摘　　要：12 kV高压开关柜是变电站常用设备,其中的接地开关,传统方式一般以手动操作,效率低,而且容易被操作人员误操作顺序,导致人身伤害事故或影响电网的正常运行。文中提出了一种接地开关的电动操作机构,介绍了其结构、制造工艺有关计算、安装方式等,并列举了实际应用项目。通过分析表明:该电动操作机构能提高效率和安全性,降低手动误操作概率和维护时间,可任意切换手动、电动模式,不仅可用于新工程,也更适合于旧工程改造,以此来推动开关柜程序化控制及智能变电站建设。12 kV high⁃voltage switchgear cabinet is a commonly used equipment in substation,in which the earthing switch is in tradition operated manually with low efficiency and is prone to maloperation sequence by the operators,leading to personal injury accident or affecting normal operation of power grid.In this paper,a kind of motorized op⁃erating mechanism for the earthing switch is proposed,its structure,related calculation of manufacturing process and installation mode are introduced and the actual application projects are listed.It is shown by analysisit that the motorized operating mechanism can not only improve efficiency and safety,decrease manual maloperation probabili⁃ty and maintenance time,but also perform manual and motorized switchover at will.It is applicable for both new proj⁃ect and also for reconstruction of old projects so to promote programmed control for switchgear cabinet and construc⁃tion of intelligent substation.
