Description

Regelvorflütung zum Ingangsetzen eines Spinnstubles mit Drebstromflügelmotoren. Beim Ingangsetzen eines Spinnstuhles mit Drehstromflügelmotoren, deren Speisung von einem Asynchrongenerator, Asynchronumformer, Frequenzwandler o.dgl. geschieht, ist bisweilen ein Zurückdrehen der Flügel beobachtet worden. Die Folge hiervon waren Schagenbildungen und Fadenbrüche, also ierhöhte Schwierigkeiten beim Ingangsetzen, wo ohnehin jede Spinnmaschine empfindlich ist und einer vermehrten, aufmerksamen Bedienung `bedarf, um Erzeugungsausfälle möglichst zu vermeiden. Das Zurückdrehen der Flügel kann nur dadurch erklärt werden, daß rücklÄufige Drehfelder vorhanden sind, die offenbar in£-olge der SchallvorgÄbige auftreten.Control pre-flooding for starting a spinning room with three-flow vane motors. When starting a spinning chair with three-phase vane motors, their supply from an asynchronous generator, asynchronous converter, frequency converter or the like. happens a turning back of the wings has sometimes been observed. The consequence of this were Loose formation and thread breaks, i.e. increased difficulties when starting up, where every spinning machine is sensitive anyway and one that is increased and attentive service `in order to avoid generation failures as far as possible. The turning back of the wings can only be explained by the fact that backward turning fields are present, which apparently appear in the sequence of the sound prediction.

Erfindungsgemäß wird ein Zurückdrehen der Flügel daduTch verrnieden, daß die die Flügelmoteren speisenden Stromschienen während der Zeit, wo eine Rückdrehung auftreten könnte, - kurzgeschlossen werden. Auf diese Weise werden die Flügelmotoren erst an die, Arbeitsspannung gelegt, wen eine einem rückläufigen Drehfeld entsprechende Spajinung nicht mehr auftretm kann.According to the invention a turning back of the wing is daduTch verrnieden that the Flügelmoteren feeding current rails, during the time when a reverse rotation could occur - are short-circuited. In this way, the vane motors are only connected to the working voltage when a spin corresponding to a declining rotating field can no longer occur.

Eine derartige Anordnung ließe sich beispielswelmile entsprechend dem anliegenden Schaltbild ausführen.Such an arrangement could, for example, be used accordingly execute the attached circuit diagram.

a ist eine Schaltwalze mit darauf schleifenden Kontaktfingern b bis ni. Die Kontaktfinger b, c# d Aind mit den Schleifhngen it, o, p des Generators q einerseits und den Sammelschien,enr,s,i für die Speisung der Flügelmotoren u verbunden. Die Schaltwalze hat eine Axizahl Stellungen für das Anlassen und die verschiedenen Betriebsstellungen des, Spinnstuhles, die der übersichtlichkeit halber fortgelassen sind, da sie je nach den besonderen Verhältnissen des Betriebes und des verwendeten Generators verschieden ausgeführt sein können. Zwischen den Anlaßstellungen I und II ist auf der S-Chaltwalze a ein, Kontaktstück v angebracht, welches die Kontaktfinger b, c, d gleichzeitig berühren. Es ist angenommen, daß an dieser Stelle Spannungen auftreten können, die einem rücklÄufigen Drehfeld entsprechen, und es ist ohne weiteres ersichtlich, daß durch- das Kurzschließen der Finger b, c, d die Sammelschienen #", s, i und damit auch die Flügelmotoreu zeitweise stromlos gemacht werden. Um den das Kontaktstück V und die Finger durchflie-Benden Kurzschlußstrom zu vermindern und die beim Abgleiten der Bürsten b, c, d entstehenden Funken zu vernündern, kann es sich unter Umständen empfehlen, das Kontaktstück in drei Einzelkontakte aufzulösen, die durch Widerstände miteinander leitend verbunden sind. Diese Widerstände können in der Schaltwallze selber untergebracht oder auch an besondere die Einzelkontakte bestreichende Finger angeschlossen werden. Diese, Widerstände müssen jedoch so gering bemessen werden, daß an die Sammelschienen r, s, 1 keine Spannungen kommen, die ein Drehen der Flügelmotoren bewirk= könnten.a is a shift drum with contact fingers b to ni sliding on it. The contact fingers b, c # d Aind are connected to the loop hangings it, o, p of the generator q on the one hand and the bus bars, enr, s, i for supplying the vane motors u. The shift drum has an axial number of positions for starting and the various operating positions of the spinning chair, which are omitted for the sake of clarity, as they can be designed differently depending on the particular conditions of the operation and the generator used. Between the starting positions I and II, a contact piece v is attached to the S-chalt roller a, which the contact fingers b, c, d touch at the same time. It is assumed that voltages can occur at this point which correspond to a retrograde rotating field, and it is readily apparent that the short-circuiting of fingers b, c, d causes busbars # ", s, i and thus also the vane motorsu In order to reduce the short-circuit current flowing through the contact piece V and the fingers and to negate the sparks that occur when the brushes b, c, d slide, it may be advisable to break up the contact piece into three individual contacts, which are connected by resistors to one another conductively. These resistors can be accommodated or in the Schaltwallze itself also to particular the individual contacts bestreichende fingers are connected. However, these, resistors must be dimensioned so small that r to the busbars, s, 1 no stresses occur, which a turning of the vane motors could cause.
