Description

Verfahren zur Regelung von mit Wechselstrommotoren verhältnismäßig niederer Spannung angetriebenen Schienenfahrzeugen Aus dem Hauptpatent ist ein Verfahren zur Regelung von mit Wechselstrommotoren verhältnismäßig niederer Spannung betriebenen Schienenfahrzeugen bekannt, die über einen Leistungstransformator an eine Hochspannungsfahrleitung von mindestens ioooo Volt Betriebsspannung angeschlossen sind. Das Verfahren besteht darin, daß die Fahrgeschwindigkeit mit Hilfe von Anzapfungen geregelt wird, die sich an der Oberspannungswicklung .des Leistungstransformators befinden. Gemäß dem Ausführungsbeispiel soll bei der Regelung an diesen Anzapfungen entlang der Anschluß der Fahrleitungsspannung geschaltet werden.Method of controlling with AC motors proportionately Low voltage driven rail vehicles From the main patent is a process for regulating relatively low voltage operated with AC motors Known rail vehicles that are connected to a high-voltage contact line via a power transformer of at least 100 volts of operating voltage are connected. The procedure persists in that the speed is controlled with the help of taps, the are located on the high-voltage winding of the power transformer. According to the Embodiment is intended to control these taps along the connection the contact line voltage can be switched.

Wenn nun die Anzapfungen des Transformators nicht auf die ganze Oberspannungswicklung verteilt sind, sondern sich nur über einen Abschnitt derselben erstrecken, so läßt sich nach der vorliegenden- Erfindung eine Ersparnis dadurch erzielen, daß man nicht den Anschluß der Fahrleitungsspannung an den Anzapfungen der Oberspannungswicklung entlang schaltet, sondern den Anschluß der Erdleitung. Der bewegliche Teil des Regelungsschalters braucht dann überhaupt nicht isoliert zu sein, und auch von den Anzapfungen -der Oberspannungswicklung erhält keine mehr als einen Bruchteil der Hochspannung, so daß Transformator und Regelschalter leichter und billiger werden.If now the taps of the transformer are not on the whole high-voltage winding are distributed, but only extend over a section of the same, so can According to the present invention, a saving can be achieved in that one does not the connection of the contact line voltage to the taps of the high-voltage winding switched along, but the connection of the earth line. The moving part of the control switch then does not need to be isolated at all, and also from the taps -the High voltage winding does not receive more than a fraction of the high voltage, so that transformers and control switches are lighter and cheaper.

In der Zeichnung ist die neue Schaltung schematisch dargestellt. Wie im Hauptpatent bedeutet a die Hochspannungsfahrleitung, b den Stromabnehmer, c den Hauptschalter, d die mit erdseitigen Anzapfungen i bis 7 versehene Oberspannungswicklung, f die Unterspannungswicklung des Leistungstransformators und g die Triebmotoren. Die Regelvorrichtung 1a ist hier mit der Erde e verbunden, während das erdseitige Ende der Oberspannungswicklung d ohne feste Verbindung gelassen ist. Man erkennt, daß die Regelvorrichtung hier immer Erdpotential hat und daß das Potential der höchsten Anzapfung 7 niemals dasjenige der Fahrleitung a erreicht.The new circuit is shown schematically in the drawing. As In the main patent, a means the high-voltage contact line, b the pantograph, c denotes Main switch, d the high-voltage winding provided with earth-side taps i to 7, f the low voltage winding of the power transformer and g the traction motors. The control device 1a is connected to the earth e, while the earth-side The end of the high-voltage winding d is left without a fixed connection. One recognises, that the control device here always has ground potential and that the potential of the highest Tap 7 never reaches that of contact line a.
