摘要
原葛洲坝500kV开关站构架的安全稳定性不足,存在安装质量缺陷,成为开关站设备安全运行的重大隐患。经过对构架支柱的加固施工,以及将构架横梁由箱形断面梁更换成三角形断面格构梁的改造工程,彻底消除了葛洲坝500kV开关站构架的安全稳定性不足的隐患,为开关站安全运行提供可靠的保证。
The original truss of Gezhou Dam 500 kV switching station has installation quality defects, resulting in instability problem and becoming serious hidden troubles to safe operation. Having strengthened original truss support column and replaced the original box girder with triangular lattice beam for the truss, the hidden troubles of insufficient truss stability are removed, ensuring switch station safe operation.
