Aus- und Umschalter für große StromstärkenOn and off switch for large currents

Patentiert im Deutschen Reiche vom 3. August 1932 abPatented in the German Empire on August 3, 1932

Die Erfindung bezieht sich auf Aus- und Umschalter, bei denen das Traggerüst aus mit Isolierabdeckung vei'sehenen Flächstäben und den Lagern für die zentral angeordnete Exzenterwelle besteht und durch paarweise Anordnung der Schaltelemente zu seinen Seiten mechanisch !entlastet ist. Nun sind zwar schon derartige Schalter vorgeschlagen worden, bei denen die festen Kontakte, die die Form von Kontaktschienen haben, mittelsi * Laschen und Spannschrauben über zwischenliegende dünne Isolierschichten gegen die Lagerkörper gepreßt werfen. Diese Ausführung, hat aber den Nachteil, daß die Lager für die zentral angeordnete Exzenterwelle! mit den Flachschienen, zu deren Seiten die festen Klontakte angeordnet sind, nicht starr verbunden sind. Vielmehr sind diese Teile nur durch Reibung zusarnrnengehalten, die infolge der Anpressung der stromführenden Kontaktschienen auftritt. Es ist also keim in sich 'einheitliches Traggerüst vorhanden, was den Aufbau des Schalters, besonders bei Bemessung für große Stromstärken, zu wenig 1Ve stabil macht.The invention relates to off and changeover switches in which the support frame consists of flat bars provided with an insulating cover and the bearings for the centrally arranged eccentric shaft and is mechanically relieved by arranging the switching elements in pairs on its sides. Such switches have already been proposed in which the fixed contacts, which are in the form of contact rails, are pressed against the bearing body by means of lugs and clamping screws via thin insulating layers between them. This version, however, has the disadvantage that the bearings for the centrally arranged eccentric shaft! are not rigidly connected to the flat rails, on the sides of which the fixed clone contacts are arranged. Rather, these parts are only held together by friction, which occurs as a result of the pressure on the current-carrying contact rails. It is therefore germ present in itself 'uniform shoring, which makes the structure of the switch, especially at rated for large currents, too little 1 Ve stable.

Erfindungsgemäß wird daher ein stabiles tragfähiges Schaltertraggerüst hergestellt, indem man die, soweit nötig, mit Isolierabdekkung versehenen Flachstäbe, zu. deren Seiten die Schaltelemente paarweise angeordnet sind, und djie Lager für die zentral angeordnete Exzenterwelle unmittelbar durch. Verschrauben fest verbindet. Natürlich, kann statt der Verschraubung eine äquivalente Verbindung stattfinden. Nötigenfalls können auch die Flachstäbe noeh an "ihren Enden oder an weiteren geeigneten, dazwischenliegenden Stellen durch. Querschienen miteinander verstrebt sein.According to the invention, therefore, becomes a stable Load-bearing switch support structure is produced by covering the., if necessary, with an insulating cover provided flat bars, too. the sides of which the switching elements are arranged in pairs, and djie bearings for the centrally located Eccentric shaft through directly. Screw tightly connects. Of course, instead of that Screw an equivalent connection take place. If necessary, the Flat bars either at their ends or at other suitable, intermediate positions. Cross rails braced together be.

In der Zeichnung ist die Erfindung beispielsweise dargestellt, und zwar zeigen Abb. ι und 2 einen Ausschalter in Seitenansicht und im Querschnitt, Abb!. 3 die Verwendung von Verbindungstraversen, die gleichzeitig als Träger des ganzen Schalters ausgebildet sind, wobei Kontaktschienen, Betätigungswelle und Strombrücken der besseren Übersicht halber fortgelassen sind.In the drawing, the invention is shown as an example, namely Fig. Ι and 2 show a circuit breaker in side view and in cross section, Fig !. 3 the use of connecting traverses, which are designed at the same time as carriers of the entire switch, with contact rails, actuating shaft and current bridges being omitted for the sake of clarity.

In der Zeichnung bedeutet α die festen Kontaktschienen oder -platten, gegen die sich 5» in der Sehlüßstellung nach gegenläufiger Bewegung die Strambrücken von außen her pressen, wie dies Abb. 2 erkennen läßt. Mit den Tragschienen b und c sind die Lagerkörper d für die zentral angeordnete Exzenterwelle q mittels Schrauben, h verschraubt. Selbstverständlich kann an Stelle der Verschraubung ein geeignetes anderes Verbindungsmittel benutzt werden. Die festen Kontaktschienen α sind unter Zwischenschaltung von dünnen Isolierschichten, die in der Abbildung durch starke schwarze Linien kennt-In the drawing, α denotes the fixed contact rails or plates, against which the rope bridges are pressed from the outside after moving in opposite directions, as shown in Fig. 2. The bearing bodies d for the centrally arranged eccentric shaft q are screwed to the mounting rails b and c by means of screws, h. Of course, a suitable other connection means can be used instead of the screw connection. The fixed contact rails α are interposed with thin insulating layers, which are identified by strong black lines in the figure.

Handelt es sich um Schalter sehr großer Stromstärken. oder tun Umschalter nut größerer Pol· zahl, so wird man zweckmäßig weitere Verstrebungen, etwa in der Mitte der Schienen b, ö\, vorseli'en oder an sonstigen geeigneten Stellen, u.

The rotation of the eccentric shaft is transmitted in itself. known way by handlebars on the Sehältbrücken. For better stiffening of this supporting structure, the ends of the rails are h f . p. by cross rails / braced together, for example by means of screwing. Is it a switch with very high currents? or if changeover switches only have a larger number of poles, then it is expedient to provide further bracing, for example in the middle of the rails b ,, or at other suitable points, under certain circumstances between each two contact points.

Bei Umschaltern, bei denen die Exzenter-' welle in bekannter Weise axial verschoben, werden soll; wird bei entsprechender Anordnung der Weilenlager d die Antriebswelle; um den. Betrag des Axialschubes verlängert. Die Umschaltung setzt sich, dann: ;aus einer Drehbewegung (Ausschaltung), der Axialverschiebung (Umschaltung) um ungefähr die volle Breite eines Ausschalters und einer Drehbewegung (Einschaltung) zusammen. Bei dieser Art der Umschaltung ergibt sich bekanntlich eine Ersparnis von Kontaktbrücken.With change-over switches in which the eccentric 'shaft is to be axially displaced in a known manner; with the appropriate arrangement of the shaft bearings d the drive shaft; to the.

The switchover consists of:; a rotary movement (switch-off), the axial displacement (switchover) by approximately the full width of a switch and a rotary movement (switch-on). As is known, this type of switching results in a saving of contact bridges.
