<p>PROBLEM TO BE SOLVED: To provide a low noise stationary induction apparatus which effectively controls a oscillation transmission from tank side panels to an oscillation suppressing steel plate for sound shielding, has a low cost and a simple construction. SOLUTION: This stationary induction apparatus is provided with a main unit and an insulating medium 2 constituted of an iron core, a coil and so on, a tank 3 for containing the main unit 1 and the insulating medium 2, a plurality of reinforced stays 4 provided at a constant interval at the outside of the tank side plates 3a, a frame shape attachment member 6 provided on the reinforced stays 4 and a sound shielding plate 5 constituted of a thin steel plate 5a attached with the attachment member 6, an oscillation suppressing steel plate 5b, and a frame shape weight body 5c. In this case oscillation suppressing paint 7a is applied on the surface of the thin steel plate 5a and oscillation suppressing paint 7a is applied on the surface of a bonding part of the attachment member 6 and the attachment member 6 of the tank 3.</p> |
