中文摘要: 合理设计直流线路的极间距对控制直流线路工程电磁环境和降低工程建设费用意义重大.针对无线电干扰、可听噪声、离子流密度和合成电场强度等电磁环境指标，分别给出了其与极间距之间量化的影响指标；分析了空气间隙、V型串长及夹角对直流线路的极间距影响；结合极间距与塔重的关系研究，给出了合理的极间距选择方法.
Abstract:It is very important to select the pole spacing reasonably to control the electromagnetic environment and reduce the construction cost of the DC line project.Aiming at such electromagenetic environment index as radio interference audible noise, ion flux density and eletric field strength, analysis centers around eletromagnetic environment, air gap, V-type length and angle on the pole spacing, offering the quantitative influence index of polar pitch.In combination with the study on the relationship between polar spacing and tower weight, and a reasonable choice of pole spacing is discussed.
