PURPOSE:To prevent the generation of corona discharge in the edge par of a discharge fixing plate by connecting a winding finish end and a winding start end in an intermediate par of the winding layer facing a cooling duct of the coil blocks of a parallel winding high voltage side coil to the outermost end part in axis direction of the potential fixing plate respectively. CONSTITUTION:Coil blocks 7a, 7b, 8a and 8b divided into inside and outside one by a cooling duct 14, the winding finish end and the winding start end facing the cooling duct 14 par are wound in a manner they are coated on the outermost end in axial direction of the coil blocks 7 and 8. Among them, the finishing ends of the inside coil blocks 7a and 8a are connected to one side of the outermost end parts (c) of the second potential fixing plate 15 and the starting end of the outside wire lop blocks 7b and 8b are connected to another side of outermost end parts (d) of the plate 15. Accordingly, the finishing ends of the blocks 7a and 8a and the starting ends of the blocks 7b and 8b are kept at nearly the same potentials. In this constitution, the second potential fixing plate 15 is at the same potential as the winding finish ends and the start ends of the inside and outside coil blocks 7a, 8b, 8a, and 8b. |
