Abstract
Description
Die Erfindung bezieht sich auf eine Kontaktanordnung für einen elektrischen Leistungsschalter, insbesondere einen Hochspannungsleistungsschalter mit einem ersten Kontaktstück und mit einem diesem koaxial gegenüberstehenden rohrförmigen Tulpenkontaktstück, das radial federnde Kontaktfinger aufweist, welche an ihren dem ersten Kontaktstück abgewandten Enden mit einem Rohrstück verbunden sind.The invention relates to a contact arrangement for an electrical circuit breaker, especially one High-voltage circuit breaker with a first contact piece and with a tubular coaxial opposite this Tulip contact piece, which has radially resilient contact fingers, which facing away from the first contact piece Ends are connected with a piece of pipe.
Eine Kontaktanordnung für einen Hochspannungsleistungsschalter mit einem Tulpenkontaktstück und einem stiftförmigen Gegenkontaktstück ist bereits aus der DE-OS 28 53 201 bekannt. Dort ist das Tulpenkontaktstück auf seiner Innenseite mit einer Isolierschicht ausgekleidet.A contact arrangement for a high voltage circuit breaker with a tulip contact piece and a pin-shaped one Counter contact piece is already known from DE-OS 28 53 201. There is the tulip contact piece on the inside lined with an insulating layer.
Solche Leistungsschalter sind beispielsweise als Hochspannungsleistungsschalter in Form von Isolierdüsenschaltern bekannt, bei denen ein stiftförmiges Kontaktstück einem tulpenförmigen Kontaktstück gegenübersteht. Im Ausschaltfall wird das tulpenförmige Kontaktstück mittels eines Schalterantriebes von dem stiftförmigen Kontaktstück getrennt. Im Einschaltzustand lagern die federnden Kontaktfinger des Tulpenkontaktstücks auf dem stiftförmigen Gegenkontaktstuck. Im Normalfall wird bei Ausschalten eines solchen Schalters zwischen dem Tulpenkontaktstück und dem ersten Kontaktstück, dem Stiftkontaktstück, ein Lichtbogen gezogen, dessen einer Fußpunkt auf der Innenseite des röhrförmigen Tulpenkontaktstücks stehen kann. Dies ist insbesondere dann der Fall, wenn ein Teil des den Lichtbogen gegebenenfalls umgebenden Löschgases, beispielsweise Schwefelhexafluorid, durch das Innere des Tulpenkontaktstücks abfließt. Das abfließende Löschgas treibt dann den Lichtbogenfußpunkt in das Innere des hohlen Tulpenkontaktstücks hinein.Such circuit breakers are, for example, as high-voltage circuit breakers known in the form of isolating nozzle switches, where a pin-shaped contact piece a tulip-shaped Contact piece faces. In the event of a shutdown the tulip-shaped contact piece by means of a switch drive separated from the pin-shaped contact piece. When switched on store the resilient contact fingers of the tulip contact piece on the pin-shaped counter contact piece. in the The normal case is when such a switch is turned off between the tulip contact piece and the first contact piece, the pin contact piece, an arc drawn, one of which Base on the inside of the tubular tulip contact piece can stand. This is particularly the case if part of the area surrounding the arc, if any Extinguishing gas, such as sulfur hexafluoride, through the Inside of the tulip contact piece drains away. The draining Extinguishing gas then drives the arc base into the inside of the hollow tulip contact piece.
Im Normalfall sind die dem ersten Kontaktstück, also beispielsweise dem stiftförmigen Kontaktstück zugewandten Enden der federnden Kontaktfinger des Tulpenkontaktstücks aus einem abbrandfesten und somit lichtbogenfesten Verbundwerkstoff, z.B. WCu, hergestellt, damit sie dem Lichtbogen möglichst beschädigungsfrei standhalten.Normally they are the first contact piece, for example ends facing the pin-shaped contact piece the resilient contact finger of the tulip contact piece from one erosion-resistant and therefore arc-proof composite material, e.g. WCu, manufactured so that the arc is as damage-free as possible withstand.
Da die Kontaktfinger insgesamt jedoch federnd ausgebildet sein müssen und da die abbrandfesten Kontaktstoffe eine ungenügende Federwirkung aufweisen, besteht der federnde Teil der Kontaktfinger aus einer anderen Legierung. Da dieses Material zwar federelastisch, aber nicht ebenso abbrandfest ist wie die Spitzen der Kontaktfinger, ergibt sich beim Hineinwandern eines Lichtbogenfußpunktes in das Innere des Tulpenkontaktstücks die Gefahr, daß die Kontaktfinger beschädigt werden.However, since the contact fingers are resilient overall must be and because the erosion-resistant contact materials are insufficient Have spring action, there is the resilient part of the Another alloy contact finger. Because this material Although resilient, it is not as resistant to erosion as the tips of the contact fingers result when walking in an arc base into the interior of the Tulip contact piece the risk that the contact fingers to be damaged.
