西华大学硕士学位论文格式规范 变压器绝缘的构成及其构成元件特性分析 15  PAGE I 摘 要 变压器的严重事故不但会导致自身的损坏，还会中断电力供应，造成巨大的 经济损失。由内绝缘老化而引发的变压器故障占变压器事故的重要部分。以介电 响应为基础的极化去极化电流法和频域介电谱法不仅是无损的电气诊断技术，而 且是变压器绝缘状态诊断中本领域国内外学者研究的热点之一。研究一种对变压 器绝缘老化进行无损诊断的介电响应测量新方法或新特征量是尚需解决的难题之 一。变压器油纸绝缘的介电性能和空间电荷特性的联系、油纸绝缘介质在老化过 程中绝缘油性能对空间电荷形成及迁移的影响、以及作为油纸绝缘老化产物且直 接影响油纸绝缘介电性能的水分对多层油纸绝缘介质空间电荷的影响，均是需要 研究解决的问题。 关键词：变压器；高压绝缘；绝缘材料 高压电绝缘课程论文 PAGE \* MERGEFORMAT17 Abstract The serious accidents of transforme can ot only cause their own damage, but also interrupt the power supply, causing huge economic losses. Transformer failures caused by internal insulation aging is an important part of the transformer accident.The polarization/depolarization current method and requency domain dielectric spectroscopy based on dielectric response are not only non-destructive electrical diagnostic technique, and also the research focus of domestic and foreign scholars in the field of transformer insulating condition assessment. Investigating new method or new characteristics parameters for diagnosing the transformer insulation aging and assessing its life non-destructively using dielectric response technique is difficult question to be rsolved.
