Study on the Effect of Human Body's Industrial Frequency Electric Field by Ultra-High Voltage Transmission Lines

在我国电力系统领域中,对特高压输电系统的研究越来越重视。输电线周围区域的工频电场强度受输送的电压幅值影响,当幅值较大时,其产生的强电场会对人体产生危害。文中使用三维仿真软件建立输电线和人体仿真模型,对人体周围区域的工频电场强度和电流密度分布进行模拟仿真,分析其受输电线的影响规律;并依据相关限值标准,结合仿真得到的输电线路电场分布云图,提出了输电线路下的安全区域。

In the field of China's power system,the research on the ulra-high voltage transmission system has been paid more and more attention.The intensity of the industrial frequency electric field in the area around the transmission line is affected by the amplitude of the voltage delivered,and when the amplitude is large,the strong electric field it produces can be harmful to human beings.In the paper,three-dimensional simulation software is used to establish a simulation model of transmission lines and the human body,simulate the industrial frequency electric field strength and current density distribution in the region around the human body,and analyze the pattern of its influence by the transmission line.In addition,based on the relevant limit value standards,and combined with the transmission line's electric field distribution cloud map which obtained by simulation,the safe area under the transmission line is proposed.
