摘要
模拟了GIS中3种固定金属微粒导致的局部放电。用笔者设计的超高频局部放电检测系统分别对其进行了测量,并提取了局部放电信号高频窄带的谱图特征,建立了3种故障的指纹库。
Three types of partial discharge caused by fixed metal particle in GIS are simulated and detected using a UHF PD detection system designed by the author respectively. Phase resolved PD pattern characteristic of each type are extracted, and the fingerprint database of these three types PD is constructed.
