Description
Die Erfindung bezieht sich auf Kaskadenumformer zum Umformen von Ein- oder Mehrphasenstrom in Gleichstrom, welche aus einer Induktionsmaschine in Hintereinander-Schaltung mit einem Drehfeldumformer bestehen und eine Regelung der Gleichspannung in weiten Grenzen ermöglichen.The invention relates to cascade converters for forming one or Multiphase current in direct current, which comes from an induction machine in series connection exist with a rotary field converter and enable regulation of the DC voltage within wide limits.
Erfindungsgemäß wird das stillstehende Feld im Gleichstromteil des Umformers zwecks Regelung der Gleichspannung gegenüber dem feststehenden Bürstensatz verdreht, und zwar durch das Zusammenwirken von zwei einerseits auf dem Läufer, andererseits auf dem Umformerständer angeordneten Hilfswicklungen, von welchen letztere im Raum verdrehbar angeordnet ist. Diese Hilfswicklungen dienen gleichzeitig dazu, ähnlich wie bei einer doppelt gespeisten Maschine den synchronen Gang des Umformers aufrechtzuerhalten.According to the invention, the stationary field is in the direct current part of the converter rotated in relation to the fixed brush set for the purpose of regulating the DC voltage, namely through the interaction of two on the one hand on the runner, on the other hand Auxiliary windings arranged on the converter stand, of which the latter in the Space is arranged rotatable. These auxiliary windings also serve, similar to a double-fed machine to maintain the synchronous operation of the converter.
Der Umformer nach der Erfindung gewährt wie jeder Kaskadenumformer den Vorteil absoluter Unabhängigkeit der Sekundär- von der Primärspannung. Wie bei den bekannten Ausführungen können auch bei der Erfindung die Kommutierungsverhältnisse durch entsprechende Wahl des Polzahlverhältnisses der Induktionsmaschine und des Drehfeldumformers verbessert werden.The converter according to the invention grants like any cascade converter The advantage of absolute independence of the secondary from the primary voltage. Like the known designs can also be used in the invention, the commutation ratios by selecting the number of poles ratio of the induction machine and the Rotary field converter can be improved.
Dabei kann die Arbeits- und umlaufende Hilfswicklung des Drehfeldumformers auf dem Läufer, die ruhende Hilfswicklung aber auf dem Ständer des Drehfeldumformers angeordnet werden.The working and circumferential auxiliary winding of the rotary field converter can be used the rotor, but the stationary auxiliary winding is arranged on the stator of the rotary field converter will.
Zur Behebung der Schwierigkeiten, welche durch die Feldverdrehung gegenüber dem ruhenden Bürstensatz in der Stromwendung auftreten, stehen die namentlich in der Anfangszeit des Kommutatormaschinenbaues zur Umgehung der Anwendung von zusätzlichen Kommutierungsfeldern erfundenen Methoden zur Verfügung.To remedy the difficulties caused by the field rotation compared to the dormant brush set occur in the commutation, they stand specifically in the initial period of the commutator machine construction to circumvent the use of additional commutation fields invented methods to disposal.
