摘要
结合仙居抽水蓄能电站500kV电气主接线变更设计,地面GIS新增单元施工,从施工安全、成品保护、SF6气体回收、GIS组装、抽真空处理、SF6气体充注及现场交流耐压试验等方面阐述了主要施工要点控制,为GIS组合电器改造工程施工提供可借鉴的经验。
Combining improved design of 500kV main electrical connection for Xianju pumped storage power with added unit GIS construction on the ground,this paper expounds the key construction points control from various aspects including construction safety,finished product protection,SF6 gas recycling,GIS assembly,vacuum treatment,SF6 gas filling and site alternsting current withstand voltage test etc.Through the relevant analysis,it further provides referential experience for following GIS electrical engineering reconstruction.
