摘要
220k V电网是我国的重要网架,252k V高压GIS设备是保证其安全可靠运行的关键设备。高压套管是GIS的重要组成部分。优化设计252k V高压套管,对于保证252k V GIS安全可靠运行具有重要意义。采用有限元电场分析计算方法优化设计252k V高压套管的绝缘结构,优化其屏蔽罩端部单R形状为多R圆弧过渡,优化后其上电场强度降低12.5%,优化后的252k V高压套管顺利通过了整套绝缘型式试验。
220kV power grid is an important network in China. 252kV (;IS is the key equipment to ensure its safe and reliable service. High voltage bushing is an important component of GIS. Optimization of 252kV bushing is of great signif- icance. The shape of shield is optimized from single-R to multi-R transition with finite element method. The electric field strength on the shield is reduced by 12. 5%. The optimized 252kV high voltage bushing has successfully passed its die- lectric type test.
