摘　　要：GIS设备全封闭结构导致故障检查相对复杂,如何快速准确判断出GIS故障形成原因,缩短停电时间,一直是现场技术人员十分关心的问题。笔者介绍了一例由于安装工艺引起的SF6气体绝缘开关设备(GIS)接地故障。文中通过详实的试验与现场调查,分析故障产生原因,同时对GIS缺陷早期发现与交接试验提出了建议。G/S is fully enclosed structure, and it is more complex troubleshooting. GIS quickly and accurately determine the causes of failure to reduce outage time. This is the questions that engineering personnel are very concerned about. This article introduces a breakdown of gas-insulated metal-enclosed switchgear, which is due to installation process. the same time some Through the detailed experiment and field investigation, the failure causes are analyzed, at suggestions for the early detection of GIS defects and commissioning test are put forward.
