【摘要】 本文以五强溪电厂240MW水轮发电机定子温升分布试验为例,通过带电测温方法,确定定子线棒最高点温升,进而确定水轮发电机最大安全运行能力。该能力的确定,对提高水利资源利用率、机组效率和机组安全运行性都很有意义。更多还原

【Abstract】 An experiment of the temperature rise distribution of the stator for a 240MW hydrogenerator at a site of Wuqiangxi hydropower station was made. A method of measuring temperature with electricity was applied to confirm the highest temperature of stator bar and the biggest capability of safe operation. In this case, it’s important to increase the saving of water resource, the unit efficiency and the unit capability of safe operation.更多还原
