Durch das Patent 532 681 ist eine Schaltanordnung zur Erzeugung von Spannungen wechselnder Frequenz, die zur Aufhebung von Induktivitäten insbesondere im Sekun-S därstromkreis von asynchronen Hauptmaschinen dienen, geschützt, die durch eine mittelbar oder unmittelbar in diesen Stromkreis eingeschaltete, mit wechselnder Drehzahl angetriebene Asynchronmaschine, in deren vomThe patent 532,681 discloses a circuit arrangement for generating voltages changing frequency, which is used to cancel inductances, especially in the Sekun-S Därstromkreis of asynchronous main machines are used, protected by an indirect or directly connected to this circuit, driven with alternating speed Asynchronous machine, in whose from

Die kondensatorbelastete asynchrone Hilfsmaschine hat dabei eine doppelte Aufgabe. Zunächst, und zwar durch die Kondensatoren in ihrem Netzfrequenzstromkreis, besorgt sie die Beseitigung der Induktivität ihres Schlupffrequenzstromkreises durch eine ent-The capacitor-loaded asynchronous auxiliary machine has a twofold task. First of all, through the capacitors in her mains frequency circuit, she worries the elimination of the inductance of your slip frequency circuit by means of a dedicated
ao sprechende Gegenspannung und dann die Einführung in ihren Schlupffrequenzstromkreis einer der Netzspannung und der Schlupffrequenz proportionalen Spannung. Diese Spannung hat die Aufgabe, in den Schlupffrequenzstromkreis der asynchronen Haupt- 2S maschine eine zweite (die erste Spannung wird durch die Hauptmaschine selbst erzeugt), der Schlüpfung proportionale, regelbare Spannung einzuführen.ao speaking counter-voltage and then the introduction into your slip frequency circuit of a voltage proportional to the mains voltage and the slip frequency. This voltage has the task, in the slip frequency of the asynchronous main circuit S 2, a second machine (the first voltage is generated by the main engine itself), the slippage proportional to introduce controllable voltage.
Auf dem gleichen Weg, d. h. über 3<> die kondensatorbelastete, asynchrone Hilfsmaschine, ist es nun möglich, auch andere Spannungen in den Schlupffrequenzstromkreis dieser Maschine einzuführen. Man braucht bloß die gewünschten Spannungen in den Kondensatorstromkreis der asynchronen Hilfsmaschine einzuführen, indem man beispielsweise die sämtlichen Stromkreise, in welchen die genannten Spannungen induziert werden, in Reihe schaltet. Dadurch erfährt 4< > die kondensatorbelastete Hilfsmaschine eine Erweiterung ihres Aufgabenkreises, die Gegenstand vorliegender Erfindung ist.In the same way, i. H. via 3 <> the capacitor-loaded, asynchronous auxiliary machine, it is now possible to introduce other voltages into the slip frequency circuit of this machine. Man just needs the desired voltages in the capacitor circuit of the asynchronous Introduce auxiliary machine by, for example, all circuits in which the said voltages are induced, connected in series. This tells 4 < > the capacitor-loaded auxiliary machine an extension of its range of tasks, the The present invention is.
Man kann beispielsweise dem Netz- (Primär-) Stromkreis der asynchronen Hilfsmaschine eine Spannung zuführen, die dem Primärstrome der Hauptmaschine proportional ist. Diese Spannung wird gewonnenOne can, for example, the network (primary) circuit of the asynchronous auxiliary machine Apply a voltage proportional to the primary machine current. This tension is gained
durch einen Transformator 9, dessen Primärwicklung im Netzstromkreis der Hauptmaschine und dessen Sekundärspannung im Netz- (Primär-) Stromkreis V der asynchro-S nen Hilfsmaschine liegen. Der Transformator 9 muß dabei möglichst rückwirkungslos gebaut sein, damit er die Induktivität jenes Stromkreises, in welchem seine Sekundärwicklung eingeschaltet ist, möglichst wenig erhöht. Dieser Transformator, der wegen seiner Rückwirkungslosigkeit zweckmäßigerweise als Stromspannungstransformator bezeichnet wird, kann auch als Drehtransformator ausgeführt werden. Es ist dann besonders leicht, die erforderliche Phase der erzeugten Spannung einzustellen. Durch diesen Stromspannungstransformator 9 wird im Schlupffrequenzstromkreis IV der asynchronen Hilfsmaschine 5 eine Spannung erzeugt, die dem Primärstrom der Hauptmaschine und der Schlüpfung proportional ist. Diese Spannung hat einen Strom zur Folge, der befähigt ist, die störenden Einflüsse der mit der Schlüpfung veränderlichen Induktivität des Sekundärstromkreises II der Hauptmaschine und der veränderlichen Drehzahl der Schlupfmaschinen 2 zu beseitigen.by a transformer 9, the primary winding of which is in the mains circuit of the main machine and whose secondary voltage is in the mains (primary) circuit V of the asynchronous S NEN auxiliary machine. The transformer 9 must be built as reactionless as possible, so that it reduces the inductance of that Circuit in which its secondary winding is switched on, as little as possible elevated. This transformer, which is expedient because of its ineffectiveness is referred to as a voltage transformer, can also be called a rotary transformer are executed. It is then particularly easy to set the required phase of the generated voltage. Through this Voltage transformer 9 is in the slip frequency circuit IV of the asynchronous Auxiliary machine 5 generates a voltage that corresponds to the primary current of the main machine and is proportional to the hatch. This voltage results in a current that is able to withstand the disruptive influences of the the slip variable inductance of the secondary circuit II of the main engine and the variable speed of the slip machines 2 to eliminate.
