    摘要： The doughnut-type transformer comprises a spirally wound core consisting of several individual annular cores each tightened by rod members. The annular core is surrounded by transformer sections comprising the primary and the secondary windings. Each winding is composed of turns shaped as sectors in the plane of the transformer cross-section, a cooled turn of the secondary winding being placed between the turns of the primary winding in each transformer section. The turns of the windings surround the annular core so that the geometric center of each winding is displaced from the geometric center of the annular core in the cross-sectional plane thereof and the geometric center of the annular core is farther from the transformer axis. Each turn of the secondary winding is provided with a passage for cooling water to circulate therethrough, which water being supplied and discharged through one and the same contact ring and is first cooling one half of the whole number of the transformer sections and then the other half.
