摘要

从经济性与环保特性2个方面研究了特高压六相输电线路与同杆双回线路相比所具有的优势。通过对杆塔间距的计算，量化验证了六相输电技术可减少线路投资和土地占用面积。计算了六相输电线路的自然传输功率，指出六相输电线路在减少投资的同时提高了自然传输功率，因此具有更好的经济性。在环保特性方面，由导体表面电位梯度入手，论述了六相输电线路比同杆双回线路具有更低的可闻噪声和无线电干扰场强的原因。

Abstract

By a study of the six-phase transmission line advantages in construction cost and environmental characteristics in comparison with the double-circuit transmission line，the reduction in the construction cost and space of the transmission corridors are quantitatively validated through the calculation of the space between towers.The natural power transfer capacity of six-phase transmission line is calculated.It is proved that six-phase transmission line is more economical as it can increase the natural power transfer capacity while reducing the installation costs.With respect to environmental characteristics，an account is given of the lower audible noise and radio interference field in six-phase transmission lines than in the double-circuit transmission lines by proceeding from an analysis of the maximum electrical gradient of the conductor surface.
