Description

Schnellregler mit vergrößertem Regelbereich Die Erfindung bezieht sich auf Schnellregler mit vergrößertem Regelbereich, bei denen der von den Schnellreglerkontakten periodisch kurzgeschlossene Widerstand aus einer derartigen Kombination von konstantem und spannungsabhängigem Widerstand besteht, daß bei kleiner Erregerspannung der Widerstand groß und bei großer Erregerspannung der Widerstand klein ist.Rapid regulator with enlarged control range The invention relates on fast regulators with a larger control range, in which that of the fast regulator contacts periodically shorted resistance from such a combination of constant and voltage-dependent resistance is that when the excitation voltage is small Resistance is large and when the excitation voltage is high, the resistance is small.

Es ist nun bereits vorgeschlagen worden, zwecks Unterstützung des Regelvorganges der Erregermaschine einen spannungsabhängigen Widerstand mit Vorheizung zu verwenden, der parallel zu dem Regelwiderstand liegt und dessen Heizspule ,an die zu regelnde Spannung angeschlossen ist. Sofern der Regler nicht arbeitet, wird die. Heizung des spannungsabhängigen Widerstandes mittels eines zusätzlichen, mit dem Hauptregelwiderstand gekoppelten Regel"iderstandes geschwächt.It has now been proposed in order to support the Control process of the exciter a voltage-dependent resistor with preheating to be used, which is parallel to the rheostat and its heating coil the voltage to be regulated is connected. If the controller is not working, will the. Heating of the voltage-dependent resistor by means of an additional, with the main control resistor coupled rule "iderstandes weakened.

Gemäß der Erfindung wird nun auch der den Heizstrom regelnde zusätzliche Regelwiderstand von Kontakten des Schnellreglers periodisch überbrückt. Dadurch wird eine Vergrößerung des Heizstromeffektes sowie eine schnelleere Vergrößerung und Verringerung des Heizstromes erzielt.According to the invention, the additional one that regulates the heating current is now also used Rule resistance of contacts of the fast regulator periodically bridged. Through this becomes an enlargement of the heating current effect as well as a faster enlargement and reduction of the heating current achieved.

Die Schaltung nach der Erfindung ist in der Zeichnung beispielsweise veranschaulicht. S ist ein Drehstromgenerator, dessen Feld-Wicklung von der Haupterregerma.schine E gespeist wird. Die Feld«zcklung dieser Erregermaschine liegt über dem H.auptregelwiderstand W mit den Schnellreglerkontakten T an der annähernd konstanten Spannung der Hilfserregermaschine p. Parallel zu dem Hauptregelwiderstand tv sind zwei mit je einem festen, einstellbaren Widerstand 12t und R, in Reihe liegende spannungsabhängige Widerstände U1 bzw. U@ geschaltet, deren Heizspulen Hl bzw. H., über den mit dem Hauptregelwide-rstand tv b koppelten Heizregel"iidersta.ndm und den Vorschalt-,viderstandR, an der Haupt.erregerspannung liegt. Parallel zu dem Heizregelwiderstand m liegen die Schnellregierkontakte T1, durch die der Widerstandm über Widerstand 12t periodisch überbrückt wird.The circuit according to the invention is shown in the drawing, for example illustrated. S is a three-phase generator whose field winding is from the main exciter E is fed. The field coverage of this exciter is above the main control resistor W with the fast regulator contacts T to the approximately constant voltage of the auxiliary exciter p. Parallel to the main variable resistor tv there are two, each with a fixed, adjustable one Resistor 12t and R, voltage-dependent resistors U1 and U @ connected in series switched, their heating coils Hl or H., via the rstand with the main control tv b coupled heating control "iidersta.ndm" and the ballast, resistorR, to the main excitation voltage lies. The quick control contacts T1 are parallel to the heating control resistor m, by which the resistor m is periodically bridged via resistor 12t.
