<P>PROBLEM TO BE SOLVED: To solve problems of the countermeasure cost and the workability of a conventional countermeasure where a magnetic shield is fixed to a tank surface by screws for leakage magnetic flux which flows into a tank resulting in the increase of the losses of devices and the occurence of localized heat and affects peripheral devices in a static apparatus such as an oil-filled power transformer and a reactor. <P>SOLUTION: A static apparatus houses an iron core, a coil, and an insulation oil which insulates and cools the iron core and the coil in a tank. In the static apparatus, a wave rib is formed at an outer periphery of the tank in the vertical direction, and stays are attached to an inner wall of the tank in the vertical direction at predetermined intervals. Each stay has a C shape into which a magnetic shield is inserted, and the magnetic shield is inserted into the C shape and fixed thereto. <P>COPYRIGHT: (C)2013,JPO&INPIT |
