| Abstract: | The actions of 110kV backup self- switching equipment and 10kV backup self- switching equipment after a fault are analyzed, and a conclusion about the cooperation between these two backup self- switching equipments is obtained. The discharge delay of lOkV backup self-switching equipment must be reasonably set, so that 10kV backup self-switching equipment cannot be discharged in the course of the actions of llOkV backup self- switching equipment, and it can avoid the extension of power interruption. |
