| 摘 要： | 根据SF6气体绝缘电流互感器的产品结构方案，计算了简化结构模型的三维电场分布，给出了不同截面的电位分布图形，确定出合理的330kVSF6气体绝缘电流互感器绝缘结构形式和结构尺寸，指出只要选定 合适的截面，二维场计算结果与三维场计算结果差异很小,在工程上可采用二维场计算以缩短设计周期。

| Abstract: | According to the structure of a SF 6 gas insulation current transformer, 3-dimensional electric field distribution of simplified structure model is calculated, the potential distribution graphs in different sections are presented, and the type and size of reasonable insulation structure in a 330kV SF 6 gas insulation current transformer are determined. It is concluded that as long as suitable section is selected, the result calculated with 3-dimensional field is similar to 2-dimensional field. The design period can be reduced by 2-dimensional field calculation in engineering. |
