摘要

本文应用x射线计算机断层扫描技术对两种交流旋转电机地壁绝缘系统的内部特征进行了研究。从完整的线圈中提取样本,通过虚拟切片和三维绘制程序对其内部结构进行了分析。专门的软件工具被用来发现分布空洞和高密度异常的形态特征。研究发现,树脂的渗透程度、分布微孔的密度和几何形状都与胶带的特性有关。

3D structural analysis of ground-wall insulation of AC rotating machines using X-ray tomography
The X-ray computed tomography has been applied here to inspect the internal features of two types of ground-wall insulation systems of ac rotating machines. Samples extracted from complete coils were scanned and their internal structure was analyzed by means of virtual slicing and 3D rendering procedures. Specialized software tools have been used to discover the morphological features of both the distributed voids and the high-density anomalies. It is was found that the resin penetration as well as the density and the geometries of the distributed microvoids depend from the tape characteristics.
