工业CT在电磁线圈缺陷检测中的应用

Application of Industrial Computerized Tomography in Testing of Fault Magnetic Coil

通过工业CT(ICT)对电磁线圈进行内部结构分析,可以避免电磁线圈解剖的困难。ICT能有效地检测出电磁线圈中的漆包线断开、零部件安装不到位、漆包线熔断、绕组变形、包封层中气孔、多余杂线以及金属杂质等缺陷,并且能够精确地确定出缺陷的位置和几何形状。工业CT分析对提高电磁线圈产品的质量,改进生产工艺有指导意义。

The internal structure analysis of the magnetic coil was using industrial CT to avoid the difficulty of disassemble magnetic coil during failure analysis.The computed tomography(CT)imaging characteristics for internal defects of resin matrix composite products were studied and analyzed.The results show that industrial CT is able to effectively detect various defects of the fault magnetic coil such defects as breakage of enameled wire,inadequate installation of components,fusing of enameled wire,winding deformation,porosity in the envelope,excess wire or metal impurities,et al.industrial CT can accurately determine t the location and geometry of the defects.The analysis of Industrial CT application has guidance significance for improving the quality of magnetic coil and production technology.
