摘　　要：根据不同电位梯度的电阻片,提出了一种具有创新性的1 000 kV GIS用避雷器结构。采用经过二次开发的有限元、边界元数值计算方法并应用具有强大实体造型、解算、数据分析和后处理功能软件及工作站对初步设计的避雷器结构进行了电位分布仿真计算及抗震性能仿真计算,确定了理想的避雷器均压结构及整体结构。并采用电流法对避雷器电位分布情况进行了实测试验,通过对试验数据进行整理及分析,最终确定了合理的避雷器结构。An innovative surge attester for 1 000 kV GIS is proposed based on varistors of different potential gradients. Through the potential distribution simulation and the anti-seismic performance simulated calculation on the preliminary designed surge arrester is carried out, which is based on the secondary development finite element, boundary element numerical calculation method and the post-processing function software and workstations with powerful modeling, solver, data analysis, the ideal grading structure and overall structure of arrester are determined. Tests on the potential distribution status are carried out by using current method, through collation and analysis on test data, the rational structure of surge an＇ester is finally determined.
