X射线测量尺寸校准技术在GIS设备缺陷检测中的应用

Gaoya dianqi
在役GIS设备布置紧凑、结构复杂，现场X射线检测受空间、高度以及检测工装等限制而导致其拍摄角度受限，常出现射线束中心偏移、探测器翻转等非垂直透照情况，其X射线检测图谱出现平移、拉伸等变形，使得GIS部件尺寸的测量误差较大，部分缺陷难以准确定性。文中针对以上典型问题，建立了垂直透照以及X射线束中心偏移、探测器翻转、X射线束中心偏移且探测器翻转等非垂直透照情况下的几何模型，研究了X射线束中心偏移、探测器翻转角度对X射线检测图谱尺寸的影响规律，提出了不同非垂直透照情况下的X射线检测图谱校准公式 ...

干式空心电抗器支柱绝缘子安装节径的设计研究

Gaoya dianqi
为提升干式空心电抗器支撑体系的稳定性，保证支柱绝缘子尽可能多地承受抗压载荷、减少受弯载荷，文中提出了一种基于力矩平衡原理的支柱绝缘子安装节径设计方法。首先将主体线圈沿中轴线进行对半切割，以对半切割后的主体线圈为研究对象，将线圈各包封铺平展开，然后利用力矩平衡原理计算安装节径值。通过比较三维建模软件质心特性与力矩平衡原理计算节径值的差异，分析了气道撑条结构对安装节径值的影响。以某型号特高压干式空心电抗器为例，采用有限元仿真计算方法，分别计算了自重作用与地震作用下支柱绝缘子的弯矩，验证该理论预测方法的有效性。
