Abstract
Description
Die Erfindung liegt auf dem Gebiet der elektrischen Schalter und ist bei der konstruktiven Ausgestaltung einer Vakuumschaltröhre anzuwenden, deren Gehäuse zwei relativ zueinander bewegbare Kontaktstücke umgibt und zwei koaxial zueinander angeordnete Keramikisolatoren gleichen Durchmessers aufweist, wobei die beiden Keramikisolatoren über ein als Schaltkammer ausgebildetes, zwischengefügtes Metallteil vakuumdicht miteinander verbunden sind.The invention is in the field of electrical switches and is used in the structural design of a vacuum interrupter, the housing surrounds two relatively movable contact pieces and two coaxial with each other arranged ceramic insulators same diameter, wherein the two ceramic insulators on a trained as a switching chamber, interposed metal part vacuum-tight connected to each other.
Bei einer bekannten Vakuumschaltröhre dieser Art sind die Kontaktstücke als sogenannte Axial-Magnetfeld-Kontakte in Topfform ausgebildet, jeweils mit einem Stromzuführungsbolzen versehen und um einen vorgegebenen Schalthub relativ zueinander axial bewegbar. Jeder Stromzuführungsbolzen ist dabei von einem der beiden Keramikisolatoren umgeben und an dem die Keramikisolatoren verbindenden Metallteil sind zylindrische Dampfschirme befestigt. Dieser Aufbau der Vakuumschaltröhre ermöglicht es, auch bei größeren Durchmessern der Kontaktstücke den Innendurchmesser der Keramikisolatoren kleiner als den Innendurchmesser der Schaltkammer zu bemessen. In diesem Fall ist es zweckmäßig, die Schaltkammer axial geteilt auszubilden. - Eine Vakuumschaltröhre dieser Art ist besonders zum Einsatz in Schaltanlagen auf der Mittelspannungsebene (15 bis 36 kV) geeignet (DE 197 13 478 C1).In a known vacuum interrupter of this type, the contact pieces are formed as so-called axial magnetic field contacts in cup form, each provided with a power supply pin and axially movable relative to each other by a predetermined switching stroke. Each power supply pin is surrounded by one of the two ceramic insulators and cylindrical metal screens are attached to the metal part connecting the ceramic insulators. This construction of the vacuum interrupter makes it possible to dimension the inner diameter of the ceramic insulators smaller than the inner diameter of the interrupter chamber, even with larger diameters of the contact pieces. In this case, it is expedient to form the switching chamber axially divided. - A vacuum interrupter of this type is particularly suitable for use in switchgear at the medium voltage level (15 to 36 kV) suitable (DE 197 13 478 C1).
Ausgehend von einer Vakuumschaltröhre mit den Merkmalen des Oberbegriffes des Patentanspruches 1 liegt der Erfindung die Aufgabe zugrunde, die Vakuumschaltröhre so auszugestalten, dass sie auch für Hochspannungszwecke, also für Betriebsspannungen von mehr als 60 kV (z. B. 72 kV, 84 kV) eingesetzt werden kann.Starting from a vacuum interrupter with the features of the preamble of claim 1, the invention has for its object to design the vacuum interrupter so that it also for high voltage purposes, ie for operating voltages of more than 60 kV (eg 72 kV, 84 kV) can be used.
Zur Lösung dieser Aufgabe ist gemäß der Erfindung vorgesehen, dass sowohl dem ersten als auch dem zweiten Keramikisolator jeweils ein weiterer, gleichartiger Keramikisolator koaxial und unmittelbar benachbart zugeordnet ist, wobei die beiden einander benachbarten Keramikisolatoren jeweils über ein zwischengefügtes Metallteil vakuumdicht miteinander verbunden sind, dass weiterhin an den zwischengefügten Metallteilen jeweils ein zylindrischer Dampfschirm befestigt ist und dass alle Dampfschirme mit axialem Abstand zueinander angeordnet sind.To achieve this object, it is provided according to the invention that both the first and the second ceramic insulator each coaxial and immediately adjacent to another similar ceramic insulator is associated, the two adjacent ceramic insulators are each connected via an interposed metal part vacuum-tight with each other, that continue a cylindrical vapor shield is fastened to each of the interposed metal parts, and all vapor shields are arranged at an axial distance from one another.
