摘要
对电缆附件的复杂结构进行数值计算,并通过计算结果对应力锥形状进行优化设计,从而改善附件场强集中部分的电场分布,提高电缆附件的使用寿命。开发的软件包对不同的应力锥形状下的场强采用有限元方法进行计算并提供以下功能:画出任意电位的等位线;用不同颜色填充附件内部,通过颜色深浅显示场强大小;对附件内部任意一点提供用鼠标点击显示该点坐标、该点电位和该点场强;给出整个附件内部区域切向场强和径向场强的最大值和坐标值。
The complex structure of electric cable accessory is calculated by finite element method. In order to improve the distribution of electric field and increase the operating life of electric cable accessory, optimization designing of stress cone shape has been carried out based on the calculation results. This software package can calculate electric field in different stress cone shape by finite element method, and can present following functions： drawing equi-potential line ; displaying electric field value with different color; displaying coordinate, vohage and electric field value of any point pointed by mouse; displaying maximum and minimum of the tangential and radial electric field in whole area.
