摘　　要：GIS组合电器与传统敞开式电气设备相比较,有很多明显的优越性。但由于其所有元件均处于封闭金属壳体内,运行人员无法直接观察设备运行状态,只有通过各种遥测、遥信信号及机械位置指示来间接反映GIS内部元件实际工况。通过某变电站GIS操作过程中出现故障的分析和判断,说明值班员应充分重视GIS操作过程中出现异常现象,只有这样才能有效避免事故发生。Although GIS has many obvious advantages compared with the traditional opened one, the actual performance of the components inside can only be measured by some remote measurements and remote signals or by mechanical location indicator indirectly, as all of the components are placed in a hermetic metal shell. GIS substation operation through a process of failure analysis and determine that duty should pay full attention to operation of the process of GIS abnormal phenomenon, the only way to effectively prevent the accident.
