【摘要】 采用有限元法计算了加装均压环后的电场分布,结果表明,外加均压环的均压效果较好。均压环不但能改善电场分布,而且还有引弧、防止金具电晕、延缓芯棒老化等作用;最后探讨了均压环设置应该注意的问题。更多还原

【Abstract】 Based on the research of electric field of composite insulator,finite element method is applied to calculation of electric field after setting up grading rings,The results shows the effect of their setting is very good;The grading ring can not only improve the electric field,but also guide arc?avoid corona discharge?delay the core aging of composite insulators and so on,finally several setting up problems concerning of grading rings setting are discussed.更多还原
