摘　　要：随着带电检测大规模的应用,海量检测及运维检修数据未得到充分利用,不能指导和优化运维周期。提出基于检测数据的设备状态评价和全站状态评价方法,形成基于历史数据和风险度指标的设备和全站风险排序,依据变电站的运行状况和缺陷危急程度制定不同的策略,辅助现场运维。通过对实际检测数据的统计分析,结果表明提升了设备运维效率和质量。Presently,many substations use live detection.This testing method can get massive data of detection,operation,and maintenance.However,the development of these data is not sufficient.Because of this problem,the data could not guide and optimize the operation and maintenance cycle.This paper proposed equipment status evaluation and site-wide status evaluation methods based on inspection data to form the equipment and site-wide risk ranking based on historical data and risk indicators.It could assist in on-site operation and maintenance and make strategies for the substation under different circumstances.By analyzing the practical test data,this strategy improves the efficiency and quality of the operation and maintenance of the equipment.
