基于多物理量的GIS绝缘件沿面放电阶段划分策略研究

Gaoya dianqi
气体绝缘金属封闭设备（GIS设备）内部绝缘缺陷导致的局部放电会影响设备的绝缘性能，其中沿面放电是引发GIS设备闪络故障的主要原因。为有效实现局放异常严重程度判定，指导现场GIS局放异常处置，本文提出了基于多物理量的GIS绝缘件沿面放电精细化放电阶段划分策略。首先建立了气体绝缘多物理信号检测试验平台，应用光学传感器、特高频（UHF）传感器和超声波（AE）传感器测量绝缘件不同阶段沿面放电电气量，并与脉冲电流法局放进行数据对照，依照GIS设备绝缘件实际沿面放电可能因素设计沿面放电缺陷模型 ...

超特高压环氧绝缘件超声检测技术及典型缺陷声学回波特征分析

Dianci bileiqi
超特高压环氧绝缘件内部缺陷的可靠检测对于保障电力设备安全可靠运行具有重要意义。文中提出基于超声脉冲反射法实现超高压环氧绝缘件内部气孔、气隙、密度不均等缺陷的有效检出。论文基于声场仿真技术分析多时空尺度下超声波在环氧复合材料内的传播规律，探寻影响环氧复合材料内部缺陷检测灵敏度的关键因素，掌握不同缺陷直径、尺寸、深度下超声回波信号的特征。为验证理论分析有效性，搭建了超声检测试验平台并对特高压盆式绝缘子典型缺陷试样进行了相关的检测试验 ...
