werden, der zu dem Erregervorschaltwiderstand führt, oder es kann auch rein elektromagnetisch durch Einschalten eines Elektromagneten in die Wechselstromteitung ein Kontakt betätigt werden, der beim Schiessen des Tasters einen Widerstand abschaltet, beim Öffnen ihn zuschaltet,
EMI2.1
ein Amperemeter zur Messung des Erregerstromes, IV die Wechselstromwicklung mit den
Enden U und V, T der Taster und Tr der an den Enden U V angeschlossene Hoch- spannungstransform3. tor, In die Erregerwicklung-E der Maschine ist ein Regulierwiderstand R eingeschaltet, der ausser einem festen Anschluss zwei Schleifkontakte a und b besitzt.
Der
Taster T ist nach der Figur mit einem zweiten Taster zwangläufig verbunden, der einer- seits zum festen Anschluss des Regulierwiderstandes R, andrerseits zum Schleifkontakt a führt ; der Schleifkontakt b führt zur Erregerwicklung E.
Mit Hilfe der Schleifkontakte a und b lässt sich nun der Erregerstrom so einstellen, das bei Strich und Punkt immer der gleiche Wert erreicht wird, wodurch in beiden Fällen ein guter Ton zu erzielen ist.

which leads to the excitation series resistor, or a contact can also be actuated purely electromagnetically by switching on an electromagnet in the AC line, which switches off a resistor when the button is closed and switches it on when it is opened,
EMI2.1
an ammeter for measuring the excitation current, IV the alternating current winding with the
Ends U and V, T of the button and Tr of the high-voltage transformer connected to the ends of U V3. tor, A regulating resistor R is connected to the exciter winding E of the machine, which has two sliding contacts a and b in addition to a fixed connection.
The
According to the figure, button T is inevitably connected to a second button which, on the one hand, leads to the fixed connection of the regulating resistor R and, on the other hand, to the sliding contact a; the sliding contact b leads to the excitation winding E.
With the help of sliding contacts a and b, the excitation current can now be set in such a way that the same value is always achieved for the line and dot, so that a good tone can be achieved in both cases.
