PROBLEM TO BE SOLVED: To reduce eddy current loss due to leakage flux from a winding, while reducing the total weight of a magnetic shield provided in the tank of a stationary induction electric unit.SOLUTION: A stationary induction electric unit is constituted of a core 1 having a core leg 1A and a core yoke 1B, windings 2, 3 4, 5 wound around the core leg 1A, a tank 10 having the core 1 and the windings 2, 3 4, 5 internally, and a first magnetic shield 28 and a second magnetic shield 38 formed by laminating silicon steel plates on the inside of the tank 10. The first magnetic shield 28 is arranged oppositely to the windings 2, 3 4, 5, the second magnetic shield 38 is arranged between the first magnetic shield 28 and the tank 10, and the first magnetic shield 28 and second magnetic shield 38 are fixed to the tank 10 by means of separate support members, respectively.SELECTED DRAWING: Figure 1 |
