摘　　要：基于活化能这一理化特征参量,从微观角度定量研究变压器的缺陷检测与老化评估技术,建立了泄漏电流、活化能与老化时间的定量关系模型,研制出基于活化能特征指数的变压器绝缘系统状态评估装置。实例分析表明,本方法具有较高的适用性。Based on the activation energy,this paper studied the defect detection and aging evaluation technology of transformers from a microscopic perspective firstly.Then,a quantitative relationship model was established among leakage current,activation energy and aging time.Finally,the transformer insulation system condition evaluation device was developed based on the activation energy characteristic exponent.The diagnosis proved the correctness and validity of the method.
