Abstract
Die Erfindung betrifft ein Verfahren zum Herstellen eines rissfesten Gießharztransformators, wobei ein Gießharz zur elektrischen Isolation eines Wicklungskörpers des Gießharztransformators verwendet wird. Des Weiteren betrifft die Erfindung einen Gießharztransformator mit einer aus Gießharz bestehenden elektrischen Isolation eines Wicklungskörpers des Gießharztransformators. Durch Zugabe eines Zähigkeitsmodifikators von bis zu 20 phr ("parts per hundred resin") zum flüssigen Gießharz in Verbindung mit der Zugabe eines Beschleunigers, wird im Falle eines abgestimmten Härtungsprozesses durch linear oder treppenförmig aufsteigende Temperaturprofile die Rissfestigkeit des Gießharzes und damit die Lebensdauer des Gießharztransormators nachhaltig erhöht.The invention relates to a method for producing a crack-resistant cast-resin transformer, wherein a casting resin for electrical insulation of a winding body of the cast-resin transformer is used. Furthermore, the invention relates to a cast-resin transformer with an existing of cast resin electrical insulation of a winding body of the cast resin transformer. By adding a toughener modifier of up to 20 phr (parts per hundred resin) to the liquid casting resin in conjunction with the addition of an accelerator, in the case of a co-ordinated hardening process by linear or staircase rising temperature profiles, the crack resistance of the casting resin and thus the life of the cast resin transformer sustained increase.
