Description

Regeltransformator mit verschiebbaren Eisenkernen Gegenstand der Erfindung ist ein Regeltransformator mit verschiebbaren Eisenkernen, bei dem eine Primärwicklung in zwei magnetischen Kreisen zwei Flüsse konstanter Gesamtgröße erzeugt, die durch zunehmenden Widerstand in dem einen magnetischen Kreis und gleichzeitig um denselben Betrag abnehmenden Widerstand in dem anderen magnetischen Kreis oder umgekehrt mit Hilfe der verschiebbaren Eisenkerne regelbar sind. Erfindungsgemäß sind zwei voneinander unabhängige magnetische Kreise vorgesehen, auf die je eine Primär- und Sekundärwicklung aufgebracht ist, von denen die Primärwicklungen in Reihe und die Sekundärwicklungen gegeneinandergeschaltet sind. Mit einem solchen Transformator ist es möglich, die Sekundärspannung kontinuierlich zu regeln. Gegenüber bekannten Anordnungen besteht der Vorteil, daß die Streuung bei Belastung des Transformators eine geringere ist.Control transformer with sliding iron cores the subject of the invention is a regulating transformer with movable iron cores with a primary winding in two magnetic circuits two fluxes of constant total magnitude are generated, passing through increasing resistance in and around the one magnetic circuit Amount decreasing resistance in the other magnetic circuit or vice versa with With the help of the sliding iron cores, they can be regulated. According to the invention are two of each other independent magnetic circuits are provided, on each of which a primary and secondary winding is applied, of which the primary windings in series and the secondary windings are switched against each other. With such a transformer it is possible to achieve the Secondary voltage to be regulated continuously. Compared to known arrangements the advantage that the spread is less when the transformer is loaded.

In der Zeichnung ist die Erfindung an einem Beispiel veranschaulicht. Es sind zwei Eisenkerne io und 2o vorgesehen, die je einen Luftspalt senkrecht zur Flußrichtung . aufweisen. Jedem Luftspalt ist ein verschiebbares Blechpaket 8 bnv. 9 zugeordnet. Die beiden Blechpakete sind miteinander mechanisch verbunden. Bei der Verschiebung wird der magnetische Widerstand des einen Eisenkernes vergrößert und der des zweiten verkleinert. Auf den beiden Eisenkernen befinden sich die Primärwicklungen 4i und 42 gleicher Windungszahl; sie sind in Reihenschaltung an das speisende Netz angeschlossen. Die Sekundärwicklungen 5 und 6 sind gegeneinandergeschaltxt und in die eine Leitung des speisenden Netzes eingeschaltet, so daß der Transformator als Zusatztransformator wirkt. Befinden sich die Blechpakete 8 urid 9 beispielsweise in der linken Endstellung, so. ist der magnetische Widerstand im Eisenkern io klein, im Kern 20 sehr groß. Dies hat zur Folge, daß fast die gesamte Primärspannung an der Wicklung 4I liegt und daß dementsprechend vorn den beiden gegeneinandergeschalteten Sekundärwicklungen die Wicklung 5 ihre Maximalspannung entwickelt, während in der Wicklung 6 fast keine Spannung induziert wird. Der Transformator liefert daher seine maximale Sekundärspannung. Befinden sich die Blechpakete 8 und 9 in der rechten Endstellung, dann wird in der Sekundärwicklung 6 eine Maximalspannung induziert, während die Sekundärwicklung 5 fast spannungslos ist. Der Transformator entwickelt daher eine entgegengesetzt gerichtete maximale Sekundärspannung. Zwischen diesen beiden Endspannungen ist der Transformator durch Verschiebungder Blechpakete 8 und 9 kontinuierlich regelbar.The invention is illustrated using an example in the drawing. There are two iron cores io and 2o provided, each with an air gap perpendicular to the Direction of flow. exhibit. Each air gap is a movable laminated core 8 bnv. 9 assigned. The two laminated cores are mechanically connected to one another. at the displacement increases the magnetic resistance of one iron core and that of the second reduced. The primary windings are located on the two iron cores 4i and 42 with the same number of turns; they are connected in series to the feeding network connected. The secondary windings 5 and 6 are mutually connected and in the one line of the feeding network switched on, so that the transformer as Additional transformer works. Are the laminated cores 8 and 9, for example in the left end position, like this. if the magnetic resistance in the iron core is small, very large in core 20. As a result, almost all of the primary voltage is applied the winding 4I is and that accordingly the front of the two mutually connected Secondary windings the winding 5 develops its maximum voltage while in the Winding 6 almost no voltage is induced. The transformer therefore delivers its maximum secondary voltage. Are the laminated cores 8 and 9 in the right End position, then a maximum voltage is induced in the secondary winding 6, while the secondary winding 5 is almost dead. The transformer evolved therefore an oppositely directed maximum secondary voltage. Between these both end voltages is the transformer by shifting the laminated cores 8 and 9 continuously adjustable.
