<p>PROBLEM TO BE SOLVED: To reduce vibration containing wideband frequency components transmitted to a closed container via a magnetic shield, in a stationary induction electric device.SOLUTION: A stationary induction electric device includes a stationary induction electric device body 11, a closed container 1 for housing the stationary induction electric device body 11 and incorporating an insulation medium 5, a magnetic shield 9 supported on the inner wall of the closed container 1 and performing magnetic shielding from the stationary induction electric device body 11, and a stay 10 arranged between the closed container 1 and magnetic shield 9 and formed by laminating a plurality of planar base materials having different rigidity and attenuation factor. Preferably, the plurality of base materials include a steel sheet base material and an insulating base material, where the steel sheet base material is arranged at a position in contact with the closed container 1.</p> |
