Abstract

PURPOSE: To reduce noise by fixing the free end of upper rubber vibration insulator fitted at the upper bend of sound-proof wall on the chain corner of the upper notched portion of vertical stay and on the lower part of tank band and by enclosing the upper space between the outer wall and the sound-proof wall of tank.
CONSTITUTION: The upper end of the reinforcing vertical stay 4 of the tank 1 is provided with the upper notched portion 15 to from the acute portion 16 between the lower part of the tank band and the upper notched portion. The upper bend 17 of the sound-froof wall 7 is given the snap 14 and then the one end of the upper rubber vibration insulator 8 is fastened to the whole periphery of the sound-proof wall, while the free end of the rubber vibration insulator is fastened to the acute portion in close proximity to the lower part of tank to enclose the upper space between the outer wall and the sound-proof wall of the tank. Thus, the noise which is transmitted from the side of tank to the upper part is interruped, thus reducing the noise of the whole transformer
