在现有三相输电线路的基础上,把紧凑型线路的设计思路与四相输电原理相结合,详细分析和讨论了四相输电架空线的结构设计与选择。在全面考虑了导线排列、导线间距、相导线的分裂数量和分裂间距等参数,并计及以上各项参数组合方案的基础上,详细计算和比较了四相输电架空线的自然功率和电磁场环境指标,为四相输电架空线路的设计和选型积累了大量的数据和材料,提供一种实用的分析方法,并为下一步对四相输电系统可行性的全面研究打下基础。

Based on the foundation of existing three-phase power transmission lines, this article unifies the design method of compact power transmission lines and the four-phase power transmission theory; comprehensively analyses and discusses the structural design and choice of four-phase power transmission lines. In having comprehensively considered the lines arrangement, the phase distance ,the number of phase separation and so on the distances between each sub-lines ,it calculates and compares the nature transmission power and the electromagenetic radiation level of the four-phase power transmission lines,which accumulates massive data and abundant material and provides a practical method for the design of four-phase power transmission lines. This is the foundation to the feasible research of four-phase power transmission system.
