<p>PURPOSE: To obtain a soundproof device for a stationary induction apparatus, such as the transformer, which can be moved together with a tank and can be reduced in area of installation. CONSTITUTION: Rear plates 14 are fitted to an outer sound-insulating plate 13 with clearances in between and the end section of the plate 13 is bent at right angle. The bent part of the plate 13 is supported by a tank reinforcing member 11a by putting the bent part on the member 11a with a vibration-proof member 12a in between and the plate 13 is fitted to tank reinforcing members 11a and 11b through a vibration-proof members 12b. Therefore, the sound- insulating characteristic of a stationary induction apparatus can be improved by the sound-insulating plate 13 constituted in the double-wall structure and the area of installation of the apparatus can be improved as compared with a stationary induction apparatus using a separately placed sound insulating plate by directly fitting the plate 13 to the tank.</p> |
