Description
Anordnung zum Tasten bei Hochfrequenzanlageti mit statischen Frequenzwandlern Im Hauptpatent ist eine Tastmethode angegeben, bei der das Verhältnis des Ma-Nchinenkreiswiderstandes tv, zu dem Kopplungswiderstand w, dem absoluten Betrage nach so groß gewählt ist, daß die Anlage bei normaler Erregung und Drehzahl der Maschine bloß durch Schließen des Schalters zwis'c'hen Maschine und Anlage ohne weiteres in Tätigkeit kommen kann und das Tasten durch Änderung dieses Verhältnisses erfolgt. Die angestellten Untersuchungen haben nun gezeigt, daß man die Tastempfindlichkeit dieser Methode noch bedeutend steigern kann, wenn man nach der vorliegenden Erfindung den Widerstand iv, aus in, zwei oder mehreren Maschen liegenden Teilen bildet und m einer dieser Maschen tastet.Arrangement for touching high frequency systems with static frequency converters The main patent specifies a touching method in which the ratio of the machine circuit resistance tv, to the coupling resistance w, is chosen so large in absolute terms that the system can only operate with normal excitation and speed of the machine can easily come into action by closing the switch between the machine and the system and the keying is done by changing this relationship. The investigations made have now shown that the tactile sensitivity of this method can be increased significantly if, according to the present invention, the resistance iv is formed from parts lying in two or more meshes and m one of these meshes is felt.
In der Zeichnung ist in Fig. r eine der im Hauptpatent beschriebenen Anordnungen, nämlich die nach Fig. z dieses Patents wiedergegeben. Die Bedeutung der einzelnen Teile der Anlage ergibt sich ohne weiteres aus der Zeichnung. wp ist hier der Kopplungswiderstand, der parallel zu dem Zweig des Frequenzwandlers f liegt, und wl ist der ganze links von den Klemmen a, a liegende Widerstand.In the drawing, one of those described in the main patent is shown in FIG Arrangements, namely those shown in Fig. Z of this patent. The meaning the individual parts of the system can be seen from the drawing. wp is here the coupling resistance, which is parallel to the branch of the frequency converter f, and wl is the entire resistance to the left of terminals a, a.
Fig. a zeigt eine verbesserte Schaltung nach vorliegender :Erfindung, bei der die Masche des Widerstandes w, der vorigen Figur durch zwei Maschen I und II ersetzt ist. Als Widerstand w't gilt hier wiederum der ganze links von den Klemmen a, a liegende resultierende Widerstand. Das Tastorgan t liegt hier beispielsweise in der ersten Masche.Fig. A shows an improved circuit according to the present invention, in which the mesh of the resistor w of the previous figure is replaced by two meshes I and II. The entire resulting resistance to the left of terminals a, a applies here as resistance w't. The tactile organ t is here, for example, in the first mesh.
