STATIONARY INDUCTION ELECTRIC APPARATUS

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 【課題】機器を大型化することなく、また防音タンク等の外部の構造物を必要とせずに、簡易な構造で通電騒音を低減する静止誘導電器を提供する。【解決手段】静止誘導電器本体１は、電磁鋼板を積層して形成した鉄心３と、鉄心３に絶縁部材を介して円筒状に巻回された巻線２と、鉄心３および巻線２を収納して絶縁媒体５が充填される密閉容器６と、密閉容器６内で巻線２の外周側に配設されて巻線２を径方向に挟圧する巻線締付リング２３と、巻線２と巻線締付リング２３との間に介在して配設されて巻線２および巻線締付リング２３から押されて圧縮変形可能な弾性部材と、を有する。弾性部材は、絶縁性を有する薄板材を積層した積層構造であって、巻線２と巻線締付リング２３とによって押される方向が積層方向になるように配置されている。【選択図】図１
