摘　　要：GIS组合电器已广泛应用于电力系统,为了能更好的解决GIS设备的长距离母线在运行后水平位移与垂直位移问题,现场采用的方法是增加伸缩节和水平滑块。本文总结750kV兰州东变电站3年多的运行经验,分析了伸缩节和水平滑块的应用效果,并提出利用主刚固定支架、伸缩节、滑块支架与次刚固定支架配合的方法来解决长母线筒端部位移问题,最后给出了伸缩节位移的模型,并与实际数据对比分析。Gas Insulated Substation（GIS） has been widely used in power systems.In order to resolve the question of horizontal displacement and vertical displacement after the long-distance bus operating,there is the way that adds to expansion joints and sliding supports.Summarizing the 3 years experience of 750kV Lanzhou Dong Substation,this article proposes the application of expansion joints and sliding supports.The paper presents the conclusion that using the main-stationary support,the sliding support,expansion joints and the second-stationary support to solve the displacement of long-distance bus enclosure.Finally,it gives the model of expansion joint-displacement,and compares with the actual value.
