Description

Die Erfindung betrifft eine Schaltungsanordnung zur Parallelschaltung von Hochfrequenzwechselstrommaschinen, mit welcher der Zweck verfolgt wird, die synchronisierende Kraft zu erhöhen und zu regeln.The invention relates to a circuit arrangement for the parallel connection of high-frequency AC machines, with which the purpose is pursued to increase and regulate the synchronizing force.

Zu diesem Zweck sind schon Schaltungsanordnungen vorgeschlagen worden, bei denen Kondensatoren vorgesehen sind, um sich dem von Hopkinson bestimmtenCircuit arrangements have already been proposed for this purpose at which capacitors are provided to conform to that determined by Hopkinson

»ο Kopplungsoptimum möglichst zu nähern (deutsche Patentschrift 337849).»Ο as close as possible to the optimum coupling (German patent 337849).

Gegenüber der bekannten Schaltungsanordnung besitzt die erfindungsgemäße die wichtigen Vorteile, daß einerseits durch die Kondensatoren nur der synchronisierende Strom fließt, so daß die von ihnen verlangte Arbeit viel geringer und anderseits die Regelung der synchronisierenden Kraft unabhängig· von der Einstellung der NutzbelastungCompared to the known circuit arrangement according to the invention has the important advantages that, on the one hand, only the synchronizing due to the capacitors Current flows so that the work required of them is much less and the other hand the regulation of the synchronizing force independent of the setting of the useful load

ao der einzelnen Wechselstromerzeuger erfolgen kann. Hieraus folgt, daß diese Regelung außerordentlich einfach wird, da sie insbesondere unabhängig von der üblichen Resonanzeinstellung des Belastungskreises wird, welcher aus den gekoppelten Wechselstromerzeugern und dem Verbrauchsapparat (Antenne usw.) gebildet ist.ao of the individual alternator can be done. It follows that this regulation It is extremely simple, since it is particularly independent of the usual resonance setting of the load circuit, which consists of the coupled alternators and the consumer apparatus (antenna etc.) is formed.

Auf der Zeichnung ist eine beispielsweise Ausführungsform einer Schaltungsanordnung gemäß der Erfindung veranschaulicht.The drawing shows an exemplary embodiment of a circuit arrangement illustrated according to the invention.

Die beiden Hochfrequenzwechselstromerzeuger ι und 2 dienen zur unmittelbaren Speisung der Antenne 3. Einer ihrer Pole ist an die Masse 4 angeschlossen, und beide Wechselstromerzeuger sind miteinander gekoppelt durch eine Selbstinduktionsspule 5, deren Mittelpunkt an die Antenne 3 angeschlossen ist. Zwischen die Klemmen der Selbstinduktionsspule ist ein Kopplungskondensator 6 geschaltet, mit dem gegebenenfalls in Reihe ein Regelungsvariometer 7 angeordnet ist.The two high-frequency alternators ι and 2 are used for immediate Feeding antenna 3. One of its poles is connected to ground 4, and both AC generators are coupled to one another by a self-induction coil 5, the center of which is connected to the antenna 3. There is a coupling capacitor between the terminals of the self-induction coil 6 switched, with which a control variometer 7 may be arranged in series is.

Man kann sich leicht davon überzeugen, daß der Kondensator nur durch den synchronisierenden Strom durchflossen wird, der übrigens mittels des Variometers 7 auf den passendsten Wert eingestellt werden kann.One can easily convince oneself that the capacitor is only controlled by the synchronizing Current flows through which, by the way, can be set to the most suitable value by means of the variometer 7.

Sind des weiteren die magnetischen Streuungen zwischen den beiden Teilen der Spule ς sehr klein, so übt das Gebildes, 6 in praktischer Hinsicht überhaupt keinen zu berücksichtigenden Einfluß auf die Regelung der Nutzleistung in der Antenne 3 aus, da die dieser Leistung entsprechenden resultierenden Amperewindungen gleich Null sind. Die Spule 5 kann gegebenenfalls durch zwei in Reihe geschaltete Induktanzen oder Kapazitäten ersetzt werden, wobei der Verbindungspunkt zwischen beiden an die Antenne 3 angeschlossen wird. In diesem Falle übt das System jedoch einen gewissen Einfluß auf die Regelung der Nutzleistung aus. Die Einstellung des synchronisierenden Stromes kann j edoch immer noch unabhängig mittels des Gebildes 6, 7 erfolgen.Are also the magnetic scatter between the two parts of the Coil ς very small, so the structure exercises, 6 in from a practical point of view no influence at all to be taken into account on the regulation the useful power in the antenna 3, since the resulting power corresponding to this Ampere turns are zero. The coil 5 can optionally by two Series-connected inductances or capacitances are replaced, with the connection point is connected to the antenna 3 between the two. In this case, however, the system has some influence on the regulation of the useful power. However, the setting of the synchronizing current can still be done independently take place by means of the structure 6, 7.

Selbstverständlich läßt diese Schaltungsanordnung zahlreiche Varianten zu. So kann z. B. die Verbindung zwischen dem Wechselstromerzeuger und der Antenne anstatt unmittelbar, wie in der Abbildung angegeben, über einen Transformator erfolgen. Die Schaltungsanordnung ist gleichfalls anwendbar, wenn mehrere Wechselstromerzeuger vorgesehen sind.Of course, this circuit arrangement allows numerous variants. So can e.g. B. the connection between the alternator and the antenna instead directly, as indicated in the figure, via a transformer. The circuit arrangement can also be used, if several alternators are provided.
