摘　　要：采用一种新的模拟面电荷—表面电荷法对研制的两种５００ｋＶ悬挂式ＺｎＯ避雷器阀片柱沿面电位分布进行了计算。计算与现场实测结果进行对比，验证了计算结果的正确性。The 500kV gapless ZnO surge arrester includes multilayer dielectric and many electrodes with suspension potential. When it is suspended on the 500kV transmission tower, the computation of the varistor voltage becomes a difficult problem in the computation of three dimensional electric field. In this paper, the electric field distribution along the ZnO varistor post of the surge arrester is calculated by the new surface simulation charge-surface charge method successfully. Comparing the measured data with calculation results, it is proved that the calculation method is correct.
