摘　　要：变压器的故障类型具有多样化的特点,为了建立可靠、准确的变压器运行状态评价方法,研究过程设置了涵盖绝缘受潮、局部放电、电弧放电等在内的三级评价指标,将运行状态划分为正常、注意、异常、严重四个等级,运用变权灰云模型计算指标和评价等级之间的关联度,最后对指标评分和权重的乘积进行求和,得出综合评分。经过实例分析,此次设计的评价模型优于同类算法模型。The fault types of transformers are diversified,in order to establish a reliable and accurate evaluation method of transformer operation status,the research process sets up three-level evaluation indexes covering insulation moisture,partial discharge,arc discharge,etc.,and divides the operation status into four grades of normal,attention,abnormality,and severity,and calculates the correlation degree between the indexes and the evaluation grades by applying the variable-weighted gray cloud model,and finally sums up the product of indexes'scores and weights to get the comprehensive scores.Finally,the product of rating and weight is summed up to get the comprehensive rating.After example analysis,the evaluation model designed this time is better than similar algorithm models.
