摘要(Abstract)：

为了建立特高频局部放电信号典型图谱库,提高变压器局部放电分析判断水平,通过模型测试,建立了针-板电极及板-板电极下的气泡放电和金属物体的悬浮电位放电4种典型特高频局部放电图谱,分析了其频率特性和相位特性,测试、分析了特高频局部放电信号的传播特性。
In order to build the typical signal pattern database of ultrahigh frequency(UHF) partial discharge and improve the analysis and judgment level of partial discharge of transformers,the four typical UHF partial discharge patterns such as foam discharge and suspension potential discharge of metal objects under pin-flat electrode and flat-flat electrode are built by model tests.This paper analyzes the characteristics of the frequency and phase,tests and analyzes the transmission characteristics of UHF partial discharge signal.
