Bewegkontaktstückes im Gefolge. Im Rahmen der Erfin- düng kann es auch zum Verkeilen des Schaltkontaktes in Folge der hohen Aufprallkräfte kommen. Der Vakuumschalter kann daher nur einmal geschaltet und muss anschließend ausgetauscht werden .According to a preferred embodiment of the invention, the drive unit is a pyrotechnic force element, wherein an ignition circuit is provided for triggering the pyrotechnic force element. Pyrotechnic power elements allow a particularly fast closing of the vacuum switch. In addition, by the ignition of the pyrotechnic force element high Einschaltkräfte be generated with a violent opening of the moving contact in the wake. In the context of the invention fertil can also come to wedging of the switching contact as a result of the high impact forces. The vacuum switch can therefore only be switched once and then has to be replaced.
Gemäß einer diesbezüglich zweckmäßigen Weiterentwicklung weist der pyrotechnische Antrieb ein Verschiebeelement auf, das in Folge des Auslösens explosionsartig um eine Wegstrecke verschoben wird. Dabei ist die Schaltmechanik als sich in eine Längsrichtung erstreckende und mit dem Verschiebeelement verbundene Schaltstange realisiert, wobei das Verschiebeelement bis zum Auslösen des pyrotechnischen Antriebs zum Halten des Bewegkontaktsstückes in seiner Trennstellung eingerichtet ist. Gemäß dieser zweckmäßigen Weiterentwicklung ist der Schaltkontakt als so genannter Hubkontakt ausgestaltet. Mit anderen Worten ist der Bewegkontakt am Ende einer in die Vakuumkammer hinein ragenden Schaltstange gehalten. Dabei liegt das Bewegkontaktstück dem Festkontaktstück in der Längsrichtung gegenüber, in der sich auch die Schaltstange erstreckt. An dem vom Bewegkontaktstück abgewendeten Ende der Schalt- Stange ist der pyrotechnische Antrieb lokalisiert, wobei die Schaltstange mechanisch mit dem Verschiebeelement verbunden ist, das beispielsweise stiftförmig ausgebildet und fluchtend zur Schaltstange angeordnet ist. Der pyrotechnische Antrieb ist so ausgerichtet, dass bei einem Zünden des pyrotechni- schen Kraftelementes das Verschiebeelement in Längsrichtung auf den Festkontakt zu verschoben wird. Aufgrund der starren Verbindung zwischen Verschiebeelement und Bewegkontaktstück mittels der Schaltstange kommt es zu einer Verschiebung des Bewegkontaktstückes in Richtung des Festkontaktstückes. Dabei wird gleichzeitig das Einführklemmkontaktstück in das Gegen- klemmkontaktstück gepresst, wodurch der Strompfad zwischen den Anschlussklemmen des Vakuumschalters geschlossen wird. Vor dem Zünden des pyrotechnischen Kraftelementes stellt das Verschiebeelement eine Haltekraft bereit, die dem Schließen des Schaltkontaktes entgegensteht. Aufgrund des Druckunterschiedes im Inneren der Vakuumkammer und der Außenatmosphäre wirkt eine fortwährende Schließkraft, die das Bewegkontaktstück auf das Festkontaktstück treibt. Dem steht die Halte- kraft des Verschiebeelementes entgegen.According to an expedient further development, the pyrotechnic drive has a displacement element, which is displaced explosively by a distance as a result of triggering. In this case, the switching mechanism is realized as extending in a longitudinal direction and connected to the displacement element shift rod, wherein the displacement element is set up to trigger the pyrotechnic drive for holding the Bewegkontaktsstückes in its disconnected position. According to this expedient development of the switching contact is designed as a so-called Hubkontakt. In other words, the moving contact is held at the end of a switching rod protruding into the vacuum chamber. In this case, the Bewegkontaktstück the fixed contact piece in the longitudinal direction opposite, in which also extends the shift rod. At the end of the switching contact facing away from the moving contact piece Rod is located the pyrotechnic drive, wherein the shift rod is mechanically connected to the displacement element, which is for example designed pin-shaped and arranged in alignment with the shift rod. The pyrotechnic drive is oriented such that when the pyrotechnic force element is ignited the displacement element is displaced toward the fixed contact in the longitudinal direction. Due to the rigid connection between the displacement element and moving contact piece by means of the switching rod, there is a shift of the moving contact piece in the direction of the fixed contact piece. At the same time the Einführklemmkontaktstück is pressed into the counter clamping contact piece, whereby the current path between the terminals of the vacuum switch is closed. Before the ignition of the pyrotechnic force element, the displacement element provides a holding force that precludes the closing of the switching contact. Due to the pressure difference in the interior of the vacuum chamber and the outside atmosphere, a continuous closing force acts, which drives the moving contact piece onto the fixed contact piece. The opposite is the holding force of the displacement element.
