摘要
输电线路绝缘子闪络已经成为影响供电可靠性的重要因素,采取相关防污闪措施已经成为必须。本文基于静电场理论,采用有限元数值计算方法,建立了330k V钢化玻璃绝缘子的有限元模型。计算了杆塔及导线对绝缘子周围电场的影响、绝缘子表面电场分布和绝缘子表面电场强度分布。
Flashover of transmission line insulator has become an important factor which influences the reliability of power supply. In this paper, based on electrostatic field theory, finite element models of 330 k V toughened glass bead are established by finite element numerical calculation. Through calculations of the influence on the electric field surrounding the insulator, surface electric field distribution and surface electric field intensity distribution of the insulator, measures to optimize the surface electric field of the 330 k V toughened glass bead are proposed.
