Description
Die Erfindung bezieht sich auf eine Anordnung zur Erzeugung von elektrischem Strom für Lichtbogenschweißen.The invention relates to an arrangement for generating electrical power for arc welding.
Es sind Einrichtungen zum Erzeugen von elektrischem Strom für das Lichtbogenschweißen bekannt, bei denen die Ankerwicklung eines Dynamos mit einem Kollektor zur Entnahme, von Gleichstrom und mit Schleifringen zur Entnahme von Wechselstrom versehen istThey are devices for generating electrical power for arc welding known, in which the armature winding of a dynamo with a collector for removal, of direct current and is provided with slip rings for the extraction of alternating current
ίο und die Wechselspannung zeitweise in Serie mit der Gleichspannung zum Zweck des Ziehens des Lichtbogens geschaltet wird. Dazu ist in dem Schweißstromkreise ein Schalter eingebaut.ίο and the alternating voltage temporarily in series is switched with the DC voltage for the purpose of drawing the arc. In addition a switch is built into the welding circuit.
i-5 Demgegenüber kennzeichnet sich die Erfindung
durch eine Einrichtung der obengenannten Art, bei der statt eines Schalters ein
Transformator vorgesehen ist, dessen Sekundärwicklung dauernd im Schweißstromkreise
liegt und dessen Primärwicklung über einen vom Schweißstrom betätigten Schalter an die
Schleifringe des Generators angeschlossen ist. Diese Anordnung hat gegenüber der bekannten
insbesondere den Vorteil, daß der Sohweiß-Stromkreis niemals unterbrochen wird, einerlei,
ob es sich um das Ziehen des Lichtbogens oder um den normalen Schweißvorgang handelt.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist in der Zeichnung dargestellt;
es zeigt Abb. ι den Schaltplan der Anlage.In contrast, the invention is characterized by a device of the type mentioned above, in which a transformer is provided instead of a switch, the secondary winding of which is permanently in the welding current circuit and the primary winding of which is connected to the slip rings of the generator via a switch operated by the welding current. This arrangement has the particular advantage over the known one that the welding circuit is never interrupted, regardless of whether it is the drawing of the arc or the normal welding process.
An exemplary embodiment of the subject matter of the invention is shown in the drawing; it shows Fig. ι the circuit diagram of the system.
Ein Generator, der, wie gezeigt, eine Maschine mit Nebenschlußerregung oder eine Compoundmaschine sein kann, besitzt nur einen Anker, dessen Wicklung sowohl mit einem Kollektor 11 als auch mit Schleifringen 12 verbunden ist. Der Kollektor ii ist mit einer beweglichen Elektrode 13 und einem Werkstück 14 verbunden, das die andere Elektrode darstellt. Die Schleifringe 12 sind mit der Primärwicklung 15 eines Transformators verbunden, dessen sekundäre Wicklung 16 dauernd in Reihe mit dem Schweißstromkreis geschaltet ist. In dem Stromkreis der primären Wicklung 15 des Transformators befindet sich ein Schalter 17, der elektromagnetisch geöffnet wird, sobald der Lichtbogen gebildet ist. Die Antriebsspule 18 des Schalters wird durch unmittelbare Stromzuführung oder sonstwie erregt. 21 ist ein Aus- 5c gleichswiderständ.A generator which, as shown, is a machine with shunt excitation or a compound machine, has only one armature, its winding with both a collector 11 as well as with slip rings 12 is connected. The collector ii is with a movable electrode 13 and a workpiece 14 connected, the other Represents electrode. The slip rings 12 are connected to the primary winding 15 of a transformer connected, the secondary winding 16 of which is permanently in series with the welding circuit is switched. In the circuit of the primary winding 15 of the transformer there is a switch 17, which is electromagnetically is opened as soon as the arc is formed. The drive coil 18 of the Switch is excited by direct power supply or otherwise. 21 is an Aus 5c equal resistance.
Die Sekundärwicklung des Transformators stellt eine Drosselspule dar, und der Transformator besitzt eine solche magnetische Strömung, daß ein Teil mit einem verhältnismäßig geringen Strom durch die Sekundärwicklung gesättigt wird.The secondary winding of the transformer is a choke coil, and the transformer possesses such a magnetic flow that a part with a relatively low current through the secondary winding is saturated.
