【摘要】：均压环是改善复合绝缘子电位分布和电场分布直接而有效的方式,在特高压输电系统中极其重要。为此,对特高压直流复合支柱绝缘子的电位分布和电场分布进行了计算,引入了大均压环表面、护套沿面、高压端金具表面和小均压环表面等处的最大电场强度作为优化参考量,并探讨了各均压环参数和各优化参考量间的联系,分析了大小均压环各参数优化的相互影响,拟定了大小均压环各结构参数的优化顺序,提出了特高压直流复合支柱绝缘子均压环优化方法。并以±1 100 kV直流空心复合支柱绝缘子和±800 kV直流实心复合支柱绝缘子为例,建立了电场计算模型,对其均压环进行了优化设计。改进后的优化方法能够较快、有效地找到满足条件的优化方案。
[Abstract]:Voltage sharing ring is a direct and effective way to improve the potential distribution and electric field distribution of composite insulators, which is very important in UHV transmission system. For this reason, the potential distribution and electric field distribution of UHV DC composite support insulator are calculated. The maximum electric field intensity at the surface of the high pressure end metal tool and the surface of the small uniform pressure ring is used as the optimum reference. The relationship between the parameters of the uniform pressure ring and the optimized reference quantity is discussed, and the mutual influence of the parameters of the large and small uniform pressure ring on the optimization is analyzed. The optimization order of the structural parameters of the large and small voltage equalizing rings is worked out, and the optimization method of the UHV DC composite support insulators is presented. Taking 卤1 100 kV DC hollow composite post insulator and 卤800 kV DC solid composite support insulator as an example, the electric field calculation model is established, and the optimum design of the voltage equalizing ring is carried out. The improved optimization method can find the optimization scheme which meets the conditions quickly and effectively.
