摘　　要：本文中作者研究了特高压交流变压器低电位高场强区域绝缘缺陷试验检测技术,搭建变压器低电位高场强区域模拟放电试验平台,通过模拟不同缺陷下的放电,提出了绝缘缺陷判断方法。The test and detection technology of insulation defects in the low potential and high field strength areas of UHV AC transformers is researched by the authors in this paper. The simulated discharge test platform in the low potential and high field strength areas of the transformer is builted. The insulation defect judgment methods by simulating the discharge under different defects are proposed.
