Description
Wandertransformatokren. größter Leistung und höchster Spannung sind nur als Einphasentypen ausführbar. Um die zur Verfügung stehende Bauhöhe weitgehend für die Wicklung auszunutzen, werden diese Transformatoren, in bekannter Weise mit magnetischen Rückschlüssen in Gestalt zweier Hilfsschenkel ausgeführt. Da, diese Transformatoren zum mindesten oberspannun:gsseitig mit starr geerdetem Nullpunkt ausgeführt werden, ist es vorteilhaft, diese Wicklung mit Anzapfungen für Umsteller oder Lastschalter auszurüsten. Bei größeren Abschaltungen ist hierfür eine Schaltspule vorzusehen, die die Stammwicklung der ganzen Länge nach überdeckt. Da die Stammwicklung elektrisch am Eingang, die, Schaltspule dagegen elektrisch am Nullpunkt liegt, sind beide gegeneinander für die volle ,Spannung zu isolieren, was einen- beträchtlichen. Aufwand an Raum und Geld erfordert.Traveling transformers. highest power and highest voltage only executable as single-phase types. To a large extent to the available height for the winding, these transformers are used in a known manner magnetic return circuits in the form of two auxiliary legs. This one Transformers at least overvoltage: on the side with rigidly earthed zero point are carried out, it is advantageous to have this winding with taps for changeover or to equip load switches. A switching coil is required for larger shutdowns to be provided that covers the trunk winding along its entire length. Since the trunk winding are electrical at the input, whereas the switching coil is electrically at the zero point both to isolate from each other for the full, voltage, what a- considerable. Requires space and money.
Die Erfindung bezweckt eine aus Einphasentransformatö,ren mit magnetischem Rückschluß, bestehende Anordnung zur Spannungsregelung, die diese, Nachteile nicht aufweist. Sie erreicht es dadurch, daß die Anzapfungsspule auf einem oder mehreren Rückschlußschenke@l(n) angebracht und mit der zugehörigen Stammwicklung in Reihe geschaltet ist. Zwei Ausführungsbeispiele gemäß der Erfindung sind in der Zeichnung dargestellt.The invention aims at a single-phase transformers with magnetic Conclusion, existing arrangement for voltage regulation that does not have these disadvantages having. You achieve it by having the tap coil on one or more Rückschlussschenke @ l (n) attached and in series with the associated main winding is switched. Two embodiments according to the invention are in the drawing shown.
Fig. I zeigt einen, Einphasentransformator mit reduzierten Jochen. Auf dem Schenkel i sind die primäre Wicklung 2 und die sekundäre Wicklung 3 aufgebracht. Der regelbare, und vorzugsweise geerdete Teil 4 der Oberspannungswicklung befindet sich auf dem Hilfsschenkel 5 bzw. auf den Hilfsschenkeln 5, 6. Die primäre Spannung wird an .den Klemmen 7, 8 zugeführt, während die geregelte Spannung an den Klemmen 11, 12 zur Verfügung steht. Fig. 2 zeigt einen Regeltransformator ähnlicher Bauweise, der jedoch als Vierschenkeltyp mit zwei bewickelten Hauptschenkeln ausgeführt ist. Die Bezeichnungen haben hier dieselbe Bedeutung wie, in Fig. i. Der Vorteil dieser Anordnung besteht darin, daß hier zwei gleich große oder nach Wahl zwei verschieden große unabhängige Stromkreise geschaffen werden, die einzeln ohne Rückwirkung aufeinander belastet werden können. Der hierdurch mögliche Gewinn durch Verwendung von: Schaltern kleiner Leistung ist beträchtlich. Die primäre Spannung wird an den Klemmen 7, 8 bzw. 9, io zugeführt, die geregelte Spannung wird an den Klemmen 11, 12 bzw. 11, 13 abgegriffen.Fig. I shows a single-phase transformer with reduced yokes. The primary winding 2 and the secondary winding 3 are applied to the leg i. The controllable, and preferably grounded, part 4 of the high-voltage winding is located on the auxiliary legs 5 or on the auxiliary legs 5, 6. The primary voltage is fed to terminals 7, 8, while the regulated voltage is available at terminals 11, 12 stands. Fig. 2 shows a regulating transformer of a similar design, but which is designed as a four-leg type with two main legs wound. The designations have the same meaning here as in Fig. I. The advantage of this arrangement is that here two independent circuits of the same size or optionally two different sizes are created which can be loaded individually without affecting one another. The possible gain by using low-power switches is considerable. The primary voltage is fed to terminals 7, 8 or 9, io, the regulated voltage is tapped at terminals 11, 12 or 11, 13.
