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有机复合绝缘子的有限元模型。通过计算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,提出了330k V有机复合绝缘子表面电场优化的措施。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 330kV toughened glass insulator and 330kV organic composite insulator established by finite element analysis. The reference is provided to the investigation of the origin of transmission flashover. Suggestions to establish the technical proposal of the transmission line flashover prevention is also provide.
