Abstract The anti-misoperation locking circuit is the last step to prevent the misoperation through analyzing the lockout circuitand the five protection systems of the microcomputer. A variety of methods toget the necessary and sufficient conditions of closing the related switch canbe obtained for the 10kV switching station of three sections and three powersupply. On the basis of it, four design schemes ofthe anti-misoperation locking circuit are proposed for the 10kV switchingstation of three sections and three power supply to prevent the misoperation.
