| Abstract: | In order to increase the success rate of recloser of 220 kV and above voltage level transmission lines in multiple faults,by analyzing reasons of the recloser failure of a certain 220 kV transmission line and exposed problems,measures to increase the success rate of recloser are found such as changing the charging time of protection equipment,using operating mechanism which has multiple operations with one energy store operation,choosing reasonable reclosing mode and so on,which have practical guide significance for avoiding the power off of important lines in areas with high lightning density. |
