一起500 kV线路多支复合绝缘子芯棒酥朽发热特征及缺陷起始原因分析

Dianci bileiqi
针对一起500 kV同塔双回线路多支复合绝缘子发热事件，开展了现场不同角度的无人机红外测试，对酥朽缺陷绝缘子的温差、发热区段数量及长度进行了分析，并对更换后的发热绝缘子开展外观检查、红外复测、剖检及工业CT、带护套水扩散试验，对比了实验室与现场红外测试差异，通过剖检对比了芯棒酥朽区段与发热位置的关系，并对酥朽原因进行了讨论。结果表明，现场38支酥朽复合绝缘子，94%的绝缘子为1处或2处芯棒发热、6%出现3处发热，79%的绝缘子发热区段长度最长为1至2个伞裙单元、21%存在3-5个伞裙单元的连续发热 ...

基于联合老化试验的GIS隔离开关绝缘子气隙缺陷劣化过程研究

Gaoya dianqi
气体绝缘金属封闭开关设备（GIS）绝缘件内部缺陷引起的放电击穿故障会造成设备非计划停运，且GIS设备故障检修周期长、影响范围大，严重威胁设备和电网的运行安全。目前，对于GIS设备绝缘件应力集中、弱电场区域微小气隙等部分潜伏缺陷，现有试验方法检测有效性受限，其长期运行中的缺陷劣化规律尚不清晰，制约了GIS绝缘件质量提升。文中基于一起GIS隔离开关绝缘子局放缺陷，提出了GIS设备绝缘件的温度、机械—电场同步老化、强电场老化试验方法，探索内部缺陷发展规律。首先将绝缘子装入GIS隔离开关样机 ...

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 ...
