摘　　要：针对鄂州220 kV郎沙单回输电线路,基于有限元法和APDL参数化语言,研究并分析地线、导线对地高度、导线参数、相间水平距离和相间垂直距离等影响因素对线路周围的电场强度及磁感应强度的影响。计算结果表明,导线对地高度对工频电场强度及磁感应强度的影响较之其它影响因素尤为明显。Aiming at Ezhou 220 kV Langsha single circuit line,the influential factors on electricfield strength and magnetic induction intensity were studied based on the finite element method andAPDL(ANSYS Parametric Design Language),which included ground wire,conductor heights toearth,conductor parameter,inter-phase horizontal distance and inter-phase vertical distance.Theresults showed that the conductor heights to earth influenced more on electric field strength andmagnetic induction intensity than the other factors.
