| 中文摘要 | 了解线路复合绝缘子的轴向电位和电场分布对绝缘子的相关设计和运行维护具有现实意义。为此,利用电磁场有限元计算软件建立了考虑杆塔和导线影响的750kV单回路紧凑型线路复合绝缘子三维模型,计算分析了复合绝缘子在无均压环和安装合适均压环两种情况下的轴向电位和电场分布;计算过程中忽略了伞裙对轴向电场分布的影响。计算结果表明,配置合适均压环后,复合绝缘子轴向电位分布的不均匀性得到有效改善,对金具端部附近场强的控制达到良好效果。最后计算了复合绝缘子伞裙和悬挂方式对电场分布的影响,结果表明,电场分布计算忽略伞裙影响是合理的,且悬挂方式对空间电场分布有一定影响。; It is important for the design and operation of insulators to find out the electric field and voltage distribution along composite insulator string. We discussed the electric field and voltage distribution calculation along composite insulator strings applied in 750 kV compact transmission line. Composite insulator computation models considering the effects of tower and conductors were set up using FEM software system. The electric field was calculated in the circumstances of insulators with and without grading ring. The results show that the nonuniformity of voltage distribution along the axis of insulators is improved and the maximal electric filed strength around end fitting is reduced after the application of the grading rings. In addition,the calculation results show that possible model simplifications with weather-sheds omitted in the model of this paper are reasonable for calculation of electric field distribution along the axis of insulators. Suspension patterns of insulators have influence on the distribution of electric field in the space. |
