Description
Verfahren zur Spannungsreglung von Fahrzeugmotoren mit Hilfe eines Potentialreglers. Zur Spannungsreglung von Wechselstromfahrzeugmotoren ist ein Verfahren bekannt geworden, bei dem sich ein Potentialregler -an den Anzapfungen eines Stufentransformators abrollt. Nach diesem bekannten Verfahren sind aber für n Spannungsstufen nAnzapfungen am Transformator und daher auch nSchalter erforderlich, während- die Leistung des Reglers rln beträgt.Method for voltage regulation of vehicle engines with the help of a Potential regulator. One method for voltage regulation of AC vehicle motors is became known, in which a potential regulator -an the taps of a step transformer unrolls. According to this known method, however, there are n taps for n voltage levels on the transformer and therefore also nswitch required, while the power of the Controller rln.
Für die Reglung von Fahrzeugmotoren ist es aber mit Rücksicht auf den beschränkten Raum und auf die hohe erforderliche Stufenzahl erwünscht, mit einer sehr geringen Zahl von Schaltern und mit einem Regler von sehr kleiner Leistung auszukommen. Das vorliegende neue Verfahren trägt diesen Anforderungen des Bahnbetriebs Rechnung, weil es gestattet, mit nur wenigen Schaltern, z. B. mit n + m -+- p -f- q Schaltern, angenähert n m p q Stufen zu erreichen und die Leistung des Reglers auf i/nmpq zu vermindern.For the regulation of vehicle engines is but it with Consideration of the limited space and the high number of steps required is desirable, with a very small number of switches and with a regulator of very small size Performance. The present new method meets these requirements bill of rail operations because it allows you to use just a few switches, e.g. B. with n + m - + - p -f- q switches, approximating n m p q levels to achieve and the power of the controller to i / nmpq.
Zur Durchführung des neuen Verfahrens soll die Niederspannungswicklung des Stufentransformators in Gruppen verschiedener Größenordnung unterteilt und die Spannung jeder Gruppe angenähert gleich der Spannung zwischen zwei Anzapfungen einer nächst höheren Gruppe sein.To carry out the new process, the low-voltage winding of the step transformer divided into groups of different sizes and the Voltage of each group approximately equal to the voltage between two taps of one be the next higher group.
Die Abbildung zeigt ein Ausführungsbeispiel.The figure shows an exemplary embodiment.
Die Unterspannungswicklung des Transformators ist in diesem Beispiel in vier Gruppen unterteilt. Ersichtlich ist die Spannung einer ganzen Gruppe niederer Ordnung, jeweils angenähert gleich der Spannung zwischen zwei Anzapfungen einer Gruppe nächst höherer Ordnung. Zu Beginn des Reglungsvorganges sind die Schalter a und o geschlossen. In an sich bekannter Art schreitet die Reglung mit Hilfe eines Reglers in neun Stufen fort. Auf der neunten Stufe sind die Schalter a und 9 geschlossen. Hier beginnt die Übergangsstellung, in der die Schalter a, 9, b, i2 geschlossen sind. Die Gruppe niederster Ordnung ist nunmehr der ersten Stufe der Gruppe nächst höherer Ordnung parallel geschaltet, um jedoch bald danach in der Übergangsstellung b, i i, o mit ihr in Reihe gelegt zu werden. Die Schaltung schreitet nunmehr wieder in neun Stufen fort. Auf der 18. Stufe sind die Schalter b, i i, 9 geschlossen. Es folgen nunmehr wieder die Übergangsstellungen b, 11, 9, 14 und hierauf die Schaltstellungen b, 13, o bis b, 13, 9 usf., bis die 36. Stellung erreicht ist, in der die Schalter b, 15, 9 geschlossen sind. Es folgt der Übergang zur Gruppe noch höherer Ordnung vermittels der Schaltstellung b, 15, 9, c, i9 und c, 18, i o, o us.w.The transformer's low-voltage winding is divided into four groups in this example. The voltage of a whole group of lower order can be seen, in each case approximately equal to the voltage between two taps of a group of the next higher order. At the beginning of the control process, switches a and o are closed. In a manner known per se, the regulation proceeds in nine stages with the aid of a regulator. At the ninth stage, switches a and 9 are closed. This is where the transition position begins, in which switches a, 9, b, i2 are closed. The lowest order group is now connected in parallel to the first stage of the next higher order group, but soon afterwards it is placed in series with it in the transition position b, ii, o. The circuit now proceeds again in nine stages. At the 18th stage, switches b, ii, 9 are closed. The transition positions b, 11, 9, 14 now follow again and then the switching positions b, 13, o to b, 13, 9, etc., until the 36th position is reached, in which the switches b, 15, 9 are closed . This is followed by the transition to the group of an even higher order by means of the switch position b, 15, 9, c, i9 and c, 18, io, o etc.
Nach dem neuen Verfahren werden also durch die Unterteilung der Transformatoren in Gruppen verschiedener Ordnung die in einer Gruppe möglichen Stufenzahlen geradezu potenziert. Im gegehenen Ausführungsbeispiel werden z. B. mit im ganzen 28 Schaltern 9 X 3 X 2 X 2 - io8 bis i o X 4 X 3 X 2 - 240 Schaltstufen erreicht. Es ist nämlich nicht nötig, daß die Spannung zwischen zwei Anzapfungen einer Gruppe genau gleich ist der Gruppenspannung nächst niederer Ordnung. Sie kann auch um eine Stufe der Gruppe niederer Ordnung nach oben oder unten abweichen. Es ist auch nicht notwendig, daß alle Gruppen einem einzigen Transformator angehören. Es können auch zwei oder mehrere Transformatoren (die z. B. auf einem Fahrzeug stehen) in ihren Unterspannungswicklungen, -,vie oben angegeben, in Gruppen unterteilt sein, derart, daß z. B. eine Gruppe höherer Ordnung dem einen Transformator, die Gruppen niederer Ordnung aber einem anderen Transformator angehören.According to the new process, the transformers are divided in groups of different order the number of stages possible in a group exponentiated. In the previous embodiment, for. B. with a total of 28 switches 9 X 3 X 2 X 2 - io8 to i o X 4 X 3 X 2 - 240 switching steps achieved. Because it is it is not necessary that the voltage between two taps of a group is exactly the same is the next lower order of group voltage. You can also go to a level of Lower order group deviate upwards or downwards. It is also not necessary that all groups belong to a single transformer. There can also be two or several transformers (e.g. standing on a vehicle) in their low-voltage windings, -, as indicated above, be subdivided into groups such that e.g. B. a group higher order one transformer, the lower order groups one transformer belong to another transformer.
