恶滩电站增容改造顶盖受力分析

The force analysis of upper cover in Etan Hydropower Station after reformation of capacity expansion

利用恶滩电站老机组原有厂房进行了增容改造。改造机组的上游正常水位抬高后,使过流部件承受压力增大。对改造机组的顶盖进行了受力分析,以确定改造机组是否需要更换新的顶盖。

The old unit of Etan Hydropower Station was reformed for capacity expansion using the original power house. The normal level in upper reaches of reformed unit was raised, and the pressure upon the flow components was increased. The force analysis of upper cover of reformed unit was accomplished, and it is determined by which that whether require to replace a new upper cover for the reformed unit.
