摘要
应用Ｍｉｅ散射理论分析了聚合物电缆绝缘中的缺陷微粒光散射角度特性，发现在８°～２０°，６０°～８０°两个角度窗口黑色杂质，微气孔和混合不好的抗氧剂微粒的散射光强有明显区别，实验结果证实了这一发现。此结论可以被用来作为高压电缆绝缘中缺陷微粒检测时的识别判据。
Mie scattering theory was used to analyze the angular characteristics of defect particles.It has been found that there would be distinct scattering intensity difference among the black partides,microvoids and antioxidant as the defects in polyethylene insulating in 8°～20° and 60°～80°“angular windows” This discovery has been confirmed experimentally.These results can be used to detect and discriminate the type of the defects in high voltage cable insulation.