Gemäß einer diesbezüglich zweckmäßigen Weiterentwicklung sind Positionierungsmittel zum Einstellen der räumlichen Lage des Verschiebeelementes und somit des Abstandes des Bewegkontakt- Stückes bezüglich des Festkontaktstückes vorgesehen. Solche Positionierungsmittel sind beispielsweise einfache Positionierungsschrauben, mit denen die Lage der pyrotechnischen Antriebseinheit und somit des Verschiebeelementes in einem gemeinsamen Haltegerüst veränderbar ist.According to an expedient further development, positioning means are provided for adjusting the spatial position of the displacement element and thus the distance of the Bewegkontakt- piece with respect to the fixed contact piece. Such positioning means are, for example, simple positioning screws, with which the position of the pyrotechnic drive unit and thus of the displacement element in a common holding frame is changeable.
Gemäß einer bevorzugten Ausgestaltung ist der Klemmkontakt ein Konuskontakt, der ein konusförmiges Einklemmkontaktstück sowie ein hierzu formkomplementäres Gegenklemmkontaktstück aufweist. Das Einklemmkontaktstück ist beispielsweise ein auf die zylinderförmige Schaltstange aufgesetzter Ring, der sich entgegen der Schaltbewegung in seinem Umfang fortwährend vergrößert, so dass im Querschnitt ein keilförmiges Einklemmkontaktstück bereitgestellt ist, durch dessen konzentrischen Hohlraum sich die Schaltstange erstreckt. Gemäß einer bevorzugten Ausgestaltung ist das Einklemmkontaktstück lose auf der Schaltstange angeordnet, wobei sich beim Einschalten des Schalters ein Klemmsitz des Einklemmkontaktstückes auf der Schaltstange ergibt. Abweichend hiervon kann das Einführ- klemmkontaktstück jedoch auch fest mit der Schaltstange verbunden sein, beispielsweise durch Klebemittel, Verschweißen, Verschrauben oder Aufschrumpfen.According to a preferred embodiment, the clamping contact is a cone contact, which has a cone-shaped Einklemmkontaktstück and a complementary form complementary Gegenklemmkontaktstück. The Einklemmkontaktstück is for example on the cylindrical switching rod attached ring which increases continuously against the switching movement in its circumference, so that in cross-section a wedge-shaped Einklemmkontaktstück is provided, extends through the concentric cavity, the shift rod. According to a preferred embodiment, the Einklemmkontaktstück is arranged loosely on the shift rod, wherein when switching on the switch results in a clamping fit of the Einklemmkontaktstückes on the shift rod. Deviating from this, however, the insertion clamp contact piece can also be firmly connected to the switching rod, for example by adhesive, welding, screwing or shrinking.
Gemäß einer vorteilhaften Weiterentwicklung liegt das Ein- klemmkontaktstück bereits in der Trennstellung lose an dem Gegenklemmkontaktstück an. Auf diese Weise ist sichergestellt, dass der Klemmkontakt den Schaltkontakt zeitlich auf jeden Fall vorauseilt.According to an advantageous further development, the clamping contact piece is already loosely attached to the counter-clamping contact piece in the disconnected position. In this way it is ensured that the terminal contact leads the switch contact in any case in time.
Vorteilhafterweise ist das Festkontaktstück von einer eineAdvantageously, the fixed contact piece of a
Wandung der Vakuumkammer durchgreifenden Kontaktstange gehalten, die außerhalb der Vakuumkammer zumindest mechanisch mit Haltemitteln zum Tragen des Vakuumschalters und zumindest elektrisch mit Kontaktmitteln verbunden ist, die galvanisch mit der Festkontaktanschlussklemme verbunden sind, wobei die Haltemitten den Kontaktmitteln aus Sicht des Festkontaktstückes nachgeschaltet sind. Gemäß dieser vorteilhaften Weiterentwicklung werden elektrische Wirbelströme vermieden, die ansonsten beobachtbar sind.Held wall of the vacuum chamber by cross-contact rod, which is outside the vacuum chamber at least mechanically connected to holding means for supporting the vacuum switch and at least electrically connected to contact means which are galvanically connected to the fixed contact terminal, wherein the holding means are arranged downstream of the contact means from the perspective of Festkontaktstückes. According to this advantageous development, electrical eddy currents which are otherwise observable are avoided.
