PATENTAMT.PATENT OFFICE.
Der in dem Hauptpatent 208260 sowie in dem Zusatzpatent 208551 beschriebene Hochfrequenzgenerator kann dadurch verbessert werden, daß man von der bei gewöhnlichen Wechselstromgeneratoren wohlbekannten Erregung durch einen voreilenden Ankerstrom Gebrauch macht.The high-frequency generator described in the main patent 208260 and in the additional patent 208551 can be improved by removing the excitation well known in ordinary alternators makes use of a leading armature current.
Arbeitet ein Wechselstromgenerator auf einen Kreis, der mit Kapazität behaftet ist oder übererregte Synchronmaschinen enthält, so kann der Strom zu einem voreilenden werden und eine Spannungssteigerung hervorrufen. Während ein »nacheilender« Strom »entmagnetisiert« (induktive Belastung), »magnetisiert« der voreilende Strom. Es ist auch möglich, die Erregung vollkommen zu entfernen und die Maschine ganz durch voreilenden Ankerstrom erregen zu lassen.An alternator works on a circuit that has capacity or contains overexcited synchronous machines, the current can become a leading one and cause an increase in tension. While a "lagging" current "demagnetizes" (inductive load), the leading current »magnetizes«. It is also possible, to remove the excitation completely and the machine entirely by leading armature current to get excited.
Von dieser bekannten Erscheinung soll auch bei dem Hochfrequenzgenerator Gebrauch gemacht werden. Dies kann hier um so leichter geschehen, weil von vornherein Abstimmungselemente vorgesehen sind, die Kapazität enthalten, und die Belastung durch eine Antenne an und für sich einer Kapazitätsbelastung gleichkommt.Use should also be made of this known phenomenon in the case of the high-frequency generator will. This can be all the easier here because coordination elements are provided from the outset that contain capacity, and the load from an antenna is in and of itself equivalent to a capacity load.
Andererseits kann der voreilende wattlose Strom auch einer Vorrichtung zur Erzeugung hochfrequenter Ströme, z. B. einer Bogenlampe, entnommen werden, die mit dem Generator zusammen auf den Nutzkreis arbeitet und hier die Rolle einer übererregten Synchronmaschine spielt. Diese Anordnung ist in der Figur dargestellt. Es bedeutet G, G einen Doppelgenerator nach Zusatzpatent 208551, A,A,A Abstimmungskreise und B die Bogenlampe.On the other hand, the leading wattless current can also be used in a device for generating high-frequency currents, e.g. B. an arc lamp, which works with the generator on the useful circuit and here plays the role of an overexcited synchronous machine. This arrangement is shown in the figure. It means G, G a double generator according to additional patent 208551, A, A, A voting circles and B the arc lamp.
Der Vorteil, den eine solche Anordnung bietet, liegt darin, daß eine größere Unabhängigkeit von der Erregung erzielt wird (event. Fortfall der Gleichstrom- oder Wechselstromerregung). Auch kann die Zahl der Abstimmungskreise A und Energieumsetzungen verringert werden, weil es nicht nötig ist, die niedrigeren Frequenzen in Erscheinung treten zu lassen.The advantage offered by such an arrangement is that greater independence from the excitation is achieved (possible omission of direct current or alternating current excitation). The number of tuning circles A and energy conversions can also be reduced because it is not necessary to let the lower frequencies appear.
