气体复合绝缘缺陷局部放电特征研究
|
摘要
以典型固体-气体复合绝缘缺陷为参考,设计自由金属颗粒、悬浮金属块、尖端、沿面污染4种典型绝缘缺陷模型。采用2种不同电压下雷电冲击电压、振荡雷电冲击电压、操作冲击电压、振荡操作冲击电压对设计模型进行试验和分析,采集试验数据,分析放电特征,为相关检测评价提供依据。
Based on typical solid-gas composite insulation defects, four typical insulation defect models are designed which are free metal particles, suspended metal blocks, tip and surface contamination.Lightning impulse voltage, oscillating lightning impulse voltage, switching impulse voltage and oscillating switching impulse voltage under two different voltages are used to test and analyze the design model.The test data are collected to analyze the discharge characteristics which provides a basis for relevant detection and evaluation.
