摘　　要：覆冰在绝缘子中多有发生,研究不同覆冰长度对绝缘子电位的影响,对绝缘子除冰工作有一定指导意义。以110 kV复合绝缘子为例在ANSYS中建立其仿真模型,基于有限元静电场模型分析了不同的覆冰长度对绝缘子表面电位分布的影响。结果表明:洁净FXBW-110/100型复合绝缘子表面电位分布是极其不均匀的,覆冰长度小于60 cm时对绝缘子表面电位影响不大,覆冰长度达到70 cm时覆冰末端点位分布畸变严重,覆冰长度达到80 cm时表面电位分布的不均匀性得到明显改变,绝缘子表面整体电位发生严重畸,绝缘性能严重下降。The phenomenon of Icing on Insulators was common in power system, therefore the research on and the influence of them on potential is important to clear ice on Non-ceramic Icing Insulators. A 110 kV Non--ceramic Insulator was built in ANSYS, and the influence of the length of ice on surface electric field and potential. The result indicates that： the potential distribution of insulator is not well distributedz under 60 cm icing do not change holistic electric field and potential distributionl holistic electric field and potential distribution changed when the icing is upio 70 cm; icing potential distribution is changed obviously and the insulation capability declined obviously if the length is upto 80 cm.