Eine derart ausgebildete Vakuumschaltröhre zeichnet sich dadurch aus, dass die erforderliche dielektrische Festigkeit bei sehr kleinem Bauvolumen erreicht wird und dass sie mit Fertigungseinrichtungen herstellbar ist, wie sie für Mittelspannungs-Röhren gebräuchlich sind. Durch die Ausgestaltung aller Dampfschirme mit zylindrischer Form und durch deren axial gestaffelte Anordnung kann der Durchmesser aller Keramikisolatoren relativ klein gewählt werden und liegt bei einer 72kV-Röhre bei etwa 130 mm. Die erforderliche Aufweitung der Vakuumschaltröhre im Bereich der eigentlichen Schaltstrecke hat keinen Einfluss auf den Durchmesser der Keramikisolatoren, da in diesem Bereich eine metallene Schaltkammer, zweckmäßig aus Kupfer, verwendet wird. Diese kann bauchförmig gestaltet sein, so dass sie an ihren Rändern mit den angrenzenden Keramikisolatoren trotz deren kleinerem Durchmesser vakuumdicht verbindbar ist.A vacuum interrupter formed in this way is distinguished by the fact that the required dielectric strength is achieved with a very small structural volume and that it can be produced with production equipment as is usual for medium-voltage tubes. Due to the design of all the vapor screens with a cylindrical shape and their axially staggered arrangement, the diameter of all ceramic insulators can be chosen relatively small and is at a 72kV tube at about 130 mm. The required widening of the vacuum interrupter in the region of the actual switching path has no effect on the diameter of the ceramic insulators, as in this area a metal switching chamber, suitably made of copper, is used. This may be designed bulbous, so that it is vacuum-tight at their edges with the adjacent ceramic insulators despite their smaller diameter.
Für die Funktion der Vakuumschaltröhre und hinsichtlich der für Keramikisolatoren größeren Durchmessers anfallenden Kosten ist es vorteilhaft, wenn der Innendurchmesser aller Keramikisolatoren höchstens gleich dem Außendurchmesser der Kontaktstücke plus dem einfachen Schalthub ist und wenn der Innendurchmesser des als Schaltkammer ausgebildeten Metallteiles höchstens gleich dem Außendurchmesser der Kontaktstücke plus dem zweifachen Schalthub ist. Dabei ist der relativ kleine Durchmesser der Schaltkammer durch die Verwendung von Axial-Magnetfeld-Kontakten für die Kontaktstücke ermöglicht.For the function of the vacuum interrupter and in terms of costs for ceramic insulators larger diameter costs It is advantageous if the inner diameter of all ceramic insulators is at most equal to the outer diameter of the contact pieces plus the simple switching stroke and if the inner diameter of the metal part designed as a switching chamber is at most equal to the outer diameter of the contact pieces plus the double switching stroke. In this case, the relatively small diameter of the switching chamber is made possible by the use of axial magnetic field contacts for the contact pieces.
Sofern die neue Vakuumschaltröhre für höhere Spannungen als 72 kV einsetzbar sein soll, kann eine Verlängerung der Röhre durch koaxiale Anordnung weiterer gleichartiger Keramikisolatoren und Zwischenfügung jeweils eines einen zylindrischen Dampfschirm tragenden Metallteiles erfolgen.If the new vacuum interrupter is to be used for voltages higher than 72 kV, an extension of the tube by coaxial arrangement of other similar ceramic insulators and Zwischenfügung each take a cylindrical vapor shield supporting metal part.
Vakuumschaltröhren mit vier koaxial angeordneten Keramikisolatoren und zwischengefügten Metallteilen sowie mit an den Metallteilen befestigten Dampfschirmen sind an sich bekannt. Bei einer bekannten, im Mittelspannungsbereich (34 kV) eingesetzten Röhre dieser Art sind die Dampfschirme konisch gestaltet und überlappen sich in axialer Richtung der Röhre. Dadurch haben die Keramikisolatoren einen relativ großen Durchmesser (US 3,792,214 A). - Es ist auch bekannt geworden, das aus drei auf schwebendem Potential befindlichen Schirmen bestehende Dampfschirmsystem bei einer Hochspannungs-Vakuumschaltröhre (72 kV) einzusetzen. Hierbei wurden für die Kontaktstücke spiralförmige Elektroden, gegebenenfalls unter zusätzlicher Verwendung einer äußeren Magnetspule, verwendet. Bei einer derartigen Vakuumschaltröhre haben die Keramikisolatoren einen relativ großen Durchmesser von 230 mm (Zeitschrift IEEE Transactions on Power Apparatus and Systems, Vol. PAS-99, No. 2 March/April 1980, Seiten 658 bis 666).Vacuum interrupters with four coaxial ceramic insulators and interposed metal parts as well as with attached to the metal parts steam shields are known per se. In a known, in the medium voltage range (34 kV) used tube of this type, the vapor screens are conical and overlap in the axial direction of the tube. As a result, the ceramic insulators have a relatively large diameter (US 3,792,214 A). - It has also become known to use the existing consisting of three floating on existing umbrellas steam shield system in a high-voltage vacuum interrupter (72 kV). In this case, helical electrodes were used for the contact pieces, optionally with the additional use of an external magnetic coil. In such a vacuum interrupter, the ceramic insulators have a relatively large diameter of 230 mm (Journal IEEE Transactions on Power Apparatus and Systems, Vol. PAS-99, No. 2 March / April 1980, pages 658 to 666).
