摘　　要：圆柱头和圆锥头盘形悬式瓷绝缘子的内、外绝缘性能在理论上无本质差别。相比圆锥头瓷绝缘子,圆柱头瓷绝缘子重量明显减轻,可有效降低杆塔导线的机械载荷;并且对于材料性能经时变化有较好的分散和调整能力,使得产品不受过大应力及不均匀应力的长时作用,具有较高的可靠性。为进一步提升圆柱头绝缘子产品的机械性能,笔者在不改变绝缘子铁帽及瓷件结构的前提下,建立了钢脚参数化的精细仿真模型,通过有限元法计算分析钢脚几何参数对圆柱头瓷绝缘子机械性能的影响,为产品优化提供设计参考。There is no essential difference in theory between the inner and outer insulating properties of cylindrical and conical head disc suspension porcelain insulators. Compared with a conical head porcelain insulator, a cylindrical head porcelain insulator is significantly lighter in weight, which can effectively reduce the mechanical load of the tower and wire;and has better dispersion and adjustment capabilities for changes in material properties over time, so that the product is not subject to excessive and uneven stress over a long-term. In order to improve the mechanical performance of cylindrical head insulator products, the author establishes a parameterized fine simulation model of the steel pin without changing the structure of the insulator iron cap and porcelain body. The finite element method is used to calculate and analyze how the geometric parameters of the steel pin influence insulator mechanical properties, which can provide design reference for further product optimization.
