The SriluätHKg concerns a new form of a cast resin-cast winding for transformers and choke coils «
Es hat in der Vergan'gonheit nicht an Versuchen gefehlt, betriebssichere Transformatoren auch für mittlere Reihen mit■ in Gießharz eingegossenen Oberspannungswicklungen herzusteilen,» Der entsprechende Gießharzkörper muß, um die in der Wicklung entstehende Wärme bei erträglichem Aufwand ausrei-t chend abführen zu können, von Ktihlkanälen durchsetzt sein, was eine komplizierte Gießform erfordert. Die elektrische ■ Festigkeit an den kritischen Stellen an den lagen- oder Spulenenden wird bei den bekannten Ausführungsformen im all·? gemeinen von der Reihenschaltung Gießharz - luft bestimmt ' und erfordert daher entsprechend große· Abstände *There has been no shortage in the Vergan'gonheit of attempts herzusteilen reliable transformers for middle rows ■ cast resin molded high-voltage windings must "The corresponding cast resin to the resulting in the winding heat at acceptable effort suffi- t be able to remove accordingly, be penetrated by Ktihlkanäle, which requires a complicated mold. The electrical ■ strength at the critical points at the layer or coil ends is in the known embodiments in all ·? common by the series connection cast resin - air determined 'and therefore requires correspondingly large distances *

Eine gute Wärmeableitung und damit kleinere Gesamtabmessungen werden erreicht, wenn aadj^camg-ggemäß im öießharzkörper zwischen konzentrischen' Wicklungen bzw» Wicklungsteilen im Kreis angeordnete im Innenraum offene Rohre aus wärmeleitfähigem Material angeordnet und mit eingegossen sind*Good heat dissipation and thus smaller overall dimensions are achieved when aadj ^ camg-g according to the oleoresin body between concentric windings or parts of windings in a circle arranged in the interior open tubes made of thermally conductive material are arranged and cast in *
Eine noch bessere Wärmeableitung erfolgt, wenn die Rohre aus dem Gießharzkb'rper herausragen, so daß zusätzlich zur Wärmeabgabe durch Konvektion an den Kühlrohrenden beidseitig Wärme abgestrahlt wird* -An even better heat dissipation takes place if the tubes protrude from the cast resin body, so that in addition to the dissipation of heat heat is radiated on both sides by convection at the cooling tube ends * -
Eine Steigerung der elektrischen Sicherheit bei kleineren Abmessungen wird zusätzlich erreicht, wenn diese Rohre aus . einem Metall bestehen» Dadurch wird der Luftraum innerhalb der Kühlkänäle elektrisch kurzgeschlossen, so daß die ganze Potentialbeanspruchung allein im Gießharz auftritt, das eine wesentlich höhere elektrische Festigkeit als Luft oder die Kombination Gießharz - Luft besitzt.An increase in electrical safety with smaller dimensions is additionally achieved when these tubes are out. consist of a metal »This creates the air space within the cooling ducts are electrically short-circuited, so that the whole Potential stress occurs only in the cast resin, which has a much higher electrical strength than air or the Combination of cast resin - air.
Diese Metallkühlrohre können an das Potential der einen oder anderen Wicklung oder Wicklungsteiles oder an ein Mttelpotential angelenkt oder auch geerdet sein.These metal cooling tubes can be at the potential of one or the other other winding or winding part or to a medium potential articulated or grounded.
Sehr günstige Wärmsleiteigehschaften und infolge ähnlicher Wärmedehnungs-Koeffizienten ein gutes Verhalten im Verbund Gießharz - Rohr, weist Leichtmetall, insbesondere Aluminium auf. ■Very favorable heat conduction properties and, as a result, similar Coefficient of thermal expansion a good behavior in the composite Cast resin pipe comprises light metal, in particular aluminum. ■

Fig, 1 zeigt einen längsschnitt, Fig. 2 einen Querschnitt durch eine nach der Erfindung ausgebildeten Wicklung«. „Fig. 1 shows a longitudinal section, Fig. 2 shows a cross section by a winding designed according to the invention «. "
1 und 2 sind die beiden Wicklungen oder Wicklungsteile, die durch einen mit Lärigskühlkanälen 3 durchsetzten Gleßharzgttrtel getrennt sind* Zur besseren Wärmeleitung in längsrichtung sind diese Kühlkanäle mit Rohren 5 aus wärmeleitfähigem Material ausgekleidet*1 and 2 are the two windings or winding parts that through a Gleßharzgttrtel interspersed with Lärigskühlkanäle 3 are separated * For better heat conduction in the longitudinal direction, these cooling channels with tubes 5 are made of thermally conductive Lined material *
Besteht zwischen den beiden Wicklungsteilen 1 und 2 eine Potentialdifferenz, so wird eine Erhöhung der elektrischen· Festigkeit dadurch erreicht, daß mittels der aus Metall bestehenden Rohre 5, die sparinungsbeanspruchte Strecke mit der schlechteren elektrischen Festigkeit des Kühlmediums innerhalb der Rohre kurzgeschlossen ist»If there is one between the two winding parts 1 and 2 Potential difference, an increase in the electrical strength is achieved by means of the Pipes 5, the route subject to savings with the poorer electrical strength of the cooling medium is short-circuited within the pipes »
Durch geeignete Anordnung der metallischen Kühlrohre ist es außerdem möglich, eine Steuerung des elektrischen Feldes und damit eine bessere Isolierstoffausnützung zu erzielen* ·■ ■By suitable arrangement of the metal cooling pipes it is it is also possible to control the electrical field and thus achieve better utilization of the insulation material * · ■ ■
Eine gute räumliche Ausnutzung wird erreicht, wenn die Rohre oyalen Querschnitt oder oval gebogenen Querschnitt, wie die rechte Hälfte der Fig* 2 zeigt, erhalten.A good use of space is achieved if the pipes oval cross-section or oval-curved cross-section, like the right half of Fig * 2 shows obtained.
