Description

Für die Phasenkompenslerung von Asynchronmaschinen schaltet man in deren Sekundärstromkreis eine Kommutatorhintermaschine ein, die mit Selbsterregung arbeitet. 5. Die Anordnung ist dabei derart, daß im Ständer der Kommutatorhintermaschine eine Kompensationswicklung vorgesehen ist und die Nebenschlußerregerwicklung an die Klemmen der Hintermaschine, also an die nach außen führenden Enden der Kompensationswicklung, angeschlossen ist. Es hat sich nun gezeigt, daß bei dieser Schaltung die Kommutatorhintermaschine zu einer kurzschlußartigen Selbsterregung neigt und zu einer unerwünschten Selbsterregung mit Gleichstrom. Diese kurzschlußartige Selbsterregung ist vor allem auf die Wirkung der Kompensationswicklung zurückzuführen, die das Ankerfeld vollständig aufhebt, so daß die Kommutatorwicklung mit der Nebenschlußerregerwicklung ähnlich wie eine an den Klemmen kurzgeschlossene und sich selbst erregende Drehstromrdhenschlußmaschine zusammenarbeitet.For phase compensation of asynchronous machines one switches a commutator rear machine in their secondary circuit one that works with self-excitement. 5. The arrangement is such that in the stand A compensation winding is provided for the commutator rear machine and the shunt excitation winding is connected to the terminals the rear machine, i.e. to the ends of the compensation winding leading to the outside, connected. It has now been shown that in this circuit, the commutator rear machine tends to a short-circuit-like self-excitation and an undesirable self-excitation with direct current. This short-circuit-like Self-excitement is mainly due to the effect of the compensation winding, which cancels the armature field completely, so that the commutator winding with the shunt excitation winding similar to a self-energizing three-phase conduction machine short-circuited at the terminals cooperates.

Gemäß der vorliegenden Erfindung wird diese kurzschlußartige Selbsterregung bzw. auch eine Erregung mit Gleichstrom dadurch unterdrückt, daß die Nebenschlußerregerwicklung nicht an die Klemmen der Kommutatorhintermaschine, sondern parallel zu der Kompensationswicklung und dem äußeren Stromkreise an die Bürsten der Kommutatormaschine angeschlossen ist, so daß der von der Kommutatorwicklung gelieferte Erregerstrom die Kompensationswicklung nicht durchfließt. Dementsprechend wird das Ankerxückwirkungsfeld durch die Kompensationswicklung nicht mehr vollständig aufgehoben und eine kurzschlußartige Selbsterregung wird dadurch unterdrückt. Wollte ein solcher Kurzschlußerregerstrom sich ausbilden, so würde ein starkes Ankerrückwirkungsfeld auftreten, das auf den Kurzschlußstrom wie eine Drosselspule einwirkt. Anderseits besitzt die neue Schaltung aber den Vorteil der Kompensationswicklung, nämlich der Unterdrückung des Einflusses des äußeren Belastungsstromes auf die Feld- und Spannungsverhältnisse in der Maschine. According to the present invention, this short-circuit-like self-excitation or excitation with direct current is also suppressed in that the shunt excitation winding not to the terminals of the commutator rear machine, but parallel to the compensation winding and the external circuit is connected to the brushes of the commutator machine, so that the excitation current supplied by the commutator winding does not affect the compensation winding flows through. The armature feedback field is correspondingly created by the compensation winding no longer completely canceled and a short-circuit-like self-excitation is thereby suppressed. Wanted a Such a short-circuit excitation current would develop, a strong armature reaction field would be created occur, which acts on the short-circuit current like a choke coil. On the other hand However, the new circuit has the advantage of the compensation winding, namely the suppression the influence of the external load current on the field and voltage conditions in the machine.

Die Zeichnung veranschaulicht die Schaltung gemäß der Erfindung. 1 ist eine Asynchronmaschine, in deren Sekundärstromkreis die mechanisch gekuppelte Kommutatorhintermaschine 2 eingeschaltet ist. Diese besitzt im Ständer eine Kompensationswicklung 3 und eine Nebenschlußerregerwicklung 4, die an die Verbindungen zwischen der Kompensationswicklung und den Bürsten am Kommutator angeschlossen ist.The drawing illustrates the circuit according to the invention. 1 is an asynchronous machine, in the secondary circuit of which the mechanically coupled commutator rear machine 2 is switched on.
