变压器绝缘诊断评估方法对比研究及定量评估方案

Comparative Study on Diagnosis and Evaluation Methods of Transformer Insulation and Quantitative Evaluation Scheme

本文中笔者对比分析了传统理化特征量诊断法和基于介电响应诊断法两种方法的优缺点,并且通过试验研究了水分、老化、温度对油纸绝缘系统频域介电响应特性的影响,得出了相关结论。

The advantages and disadvantages of the traditional physical and chemical characteristic quantity diagnosis method and the dielectric response diagnosis method are compared and analyzed by the authors in this paper.The influence of moisture,aging and temperature on the frequency domain dielectric response characteristics of the oil-paper insulation system is researched.The conclusions are presented.
