摘要

聚合绝缘子在输电线路中起着至关重要的作用。为确保在高压（HV）条件下安全可靠地运行，它们通常配备有单层或双层分级环，以便沿爬电距离均匀分布电场和电压。本研究采用有限元法（FEM）研究了最佳分级环配置对电场分布的影响。此外，还提出了一种实现最佳分级环设计的适应性方法。数值结果表明，与没有分级环或采用原始设计的绝缘体相比，采用 Nelder-Mead (NM) 优化算法有助于确定分级环材料、尺寸和位置的理想配置，从而实现均匀的电场分布。该方法还适用于不同的环境条件，包括污染、水滴和结冰条件。

Optimal design configuration of grading ring for polymeric insulator under different environmental conditions

Polymeric insulators play a crucial role in power transmission lines. To ensure safe and reliable operation at High Voltage (HV), they are often equipped with single or double grading rings to uniformly distribute the electric field and voltage along the creepage distance. This study investigates the impact of optimal grading ring configurations on electric field distribution using the Finite Element Method (FEM). In addition, an adaptable method for achieving optimal grading ring design is proposed. Numerical results demonstrate that employing the Nelder-Mead (NM) optimization algorithm helps determine the ideal configuration for grading ring material, dimensions, and location to achieve uniform electric field distribution compared to insulators without grading rings or with original designs. This method has also been adapted for different environmental conditions, including pollution, water droplets, and icing conditions.
