| Abstract: | An innovative surge arrester 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 arrester is finally determined. |
