Den Gegenstand vorliegender Erfindung bildet ein Hochspannungsausschalter, bei dessen Bauart hauptsächlich darauf Rücksicht genommen wurde, seine Raumverhältnissc möglichst zu verkleinern und namentlich die bei den bekannten Hochspannungsschaltern grofse Ausschlagwinkel der Schalthebel zu vermeiden.The subject of the present invention forms a high-voltage circuit breaker, in which Design was mainly taken into account, its spatial proportions as possible to be reduced in size and, in particular, that of the known high-voltage switches to be larger Avoid deflection angle of the gear lever.
Der Ausschalter, welcher sowohl ein- als mehrpolig ausgeführt werden kann, hat Kabelanschlüsse, wie dies allgemein üblich, an den Stromschlufstheilen b b und c c. Die stromunterbrechenden Theile des Ausschalters bestehen je nach der Netzspannung aus zwei oder mehr teleskopartig in einander verschiebbaren Metallrohren n, so dafs bei vollständig in einander geschobenen Rohren die Länge des beweglichen Stromleiters nur einhalb bis einviertel der Gesammtlä'nge des stromleitenden Metallrohres beträgt. Die Stromunterbrechung ■ des Ausschalters erfolgt selbsttätig durch eine im Innern des Rohres angeordnete eng gewickelte Schraubenfeder p. The circuit breaker, which can be designed with one or more poles, has cable connections, as is generally the case, at the power circuit parts bb and c c. The current-interrupting parts of the circuit breaker consist, depending on the mains voltage, of two or more telescopically displaceable metal tubes n, so that when the tubes are completely pushed into each other, the length of the movable conductor is only one-half to one-quarter of the total length of the current-conducting metal tube. The current interruption ■ of the circuit breaker takes place automatically by means of a tightly wound coil spring p arranged inside the tube.
Mittelst des Knopfes g, welcher in der Mitte des die beiden Ro.hrsysteme η verbindenden Isolirstückes f befestigt ist, werden die Federn ρ beim Ausziehen der Stromleitern ti gespannt, worauf die beiden messerartig ausgebildeten Polstücke m m zwischen die an den festliegenden StromschlufsstUcken c c angeordneten Blattfedern e e eintreten und in dieser Stellung durch Einspringen der an der Feder d befestigten Stahlnase Z festgehalten "werden. Die Wirkungsweise des Schalters ist ohne Weiteres verständlich. : .In the middle of the button g, which is fastened in the middle of the insulating piece f connecting the two pipe systems η , the springs ρ are tensioned when the current conductors ti are pulled out, whereupon the two knife-like pole pieces mm between the leaf springs ee arranged on the fixed electrical connection pieces cc enter and are held in this position by jumping in the steel nose Z attached to the spring d ". The mode of operation of the switch is readily understandable. : .
Durch Druck auf den Knopf r der Feder d, die an der Unterseite des Sockels α angebracht ist, wird die Nase / frei gegeben und die Feder ρ unterbricht sofort den Stromkreis durch Ineinanderziehen der Rohre η η. By pressing the button r of the spring d, which is attached to the underside of the base α , the nose / is released and the spring ρ immediately interrupts the circuit by pulling the tubes η η into one another.
Dieselben sind so genau in einander gepal'st, dafs noch' besondere Ventilöffnungen q q vorgesehen werden müssen, durch welche die beim Ineinanderschieben der teleskopartigen Rohre zusammengeprefste Luft entweichen kann. Durch Aenderung der Oeffnungsdurchmesser von q q Iä'fst sich die Geschwindigkeit der Bewegung von η η vollkommen in weiten Grenzen regeln.They are so closely packed together that special valve openings qq have to be provided through which the air compressed when the telescopic tubes are pushed into one another can escape. By changing the opening diameter of qq I, the speed of movement of η η can be regulated completely within wide limits.
Die Länge der Funkenstrecke wird, aufser durch die Anzahl der Rohrstücke, noch durch Verschiebung der ersten mit Gewinde versehenen Rohre 0 geregelt.The length of the spark gap is determined by the number of pipe sections Displacement of the first threaded pipes 0 regulated.
An Stelle der teleskopartig in einander verschiebbaren Rohre kann auch jede andere Anordnung treten, welche ein geradliniges Zusammenschieben der einzelnen Theile des beweglichen Schaltstücks gestattet, was auch durch kulissenartig in einander verschiebbare Platten u. dergl. erreicht werden kann.Instead of the tubes which can be telescoped into one another, any other arrangement can also be used occur, which push the individual parts of the movable one together in a straight line Switching piece permitted, which can also be shifted into one another like a backdrop Plates and the like can be achieved.
