摘　　要：本文利用COMSOL Multiphysics有限元仿真软件仿真了绝缘子在加装均压环前后周围电场的情况,证实了复合绝缘子加装均压环确实能够解决输电线路中电场集中的问题,为输电线路安全稳定的运行提供理论基础。The COMSOL software was used to simulate the electric field around composite insulator. The results show that adding grading ring to composite insulators can really decrease the electric field concentration. The conclusion of simulation provides a theoretical basis for the safe and stable operation of the transmission line.