Die Erfindung betrifft auch ein Umrichterventil zum Umrichten eines elektrischen Stromes oder einer elektrischen Spannung mit einer Reihenschaltung von bipolaren Submodulen, wobei jedes Submodul wenigstens einen Energiespeicher und eine Leis- tungshalbleiterschaltung aufweist, mit der die an dem Energiespeicher abfallende Spannung oder eine Nullspannung an dem Anschluss des zugeordneten Submoduls erzeugbar ist, und wobei jedem Submodul Überbrückungsmittel zum Überbrücken des Submo- duls im Fehlerfall zugeordnet sind.The invention also relates to an inverter valve for converting an electric current or an electrical voltage with a series circuit of bipolar submodules, each submodule having at least one energy store and one power supply. comprising a semiconductor circuit, with which the voltage dropping across the energy store or a zero voltage can be generated at the terminal of the associated submodule, and wherein each submodule is assigned bridging means for bridging the submodule in the event of a fault.
Solche Umrichterventile sind unter dem Begriff Multi-Level- Umrichter bereits bekannt geworden. Insbesondere sind solche Umrichterventile im Bereich der Energieübertragung und Ener- gieverteilung mit Erfolg anwendbar, so dass es einen ständig wachsenden Bedarf für solche Umrichterventile gibt. Im Fehlerfall eines der Submodule der Reihenschaltung ist es sinnvoll, das Submodul schnell zu überbrücken, so dass der Betrieb des Umrichterventils mit den restlichen Submodulen wei- ter fortgesetzt werden kann.Such converter valves have already become known under the term multi-level converter. In particular, such converter valves are successfully applicable in the field of energy transmission and energy distribution, so that there is an ever-increasing demand for such converter valves. In the event of a fault of one of the submodules of the series connection, it makes sense to bridge the submodule quickly, so that the operation of the converter valve with the remaining submodules can be continued further.
Aufgabe der Erfindung ist es daher auch, ein solches Umrichterventil bereitzustellen, das sicher, zuverlässig und schnell überbrückt werden kann.The object of the invention is therefore also to provide such a converter valve, which can be safely, reliably and quickly bridged.
Die Erfindung löst diese Aufgabe mit Überbrückungsmitteln, die einen Vakuumschalter gemäß der vorgenannten Art umfassen.The invention solves this problem with bridging means comprising a vacuum switch according to the aforementioned type.
Die Leistungshalbleiterschaltung zum Erzeugen einer Spannung an den Anschlussklemmen jedes Submoduls ist zweckmäßigerweise so eingerichtet, dass die an dem Energiespeicher abfallende Spannung invers ist. Mit anderen Worten ist durch die Leistungshalbleiterschaltung sowohl die an dem Energiespeicher, beispielsweise einem Kondensator, abfallende Spannung als auch die hierzu inverse Spannung erzeugbar. Voraussetzung hierfür ist, dass Energiespeicher und Leistungshalbleiterschalter eine so genannte Vollbrückenschaltung ausbilden, die auch als H-Brücke bezeichnet werden kann. Abweichend davon sind im Rahmen der Erfindung jedoch auch Halbbrückenschaltungen möglich.The power semiconductor circuit for generating a voltage at the terminals of each submodule is expediently arranged so that the voltage dropping across the energy store is inverse. In other words, both the voltage drop across the energy store, for example a capacitor, and the voltage inverse thereto can be generated by the power semiconductor circuit. The prerequisite for this is that energy storage and power semiconductor switch form a so-called full bridge circuit, which can also be referred to as H-bridge. Apart from However, half-bridge circuits are also possible within the scope of the invention.

