PURPOSE:To improve cooling efficiency by ventilating between an electric apparatus and a cooling equipment provided above the apparatus. CONSTITUTION:A cooling equipment 2, which cools by circulating coolant, is provided above an electric apparatus 1 such as a transformer in which the coolant is enclosed. The coolant is circulated between the electric apparatus 1 and the cooling equipment 2 through oil guiding pipes 3, 4. A ventilation equipment 6 is provided to ventilate the space between the electric apparatus 1 and the cooling equipment 2. With this constitution, the air A, warmed by a top cover 10 of the electric apparatus 1 is blown off by the cooled air C ventilated by the ventilating equipment 6 so that the warmed air does not reach the cooling equipment 2. Therefore, the cooling efficiency of the cooling equipment is improved. |
