Abstract

Transmission safety and capacity of overhead transmission lines are important for the electric power system. Icing seriously threatens the security of power delivery, reflected in the line galloping and line-tower collapsing. Here, novel anti-icing aluminum (AI) conductors with different diameters were successfully prepared by anodization techniques. The superhydrophobicity and glaze icing behavior of all specimens were verified. Furthermore, the transmission capacity of prepared Al conductors was evaluated by up- current experiments. Line loss of all Al conductors was calculated and determined by mathematical formulations. Results show that anodized Al conductors exhibit good anti-icing properties and increased transmission capacity, attributed to the superhydrophobicity and heat dissipation of the nanopores micro-structure. The good anti-icing properties and large transmission capacity make the anodized overhead transmission line the potential low-cost candidate to improve transmission safety and capacity.

提高输电能力的新型防冰铝导体的制备与实验研究

架空输电线路的传输安全和容量对电力系统至关重要。结冰严重威胁着电力输送的安全，主要表现在线路飞奔和线塔倒塌。本文采用阳极氧化技术成功制备了不同直径的新型防冰铝导体。验证了各试样的超疏水性和釉覆行为。此外，通过上电流实验对制备的铝导体的传输能力进行了评价。用数学公式计算并确定了所有铝导体的线损。结果表明，阳极氧化铝导体具有良好的防冰性能和更高的传输能力，这主要归功于纳米孔微结构的超疏水性和散热性。阳极氧化架空输电线路具有良好的防冰性能和较大的输电容量，是提高输电安全性和输电容量的潜在低成本候选线路。
