Description

Giessharzwandler. Cast resin converter.

Dadurch, dass bei Giessharzwandlern der die Wicklung umkleidende Giessharzkörper gleichseitig als Schlagweitenteil dient, ist eine kleinere Bauhöhe als bei den Wandlern erreichbar, bei denen z. B. Ölisolierung und Porzellanisolatoren als Schlagweitenteil verwendet werden.This is because, in the case of cast resin converters, the cast resin body enclosing the winding serves at the same time as a throwing distance part, is a smaller overall height than the transducers achievable where z. B. Oil insulation and porcelain insulators as pitch range part be used.

Bei einem Vergleich des Raumbedarfs eines Wandlers mit Schenkelkern und desjenigen eines Wandlers mit Mantelkern weist der Mantelkernwandler einen kleineren Raumbedarf auf als der Schenkelkernwandler ; der Mantelkernwandler besitzt allerdings hierbei eine kürzere Schlagweite vom Hochspannungsanschluss zum geerdeten Eisenkern. Man hat daher, um die erforderliche Schlagweite ohne Vergrösserung der andlerhöhe zu erhalten, bereits den Giessharzkörper über den Kernumfang heruntergezogen.When comparing the space requirements of a transducer with a leg core and that of a clad-core transducer, the clad-core transducer has a smaller one Space requirement on than the leg core transducer; the clad core converter, however, has here a shorter distance from the high-voltage connection to the earthed iron core. You therefore have to reach the required striking distance without increasing the andlerhöhe to get, the cast resin body has already been pulled down over the core circumference.

Dadurch nehmen die Länge und die Breite des Wandlers je um die doppelte Stärke des zur Verlängerung der Schlagweite heruntergezogenen Giessharzteiles zu. Um dieser Vergrößerung, z. B. hinsichtlich der Breite des Wandlers, zu begegnen, hat man anstelle eines Mantelkernes gewissermassen eine Nachbildung eines solchen Kernes vorgeschlagen ; diese Nachbildung besteht aus zwei rahmenförmigen Eisenkernen ; der die Wicklung tragende Mittelschenkel wird von je einem Schenkel der beiden Rahmenkerne gebildet ; zur Verringerung der Breite hat man dann die Ebenen der beiden Rahmenkerne unter einem Winkel von vorzugsweise etwa 900 zueinander angeordnet.As a result, the length and the width of the transducer each double Thickness of the cast resin part pulled down to extend the striking distance. To this magnification, z. B. with regard to the width of the transducer, instead of a sheath core, one has to a certain extent a replica of one Suggested kernes; this replica exists from two frame-shaped Iron cores; the middle limb carrying the winding is supported by one limb formed by the two frame cores; then to reduce the width you have the planes of the two frame cores arranged at an angle of preferably approximately 900 to one another.

Eine solche Ausbildung erfordert eine mehrfache Abstufung der Blechschichten des Kernes, also entsprechend viele Blechschnittformen.Such a training requires a multiple gradation of the sheet metal layers of the core, i.e. a corresponding number of sheet metal cut shapes.

Um das zu vermeiden, wird neuerungskemäss ein anderer Weg beschritten, der dadurch gekennzeichnet ist, dass der Giessharzwandler mit einem gebogenen Mantelkern ausgerüstet ist.In order to avoid this, a different path is being pursued, which is characterized in that the cast resin converter has a curved jacket core is equipped.

In den Figuren 1 und 2 sind zwei Ausführungsformen eines derart ausgerüsteten Giessharzwandlers wiedergegeben. Bei diesem Giessharzwandler wird nach Herstellung des Giessharzkörpers 1 im Umguss um die z. B. konzentrisch angeordnete Primär-und Sekundärwicklung in den Querdurchgang der gebogene Mantelkern 2 z. B. in üblicher Weise eingeschachtelt. In FIGS. 1 and 2, two embodiments of a cast resin converter equipped in this way are shown. In this cast resin converter is after production of the cast resin body 1 in the encapsulation around the z. B. concentrically arranged primary and secondary windings in the transverse passage of the curved jacket core 2 z. B. boxed in the usual way.

Zur weiteren Verringerung der Breite kann man die Stegbreite der Kernbleche verkleinern und dafür die Höhe der Schichtung grösser machen. Dann ist es zweckmässig, die Wicklungen oval auszubilden.The web width of the core sheets can be used to further reduce the width reduce and increase the height of the stratification. Then it is useful to form the windings oval.
