500 kV变电站主变例行检修标准化作业流程

Standardized Work Flow of Routine Maintenance for 500 kV Substation Transformers

以500 kV汾湖变1号主变例行检修为例,从主变检修周期、作业风险和停电前、停电期间、复电后各阶段详细介绍500 kV变电站主变例行检修标准化作业流程,以期为作业安全、质量、进度的管控水平的提升提供参考。

This paper takes the No.1 transformer of 500 kV Fenhu substation as an exemplary case and elaborates in detail standardized work flow of routine maintenance for 500 kV substation transformers from the perspectives such as MT maintenance cycle,operational risks,and the work stages of pre-outage,intra-outage and post-outage.It may provide useful information for the promotion of management and control of work safety,quality and progression with respect to routine maintenance of main transformers with 500 kV and other voltage levels.
