Description

Aus Einphasentransformatoren bestehender mehrphasiger Streutransformator Eine verlustlose und stufenlose Regelung von Mehrphasenstrom läßt sich durch Streutransformatoren, die verstellbare Streujoche besitzen, erzielen. Beispielsweise hat man drei Einphasentransformatoren in sternförmiger Anordnung zusammengestellt und dazwischen mittels einer Spindel in der Achsrichtung verschiebhare oder teils feste, teils verschiebbare Streujoche angebracht. Die bauliche Durchbildung solcher und ähnlicher stetig verstellbarer Streujoche bietet jedoch Schwierigkeiten, namentlich weil .die Antriebsvorrichtung für das Jochstück eine störend große Bauhöhe erfordert. Auch wird :die Bewegungsmöglichkeit des Joches durch die Spulen beeinträchtigt.Multi-phase distribution transformer made up of single-phase transformers Lossless and stepless regulation of multiphase current can be achieved by means of scatter transformers, have the adjustable Streujoche achieve. For example, you have three single-phase transformers put together in a star-shaped arrangement and in between by means of a spindle in the axial direction movable or partly fixed, partly movable Streujoche appropriate. The structural formation of such and similar is continuously adjustable Streujoche, however, presents difficulties, namely because .the drive device requires a disruptive height for the yoke piece. Also becomes: the possibility of movement of the yoke affected by the coils.

Gemäß der Erfindung werden diese Nachteile dadurch vermieden, daß -die Einphasentransformatoren in parallelen Ebenen nebeneinanderliegen, und :daß das Streujoch in Bezug auf die Einphasentransformatoren drehbar gelagert ist.According to the invention, these disadvantages are avoided in that -the single-phase transformers are located next to each other in parallel planes, and: that the Streujoch is rotatably mounted with respect to the single-phase transformers.

In der Fig. i i%t schematisch ein Transformator gemäß der Erfindung dargestellt. Er besteht aus drei Einphasentransformatoren i, 2 und 3, von denen jeder einen selbständigen Magnetkreis (Eisenkreis q., 5 bzw. 6) besitzt. Auf diesen Magnetkreisen sitzen die Primärspulen 7, $ und 9 sowie die Sekundärspulen i o, i i und 12. Die Primärspulen und .die Sekundärspulen können entweder in Stern geschaltet sein, wie die Figur zeigt, oder aber in Dreieck. Die Magnetkreise ,l, 5 und 6 werden durch zwei Streujoche 13 und 1q. magnetisch miteinander gekoppelt. Eines der Streujoche, z. B. 13, wird verstellbar angeordnet. Je näher dieses Streuloch an die Magnetkreise herangebracht wird, um so größer wird die Streuung und damit bei gegebener Belastung um so kleiner die Sekundärspannung.In Fig. I i% t schematically a transformer according to the invention shown. It consists of three single-phase transformers i, 2 and 3, one of which each has an independent magnetic circuit (iron circle q., 5 or 6). On this Magnetic circuits sit the primary coils 7, $ and 9 and the secondary coils i o, i i and 12. The primary coils and the secondary coils can either be connected in star be, as the figure shows, or in a triangle. The magnetic circuits, 1, 5 and 6 will be by two Streujoche 13 and 1q. magnetically coupled to each other. One of the Streujoche, z. B. 13 is arranged to be adjustable. The closer this stray hole to the magnetic circuits is brought up, the greater the scatter and thus with a given load the smaller the secondary voltage.

In der Fig. 2 sind schematisch die Magnetsysteme eines Transformators nach der Erfindung "dargestellt. Es gelten hier dieselben Bezugszeichen wie in der Schaltung nach der Fig. i. Die drei Magnetkreise q., 5 und 6 sind nebeneinander angeordnet. An dereinen Stirnseite befindet sich ein festes Streujoch 14. und an der anderen Seite ein bewegliches Streujoch 13, das beispielsweise an zwei Hebeln 15 und 16 befestigt ist, die um. die Punkte 17 und 18 schwenkbar sind. Mit Hilfe einer in der Figur nicht gezeichneten Verstellvorrichtung (beispielsweise Schraubspindel) kann man das Streujoch 13 den Magnetkreisen q., 5 und 6 beliebig nähern und so die Streuung und damit die elektrischen Daten des Streutransformators ,ändern.In Fig. 2, the magnet systems of a transformer are schematically according to the invention ". The same reference numerals apply here as in FIG Circuit according to FIG. The three magnetic circuits q., 5 and 6 are next to each other arranged. On one side of the front side there is a fixed scattering surface 14. and on the other side a movable Streujoch 13, for example on two levers 15 and 16 is attached to the order. points 17 and 18 are pivotable. With help an adjusting device not shown in the figure (for example screw spindle) you can approach the scattering 13 the magnetic circuits q., 5 and 6 as desired and so the The scattering and thus the electrical data of the scattering transformer change.

Die Erfindung ,beschränkt sich nicht, wie dargestellt, auf Dreiphasenstrom, sondern kann sinngemäß auch bei. mehrphasigen Stromarten angewandt werden. Ein Anwendungsbereich ist das Gebiet der Schweißgleichrichter. Hier sind Stromregelungen in weiten Grenzen notwendig.The invention is not limited, as shown, to three-phase electricity, but can also be used analogously at. multiphase currents can be used. An area of application is the field of welding rectifiers. Here, current controls are within wide limits necessary.
