介绍了一起由于导电杆未安装到位，致使导电杆与触指接触不良，触头发热熔化，最终造成母线导体对外壳放电的单相接地短路故障。通过对气体绝缘全封闭组合电器（GIS）接头结构的分析，对GIS触头连接不良缺陷的早期发现与交接试验提出了建议。

A ground fault arisen by the poor contact is introduced in this paper. Because the installation of the conducting rod was not in place, the bad contact leads to the heating and melting of the contacts, resulting in the single-phase ground fault. Based on the analysis of the structure of GIS contact, several proposals are put forward for the early detection of the bad contacts of GIS and the handing over test.
