Description
Lichtbogenschweißtransformator mit Regelung des Spannungsabfalles Die Erfindung betrifft eine neue Anordnung der bewegten Spulen bei solchen Schweißtransformatoren, welche durch Änderung des Abstandes der sekundären von der primären Spule geregelt werden.Arc welding transformer with voltage drop regulation The invention relates to a new arrangement of the moving coils in such welding transformers, which is regulated by changing the distance between the secondary and the primary coil will.
Die Zeichnung stellt ein Ausführungsbeispiel dar. Hier ist die Sekundäre als beweglich angenommen, es kann aber auch die Primäre beweglich sein. Wie die' Zeichnung erkennen läßt, ist die feststehende Spule, hier die Primäre, in zwei Spulen P1 und P2 geteilt, welche sich an je einem Ende des Kernes K befinden. Als Transformator ist hier die Mantelform, aus zwei Kerntransformatoren gebildet, dargestellt. In der zwischen den beiden Kernen K1 und K2 gebliebenen Spalte befindet sich .eine Spindel B, welche in der einen Hälfte linksgängig, in der andern rechtsgängig ist. Sie dient zur Verstellung der beiden. Sekundärhälften S1 und S2. Bei Drehung der Spindel nähern oder entfernen sich also die beiden Sekundärhälften voneinander. Ist dex Transformator auf höchste Leistung eingestellt, so befinden sich beide Sekundärhälften in der Nähe der Primären. Da aber solche Transformatoren immer so disponiert sind, daß auch bei Höchstleistung noch Raum zwischen Primäre und Sekundäre bleibt, sind durch die Anordnung die Abkühlungsflächen gegenüber den alten Anordnungen mit einer nicht unterteilten Spule verdoppelt.The drawing shows an embodiment. Here is the secondary assumed to be mobile, but the primary can also be mobile. As the' The drawing shows that the stationary coil, here the primary one, is in two coils P1 and P2 divided, which are each located at one end of the core K. As a transformer the shell shape, formed from two core transformers, is shown here. In the gap remaining between the two cores K1 and K2 is .eine Spindle B, which is left-handed in one half and right-handed in the other. It is used to adjust the two. Secondary halves S1 and S2. When rotating the The two secondary halves approach or move away from each other on the spindle. If the dex transformer is set to maximum output, both secondary halves are located near the primary. But since such transformers are always so arranged, that there is still space between primary and secondary even at maximum performance by the arrangement the cooling surfaces compared to the old arrangements with a not subdivided coil doubled.
Der Transformator kann also höher belastet werden, und die Anordnung wirkt so Baustoff sparend. Erst bei der kleinsten Leistung liegen die Sekundärhälften zusammen wie bei der nicht unterteilten Spule, dann ist aber die Belastung klein.The transformer can therefore be loaded higher, and the arrangement thus saves building material. The secondary halves are only located at the lowest output together as with the non-subdivided coil, but then the load is small.
