| 摘 要： | 覆冰四分裂导线的空气动力特性,由于覆冰子导线尾流的相互干扰可能不同于覆冰单导线。针对两种不同冰型制作覆冰四分裂导线模型,通过风洞试验测试获得不同冰厚和不同风速下覆冰四分裂导线静态空气动力系数随攻角的变化曲线。结果表明,在一定的攻角下,子导线尾流相互干扰对空气动力系数有明显影响。所得试验结果为覆冰四分裂导线的舞动及其防止技术的研究提供必要的数据。 |

| Abstract: | The aerodynamic characteristics of iced quad bundled conductor may be different from those of iced single conductor because of the wake interference around the sub-conductors of the bundled conductor.Test models of iced quad bundled conductors with two different cross section shapes of ice were prepared.The static aerodynamic coefficients of the models varying with attack angle,in the cases of different ice thickness and wind velocities,are obtained by wind tunnel test.It is observed that the wake interfere... |
