Gaoya dianqiGIS盆式绝缘子表面污秽和裂纹等缺陷会使得其表面的闪络电压降低，严重危害电力网络的正常运行，因此盆式绝缘子状况检测研究对于保障电网安全运行具有重要意义。基于模态分析法，文中研制了盆式绝缘子状态带电检测系统，对盆式绝缘子表面污秽、裂纹缺陷开展试验研究。结果表明盆式绝缘子污秽缺陷会使得其模态传递函数幅值发生变化，且盆式绝缘子模态特性对于污秽质量的变化敏感；裂纹缺陷会使得盆式绝缘子模态传递函数极值点发生后移；表面污秽与表面裂纹缺陷共同作用下，模态传递函数的高频段2 000~4 000 Hz内幅值变化更剧烈 ...

Gaoya dianqi根据变电站瓷支柱绝缘子带电检测缺陷的实际需求，以220 kV瓷支柱绝缘子为研究对象，深入研究了裂纹长度、裂纹形状和激振位置对瓷支柱绝缘子振动检测的影响。首先阐述了瓷支柱绝缘子内部缺陷振动检测的基本原理，然后建立瓷支柱绝缘子有限元数值分析模型，利用脉冲信号模拟锤击进行瞬态分析，并搭建实验平台进行测试分析。仿真和实验结果表明：裂纹长度越大，在功率谱图上表现为正常频率区间内的峰值降低，故障区间内的峰值所对应固有频率左移，激振点远离裂纹侧时波峰的加速度响应谱值出现小幅度的减小 ...
