PURPOSE:To increase buckling strength of a cover, and to contrive to form a tank for stationary induction electric apparatus in a small type and in light weight by a method wherein longitudinally reinforcing beams are provided in the longitudinal direction on the long side side walls of the apparatus, and base reinforcing beams are provided on the base plate to form a tank, and cover reinforcing beams are fixed on a partially cylindrical shell cover. CONSTITUTION:Longitudinally reinforcing beams 27 are fitted to the long side side walls 28, base reinforcing beams 30 are fixed to a base 29, and a flange 16a is provided. Cover reinforcing beams 25 are fixed to a partially cylindrical shell cover 17, and a flange 17a is provided. The partially cylindrical shell cover 17 is covered on a transformer main body, and clamped to be fixed according to the flanges 16a, 17a. A transformer main body 31 wound with a winding 31b around a core 31a is accommodated inside of the transformer tank thereof. |
