摘　　要：针对某水电站机组技术供水系统蜗壳取水口拦污栅历次堵塞而换型的原因分析,通过设计与试验,历时三个检修周期,最终探索了一种改型立体板式结构拦污栅,能够有效减轻拦污栅严重堵塞情况的发生,提高了电站技术供水系统运行的安全可靠性。The trash rack at the spiral case intake of the technical water supply system in a hydropower station had to be replaced due to frequent clogging.With careful design and tests,an innovated three-dimensional plate structure trash rack is developed,which can effectively reduce the serious clogging cases of the trash rack and improve the safety and reliability of the technical water supply system of power stations.
