摘 要：針對(duì)現(xiàn)有隔離接地三工位操作裝置的隔離和接地部分操作復(fù)雜、傳動(dòng)結(jié)構(gòu)復(fù)雜、零件多、成本高等問題，設(shè)計(jì)了一種高壓柜隔離接地三工位操作裝置。該裝置高壓柜母線的隔離、接地和接通狀態(tài)能夠連續(xù)操作切換，解決了誤操作問題，通過使用軟軸接地傳動(dòng)模塊，簡化了傳動(dòng)結(jié)構(gòu)從而降低了生產(chǎn)成本，經(jīng)實(shí)際工程項(xiàng)目應(yīng)用，獲得了較好的經(jīng)濟(jì)效益。

Abstract: The existing three-position disconnecting/earthing operating device has shortcomings, such as the inconvenient operation of disconnector and earthing switch, cumbersome transmission structure, much more parts and high costs. To solve these problems, an advanced three working position disconnecting /earthing operating device for high voltage switchgear is designed in this paper. It can continuously switch the operation to disconnecting,earthing, or making and consequently prevented misoperations. Additionally, the utilization of the earthing flexible driving shaft simplified the transmission structure and reduced the cost of production. Finally, this device is proved cost-effective by applying to some practical projects.
Key words: high voltage switch cabinet; three working position switch; operating device; disconnector; earthing switch
