PROBLEM TO BE SOLVED: To provide a stationary induction apparatus capable of reducing noise sufficiently, even in a system where a sound insulating board is attached between upper and lower reinforcement stays.SOLUTION: A stationary induction apparatus includes a tank 1 for housing a stationary induction apparatus body together with an insulation medium 8, upper and lower reinforcement stays 3, 4 provided at at least upper and lower parts of the tank outer surface, respectively, and a sound insulating board 11 arranged between the upper and lower reinforcement stays. The sound insulating board 11 has one end coupled with the upper reinforcement stay 3 via a first coupling metal fitting 12A, and the other end coupled with the lower reinforcement stay 4 via a second coupling metal fitting 12B. The first coupling metal fitting 12A and upper reinforcement stay 3 and the second coupling metal fitting 12B and lower reinforcement stay 4 are entirely bonded, respectively, and the sound insulating board 11 and first coupling metal fitting 12A and second coupling metal fitting 12B are bonded partially.SELECTED DRAWING: Figure 3 |
