摘　　要：以Maxwell2D为有限元法求解工具,建立工频电压下的XLPE电缆终端数值计算模型,同时考虑了介质介电常数和电导率对电场分布的影响,计算分析了几种应力锥结构尺寸下电缆终端内部的电场分布,得到了应力锥结构尺寸与电缆终端内部电场分布的关系,为应力锥结构尺寸的合理设计提供了理论依据。Taking Maxwell2D as a calculation tool of finite element method, this paper built a numerical model of XLPE cable terminals under AC voltage. Electric field distributions in cable terminals, under several dimensions of stress cone structures, were calculated by considering the influence on electric field distribution of the medium＇s dielectric constant and electric conductivity. The relationships between dimensions of stress cones structure and the electric field distribution were obtained.
