Description
Die Erfindung richtet sich, auf einen Transformator zum Schweißen und Schneiden mit tels des elektrischen Lichtbogens.The invention is directed to a transformer for welding and cutting with means of the electric arc.
Für diese Zwecke sind Transformatoren bekannt, deren magnetischer Kreis aus zwei Spulenkernen und zwei durchgehenden Jochen besteht, wobei die Primärwicklung und ein Teil der Sekundärwicklung auf dem gleichen Kern, der Rest der Sekundärwicklung auf dem zweiten Kern untergebracht sind. Zur Abkürzung seien der erste Teil der Sekundärwicklung als .Hauptsekundärwicklung, der Rest als Hilfssekundärwicklung bezeichnet.For this purpose transformers are known whose magnetic circuit consists of two Coil cores and two continuous yokes, with the primary winding and one Part of the secondary winding on the same core, the rest of the secondary winding on the second core are housed. For the sake of brevity, let us consider the first part of the secondary winding as .Main secondary winding, the rest referred to as auxiliary secondary winding.
Gemäß der Erfindung ist bei derartigen Transformatoren zum Schweißen und Schneiden mittels des elektrischen Lichtbogens ein dritter, durch Luftspalte von den Jochen abgetrennter Kern zwischen Verlängerungen der Joche außerhalb der Spulenkerne gelegen, ao Hierdurch wird trotz der Verwendung des durch Luftspalte abgetrennten Kernes ein kurzer magnetischer Kreis ermöglicht.According to the invention, such transformers are for welding and cutting by means of the electric arc, a third one, separated from the yokes by air gaps Core located between extensions of the yokes outside the coil cores, ao This makes a short one despite the use of the core separated by air gaps magnetic circuit enables.
Zwecks Regelung seiner Wirkung läßt sich der als magnetischer Nebenschluß dienende dritte Eisenkern gegenüber dem Rahmen des Transformators vorzugsweise beweglich ausbilden. In order to regulate its effect, the one serving as a magnetic shunt can be used Form the third iron core preferably movable relative to the frame of the transformer.
Auf der Zeichnung ist die Erfindung in einem Ausführungsbeispiel dargestellt; die Abbildung ist eine schematische SMzze der Eisenteile und Wicklungen des Transformators. In the drawing, the invention is shown in one embodiment; the illustration is a schematic diagram of the iron parts and windings of the transformer.
Der magnetische Kreis setzt sich aus den Spulenkernen 1 und 2 und den die beiden Kerne verbindenden Jochen 3 zusammen. Auf dem Kern 1 befindet sich die Primärwicklung 4, die an eine Wechselstromquelle angeschlossen wird. Die Hauptsekundärwicklung s liegt gleichfalls auf dem Kern i, während die Hilfssekundärwicklung 6 auf dem Kern 2 untergebracht ist. Sämtliche Spulen können mit Anzapfungen versehen sein, an die sich die Stromquelle bzw. die zu den Elektroden führenden Leitungen 7 und 8 bzw. die Verbindung 11 zwischen Haupt- und Hilfssekundärwicklung nach Belieben anschließen läßt.The magnetic circuit is made up of the cores 1 and 2 and the two Cores connecting yokes 3 together. The primary winding is located on core 1 4 connected to an AC power source. The main secondary winding s is also on the core i, while the auxiliary secondary winding 6 is accommodated on the core 2. All coils can be provided with taps to which the power source or the lines 7 and 8 leading to the electrodes or the connection 11 between main and auxiliary secondary winding can be connected at will.
Erfindungsgemäß sind die Jocjue 3 nach außen verlängert, 9, und zwischen den Verlängerungen 9 liegt, durch Luftspalte getrennt, ein dritter Kern 10, der als Nebenschluß von Joch zu Joch wirkt. Der Erfindungsgedanke wird gewahrt, wenn der dritte Kern 10 vor den Köpfen der verlängerten Joche 9 liegt. In diesem Fall wirkt der Kern ebenfalls als magnetischer Nebenschluß zwischen den verlängerten Jochen. Wird zwecks Regelung der Nebenschlußwirkung Verstellbarkeit des Kernes 10 gewünscht, so läßt sich das mit bekannten Mitteln auf beliebige Weise erreichen. Auf die Art dieser Bewegung kommt es nicht an; sie kann sowohl eine geradlinige als auch eine Drehbewegung sein.According to the invention, the Jocjue 3 are after extended on the outside, 9, and between the extensions 9, separated by air gaps, a third core 10 which acts as a shunt from yoke to yoke. The idea of the invention is preserved when the third core 10 is in front of the heads of the extended yokes 9. In this case the core also acts as a magnetic shunt between the elongated ones Yokes. If adjustability of the core 10 is desired for the purpose of regulating the shunt effect, this can be done with known ones Reach funds in any way. The nature of this movement does not matter at; it can be both a straight line and a rotary motion.
Auf den Jochen lassen sich Windungen 12 der Sekundärwicklung anbringen, die als Beruhigungswicklung dienen können.Turns 12 of the secondary winding can be attached to the yokes, which act as calming windings can serve.