Darüber hinaus ist die Vakuum- kammer 2 sowie der Festkontaktbolzen 3 über Haltemittel 9 ebenfalls ortsfest bezüglich des Traggerüstes 8 angeordnet. Kontaktmittel 10 sorgen weiterhin für eine elektrische Verbindung des Festkontaktbolzens 3 und somit des Festkontakt- Stückes mit einer Festkontaktanschlussklemme 11.The figure shows a cross-sectional view of an embodiment of the vacuum switch according to the invention 1. The vacuum switch 1 has a figured in the figure, not shown switching contact in a vacuum chamber 2. The vacuum interrupter chamber has a ceramic tube which extends between the contacts and acts as an insulator. In the vacuum chamber 2 projects into a fixed contact pin 3, which carries at its arranged in the vacuum chamber 2 end of the invisible fixed contact piece. In the longitudinal direction of the fixed contact piece is the Bewegkontaktstück, which is supported by the free end of a shift rod 4, which forms the switching mechanism of the vacuum switch 1. At its end 5, which is repelled by the loading contact piece, the switching rod 6 is firmly connected to a displacement element 6 of a pyrotechnic drive 7. To hold the pyrotechnic drive 7 is a figuratively not shown holding framework. Reference symbol 8 schematically illustrates the evaluation electronics of a control unit. For mechanical connection of the pole heads of the vacuum switch is a retaining strip 18, which extends between the pole heads and consists of an insulating material, for example of a glass fiber reinforced plastic. In addition, the vacuum Chamber 2 and the fixed contact pin 3 via holding means 9 also stationary with respect to the support frame 8 is arranged. Contact means 10 continue to provide an electrical connection of the fixed contact pin 3 and thus the fixed contact piece with a fixed contact terminal 11th
Die Schaltstange 4 ist in dem gezeigten Ausführungsbeispiel durchgehend leitend ausgebildet. Ein Klemmkontakt 12 dient zur elektrischen Verbindung der Schaltstange 4 und somit des figürlich nicht dargestellten Bewegkontaktstückes mit einer fest verschienten Bewegkontaktanschlussklemme 13. Zur längs beweglichen und gleichzeitig vakuumdichten Verbindung der Schaltstange 4 mit der Vakuumkammer 2 dient ein nur schematisch angedeuteter Metallfaltenbalg 14. Der Klemmkontakt 12 umfasst ein Einführklemmkontaktstück 16 sowie ein hierzu formkomplementäres Gegenklemmkontaktstück 17. Das Einführklemmkontaktstück 16 ist konusförmig ausgestattet, so dass es in der gezeigten Querschnittsansicht als Keil dargestellt ist .The shift rod 4 is formed continuously conductive in the embodiment shown. A clamping contact 12 is used for electrical connection of the shift rod 4 and thus the figured not Bewegkontaktstückes with a permanently verschied Bewegkontaktanschlussklemme 13.

Die figürlich dargestellte Vakuumkammer 2 dient zum Überbrücken eines Submoduls eines Umrichterventils, das über eine Reihenschaltung von gleichartig aufgebauten bipolaren Submo- dulen verfügt. Im Fehlerfall eines Submoduls kommt es zum Auftreten hoher Kurzschlussströme in dem Submodul mit Lichtbogenbildung im Gefolge. Zur Vermeidung eines solchen Lichtbogens und zum Aufrechterhalten des Betriebs des Stromrichterventils mit Hilfe der nicht beschädigten Submodule wird der Vakuumschalter 1 geschlossen. Hierzu wird zunächst der Kurzschlussstrom durch figürlich nicht dargestellte Sensoren in dem parallel zum Vakuumschalter 1 angeordneten Submodul erfasst. Neben dem im Submodul fließenden Strom kann auch die Spannung gemessen und der besagten Steuerungseinheit zugeführt werden. Wird ein zuvor in der Steuerungseinheit festge- legtes Kurzschlusskriterium erfüllt, sendet die Steuerungseinheit ein Zündsignal an das pyrotechnische Kraftelement 7. Es kommt zur explosionsartigen Verschiebung des Verschiebeelementes 7 und somit der Schaltstange 4. Hierbei wird die Schaltstange 4 in Richtung des Pfeils 15, also in Längsrichtung, verschoben. In Folge der Schaltbewegung kommt es auch zu einem festen Verklemmen des Einführklemmkontaktstückes mit dem Gegenklemmkontaktstück, wobei ein elektrischer Kontakt bereitgestellt ist. Kontaktiert das Bewegkontaktstück das Festkontaktstück, ist der Strompfad zwischen der Festkontakt- anschlussklemme 11 sowie der Bewegkontaktanschlussklemme 13 geschlossen . The figuratively illustrated vacuum chamber 2 is used to bridge a submodule of an inverter valve, which has a series circuit of identically constructed bipolar Submo- modules. In the event of a submodule fault, high short-circuit currents occur in the submodule with arcing in the wake. To avoid such an arc and to maintain the operation of the converter valve by means of the undamaged submodules, the vacuum switch 1 is closed. For this purpose, first of all the short-circuit current is detected by sensors (not shown) in the submodule arranged parallel to the vacuum switch 1. In addition to the current flowing in the submodule, the voltage can also be measured and supplied to said control unit. If a previously defined in the control unit The control unit sends an ignition signal to the pyrotechnic force element 7. It comes to the explosive displacement of the displacement element 7 and thus the shift rod 4. Here, the shift rod 4 in the direction of arrow 15, ie in the longitudinal direction, moved. As a result of the switching movement, there is also a firm jamming of the Einführklemmkontaktstückes with the counter-clamping contact piece, wherein an electrical contact is provided. If the moving contact piece contacts the fixed contact piece, the current path between the fixed contact connection terminal 11 and the moving contact connection terminal 13 is closed.
