PURPOSE:To minimize decrease of concentration ability of the collected apparatus during breakage of an airtight container by separating it into a plurality of air sealed cabins by airtight bridge walls and connecting with short pipes between the rotary electric machines. CONSTITUTION:Rotary electric machines 1 and connecting pipes 2 and 3 which provide an airtight flow passage between the machines 1 are housed within an airtight container 4. The machines 1 are respectively attached to the bottom of the container 4, and the connecting pipes 2 and 3 are connected to a hole passing through the cabin with airtight manner by giving flexibility to part of them. The pipe 3 connecting between the machines 1 and the pipe 2 constitute relatively flexible pipes. The machines 1 which belong to a different condensing stage are housed in the respective air sealed cabin separated by a air tight bridge wall 6 within the container 4, and each of the rotary electric apparatus group is connected in cascaded piping. |
