中文摘要: 基于有限元法,计算了上海市南电力公司正在建设的长兴-步泾变电站间架空线附近的电场分布.根据国内对工频电场曝露限值的标准,评估了输电线路对电磁环境的影响,提出了降低场强可采取的措施和检修作业时的防护方法.研究了采用屏蔽线时线下场强的变化,指出架设屏蔽线能够明显降低线下场强.

Abstract:The finite element method has been applied to calculate the 50Hz electric fields nearby the transmission lines between changxing substation and bujing substation，which are erecting by Shanghai South Power Supply Company.According to the domestic security standards of 50Hz electric field， the impacts of overhead transmission lines on environment are evaluated， the adoptable measures to reduce electric field strength and proposals for further protection measures during maintenance operation are proposed.Besides，the influence of adopting shield wire on electric field strengths below transmission line is analyzed and it is pointed out that adopting shield wire can take effect of reducing electric field strengths below overhead transmission line.
