| Abstract: | Based on the operation reliability thetechnical feasibility of eliminating the closing resistorsfor 500kV circuit breakers is studied.The differencesof switching surge overvoltages in both the situationsof the overvoltage reduction schemes with MOA andclosing rexistor and that with MOA only, are com-pared. The difference in flashover rate of line insula-tion with these two schemes is analyzed and studied indetail. The conditions for eliminating the closing resis-tors for 500kV circuit breakers are discussed and someuseful suggestions on this problem are put forward. |