Ein Ausführungsbeispiel der neuen Vakuumschaltröhre ist in der einzigen Figur der Zeichnung dargestellt.An embodiment of the new vacuum interrupter is shown in the single figure of the drawing.
Die in der Figur dargestellte Vakuumschaltröhre 1 weist eine Kontaktanordnung auf, die aus dem axial bewegbarem Kontaktstück 2 dem feststehenden Kontaktstück 3 besteht, wobei diese Kontaktstücke mit Stromzuführungsbolzen 4 bzw. 5 versehen sind. Die Kontaktstücke 2 und 3 sind in an sich bekannter Weise als topfförmige Axial-Magnetfeld-Kontakte ausgebildet (EP 0 155 376 C1).The vacuum interrupter 1 shown in the figure has a contact arrangement which consists of the axially
Die Kontaktanordnung ist in ein vakuumdichtes Gehäuse 6 eingeschlossen, das aus einer die Kontaktstücke umgebenden metallenen Schaltkammer 67, sich nach oben anschließenden Keramikisolatoren 64 und 63 sowie einer Deckplatte 61 und aus sich nach unten anschließenden Keramikisolatoren 65 und 66 sowie einer Deckplatte 62 besteht. Teil des Gehäuses ist weiterhin ein Faltenbalg 68, der zwischen den Stromzuführungsbolzen 4 des bewegbaren Kontaktstückes 2 und der Endplatte 61 angeordnet ist. Mit dem Gehäuse verbunden sind weiterhin Abschirmungen 70 und 73, die an den Rändern der Schaltkammer 67 befestigt sind, weiterhin Abschirmungen 72 und 75, die in die vakuumdichte Verbindung zwischen dem Keramikisolator 63 und der Endplatte 61 bzw. der Endplatte 62 und dem Keramikisolator 66 einbezogen sind, und schließlich Abschirmungen 71 und 74, die an ringförmigen Metallteilen befestigt sind, die zwischen jeweils zwei einander benachbarten Keramikisolatoren angeordnet sind.The contact arrangement is enclosed in a vacuum-tight housing 6, which consists of a metal switching chamber 67 surrounding the contact pieces,
Die aneinander angrenzenden Gehäuseteile sind miteinander sowie mit den beiden Stromzuführungsbolzen vakuumdicht verlötet.The adjoining housing parts are soldered vacuum-tight with each other and with the two power supply pins.
Die Dampfschirme 70 bis 75 sind jeweils zylindrisch ausgebildet und weisen umgebörtelte Ränder auf. Die jeweils zwei Keramikisolatoren zugeordneten Dampfschirme sind axial gestaffelt angeordnet, so dass sich untereinander Abstände A1 und A2 ergeben.The
Für das bewegbare Kontaktstück 2 ist ein Schalthub S vorgesehen, der bei einer Vakuumschaltröhre für 72 kV etwa 40 mm beträgt.For the
Die Keramikisolatoren 63 bis 66 weisen den gleichen Durchmesser D2 auf und sind bei dem dargestellten Ausführungsbeispiel auch untereinander gleich lang. Sie können aber auch unterschiedliche Längen aufweisen. - Im Vergleich zum Außendurchmesser D1 der Kontaktstücke ist der Innendurchmesser D2 der Keramikisolatoren kleiner als der Außendurchmesser D1 der Kontaktstücke plus dem einfachen Schalthub S. - Der Innendurchmesser D3 der Schaltkammer 67 braucht nicht größer als der Außendurchmesser D1 der Kontaktstücke plus dem zweifachen Schalthub S zu sein.The
Infolge der zylindrischen Form der Dampfschirme und der Verwendung einer bauchigen Schaltkammer ergibt sich eine insgesamt sehr schlanke Röhre, die ein relativ kleines Bauvolumen aufweist und sich darum ohne großen Aufwand entgasen lässt. Die das Gehäuse bildenden Metallteile und Keramikisolatoren können dabei so ausgestaltet und angeordnet werden, dass sämtliche das Gehäuse der Vakuumschalträume betreffenden Lötverbindungen in einem einzigen Arbeitsgang hergestellt werden, wobei auf die Verwendung eines Pumpstängels zur Entgasung der Röhre verzichtet werden kann. Dies wirkt sich positiv auf die dielektrische Festigkeit der Röhre aus.Due to the cylindrical shape of the vapor screens and the use of a bulbous switching chamber results in an overall very slim tube, which has a relatively small volume and therefore can be degassed without much effort. The housing forming metal parts and ceramic insulators can be designed and arranged so that all the housing of the vacuum interrupters concerned solder joints are made in a single operation, which can be dispensed with the use of a pump stalk for degassing of the tube. This has a positive effect on the dielectric strength of the tube.
