elektrischer Schwingungen.electrical vibrations.
Patentiert im Deutschen Reiche vom 19. Oktober 1910 ab.Patented in the German Empire on October 19, 1910.
Die Erfindung betrifft eine Anordnung, zur Unterbrechung von Gleichstrom, insbesondere zur Erzeugung elektrischer Schwingungen, bei welcher die Unterbrechung mittels Kollektoren erfolgt; der beim Erfindungsgegenstand erstrebte Zweck besteht darin, die Lichtbogenbildung, zu verringern und die zulässige Spannung und Betriebsdauer der Anlage zu steigern. The invention relates to an arrangement for interrupting direct current, in particular to generate electrical vibrations, in which the interruption by means of collectors he follows; the purpose pursued with the subject matter of the invention is to prevent arcing, to reduce and to increase the permissible voltage and operating time of the system.
ίο Es sind schon Anordnungen zur Erzeugung elektrischer Schwingungen mittels unterbrochenen Gleichstroms bekannt, bei denen ein Gleichstromkollektor als Unterbrecher benutzt wird. Der Verwendnng dieser Anordnung ist jedoch durch die Höhe der zulässigen Spannung eine Grenze gesetzt, indem von einer gewissen Spannung ab die Funkenbildung - so stark wird, daß die Kontaktteile zerstört werden und die Unterbrechung nicht mehr richtig erfolgt.ίο There are already orders for generation electrical oscillations by means of interrupted direct current known, in which a direct current collector is used as a breaker. The use of this arrangement is, however, due to the level of the allowable voltage The limit is set by sparking from a certain voltage - so strong, that the contact parts are destroyed and the interruption no longer takes place correctly.
Diese Nachteile werden durch die vorliegende Erfindung dadurch beseitigt, daß mehrere Kollektoren benutzt werden, die in den zu unterbrechenden Stromkreis derart hintereinandergeschaltet werden, daß die zusammengehörigen Unterbrechungen synchron oder nahezu synchron erfolgen.These disadvantages are eliminated by the present invention in that several Collectors are used that are connected in series in the circuit to be interrupted that the related interruptions occur synchronously or almost synchronously.
Es kommt dann auf jede Unterbrechungsstelle nur ein Teil der Gesamtspannung, so daß bei einer entsprechenden Anzahl hintereinandergeschalteter Kollektoren jede beliebig hohe Spannung ohne Schaden unterbrochen werden kann.Only a part of the total voltage then comes to each interruption point, like this that with a corresponding number of collectors connected in series, any one high voltage can be interrupted without damage.
Auf der beiliegenden Zeichnung ist diese Anordnung beispielsweise veranschaulicht. Jeder Kollektor 2 ist mit einem Schleifring 5 verbunden. Die Zuführung des Stromes zu den Kollektoren erfolgt durch Bürsten 3, die Ableitung durch die Bürsten 6 auf den Schleifringen 5.This arrangement is illustrated, for example, in the accompanying drawing. Everyone Collector 2 is connected to a slip ring 5. The supply of electricity to the Collectors are carried out by brushes 3, the discharge by brushes 6 on the slip rings 5.
Sämtliche Kollektoren sind derart hintereinandergeschaltet, daß der Übergang von jeder Bürste 3 auf ihren Kollektor 2 an allen Berührungsstellen in derselben Richtung erfolgt, so daß sämtliche Bürsten einerseits und die Kollektoren andererseits die gleiche Polaritat besitzen. Hierdurch wird ein ungleichmäßiges Abbrennen der Bürsten verhindert.All collectors are connected in series in such a way that that the transition from each brush 3 to its collector 2 takes place in the same direction at all contact points, so that all the brushes on the one hand and the collectors on the other hand have the same polarity own. This prevents the brushes from burning unevenly.
Außerdem hat sich herausgestellt, daß, wenn man die Bürsten als· Kathode anordnet, d. h. also, wenn die positive Stromrichtung stets vom Kollektor nach der Bürste zu verläuft, der Kollektor schneller zerstört wird als die Bürste, und daß umgekehrt die Bürste schneller abbrennt, dafür aber der Kollektor bedeutend länger betriebsfähig bleibt, wenn man die Bürsten als Anode ausbildet. Demgemäß besteht die weitere Erfindung darin, daß die Polarität so gewählt ist, daß von den beiden Elektroden die Bürste schneller abbrennt, da diese leicht ausgewechselt werden kann.It has also been found that when the brushes are arranged as a cathode, i. H. So if the positive current direction always runs from the collector to the brush, the Collector is destroyed faster than the brush, and that conversely the brush burns off faster, but the collector remains operational significantly longer if you use the Brushes trained as an anode. Accordingly, the further invention is that the The polarity is chosen so that the brush burns off faster of the two electrodes because this can be easily replaced.
