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.
Abstract
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 de-vice was developed based on the activation energy characteristic exponent.The diagnosis proved the correctness and validity of the method.
