摘　　要：随着社会经济的持续快速发展,电网建设需加快步伐以满足电力需求的不断增长。为合理利用走廊资源,实施对不同负荷目标的电力输送,将一回±800 kV直流线路和一回±500 kV直流线路共塔架设是一个合理可行的解决方案。参考相关规程规范,以计算数据为基础,结合已有±500 kV、±800 kV等工程的设计运行经验及成果,推荐合理的导线对地及交叉距离、线路走廊宽度,为后续特高压与超高压直流同走廊输电规划提供技术依据。With the fast development of social economy,it has to accelerate the power grid construction to meet the rising demand for electric power.To make better use of the transmission corridors to delivery various amount of electrical power,the integration of ±500kV DC transmission lines and ±800 kV DC transmission lines into a same tower is a feasible solution.The paper gives the recommended values of ground clearance,crossing clearance of conductors and the width of transmission corridors of the proposed project based on not only the calculation data and relevant standers but also the design of exiting ±500 kV and ±800 kV transmission projects.Future designs of UHV DC transmission lines may receive guidance and instructions from the calculation results and conclusions of this paper.
