PURPOSE:To prevent the decrease of electric field intensity without making work process complicated, by alternatively arranging the connecting parts of the liquid accumulators of each cooling duct installed in parallel to the built direction of winding and the insulating pipes as the neighboring liquid accumulators are connected to each insulating pipe at their opposite ends. CONSTITUTION:The liquid accumulators 31a-31c arranged in the built direction of winding 33 are connected to the insulating pipes 12 as the neighboring accumulators have inverse direction with each other. The cap nut 23 at the top of liquid accumulator and the hollow bolt 24 at the top of insulating pipe 12 are tightened and fixed with each other. The connection part of them is covered by a dome-shaped shield material 34. As the connecting parts of the liquid collectors 31a-31c and the insulating pipes 12 are inverse with each other with respect of the neighboring liquid accumulator, the distance for insulation between then can be sufficiently obtained, and dielectric strength is increased. As it is unnecessary to manufacture the bolt and nut into round shape, the extra work process can be dispensed with. |
