Description
Transformator zur Erhöhung der Phasenzahl. Für die Speisung von. Gleichrichtern mit sechs Anoden ist ein Sechsphasenstransforniator bekannt geworden, welcher durch Kombination einer Stern- und Sechseckschaltung eine bessere Stromverteilung unter den verschiedenen Phasen der Primärseite bewirkt.Transformer to increase the number of phases. For feeding. Rectifiers With six anodes, a six-phase transformer has become known, which by Combination of a star and hexagonal connection provides better power distribution the different phases of the primary side.
Mit der gleichen in Abb. i dargestellten Wicklungskombination auf dem Transforinator, wo oi, l'o, 23' und 32' vier gleiche Teile der Sekundärwicklung sind, welche der gleichen Phase des speisenden Dreiphasennetzes entsprechen, läßt sich gemäß der Erfindung durch an sich bekannte Anzapfungen an den Wicklungsteilen des Transformators die Speisung einer größeren "Zahl von Anoden mit einer gleichen Zahl von gleich weit auseinanderliegenden Phasen ermöglichen.With the same winding combination shown in Fig. I the transformer, where oi, l'o, 23 'and 32' are four equal parts of the secondary winding which correspond to the same phase of the feeding three-phase network according to the invention by known taps on the winding parts of the transformer the feeding of a larger "number of anodes with the same Allow number of equally spaced phases.
Abb.2 stellt die Anwendung auf den Fall der Speisung von 12 Anoden durch 12 Phasen lag. Die Anoden sind dabei nicht an die Ecken des Sechsecks, sondern an Punkte a, b. c, d der die Seiten des Sechsecks bildenden Sekundärwicklungen 13', 3'2 usw. angeschlossen, sc daß im Spannungs<iiagrainm, dargestellt durch die gleiche Abbildung, wo 01, 03', 02, oi' usf. den Spannungen der Ecken des Sechsecks im Verhältnis zum Nullpunkt entsprechen, die Punkte u, b, c, d usw. zusammen ein reguläres Polygon von 12 Seiten darstellen.Fig.2 shows the application in the case of 12 anodes being fed by 12 phases. The anodes are not at the corners of the hexagon, but at points a, b. c, d of the secondary windings 13 ', 3'2, etc. forming the sides of the hexagon are connected, sc that in the voltage <iiagrainm, represented by the same figure, where 01, 03', 02, oi 'etc. are the voltages of the corners of the Hexagons in relation to the origin, the points u, b, c, d etc. together represent a regular polygon of 12 sides.
Durch Hinzufügen von sechs zusätzlichen Anzapfungen in p, q, r auf den sterngeschalteten Wicklungen oi, o3' o2 usf. und durch Näherrücken der Anzapfungen a, b, c, d usw. auf den Sechseckseiten kann man auch 18 Phasen herstellen.By adding six additional taps in p, q, r on the star-connected windings oi, o3 'o2 etc. and by moving the taps a, b, c, d etc. closer to the hexagon sides, you can also create 18 phases.
Die Vermehrung der Phasenzahl ergibt eine Erhöhung der Gleichstromspannung bei gleichbleibender Maximalspannung zwischen Anoden, die Verniinderu -g der Schwankungen im deichgerichteten Strom und der höheren Harmonischen auf der Wechselstroniseite sowie eine Verminderung des Spannungsabfalls, also eine bessere Ausnutzung des Transformators.The increase in the number of phases results in an increase in the DC voltage with a constant maximum voltage between anodes, the reduction in the fluctuations in the dike-directed current and the higher harmonics on the alternating current side as well as a reduction in the voltage drop, i.e. better utilization of the transformer.
Die Anwendung von Gleichrichtern mit i.-#. oder 18 Phasen ist nicht
erforderlich, wenn man durch den gleichen Transformator gleichzeitig zwei oder drei
Gleichrichter zu sechs
