摘要

设计制作了5种油纸绝缘结构模型用以模拟变压器中的典型缺陷。利用数字式局放测量系统获取了大量放电谱图和放电脉冲波形。分析了不同缺陷类型的局部放电特性

为进一步研究电力变压器局部放电模式识别和绝缘老化特征提供了科学依据。

Abstract

According to the analysis of defects in oil-paper insulation of power transformer

five corresponding PD models are designed. Using the digital PD measuring system

plenty of related patterns of discharges and discharge oscillograms are obtained. By means of analyzing the characteristics of different kinds of defects

all these will be helpful for further research on PD pattern recognition and insulation aging of power transformers.
