摘要
分析了1 100 k V气体绝缘双屏蔽复合套管各组成部分对套管电气性能的影响,建立数学模型,利用ANSYS软件对复合套管电场分布进行了计算与优化,优化结果表明,在雷电冲击电压下,套管各部分电位分布均匀,套管内部及绝缘子表面场强满足理论要求且裕量充足。该产品已通过全部型式试验,满足了各项技术指标及工程需要。
This paper analyzed the impact of each component part in 1 100 kV gas insulated double shielding composite bushing on electrical properties of the composite bushing, established the mathematical model and used the software ANSYS to carry out calculation and optimization for composite bushing electric ifeld distribution. The optimization result shows that under the thunder and lightning impulse voltage, each part of potential distribution was well-distributed and the interior of bushing and the surface of ifeld intensity of insulators met the theoretical require-ments with enough overmeasure. This product has passed the whole type test and fuliflled the engineering requirement of each technical speciif-cation.
