Zusatz zum Patente 125920 vom 4. November 1900.Addendum to patent 125920 from November 4, 1900.
Patentiert im Deutschen Reiche vom 11. Oktober 1905 ab. Längste Dauer: 3. November 1915.Patented in the German Empire on October 11, 1905. Longest duration: November 3, 1915.
Unter den in der Patentschrift 125920 beschriebenen Anordnungen, durch welche die Amperewindungszahl der Elektromagnete von Starkstromapparaten für Gleichstrom bei plötzliehen Belastungsänderungen selbsttätig geregelt werden kann, ist auch eine Anordnung, welche darin besteht, daß parallel oder in Reihe zu der Magnetwicklung induktive Widerstände geschaltet sind. Diese Anordnung kann nach der Erfindung dadurch besonders wirksam gestaltet werden, daß der induktive Widerstand von der Sekundärwicklung eines Transformators gebildet wird, dessen Primärwicklung im ungeteilten Stromkreise liegt.Among the arrangements described in patent specification 125920 by which the Amperage of turns of the electromagnets of power equipment for direct current in the case of sudden ones Load changes can be regulated automatically, is also an arrangement, which consists in that parallel or in Inductive resistances are connected in series to the magnet winding. This arrangement can be made particularly effective according to the invention that the inductive resistance of the secondary winding of a transformer is formed, the primary winding of which is in undivided circuits lies.
Die Zeichnung zeigt beispielsweise die Anwendung dieser Verbesserung zur Regelung der Hauptstromwicklung s eines Gleichstromerzeugers e. Parallel zur Magnetwicklung s liegt die Sekundärwicklung w eines Transformators; die Primärwicklung ρ liegt in der unverzweigten Leitung. Der Eisenkern a des Transformators besitzt eine Luftspalte b. Dadurch wird eine starke Remanenz des Eisenkernes nach dem Aufhören der magnetisierenden Kraft verhütet; auch wird dadurch Proportionalität zwischen der letzteren und dem durch sie erzeugten Kraftflusse erreicht.The drawing shows, for example, the use of this improvement for regulating the main current winding s of a direct current generator e. The secondary winding w of a transformer is parallel to the magnet winding s; the primary winding ρ lies in the unbranched line. The iron core a of the transformer has an air gap b. This prevents a strong remanence of the iron core after the magnetizing force has ceased; this also achieves proportionality between the latter and the flux of forces generated by it.
Solange die Belastung konstant ist oder sich nur sehr langsam ändert, verteilt sich der Hauptstrom auf die Wicklungen s und w im umgekehrten Verhältnisse der ohmschen Widerstände. Ändert sich der Hauptstrom aber plötzlich, so induziert die Wicklung ρ in der Wicklung n> eine elektromotorische Kraft, und diese erzeugt einen Strom, welcher sich innerhalb ,der beiden für den Maschinenstrom parallelen, für den induzierten Strom in Reihe liegenden Zweige ρ -\- s und w schließt und. sich in dem einen Zweige zu dem in diesem fließenden Teilstrome des Maschinenstromes addiert, dagegen im anderen Zweige sich von dem in letzterem fließenden Teilstrome subtrahiert, also die Stromverteilung zugunsten des ersteren Zweiges beeinflußt. Bei dem angegebenen' Ausführungsbeispiele ist der Wicklungssinn der Wicklungen ρ und w so zu wählen, daß bei plötzlicher Belastungszunahme der in n> fließende Teilstrom durch den in n> induzierten Strom geschwächt, dagegen der in der Magnetwicklung s fließende Teilstrom verstärkt wird, damit der Feldmagnet trotz der verzögernden Wirkung, welche die bei plötzlicher Änderung des Erregerstromes in seinen Kernen erzeugten Wirbelströme ausüben, schnell die der neuen Belastung entsprechende Magnetstärke annimmt. Bei plötzlich sinkender Belastung ist die Wirkungsweise die umgekehrte. Solange die Belastung konstant ist, wirkt die Wicklung w nur als Nebenschlußwiderstand; es kann da-As long as the load is constant or changes only very slowly, the main current is distributed to the windings s and w in the inverse proportion of the ohmic resistances. If the main current changes suddenly, however, the winding ρ induces an electromotive force in the winding n> , and this generates a current which is within the two branches ρ - \ - , which are parallel for the machine current and in series for the induced current. s and w includes and. in one branch is added to the partial flow of the machine current flowing in this, on the other hand it is subtracted in the other branch from the partial flow flowing in the latter, thus influencing the current distribution in favor of the former branch. The specified 'embodiments of the winding sense of the windings is ρ and w to be selected so that the weakened under sudden load increase in n> flowing partial flow through the induced in n> current, however, is amplified in the magnetic coil s flowing partial flow so that the field magnet despite the retarding effect exerted by the eddy currents generated in its nuclei when the excitation current changes suddenly, it quickly assumes the magnetic strength corresponding to the new load. If the load suddenly drops, the effect is the opposite. As long as the load is constant, the winding w only acts as a shunt resistor; it can-
