Description

#9843# 9843

Gegenstand des Hauptpatents ist ein Trennschalter für Hochspannungsfreileitungen, bei welchen die Kontaktstücke sich am unteren Ende von Hängeisolatoren befinden, die an einem heb- und senkbaren Träger aufgehängt und mit Lenkern verbunden sind. Zum Öffnen und Schließen des Schalters wird der Träger der Hängeisolatoren gehoben bzw. gesenkt, und es werden dabei die Kontaktstücke infolge der Wirkung der Lenker voneinander getrennt bzw. einander genähert und ineinandergeschoben. Die Lenker verbinden den unteren Teil der Hängeisolatoren mit den Abspannisolatoren und sind an beiden gelenkig angeschlossen.The subject of the main patent is a disconnector for high-voltage overhead lines, in which the contact pieces are at the lower end of suspension insulators, which are suspended from a carrier that can be raised and lowered and connected to handlebars. To open and close the switch, the support of the suspension insulators is lifted or lowered, and there are thereby the contact pieces as a result of the action of the handlebars separated from one another or approached and pushed into one another. The links connect the lower part of the suspension isolators with the tension insulators and are articulated to both.

Wenn das obere Ende der Lenkstange unmittelbar mittels eines Gelenkes am Abspannisolator befestigt ist, kann ein Schwingen der Spanndrähte gegebenenfalls einen Einfluß auf den Schalter ausüben. Die Erfindung betrifft eine Verbesserung des Freileitungsschalters, durch welche dieser Übelstand beseitigt wird. Nach der Erfindung werden die Lenker so ausschwenkbar mit «5 Jen Spanndrähten bzw. mit den Abspannisolatoren verbunden, daß sie nicht nur ausschwenken, sondern sich auch in ihrer°Längsrichtung, also quer zu den Spanndrähten., verschieben können. Die Verschiebbarkeit kann z. B. dadurch herbeigeführt werden, daß die Lenker am oberen Ende schleifenförmige Bügel tragen, in welche die Verbindungsteile der Hängeisolatoren eingreifen. Bei geschlossenem Schalter stehen die Lenker dann auf den Kontaktstiicfcen, und ein Schwenken der Spanndrähte hat auf den Schalter keinen Einfluß, weil eine Relativverschiebung zwischen der Verspannung und den Lenkern möglich ist.When the upper end of the handlebar is directly connected to the guy insulator by means of a joint is attached, an oscillation of the tension wires can possibly have an influence on the switch. The invention concerns an improvement of the overhead line switch, through which this drawback is eliminated. According to the invention, the handlebars can be swung out with «5 Jen tensioning wires or with the tensioning insulators connected that they not only swing out, but also in their ° longitudinal direction, so across the tension wires., can move. The movability can e.g. B. be brought about that the handlebars loop-shaped at the top Wear brackets in which the connecting parts of the suspension insulators engage. When the switch is closed, the handlebars are stationary then on the Kontaktstiicfcen, and a Pivoting the tension wires has no influence on the switch, because a relative displacement between the bracing and the handlebars is possible.

Die Leitungen α sind durch die Stabisolatoren α und c gegen den Träger d eines Mastes o. dgl. abgespannt. Die abgespannte Leitung wird von der Klemme e . an dem Lenker/ entlang zu dem Kontaktstückg bzw. h geführt. Die Lenker / und die mit ihnen starr verbundenen Kontaktstückeg, h sind an ihren unteren Enden gelenkig mit den Hängeisolatoren i, k verbunden, die an der in senkrechter Richtung beweglichen Schiene I aufgehängt sind. Durch Nachlassen bzw. Anziehen der Seile m und η wird die Schiene I gesenkt oder gehoben und dadurch der Kontakt geöffnet bzw. geschlossen. Nach der Erfindung ist der Lenker / nicht direkt an dem Abspannisolator, sondern an dem Zwischenstück 0, das mit einem länglichen Schlitz über einen Bolzen p des Gliedes q greift, befestigt. Bei etwaigem Schwingen der Leitung α und des Abspannisolators kann der Bolzen p sich in dem länglichen Schlitz des Zwischenstückes 0 auf und ab bewegen. Der Lenker/ bleibt also in Ruhe, und die Kontaktteile g und h bleiben unbeansprucht. The lines α are braced against the support d of a mast or the like by the rod insulators α and c. The tensioned line is connected to the terminal e . guided on the handlebar / along to the contact piece g or h. The links / and the contact pieces g, h rigidly connected to them are articulated at their lower ends to the suspension insulators i, k , which are suspended from the rail I, which is movable in the vertical direction. By slackening or tightening the ropes m and η , the rail I is lowered or raised and the contact is thereby opened or closed. According to the invention, the link / is not attached directly to the guy insulator, but to the intermediate piece 0, which engages with an elongated slot over a bolt p of the link q. If the line α and the tensioning insulator vibrate, the bolt p can move up and down in the elongated slot of the intermediate piece 0. The handlebar / remains at rest, and the contact parts g and h remain unstressed.
