摘　　要：文中介绍了72.5 kV及以上气体绝缘金属封闭开关设备(简称GIS)常用的3种结构类型的三工位隔离接地开关:双导电杆连杆传动的三工位隔离接地开关、滚珠丝杠传动的三工位隔离接地开关、齿轮齿条传动的三工位隔离接地开关。这3种三工位隔离接地开关有别于传统的旋转闸刀式结构,都是属于国内外主流的动触头直动插入式结构。通过对这3种三工位隔离接地开关结构、滑动电联接形式以及运动形式的阐述,分析了各种结构的优势,为GIS核心模块部件的改进和优化设计提供技术指导。Such three types of three-position disconnector and earthing switches as the three position isolating earth-ing switch driven by double conducting rod connecting rod,by ball screw and by rack and pinion,which are common-ly used in GIS at 72.5 kV and above,are described in this paper.These three types of three position isolating ground-ing switches are different from the traditional blade rotary strcuture,which are the mainstream type of moving contact plug-in both at home and abroad.Through the description of the structure,sliding electrical connection form and movement form of the three three position isolated grounding switches,the advantages of each structure are analyzed,which provides technical guidance for the improvement and optimization design of the core module components of GIS.
