Embodiment Construction
[0043] figure 1Shown is a forced circulation evaporative cooling device for the stator winding of a vertical hydroelectric generator. For the sake of brevity, a wire bar group in which three stator wire bars are connected in series is taken as an example for schematic illustration. The three stator bars are connected end-to-end through the parallel head cover 2 to form a serial stator bar group 1 . The upper end of the stator bar group 1 is connected with the upper insulating lead pipe 4 through the electro-hydraulic separation joint 3 . The electro-hydraulic separation joint is a fixed part that seals the insulating lead pipe and the stator bar. The upper insulating lead pipe 4 is connected with the gas collecting pipe 6 through the sealing joint 5 . The air collecting pipe 6 is connected with the cooling space of the condenser 7 again. The cooling space of the condenser 7 is connected with the liquid return pipe 8 . The liquid return pipe 8 is connected with the magneti...
