Description
Trennschalter für Hoch- und Höchstspannungsschaltanlagen Die Erfindung betrifft einen Trennschalter für Hoch- und Höchstspannungsschaltanlagen, dessen Gegenkontakt nicht an einem gegenüber dem Trennmesser fixierten Isolator, sondern unmittelbar an der Freileitung oder Sammelschiene, mit der die Verbindung hergestellt werden soll, befestigt ist. Bisher hat man für Schaltanlagen mit an Leitungen angebrachten Gegenkontakten Hebeltrennschalter mit entsprechend langen Trennmessern vorgesehen. Die Trennmesser waren schneidenförmig für den Einschlag in U-förmige, federnde Gegenkontakte ausgebildet. Um ein sicheres Einschalten zu erreichen, mußten die Freileitungen durch besondere Verschalungen versteift werden.Disconnectors for high and extra high voltage switchgear The invention relates to a disconnector for high and extra high voltage switchgear, its The mating contact is not on an insulator that is fixed opposite the cutting knife, but rather directly on the overhead line or busbar with which the connection is made is to be attached. So far one has for switchgear with attached to lines Counter-contacts lever disconnector with correspondingly long disconnecting knives provided. The cutting knives were knife-edge for impact in U-shaped, resilient mating contacts educated. In order to achieve a safe switch-on, the overhead lines had to be stiffened by special cladding.
Demgegenüber geht die Erfindung von der AuEfgabe aus, eine sichere Verbindung zwischen dem Trennschalter und der Freileitung oder einem mit dieser verbundenen Gegenkontakt herzustellen, ohne daß besondere Maßnahmen ZUf Versteifung der Freileitung notwendig sind. Erfindungsgemäß ist zu diesem Zweck zwischen Trennmesser und Gegenkontakt in der Einschaltstellung eine von dem Trennmesser ausgelöste oder ausgeübte Greif- oder Klemmverbindung vorgesehen. Als solche Greif-oder Klemmverbindungen können alle in der Technik bekannten Maßnahmen benutzt werden. Mit ihrer Hilfe läßt sich der Gegenkontakt stets sicher erfassen und eine gute Kontaktgabe herstellen, ohne daß eine starke mechanische Kraft hierbei auf die Freileitung einwirkt. In contrast, the invention is based on the task, a safe one Connection between the disconnector and the overhead line or one with this Establish connected mating contact without special measures ZUf stiffening the overhead line are necessary. According to the invention is for this purpose between the cutting knife and mating contact in the switched-on position one triggered by the separating knife or exercised gripping or clamping connection provided. As such, gripping or clamping connections all measures known in the art can be used. With their help lets the opposing contact always grasp reliably and establish good contact, without a strong mechanical force acting on the overhead line.
Damit die Greif- oder Klemmverbindung im eingeschalteten Zustand entlastet ist, wird ferner zweckmäßig eine selbsttätig wirkende Sperrung angeordnet, die durch die letzte Schaltbewegung aus- gelöst wird. Außerdem kann eine z. B. trichterförmige Führungsvorrichtung am Trennmesser oder am Gegenkontakt angebracht sein, die das-Trennmesser sicher an den Gegenkontakt heranführt. So that the gripping or clamping connection is switched on is relieved, an automatically acting lock is also expediently arranged, which were selected by the last switching movement is resolved. Also can a z. B. funnel-shaped guide device on the cutting knife or on the mating contact be attached, which brings the cutting knife safely to the mating contact.
Zur Auslösung der Greif- oder Klemmverbindung bzw. ihrer Sperrung genügt in der Regel der Druck, der durch das Gewicht oder die Verspannung der Leitung, an der sich der Gegenkontakt befindet, ausgeübt wird. Um mit möglichst kleinen Kräften auszukommen, kann man die Ans lösung auch über einen Fühler steuern. To release the grip or clamp connection or to block it As a rule, the pressure generated by the weight or tension of the line is sufficient. where the mating contact is located. To do it with as little strength as possible the solution can also be controlled via a sensor.
Die Greifwirkung kann sowohl von dem Trennmesser als auch von einer am Gegenkontakt angebrachten Vorrichtung ausgeübt werden: Die zweite Art eignet sich besonders als geschützte Ausführung, wenn der Gegenkontakt oberhalb des Trennmessers bzw. des Trennschalterstützers angebracht ist. The gripping effect can both from the cutting knife and from a device attached to the mating contact: The second type is suitable especially as a protected version if the mating contact is above the cutting knife or the disconnector support is attached.
