摘　　要：当前的防误闭锁装置标识结构一般设定为独立模式,导致误操作误识率增加。根据当前的测定需求分析变电运行中电气误操作事故原因,设置运行监测节点及管控机制,采用多层级的方式提升防误操作效率。在此基础上,构建多层级的防误闭锁装置,采用二次核验的方式来完成误操作事故处理,从而实现电气误操作事故应对。最终的测试结果表明,随机选定的6台辅助电气设备的误操作率均被控制在15%之内,此次制定的应对措施更加完整、有效,能有效降低电气误操作事故的发生概率。The current identification structure of anti-misoperation locking devices is generally set to independent mode,which leads to an increase in misidentification rate.According to the measurement requirements at present,this paper analyzes the causes of electrical misoperation accidents in operating substations,sets up operation monitoring nodes and control mechanisms based on the analysis results of electrical misoperation accidents,and adopts a multi-level approach to improve the efficiency of preventing misoperation.On this basis,a multi-level anti-misoperation locking device identification structure is constructed,and a secondary verification method is adopted to complete the handling of misoperation accidents,thereby facilitate coping with electrical misoperation accidents.For the as experimental subjects,The proposed countermeasures achieves in test performed on randomly selected 6 auxiliary electrical equipment misoperation misidentification rates lower than 15%,indicating that the designed measures are more complete and effective,and can effectively reduce the probability of electrical misoperation accidents.
