PURPOSE:To suppress the resonance of a conservator of a electric induction apparatus with earth quake by a method wherein plural equipping bases are provided on the side plate of tank at the upper and lower parts and at the horizontal directional parts and plural supporting frame bodies to support the conservator are provided, and the supporting frame bodies are connected with each other through connecting beams. CONSTITUTION:The plural equipping bases 9 are provided on the side plate of tank at the upper and lower parts and at the horizontal directional parts, and a supporting frame body 16 is formed together with supporting legs 4, 8 being the upper ends thereof connected with an equipping frame 7 and the lower ends thereof fixed to a connecting frame 15 being fixed to the equipping bases 9. The supporting frame bodies 16, 16 equipped at the upper and lower directions in parallel facing with each other are connected with connecting beams 11, 12 at the parts between the connecting frames 15, 15 at the upper and lower positions to form a frame type. Weight of the conservator connected to a tank is supported by the plural supporting frame bodies. Accordingly because the supporting leg parts are formed in the frame type being integrated in one body by the connecting beams, natural frequency can be heightened, and resonance with earthquake can be suppressed. |
