<P>PROBLEM TO BE SOLVED: To provide a stationary induction electric appliance which has a high vibration insulating performance and a noise reduction performance by reduced man-hours. <P>SOLUTION: A stationary induction electric appliance includes: tank reinforcing members 4 which form protruding ridges laterally arranged in a manner where each ridge is oriented in the vertical direction by being fixed on external side surfaces 3 of a tank housing a stationary induction electric appliance body 1; tank reinforcing ribs 7 joining the tank reinforcing members 4 to each other; and sound insulating panels 5 welded to cover spaces formed by the tank reinforcing members 4 and the tank reinforcing ribs 7. The sound insulating panel 5 includes: two or more sound insulating plates 5a and 5b opposed to each other; and frame-like reinforcing ribs 5c which are arranged so as to form a closed space 9 between the sound insulating plates and whose adjacent sides are attached to each other in a manner tilted from the right angle such that the opposite sides are not parallel. <P>COPYRIGHT: (C)2012,JPO&INPIT |
