摘　　要：本文通过对防误闭锁电路和常用微机五防系统的分析,得出防误闭锁电路是防误操作的最后一道防线。然后针对单母三分段三电源的10k V开关站,用多种方法得出了相关开关可合闸和禁止合闸的充分必要条件,在此基础上,提出了三电源单母三分段10k V开关站实现防止并列运行操作的四种防误闭锁电路设计方案,以供配网生产运行者参考学习。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 10 k V 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 10 k V switchingstation of three sections and three power supply to prevent the misoperation.
