Research on Varying Duty Operation of Self-Circulation Evaporative Cooling System of Single Stator Collector Ring in Hydro-Generator

Abstract:

With the advantage of high-security, energy-saving and high efficiency, the self-circulation evaporative cooling technology provides an ideal solution for the cooling problem of stator collector ring in hydro-generator. In this paper, the operation characteristics of self-circulation evaporative cooling system of single stator collector ring under different work conditions were analyzed by experiments. The experimental results show that the cooling performance of this new cooling system is satisfactory. The temperature distribution of stator collector ring and system pressure distribution were discussed on the basis of experimental data and those variation tendencies were concluded. The research results in this paper provide the basis for further researches and practical application of this new cooling system.
