Abstract (en)
[origin: WO2010060672A1] The invention relates to a holding device for fastening a cast resin transformer winding relative to a transformer core having a support element and a receiving element attached to a tie rod. By fastening the support element to the receiving element attached to the tie rod, a cast resin transformer winding can be fixed rigidly and precisely centered relative to a transformer core. By attaching the receiving element directly on the tie rod, circulation in the lower region of the cast resin transformer winding or of an insulating cylinder also attached to the support element is ensured and thereby the thermal properties of a cast resin transformer winding produced in this way are improved. Furthermore a modular and thus simple design of the cast resin transformer is possible due to the possibility of connecting the receiving element to the tie rod by way of the support element.
