摘　　要：依据±800 kV斜撑式干式平波电抗器的基本结构特点,应用二次开发的有限元软件,建立了三维仿真计算模型,进行了电场、电位分布仿真计算,研究了±800 kV斜撑式干式平波电抗器的均压特性,并优化其均压环装置。经优化的结构可以满足±800 kV斜撑式干式平波电抗器的外绝缘要求。Based on the basic structure characteristics of ±800 kV oblique dry-type smoothing reactor,and with the finite element softwqre for secondary development,this paper sets up a three-dimensional simulation model for the calculations of electric field and potential distribution of the reactor.The voltage sharing characteristics of ±800 kV oblique dry-type smoothing reactor are studied,and the composition of its grading rings is optimized.The optimized structure could meet the external insulation requirements of ±800 kV oblique dry-type smoothing reactor.
