Hydro-generator stator bar evaporative cooling system with auxiliary liquid return pipe

The invention discloses a hydro-generator stator bar evaporative cooling system with an auxiliary liquid return pipe. The system is composed of a condenser, a pressure monitoring element, a steam collecting pipe, an evaporative cooling medium, a bar with a hollow flow channel, a bar temperature measuring element, a liquid collecting pipe, a main liquid return pipe, the auxiliary liquid return pipe, a liquid charging and discharging system, a liquid connector, an insulating liquid guide pipe, a steam outlet pipe and a liquid level meter. According to the invention, the flow resistance in the evaporative cooling system is reduced, the cooling flow in the system is correspondingly improved, and meanwhile, the heat exchange efficiency of the condenser in the system is also improved. 本发明公开一种带有辅回液管的水轮发电机定子线棒蒸发冷却系统，由冷凝器、压力监测元件、集汽管、蒸发冷却介质、带有空心流道的线棒、线棒测温元件、集液管、主回液管、辅回液管、充排液系统、液接头、绝缘引液管、出汽管及液位计组成。本发明既降低了蒸发冷却系统中的流动阻力，相应地提高系统中的冷却流量，同时也提高了系统中冷凝器的换热效率。
