Description

Selbsterregender Wechsel- oder Drehstrom-Asynchrongenerator Die Erfindung bezieht sich auf selbsterregende Wechsel- oder Drehstrom-Asynchrongeneratoren, bei denen eine dem Drehfelde in der Maschine proportionale Spannung einen Erregerstrom über einen Kommutator in eine auf dem sekundären Teile befindliche, von der Arbeitswicklung getrennte Erregerwicklung schickt. Bei derartigen Maschinen kann man mit Hilfe eines Stromtransformators, dessen eine Wicklung vor der am Netz liegenden Dynamowicklung und dessen zweite Wicklung vor dem Kommutator liegt, eine selbsttätige Kompoundierung der Maschine erreichen. Diese Kompoundierung wird aber dadurch erschwert, daß der von der Ständerhilfswicklung kommende Leerlauf-Erregerstrom und der aus dem Stromtransformator kommende Lasterregerstrom gemeinsam in die Kollektorwicklung eintreten sollen. Ein Teil des Lasterregerstromes wird sich über die Ständerhilfswicklung schließen.Self-exciting alternating or three-phase asynchronous generator The invention refers to self-exciting alternating or three-phase asynchronous generators, at where a voltage proportional to the rotating field in the machine generates an excitation current via a commutator into a secondary part of the working winding separate excitation winding sends. With such machines you can use a Current transformer, one winding of which is before the dynamo winding connected to the network and whose second winding is in front of the commutator, an automatic compounding of the machine. This compounding is made more difficult by the fact that the no-load excitation current coming from the stator auxiliary winding and that from the current transformer incoming load excitation current should enter the collector winding together. A Part of the load excitation current will close via the stator auxiliary winding.

Dieser Nachteil wird gemäß der Erfindung dadurch beseitigt, daß die Vereinigung der beiden Stromzweige nicht an den Bürstenbolzen, sondern erst am Kommutator erfolgt. Bei der Verwendung nur eines Kommutatorbürstensatzes setzt man die Bürsten der beiden Erregerstromzweige auf dieselben Bürstenspindeln, aber voneinander isoliert.This disadvantage is eliminated according to the invention in that the Unification of the two branches not at the brush bolt, but only at the commutator he follows. If only one set of commutator brushes is used, the brushes are set of the two excitation branches on the same brush spindles, but isolated from each other.

In der Zeichnung ist die Erfindung beispielsweise schematisch dargestellt. Hierin ist w i die am Netz liegende Gehäusehauptwicklung, w :z eine im Läufer befindliche, im Betriebe kurzgeschlossene Wicklung, die hauptsächlich Wirkstrom führt, w 3 eine im Läufer befindliche Kommutatorwicklung, die mit ihrem Strome das magnetische Feld erzeugt, w q. eine im Ständer befindliche Hilfswicklung, die die Wicklung w 3 speist, t i die primäre und t 2 die sekundäre Wicklung des Stromtransformators.The invention is shown schematically, for example, in the drawing. Here wi is the main housing winding connected to the network, w: z a winding located in the rotor, short-circuited during operation, which mainly carries active current, w 3 is a commutator winding located in the rotor, which generates the magnetic field with its current, w q. an auxiliary winding located in the stator, which feeds the winding w 3 , t i the primary and t 2 the secondary winding of the current transformer.
