Surface Field Strength Calculation and Optimization of Tri-post Insulator on GIL

GIL中三支柱绝缘子是重要的绝缘支撑元件,其绝缘可靠性关乎输电系统的整体安全。本文运用有限元法开展GIL三支柱绝缘子建模和电场分析计算,重点分析电场沿切向分量的计算方法,根据该方法设计出经济可靠的绝缘结构。通过参数扫描法开展绝缘子结构优化设计,为产品研制提供理论依据和设计指导。

Tri-post Insulator is one of the most important component in GIL,the reliability of insulate effect power system safety. In this paper, we established a model of tri-post insulator and calculate the electric field, studied the surface field strength calculate method. The optimum design of insulator structure was carried out by parameter scanning method, which provided theoretical basis and design guidance for product development.
