干式变压器绕组材质鉴别无损检测研究

Research on Non-destructive Testing of Dry Type Transformer Winding Material Identification

本文中作者研究了铜、铝绕组的透照布置工艺,并对X射线吸收曲线及参数进行了分析,介绍了铜、铝绕组在不同管电压的剂量率衰减规律,建立了基于饱和电压-绕组厚度的铜、铝绕组鉴别方法。

The copper and searched, by the authors analyzed. The attenuation different tube voltages is aluminum winding transillumination layout process is re- n this paper. The X-ray absorption curves and parameters is aw of the dose rate of copper and aluminum windings under ntroduced. The identification method of copper and aluminum windings based on the saturation voltage and winding thickness is established .
