Description

Hochspannungstransformator hoher Eigenkapazität Bei :elektrischen Transformatoren hoher Spannung, wie sie besonders für Prüfungszwecke und Versuche verwendet werden, verursacht die Eigenkapazität des Transformatorseinen beträchtlich voreilenden Leistungsfaktör, der eine .unverhältnismäßig große Maschinenanlage für diesen Betrieb :erfordert. Der Leistungsfaktor ändert sich in weitem Umfange mit der Frequenz, mit der bei den Versuchen gearbeitet werden muß, und wird des weiteren durch die Kapazität der Versuchsobjekte beeinflußt.High voltage transformer with high self-capacitance For: electrical High voltage transformers, such as those used especially for testing purposes and experiments are used, the self-capacitance of the transformer causes its considerable leading power factor, which is a disproportionately large machine system for this operation: required. The power factor changes to a large extent the frequency with which the experiments must be carried out, and will furthermore influenced by the capacity of the test objects.

Zweck der Erfindung ist, eine Verringerung des in derartigen Anlagen auftretenden, voreilenden Blindstromes zu erreichen. Erfindungsgemäß wird in einem solchen Hochspannungstransformator der magnetische Kreiss für veränderlichen magnetischen Widerstand eingerichtet, wodurch der benötigte Blindstrom bei den verschiedenen, sich ändernden Gebrauchsbedingungen des Transformators so gering wie möglich gehalten werden kann.The purpose of the invention is to reduce the energy consumption in such systems occurring, leading reactive current to achieve. According to the invention in one such high voltage transformer the magnetic circuit for variable magnetic Resistance set up, whereby the required reactive current for the different, changing conditions of use of the transformer kept as low as possible can be.

Die Erfindung ist in den Zeichnungen beispielsweise dargestellt.The invention is illustrated in the drawings, for example.

Abb. i zeigt eine Ansicht des Transformatoreisenkörpers gemäß der Erfindung, Abb. 2 eine Seitenansicht dazu. Abb.3 stellt einen Teil des Querschnitts und Abb. ¢ eine Seitenansicht des in ein Gehäuse eingeschlossenen Transformators dar. Abb.5 endlich zeigt eine geeignete Steuervorrichtung für einen von der Erde isolierten Transformator.Fig. I shows a view of the transformer iron body according to FIG Invention, Fig. 2 is a side view thereof. Fig.3 represents part of the cross-section and Fig. ¢ a side view of the transformer enclosed in a housing Fig.5 finally shows a suitable control device for one from the earth isolated transformer.

Gemäß Abb. i bis 3 wird das Jochende b des Eisenkörpers beweglich gemacht, so daß sich der Luftzwischenraum, je nach den Umständen, unter welchen der Transformator zu einer gewissen Zeit gebraucht wird, verändern läßt. Die Bewegung des Jochendes b wird durch Schrauben c herbeigeführt, die in dem Gewinde der starr mit dem Jochende verbundenen Platte d angreifen. Die Schrau-ben c sind mit Halsstücken e und Muttern f versehen, welche die Schrauben in ihren Lagerng halten, und jede -Schraubenspindel trägt eine Rolle h. Eine endlose Kette n ver- bindet die beiden Rollen, und eine verschiebbare Rolle k dient zur Aufrechterhaltung der Kettenspannung. Die eine der Rollen ist durch eine Kupplung j mit einer Spindel L verbunden, .die mittels einer Stopfbüchse m durch die Gehäusewand geführt ist.According to Fig. I to 3, the yoke end b of the iron body is made movable so that the air gap, depending on the circumstances under which the transformer is needed at a certain time, can be changed. The movement of the yoke end b is brought about by screws c which engage in the thread of the plate d rigidly connected to the yoke end. The screws c are provided with neck pieces e and nuts f which hold the screws in their bearings, and each screw spindle carries a roller h. An endless chain n connects the two rollers, and a movable roller k is used to maintain the chain tension. One of the rollers is connected by a coupling j to a spindle L, which is guided through the housing wall by means of a stuffing box m.

Die im obigen beschriebenen Mittel zur Bewegung des Transformatorjoches ermöglichen eine veränderliche Einstellung .des magnetischen Widerstandes des magnetischen Kreises.The means described above for moving the transformer yoke allow a variable setting of the magnetic resistance of the magnetic Circle.

Die Erfindung bietet besondere Vorteile bei Kaskadentransformatoren. In diesem Falle können einer oder alle der Reihentransformatoren mit magnetischen Kreisen von veränderlichen magnetischen, Widerstand versehen sein. Wenn eine Veränderung der Einstellung bei eingeschaltet= Transformator gewünscht wird, müssen isolierte Handgriffe für Betätigung der Wellen vorgesehen werden. Die beweglichen Eisenteile des Kernes oder des Joches müssen selbstverständlich derart gelagert .sein, daß die in dem magnetischen Kreis etwa auftretenden Verschiebungskräfte in geeigneter Weise durch die Einstellungseinrichtung aufgenommen werden. Ein Ausführungsbeispiel des Erfindungsgegenstandes in Anwendung auf einen Kaskadentransformator ist in Abb. 5 gezeigt, bei dem die Spindel L vermittels .eines Universalgelenks g und eines Rohrs r von einer mit einem Handrad p ausgerüsteten Steuersäule aus, betätigt wird.The invention offers particular advantages in cascade transformers. In this case, one or all of the series transformers with magnetic Circles of variable magnetic, resistance to be provided. When a change the setting when switched on = transformer is required must be isolated Handles for operating the shafts are provided. The moving iron parts of the core or the yoke must of course be stored in such a way that the displacement forces occurring in the magnetic circuit in a suitable manner Manner can be recorded by the setting device. An embodiment The subject of the invention applied to a cascade transformer is shown in Fig. 5 shown, in which the spindle L by means of .ein universal joint g and one Rohrs r is operated from a control column equipped with a handwheel p.