Als zweites Beispiel sei die Einführung der Sekundär spannung eines Stromspannungstransformator 10 in dem Netz- (Primär-) Stromkreis der asynchronen Hilfsmaschine 5 angeführt. Der Stromspannungstransformator 10 ist primär in den Erregerstromkreis III der Schlupfmaschinen 2 eingeschaltet. Er erzeugt, wenn er passend mittelbar oder unmittelbar von der Welle der Hauptmaschine angetrieben wird, in seiner Sekundärwicklung eine Spannung der Netzfrequenz, die seinem Primärstfom proportional ist. Diese Spannung wird wiederum durch die kondensatorbelastete asynchrone Hilfsmaschine in eine der Schlüpfung proportionale Spannung im Stromkreise IV übergeführt. Seine Aufgabe ist bezüglich des Stromkreises III die gleiche wie die des Transformators 9 bezüglich des Stromkreises II.The second example is the introduction of the secondary voltage of a voltage transformer 10 in the network (primary) circuit of the asynchronous auxiliary machine 5 cited. The voltage transformer 10 is primarily in the excitation circuit III of the slip machines 2 switched on. It is generated when it fits directly or indirectly from the shaft of the main engine is driven, a voltage of the mains frequency in its secondary winding, which is proportional to its primary current. This tension is in turn due to the capacitor-loaded asynchronous auxiliary machine into one proportional to the slip Voltage transferred in circuit IV. With regard to circuit III, its task is the same as that of the Transformer 9 with respect to circuit II.
In ganz ähnlicher Weise könnte man an Stelle des ruhenden Stromspannungstransformators 10 des Patents 532 681 einen rotierenden Stromspannungstransformator 11 anordnen, dessen Sekundärwicklung dann in den Primärstromkreis V der asynchronen, kondensatorbelasteten Hilfsmaschine 5 einzuschalten wäre. Die Schaltung seiner Primärwicklung würde sich dagegen nicht ändern. Seine· Primärwicklung läge, wie in der Abbildung gezeichnet, über einem induktionslosen Widerstand 12 an den Klemmen der Erregermaschinen 3. Er hat in allen Fällen die Aufgabe, entweder unmittelbar oder mittelbar in den Schlupffrequenzstromkreis IV eine Spannung einzuführen, die der Schlüpfung und der Spannung der Erregermaschine 3 proportional ist.In a very similar way one could instead of the static voltage transformer 10 of patent 532,681 a rotating Arrange voltage transformer 11, the secondary winding then in to switch on the primary circuit V of the asynchronous, capacitor-loaded auxiliary machine 5 were. The circuit of its primary winding, however, would not change. Its primary winding would be as in drawn in the figure, over a non-inductive resistor 12 at the terminals of the excitation machines 3. In all cases it has the task, either directly or to introduce a voltage indirectly into the slip frequency circuit IV, which the Slip and the voltage of the exciter 3 is proportional.
Wie erwähnt," müssen die Spannungen, die rotierende Transformatoren dieser Art dem Netzstromkreis der asynchronen Hilfsmaschine zuführen, bestimmte Phasenwinkel bezüglich der sie hervorrufenden Ströme aufweisen. Dies läßt sich dadurch erreichen, daß man die rotierenden Transformatoren mit verdrehbaren primären oder sekundären Stromkreisen versieht.As mentioned, "the voltages used by rotating transformers of this type Feed certain phase angles to the mains circuit of the asynchronous auxiliary machine with respect to the currents that cause them. This can be achieved by that the rotating transformers with rotatable primary or secondary Circuits.
