摘要

检测变压器绝缘纸聚合度是判断其固体绝缘老化程度最直接有效的方法

实验室制取了53个不同聚合度的变压器绝缘纸样

采用国标法（粘度法）检测其聚合度。通过漫反射光谱仪对所有纸样进行扫描

结合偏最小二乘回归法建立了绝缘纸聚合度与光谱参数间的定量模型

模型相关系数为0.951 9

预测均方根误差RMSEP为67.5。该方法检测绝缘纸聚合度的精密度和准确度基本满足工程应用要求

为变压器固体绝缘状态提供了一种快捷、无损的检测方式。

Abstract

It is an effective way to judge the aging degree of power transformer insulation paper by detecting the polymerization degree（DP）. 53 samples are made and their DPs are determined by standard method（viscometric method）. A quantitative model is established by using diffuse reflectance spectroscopy and partial least squares（PLS）

with the correlation coefficient of 0.951 9 and RMSEP of 67.5. Precision and accuracy of spectroscopy method can basically meet the requirement of engineering application. This paper provides a rapid and nondestructive way for judging the aging degree of power transformer.
