溪洛渡电站水轮发电机磁轭热打键工艺研究

摘要

In allusion to the self structural features of hydroelectric generating sets in Xiluodu power station, this paper used the specialized mea-suring tool to carry out reifned calculation for the manipulation preloading, reasonably arranged the manipulation preloading along the distributed and conifgured ladder gaskets of magnet yoke axial and strictly controlled the temperature variation during the processes of heating and cooling. After the sets overspeed test and actual running, this process method guarantees the installation quality of this power station magnet yoke.%针对溪洛渡电站水轮发电机组自身的结构特点，通过使用专用的测量工具，精确计算打键紧量，合理安排打键紧量沿磁轭轴向的分布并配置阶梯垫片，严格控制加热及降温过程中的温度变化，经机组过速试验和实际运行，该工艺方法保证了此电站磁轭的安装质量。
