PURPOSE:To lower the ceiling of a sound-proof house and to shorten bushing pockets by a method wherein an accommodation tank for tap selector at on-load is arranged by placing the tank below the ground. CONSTITUTION:A recessed section 17 digged down the ground to the setting position of an accommodation tank 4 for tap selector at on-load is provided between the foundation base 6 of the substance 2 of a transformer and that 16 of a sound-proof house 1. The recessed section 17 is provided with dimensions and depth enough for accommodating a part or the whole part of the tank 4. The tank 4 is mounted at the substance 2 under the condition that the tank 4 is accommodated in the recessed section 17. In this way, it is possible to set the upper end of the tank 4 at a lower position by the depth of the recessed section 17. Therefore, short bushing pockets 7 of the house 1 are accepted to improve earthquake proof and the composition of a reinforcement for supporting the pockets 7 can be simplified or omitted. |
