摘要
为研究特高压直流输电线产生的磁场对人体及通讯设备、自然环境等的影响,利用ANSYS有限元软件建模,对±800 kV直流输电线路采用八分裂输电导线时,不同电流等级情况下产生磁场的分布规律及其数量级进行了分析。通过理论数据与国际相关限值的比较可知,该输电线路产生的磁场对周围环境以及对人体都没有危害。
In order to study the influence of the magnetic field generated by the ultrahigh vohage DC transmission line on human body, communication equipment and natural environment, this paper establishes the model by AN- SYS finite element software to analyze the distribution law of magnetic field generated by different level of current with the apphcation of the 8-bundled conductor and its order for ＋ 800 kV DC transmission line. Through the com- parison of the theoretical data and the relevant international limiting value, the result shows that the magnetic field generated by the transmission line is harmless to environment and human body.
