摘要
通过ANSYS软件建立10 kV电缆冷缩式中间接头的三维模型,并仿真计算静电场,主要分析不同受潮情况下电场分量的分布情况。结果表明:接头绝缘材料受潮时,复合界面上的电场增大;接头浸水时间越长,电场畸变越严重;主绝缘内侧受潮时水膜对周围的电场分布几乎没有影响,水膜处电场增大,但场强依然保持在极低的水平。
This paper establishes the three-dimensional model of 10 kV cable cold shrinkable intermediate joint by ANSYS software,and carries out the electrostatic field simulation calculation,mainly analyzes the distribution of electric field components under different moisture conditions.The results show that the electric field on the composite interface increases when the joint insulating material is damp;The longer the immersion time is,the more serious the electric field distortion is;When the inner side of the main insulation is affected by moisture,the water film has little effect on the electric field distribution around it.The electric field at the water film increases,but the electric field strength remains at a very low level.
