摘　　要：为了确保GIS和HGIS设备的正常运行,在其交接试验和例行试验中可以通过测量导电回路电阻来掌握设备内各电气单元之间的连接或接触状况。考虑到GIS和HGIS设备的结构特点,通过测试多个电气连接单元的总电阻间接判断设备的接触状况。为了能更具体地测量到每个电气连接单元的电阻值,从而更清晰地分析其电气连接状况,以HGIS设备为例,提出一种能够实现GIS或HGIS设备导电回路电阻分段定位测量的方法,并通过Excel软件对某变电站获得的数据进行求解,试验证明计算结果直观可信。To guarantee both （;IS equipment and HGIS equipment working normally, it is necessary to have the information of connec- tion status between one electrical unit and another in equipments by measuring the loop resistance during commission test and routine test. Considering the structural features of GIS equipment and HGIS equipment, it is usual to test the total resistance to estimate the connection status of equipment indirectly. In order to improve the test results of resistanee in every electrical unit, as well as the ana- lyze for electrical connection status, A new method is advanced to achieve testing resistance in part for G1S equip,nent or HGIS equip- ment. Taking the case of HGIS equipment, the new method is clarified by using Excel soft.
