摘要: 为研究特高压六相输电线路表面电场和空间电场的特性,参考特高压同塔双回输电线路杆塔结构,计算设计特高压六相输电系统杆塔典型尺寸并选取分裂导线型号。在此基础上,考虑分裂导线中各子导线间的相互影响,计算特高压六相输电导线表面最大场强和线路下距地面1 m处的空间电场分布,并将计算值与相应电压等级的同塔双回线路进行比较,结果表明特高压六相输电导线表面场强和线路下距地面1 m处的空间电场均优于同塔双回线路。故特高压六相输电线路具有更好的环保性能。

Abstract: To study the characteristics of the surface and space electric field for UHV six-phase transmission lines, the typical tower size is designed and the bundle conductor type is selected for the six-phase UHV transmission system by referring to the tower structure of double-circuit transmission lines. The maximum electric field intensity on the six-phase conductor surface and the maximum space electric field intensity at the level 1 m above the ground under the transmission line are calculated with consideration of the interaction between sub-bundle conductors, and the calculated result is compared with that of double-circuit transmission lines of corresponding voltage levels, which shows that both the conductor surface electric field intensity and the space electric field of six-phase transmission lines are better than those of double-circuit transmission lines. It can thus be concluded that the UHV six-phase transmission lines have better environmental performance.

Key words: six-phase transmission, UHV, surface electric field, space electric field, bundle conductor
