Zusatz zum Patente 204207 vom 3. Januar 1908.Addendum to patent 204207 of January 3, 1908.
Patentiert im Deutschen Reiche vom 18. März 1908 ab. Längste Dauer: 2.Januar 1923.Patented in the German Empire on March 18, 1908. Longest duration: January 2, 1923.
Gegenstand der Erfindung ist eine Weiterbildung der in der Patentschrift 204207 beschriebenen Einrichtung. Die neuen Schaltungsweisen beziehen sich besonders auf den Fall, daß an den Transformatoren sowohl primär als auch sekundär nur Hochspannung zur Verfügung steht, so daß die unmittelbare Einschaltung der Relaiswicklungen in die Hochspannungsleitung Schwierigkeiten verursachen würde. Man erreicht den gewünschten Zweck nun dadurch, daß man das Relais mit einer oder zwei Wicklungen f1, g1 versieht, welche in ihrer Wirkung auf das Relais den Wicklungen f und g des Hauptpatents entsprechen und mit den Sekundärwicklungen p und q .zweier Stromwandler in geeigneter Weise verbunden werden, deren Primärwicklungen in den Stromkreisen des dauernd eingeschalteten Transformators I und des parallel zu schaltenden Transformators II, und zwar auf den Primär- oder Sekundärseiten liegen.The subject of the invention is a further development of the device described in patent specification 204207. The new circuit methods relate particularly to the case that only high voltage is available on the transformers, both primarily and secondarily, so that the immediate connection of the relay windings in the high-voltage line would cause difficulties. The desired purpose is achieved by providing the relay with one or two windings f 1 , g 1 , which in their effect on the relay correspond to the windings f and g of the main patent and with the secondary windings p and q. Two current transformers in are connected in a suitable manner whose primary windings are in the circuits of the permanently switched on transformer I and the transformer II to be connected in parallel, on the primary or secondary sides.
Ist es z. B. erforderlich, daß nach erfolgter Zuschaltung des zweiten Transformators der Magnetismus des Relais verstärkt werde, so wird die Schaltung so getroffen, daß sich die Ströme in den Wicklungen f1 und g1 addieren (Fig. 1) (vgl. Ausführung nach Fig. 3 des Hauptpatents). Ist jedoch eine Schwächung erforderlich, so werden die Wicklungsenden zwischen einer Spule und dem zugehörigen Stromtransformator vertauscht, wodurch sich dann die Ströme subtrahieren (Fig. 2) (vgl. hierzu Ausführung nach Fig. 4 des Hauptpatents. Is it z. If, for example, it is necessary that the magnetism of the relay is amplified after the second transformer has been switched on, the circuit is made so that the currents in the windings f 1 and g 1 add up (Fig. 1) (see the embodiment according to Fig. 3 of the main patent). If, however, a weakening is required, the winding ends are exchanged between a coil and the associated current transformer, so that the currents are then subtracted (FIG. 2) (cf. embodiment according to FIG. 4 of the main patent.
Die Regelung der Stromstärke selbst kann bei beiden Ausführungen in bequemer Weise durch eine zur Wicklung q parallelgeschaltete, gegebenenfalls regelbare Drosselspule oder einen Widerstand w erfolgen (Fig. 2). .The regulation of the current intensity itself can take place in both versions in a convenient manner by means of an optionally adjustable choke coil or a resistor w connected in parallel to the winding q (FIG. 2). .
Es ist natürlich auch hier möglich, den Grad der Schwächung oder Verstärkung des Magnetismus nach erfolgter Zuschaltung des zweiten Transformators nach Art der Fig. 6 in dem Hauptpatent zu bewirken, indem die Streuung zwischen den beiden Spulen/1 und g1 verändert wird.It is of course also possible here to effect the degree of weakening or strengthening of the magnetism after the second transformer has been connected in the manner of FIG. 6 in the main patent by changing the scatter between the two coils / 1 and g 1.
