PURPOSE:To obtain a stationary induction electric apparatus which requires a small space for installation, is easy for assembly and transportation and has a greater soundproof effect by connecting a sound insulation plate and a frame late placed between reinforcement beams with an elastic plate and by fixing the fringe of the frame plate on the reinforcement beams. CONSTITUTION:A sound insulation plate 6 is placed by covering a space kept on the outer surface of the side plate 4A of a tank between reinforcement beams 5 to the height of the beam. The sound insulation plate 6 is supported as follows. Plural studs 7 are fixed near the fringe of the sound insulation plate 6 perpendicular to the plate, plural studs 7 are also fixed near the inner fringe of a frame plate 8 perpendicular to the frame plate 8 which has slightly larger inner dimensions than the outer dimension of the sound insulation plate and larger outer dimension than the inner dimension of the reinforcement beams 5, between both the studs 7 of the sound insulation plate 6 and the frame plate 8 is connected with an elastic plate 9 and the elastic plate 9 and the sound insulation plate 6 and also the elastic plate 9 and the frame plate 8 are fixed on a fixed frame 10 wit nuts 11 through the studs 7. Further, the outer fringe of the frame late 8 is fixed on the reinforcement beams 5, thus supporting the plate 6. |
