摘要： PROBLEM TO BE SOLVED: To provide a stationary induction apparatus capable of suppressing a transient overvoltage while suppressing an increase in outer diameter of stationary induction winding. SOLUTION: The stationary induction apparatus is constituted by supporting with an insulation a conductive shield material 5 which is discontinuous in a peripheral direction of a magnetic iron core between cylindrical winding (3) wound around a periphery of the magnetic iron core 1 and members (2, 4) having a potential difference, and opposing the conductive shield material along the overall length of the cylindrical winding (3). With this configuration, the conductive shield material 5 electrostatically couples with the cylindrical winding (3) to increase the equivalent electrostatic capacity of the cylindrical winding (3) and thereby suppress potential vibration, and potential differences between the conductive shield material 5 and the members (2, 4) having the potential difference are made small to suppress an increase in insulation distance to the cylindrical winding (3).

摘要： PROBLEM TO BE SOLVED: To arrange electromagnetic steel sheets different in magnetic property at optional lamination thickness ratio in order to equalize magnetic flux distribution within an identical wound core, since a magnetic flux distribution within an iron core for stillness apparatus deviates in magnetic flux toward internal periphery side short in magnetic path with respect to all lamination thickness and small in magnetic resitance, and the internal periphery side concentrated by the magnetic flux increases in iron loss due to high magnetic flux density.
SOLUTION: A uniformity of the magnetic flux distribution within a cross section of iron core can be obtained by arranging the electromagnetic steel sheets inferior in magnetic property to that of external periphery side in the internal periphery side short in the magnetic path and small in the magnetic resistance, and the electromagnetic steel sheets superior in the magnetic property to that of internal periphery side in the external periphery side long in the magnetic path and big in the magnetic resistance for equalizing the magnetic flux distribution within the iron core for stillness apparatus.
