PROBLEM TO BE SOLVED: To achieve improvement of cooling performance while maintaining a reduction in size and weight in sealed type power generation and transformation facilities.SOLUTION: A gas circulation space 14 through which a cooling gas g flows is formed among outer surfaces of an inner shell container 6 and inner wall surfaces of a sealed container 1 by incorporating the inner shell container 6 into the sealed container 1. A partition wall 7 for dividing an inner space of the inner shell container 6 into two sections in a front-back direction toward an axial direction of the inner shell container 6 is installed inside the inner shell container 6. It is arranged that one space out of the inner space of the inner shell container 6 divided into the two sections by the partition wall 7 is a generator chamber 12, and the other space is a power transformer chamber 13 in which a power transformer 4 and a conversion device 5 are disposed. A communication hole 15 is opened at a central portion of the partition wall 7, and the generator chamber 12 and the power transformer chamber 13 are caused to communicate with each other. A fan 10 of a generator 3 is disposed adjacent to the communication hole 15, and the cooling gas g is caused to flow from the power transformer chamber 13 to the generator chamber 12 via the communication hole 15 by the fan 10. |
