PROBLEM TO BE SOLVED: To provide a stationary induction electric apparatus reducing communication noise with a simple structure, without up-sizing the apparatus and without requiring any external structure such as a sound-proof tank.SOLUTION: A stationary induction electric apparatus body 1 has: an iron core 3 formed by laminating magnetic steel sheets; a winding 2 wound cylindrically around the iron core 3 via an insulating member; a closed container 6 filled with an insulating medium 5 while housing the iron core 3 and the winding 2; a winding fastening ring 23 disposed on the outer peripheral side of the winding 2 in the closed container 6, and nipping the winding 2 in the radial direction; and an elastic member interposed between the winding 2 and the winding fastening ring 23, and capable of compressive deformation by being pushed by the winding 2 and the winding fastening ring 23. The elastic member is a lamination structure of an insulating sheet-material, and arranged so that the pushing direction of the winding 2 and the winding fastening ring 23 becomes the lamination direction.SELECTED DRAWING: Figure 1 |
