Description

Einphasen-Schweißtransformator der Kerntype Es sind Einphasen-Schweißtransformatoren der Kerntype bekannt, bei denen die getrennten Primär-und Sekundärspulen auf beiden Schenkeln des Kerns liegen und in einer Ebene senkrecht zu den Kernblechen zwischen den Primär- und Sekundärspulen ein magnetischer Nebenschluß parallel zu sich selbst mittels einer Spindel verschiebbar ist. Der magnetische Nebenschluß ist in parallelen Schienen geführt, die mit Traversen verschraubt sind, die auch der Spindel als Führung dienen. Die Traversen sind mit Winkelschienen starr verbunden, die auf den Jochen des Eisenkerns liegen und mittels Spannschrauben die Kernbleche zusammenpressen. Die Schenkelbleche hingegen werden mittels Spannbolzen zusammengehalten, die durch Bohrungen der Kernschenkel zwischen den Primär- und Sekundärspulen hindurchgeführt sind. Diese Bohrungen stellen eine unerwünschte Verminderung des magnetischen Querschnitts des Eisenkerns dar. Die Erfindung bezweckt die Beseitigung dieses Nachteils. Zu diesem Zweck sind nach der Erfindung die Führungsschienen des magnetischen Nebenschlusses durch Traversen verbunden, die mittels Druckstücken die Bleche des Eisenkernes des Transformators zusammenpressen. Da gleichzeitig damit eine kraftschlüssige Verbindung der Traversen mit dem Eisenkern geschaffen ist, fallen besondere Verbindungs- und Befestigungsmittel der Traversen mit den Spannwinkeln der Joche fort. Hierdurch wird der Zusammenbau des Transformators erheblich vereinfacht und verbilligt.Core type single-phase welding transformers They are single-phase welding transformers The core type is known where the primary and secondary coils are separate on both Legs of the core lie and in a plane perpendicular to the core laminations between the primary and secondary coils have a magnetic shunt parallel to themselves is displaceable by means of a spindle. The magnetic shunt is in parallel Guided rails that are screwed to traverses, which also serve as a guide for the spindle to serve. The traverses are rigidly connected with angle rails that are on the yokes of the iron core and press the core sheets together using tensioning screws. The leg plates, on the other hand, are held together by means of clamping bolts, which are held by Bores in the core legs passed through between the primary and secondary coils are. These bores represent an undesirable reduction in the magnetic cross section of the iron core. The invention aims to eliminate this disadvantage. to according to the invention, the guide rails of the magnetic shunt are for this purpose connected by traverses that press the metal sheets of the iron core of the Press the transformer together. Since at the same time it is a force-fit connection the truss with the iron core is created, fall special connection and Fastening means of the crossbars continue with the clamping brackets of the yokes. Through this the assembly of the transformer is considerably simplified and cheaper.

Die Zeichnung stellt ein Ausführungsbeispiel der Erfindung dar, und zwar Fig. 1 eine Seitenansicht, teilweise im Schnitt nach der Linie A -B der Fig. 2, und Fig. 2 eine Teilaufsicht auf die obere Traverse. Auf die Ober- und Unterseite der Kernschenkel 1 sind in üblicher Weise Druckplatten 2 gelegt. Zwischen ihnen und den Traversen 9 sind Druckstücke 3 eingesetzt. Die Führungsschienen 4 für den Nebenschluß enden in Schraubbolzen 5, die durch die Traversen hindurchgesteckt und mittels Muttern 6 mit den Traversen verschraubt sind. Diese Muttern sind zugleich die Spannelemente, welche die Druckstücke 3 gegen die Druckplatten 2 und damit gegen die Schenkel 1 drücken. Mit 7 sind Spannplatten bezeichnet, welche die Vorder- und Rückseite des Nebenschlusses abdecken und die hintereinandergeschichteten Bleche des Nebenschlusses zusammenpressen. Der Nebenschluß ist in zwei Hälften geteilt, die auf der Vorder- und Rückseite eines Trägers 8 befestigt sind, durch welchen die Spindel 11 hindurchführt. Die Spindel wird durch Drehen der Verstellmutter 10 gehoben und gesenkt.The drawing shows an embodiment of the invention, namely Fig. 1 is a side view, partly in section along the line A-B of Fig. 2, and Fig. 2 is a partial plan view of the upper cross member. On the top and bottom of the core leg 1 pressure plates 2 are placed in the usual way. Pressure pieces 3 are used between them and the cross members 9. The guide rails 4 for the shunt end in screw bolts 5 which are inserted through the crossbars and screwed to the crossbars by means of nuts 6. These nuts are also the clamping elements which press the pressure pieces 3 against the pressure plates 2 and thus against the legs 1. With 7 clamping plates are designated, which cover the front and back of the shunt and press together the laminated sheets of the shunt. The shunt is divided into two halves, which are attached to the front and back of a carrier 8 through which the spindle 11 passes. The spindle is raised and lowered by turning the adjusting nut 10.
