中文摘要	通过比较外加Laplace电场和Possion电场的Kerr效应光斑图像,可以定性了解沿面闪络前绝缘子表面电场的畸变程度。为此,提出了一种Laplace场Kerr效应光斑图像的计算方法,并通过该方法获得了平板电极之间Kerr液体间隙的Laplace场光斑图像。将所得计算图像与同一间隙在线测量得到的Laplace场光斑图像进行对比,证实了该计算方法的有效性。计算结果表明:空间的电场分布与激光的光强分布存在唯一对应关系;在100 kV电压下,平板电极间由Kerr效应引起的激光光强呈对称条纹分布,出现4级亮条纹且条纹向中心弯曲。; By comparing the Kerr-effect light spot images produced by Laplace electric field and Possion electric field, we can qualitatively grade the distortion of the electric field along an insulator surface before flashover. Therefore, we put forward a method for calculating the Kerr-effect light spot image produced by Laplace electric field, through which we obtained the light spot image produced by Laplace electric field in a gap of Kerr liquid between plane-parallel electrodes. We compared the calculated image and the experimentally measured light spot image produced by Laplace electric field in the same gap, and it proves that the method is valid. The calculation results showed that, the special distribution of electric field is solely corresponding to the light intensity distribution of laser, for example, the light intensity distribution caused by the Kerr effect between two plate electrodes with 100 kV voltage shows as symmetrical stripes, with four of them bright and all of them bending to their center.
