摘要
考虑线路档距、弧垂等因素的影响,建立了超高压输电线路工频电场三维仿真计算模型,研究了超高压输电线路工频电场分布,分析讨论了线路布置方式、导线悬挂高度、相间距离、导线分裂数、相序及架设屏蔽线等对线路下方工频电场影响的规律和特征。
According to the actual situation of the transmission lines,three-dimensional electric field calculation model was established based on the formula of overhead catenary with sag.Some factors,such as layout,the height of conductors,distance among phase,number of bundles,phase sequence,shielding lines and so on,on the power frequency electric field intensity under the transmission lines were analyzed and discussed.
