Title: Winding insulation for toroidal core - forms rings at ends of core to assist free cooling oil circulation between turns
IPC: H01F17/06
Filed: 1978-12-04
Abstract: The insulation method is partic. applicable to ribbon wound toroidal cores for power transductors. The insulation is in the form of rings fitted at each end of the core. Each ring covers part of the radial end face and extends a short way along the axial length of the core. The toroidal coil is then wound around the core. The axial gap between the insulation rings causes a space under the winding which is available for cooling oil circulation. The insulation rings are typically made from strips of insulation material which have sloping slits along one edge extending roughly half way across the strip. When the uncut part is fitted to the axial surface of the core the slits permit the cut half to conform with the radial face.