Der vorliegenden Erfindung liegt daher die Aufgabe zugrunde, eine Kontaktanordnung der eingangs genannten Art zu schaffen, die ein dauerhaft lichtbogenfesteres Tulpenkontaktstück aufweist, das dennoch die für einen effektiven Kontaktdruck erforderliche Federwirkung der Kontaktfinger gewährleistet.The present invention is therefore based on the object to create a contact arrangement of the type mentioned at the outset, which has a tulip contact piece that is more resistant to arcing, that is still necessary for an effective contact pressure Spring action of the contact fingers guaranteed.
Die Aufgabe wird erfindungsgemäß gelöst durch einen lichtbogenfesten rohrförmigen, elektrisch leitenden, im Inneren des Tulpenkontaktes angeordneten Einsatz, der relativ zu dem Rohrstück ortsfest angeordnet ist, und die Innenseite der Kontaktfinger in dem radial federnden Bereich wenigstens teilweise überdeckt.The object is achieved by an arc-proof tubular, electrically conductive, inside of the tulip contact arranged insert, which is relative to the Pipe piece is arranged stationary, and the inside of the Contact fingers in the radially resilient area at least partially covered.
Dadurch, daß der Einsatz die Kontaktfinger überdeckt, kann der Lichtbogen mit seinem Fußpunkt lediglich auf der Innenseite des Einsatzes aufsetzen und beschädigt somit die Kontaktfinger nicht. Da der Einsatz selbst aus einem abbrandfesten Material besteht, hält sich die Beschädigung des Einsatzes durch den Lichtbogen in Grenzen. Der Einsatz selbst muß keinerlei Elastizität aufweisen. Die Kontaktfinger können sich beim Einfahren des ersten Kontaktstücks in das Tulpenkontaktstück radial federnd von dem Einsatz abheben.The fact that the insert covers the contact fingers can the arc with its base only on the inside put on the insert and thus damages the contact fingers Not. Because the insert itself is made of a burn-resistant Material is present, the insert will not be damaged through the arc in limits. The mission itself does not have to be elastic. The contact fingers can itself when the first contact piece moves into the tulip contact piece lift radially resiliently from the insert.
Vorteilhaft kann vorgesehen sein, daß der Außendurchmesser des Einsatzes etwa dem Innendurchmesser des Tulpenkontaktstücks entspricht.It can advantageously be provided that the outer diameter of the insert about the inner diameter of the tulip contact piece corresponds.
In diesem Fall besteht beim Ausschaltvorgang kein Spalt oder wenigstens kein großer Spalt, in den der Lichtbogen hineinwandern könnte, zwischen dem Einsatz und den Kontaktstücken.In this case, there is no gap or when switching off at least not a large gap in which the arc could migrate between the mission and the Contact pieces.
Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, daß der Einsatz aus einer Wolfram-Kupfer-Legierung oder aus Graphit besteht.An advantageous embodiment of the invention provides that the use of a tungsten-copper alloy or There is graphite.
Diese Materialien sind besonders lichtbogenfest und genügend leitfähig.These materials are particularly arc-proof and sufficient conductive.
Die Erfindung kann auch vorteilhaft dadurch ausgestaltet sein, daß die Kontaktfinger im wesentlichen aus Kupfer-Chrom-Zirkon bestehen.The invention can also be advantageously configured in this way be that the contact fingers essentially made of copper-chrome-zircon consist.
Diese Legierung ist einerseits federelastisch und gut leitend und läßt sich andererseits einfach und sicher mechanisch mit den Enden der Kontaktfinger verbinden, die aus einem Wolfram-Kupfer-Verbundwerkstoff bestehen. On the one hand, this alloy is resilient and highly conductive and, on the other hand, can be easily and safely mechanically Connect the ends of the contact fingers, which are made of a tungsten-copper composite consist.
Vorteilhaft kann vorgesehen sein, daß die dem ersten Kontaktstück zugewandten Enden der Kontaktfinger aus Wolfram-Kupfer bestehen.It can advantageously be provided that the first contact piece facing ends of the contact fingers made of tungsten copper consist.
Diese Legierung ist sehr lichtbogenfest.This alloy is very resistant to arcing.
Eine vorteilhafte Ausgestaltung der Erfindung sieht weiter vor, daß der Einsatz in einen rohrförmigen Kontaktstückträger eingepreßt ist und seinerseits das Rohrstück trägt.An advantageous embodiment of the invention continues before inserting into a tubular contact piece carrier is pressed and in turn carries the pipe section.
Im folgenden wird die Erfindung anhand eines Ausführungsbeispiels in einer Zeichnung gezeigt und nachfolgend beschrieben.In the following the invention is based on an embodiment shown in a drawing and described below.
