摘　　要：葛洲坝水力发电厂开关站 ,5 0 0kV构架的改造工程系华中电网的重大技术改造项目 ,历时 5年 ,在不影响开关站安全运行的情况下 ,克服设计和施工现场的重重困扰 ,最终完成了构架柱加固、端撑及构架梁的改造 ,消除了构架结构的重大安全隐患 。The retrofitting project of 500 kV frames at the switch station of Gezhou Dam Hydraulic Power Plant is an important technical retrofitting project of the middle China Power Network, which has lasted for 5 years. The retrofitting project was implemented, including reinforcement of structural columns, end supporting and structural beams in conditions without effect on safe operation of switch station and overcoming difficulties in design and construction site. As a result, the significant safe hidden troubles in the carcass structure have been eliminated to ensure the safe and stable operation of the switch station.
