Description

Die Trennschalter sind in Hochspannungsanlagen diejenigen Stellen, an denen betriebsmäßig die höchsten Spannungen auftreten. Ist der Trennschalter ausgeschaltet, so können die Leitungen sowohl vor wie hinter dem Trennschalter die betriebsmäßige Spannung führen, derart, daß zwischen den Trennschalterkontakten eine Beanspruchung mit doppelter Betriebsspannung vorhanden ist, ganz abgesehen von Überspannungen!, die diese Beanspruchung noch erhöhen. Man hat deshalb zur Erhöhung der Sicherheit Doppeltrennschalter angewendet, die in jeder Phase drei Isolatoren enthalten, je einen für die ankommende und die abgehende Leitung und einen mittleren Isolator zum Tragen und Betätigen des Trennmessers. Dabei ist es üblich geworden, den1 mittleren Isolator um seine Achse zu drehen und so das Trennmesser aus der durch Isolatorachse und Leitungs- ao richtung bestimmten1 Ebene seitlich herauszudrehen. Dadurch wird der Abstand von Phase zu.Phase vermindert und die Sicherheit gerade an der gefährlichsten Stelle der Schaltanlage herabgesetzt. Um diese Gefahr nicht zu groß werden zu lassen, hat man dien Phasenabstand vergrößert, wodurch sich der Raumbedarf und die Baukosten der Schaltanlage wesentlich erhöhen. Mit Hilfe der Erfindung werden diese Nachteile beseitigt und die Betriebssicherheit der Schaltanlagen an den am meisten beanspruchten Punkten vergrößert. In high-voltage systems, the disconnectors are those points where the highest voltages occur during operation. If the disconnector is switched off, the lines in front of as well as behind the disconnector can carry the operational voltage in such a way that there is a stress with double the operating voltage between the disconnector contacts, quite apart from overvoltages !, which increase this stress even more. To increase safety, double disconnectors have therefore been used which contain three insulators in each phase, one for the incoming and one for the outgoing line and a central insulator for carrying and operating the cutting blade. It has become customary to turn the 1 middle insulator around its axis and thus to turn the cutting knife laterally out of the 1 plane determined by the insulator axis and line direction. This reduces the phase-to-phase distance and reduces safety, especially at the most dangerous point in the switchgear. In order not to let this risk become too great, the phase spacing has been increased, which significantly increases the space requirement and the construction costs of the switchgear. With the help of the invention, these disadvantages are eliminated and the operational reliability of the switchgear is increased at the most stressed points.
