Claims

[Scope of Claim for Utility Model Registration] 1. A stationary induction electric device, an inner tank that stores the same, a sound absorbing layer coated on the outer wall surface and outer surface of the ceiling of the inner tank, and covering the outer periphery of this sound absorbing layer. The sound insulating tank is attached via a support from the inner tank side, and the entire stationary induction electric equipment is made of structural steel and is welded to the bottom of the inner tank, which is on a foundation pedestal fixed to the ground. comprising a weight-bearing bottom base, the bottom base comprising at least a peripheral base portion disposed at the outermost periphery of the bottom of the content tank and formed in a circumferential shape so as to seal the bottom; A low-noise stationary induction electric appliance characterized in that a sound-absorbing layer is adhered to the bottom portion surrounded by the surrounding base portion. 2. The low-noise stationary induction electric appliance according to claim 1, further comprising a cushion layer made of a vibration-proofing material interposed between the bottom base and the foundation frame. 3. In the device according to claim 1, a sound insulating plate is interposed between the bottom base and the foundation frame, and a vibration isolating material is provided between the sound insulating plate and the bottom base and the foundation base, respectively. A low-noise stationary induction electric appliance, characterized in that the sound insulating plate is entirely welded to the lower end of the sound insulating tank so as to seal the entire content tank.
