PURPOSE:To alleviate the uneven electric field, by extending winding support plates of lower tightening metal facing ends of wirings, shielding the space between the ends of wirings and the lower parts of a yoke, and arranging the extended end surfaces in opposing positions with a space being provided. CONSTITUTION:Over a sharp edge 21 of iron-core yoke facing a high voltage winding end 51a and a low voltage winding end 52a, U-shaped supporting plates 41 and 42 for winding 51 and 52 are provided, and plates 45 and 46 are provided by extending the supporting plates 43 and 44. The plate 45 and 46 are faced to each other at the center of the top surface of the yoke. Plates 45a and 46a are extended outward on the core legs. The electlic field at the ends of the tightening metals are alleviated, and the coil is effectively supported. Sharp edges are not provided at the portions where the spaces between the plates 45 and 46 and 45a and 46a face the windings. In this cinstitution, grounding electrodes electrically opposing the winding ends 51a and 52a constitute the flat-plate parts of the coretightening metal, and do not face the sharp edge 21 of the iron core yoke. Thus the uneven part of the electric field is removed. |
