摘　　要：为适应电力设备状态检修的发展趋势,克服传统评价模型在数据获取方式、部件划分、性能指标设置、评分模型等方面的缺陷和不足,依据国家电网公司变压器状态评价框架,结合停电试验、带电检测、在线监测、专业巡检、运行环境等因素,重新梳理了设备状态量、不良工况和家族缺陷等因素,构建了一套综合多源信息的全量状态评价模型。实例分析证明该评价模型更全面、即时地描述了电力变压器的实际运行状态,可为一线运维人员制定设备检修策略提供科学指导,也为其他变电设备的状态评价提供了实践依据。In order to adapt to the development trend of the power equipment condition based maintenance and overcome the disadvantages and deficiencies of traditional condition evaluation model in data acquisition approaches,component classifications,performance indicators and assessment model,a comprehensive condition evaluation model based on multi-source information is proposed in this paper according to the transformer condition evaluation framework of State Grid Corporation.Combined with the offline test,live detection,on-line monitoring,professional inspection and operating environment,equipment criteria,undesirable service condition and family defects are re-classified in this model.Practice example verifies that the proposed evaluation model can describe the power transformer＇s operating state more comprehensively and immediately.The evaluation results can provide scientific guidance for front-line operation and maintenance staff to develop equipment maintenance strategy,and also can provide practical basis for the condition evaluation of other power transformer equipment.
