Description

Einrichtung zur Erregung; einer Synchronmaschine Gegenstand des Iiauptpatenfis (Anmeldung S 109 66¢ VIIIb/21d2) ist eine Einrichtung zur Erregung einer Synchronmaschine, deren r:1i ttels kontaktloser Schaltelemente kurzschließbarer Erreger- wicktun- an einen rotierenden Gleichrichter angeschlossen ist. In der Erregereinrichtung sind P:Fitte-IL vorgesehen, die den Ström in der Erregerwicklung sowohl in Abhängigkeit von der Größe, als auch in Abhängigkeit von der Frequenz,der Anlaufwechsel- Spannung, beeinflussen. Zur Begrenzung der Anlaufwechselspannung kann vorteilhaft parallel zur Erregerwicklung eine Antiparallelschaltung von gesteuerten Querventilen, insbesondere Thyrisroren vorgeaerer@ sein, die -in Abhängigkeit von der Höhe der Anlau#@arechsel,pannangesteuert werden. In Reihe mit der Erregerwick?ung kanr Zweckmäßig ein gesteuertes Längsventil angeorunet 'ein, uas in Ab- hängigkeit von der l rectueriz der Anlaufwechselspannung gezündet wird, sobald der Schlup" einen e? nstellbaren »,fiert erreicht, den sogenannten Intrittfallschlupf. . Die Erfindung geht nun aus von der Erkenntn.Cs; daß die Einrichtung nach der fiaup tanmeidung nicht auf die 'de rwendun: rotierender Gleichr=ichter beschränkt ist. Die Eriiridun_r besteh. somit in der Verwendung der Einrichtung nach der Hauptanmeldung zur Erregung einer Synchronmv.schine, deren Erregerwicklung an eine ruhende Gleiehspannungsquelle angeschlossen ist. Die Erregerwicklung kann vorteilhaft mittelbar, beispielsweise über Schleifringe, an den Gleichstromgenerator eines Erregerumformers oder auch an den Ausgang eines ruhenden Gleichrichters angeschlossen sein. Die gesteuerten Querventile und das_Längsventil mit den zugehörigen Steuereinrichtungen nach der Hauptanmeldung können dann mindestens einen wesentlichen `Peil der üblichen Anlaufeinrichtung, insbesondere eine Anlaufautomatik, ersetzen.Device for arousal; a synchronous machine Subject of the main sponsorship (registration p. 109 66 ¢ VIIIb / 21d2) is a device for exciting a synchronous machine whose r: 1 by means of contactless switching elements short-circuited exciter wicktun is connected to a rotating rectifier. In the excitation device P: Fitte-IL are provided, which the flow in the excitation winding both depending on the size, as well as depending on the frequency, the starting alternation Tension, affect. To limit the starting AC voltage, an antiparallel connection of controlled cross valves, in particular thyrisrors, can advantageously be operated in parallel with the excitation winding, which are pann-controlled depending on the height of the starting arm. Uas is ignited as a function of the rectueriz l the start-up AC voltage in series with the field Wick? Ung kan Appropriately angeorunet a controlled longitudinal valve 'one, as soon as the creep reached "an e? Nstellbaren" fiert, the so-called. Intrittfallschlupf. The invention is now based on the realization that the device after the avoidance of the fiaup is not restricted to the 'de rwendun: rotating rectifier. whose excitation winding is connected to a stationary DC voltage source. The excitation winding can advantageously be connected indirectly, for example via slip rings, to the direct current generator of an exciter converter or to the output of a stationary rectifier an essential hen `replace the bearing of the usual start-up device, in particular an automatic start-up.
