Dianci bileiqi盆式绝缘子是GIS断路器中的关键部件，其生产与运输过程中产生的气泡、裂纹、表面脏污等缺陷，将引起GIS发生沿面闪络等故障，降低设备运行可靠性。本文利用超声导波方法对GIS盆式绝缘子进行缺陷检测，首先在Comsol中构建了盆式绝缘子三维仿真模型，设置超声波激励点与接收点分别对完好绝缘子与有缺陷绝缘子进行超声导波仿真研究，有缺陷时接受信号幅值小于完好绝缘子，验证了超声导波方法的有效性。后针对仿真信号分别添加5dB高斯白噪声，并使用小波降噪，VMD降噪和OMP降噪方法对含噪声信号分别进行处理 ...

Gaoya dianqi绝缘子沿面绝缘是直流GIS/GIL绝缘系统的薄弱环节，由于常规交流绝缘子设计准则不再适用于直流工况，研制新型直流GIS/GIL盆式绝缘子对提升直流管道装备可靠性具有重要意义。该研究将直流GIS/GIL中金属微粒的危险运动行为影响纳入管道电极表面场强控制范畴，明确绝缘子初始状态与直流叠加雷电冲击复合电压下沿面场强控制标准，并建立表面电荷积聚与复合电压耦合作用下绝缘子沿面场强考核模型。进一步提出基于表面轮廓曲线优化的直流盆式绝缘子设计方法，依托Bernstein方程开展绝缘子表面轮廓曲线重构 ...
