摘　　要：直流穿墙套管作为直流输电系统的关键设备,长期以来依赖进口,对其研究具有重要意义.本文基于GB/T 26218.3—2011《污秽条件下使用的高压绝缘子的选择和尺寸确定第3部分:交流系统用复合绝缘子》及《±1100千伏特高压直流输电工程设备研制技术规范》,对昌吉—古泉±1100kV特高压直流输电工程直流穿墙套管伞裙型式、伞形参数等进行了研究,给出直流SF6穿墙套管伞裙结构型式及伞形参数设计规范.根据研究结果给出户外侧昌吉—古泉±1100kV特高压直流输电工程直流SF6穿墙套管伞裙结构及参数,对±1100kV直流SF6穿墙套管的研制具有重要指导作用,也可为其他相关工程提供参考.As the key equipment of HVDC transmission system, dc wall bushing has long been dependent on imports, which is of great significance to its research. Based on GB/T 26218.3-2011 "Selection and dimensioning of high-voltage insulators in-tended for use in polluted conditions Part 3: Composite insulators for a.c. systems" and "The equipment development specification of ±1100kV UHVDC transmission project-converter wall bushing". We investigated the umbrella the structural type and design specification of umbrella skirt of the Changji-Guquan ±1100kV UHVDC transmission project. Ac-cording to the research results, the structure and parameters of the umbrella skirt with outdoor DC SF6 wall bushing for the Changji-Guquan ±1100kV UHVDC transmission project. It has an important guiding role for the development of ±1100kV DC SF6 wall bushing and can also provide reference for other related projects.
