摘　　要：根据电厂对机组检修的周期要求,结合某水电站B转轮室过流部件表面型线的特殊性及缺陷特点,形成了该转轮室消缺方案。方案借助模块化思路,提出了"补偿块"修复缺陷的消缺方式,将缺陷区域分解成多个模块,通过更换指定模块的方法达到消缺目的,并研究了该模块化消缺技术在转轮室球面整体更换工艺上的应用。According to the requirements of repair cycle, and combined with the particularity and defect features of hydroelectric power plant B, the defect elimination scheme for the runner chamber is formulated. Based on the thought of modularization, the compensation block is proposed to eliminate the defects, which divides the runner chamber into multiple modules and replaces those defective modules with the compensation block. And, the application of the proposed modular defect elimination technology to the overall replacement process of runner chamber is studied.
