本文通过实验研究和理论分析,证明采用振动加速度测量技术可以准确迅速地确定气体绝缘组合电器内部放电故障的部位。根据试验研究结果,研制出了故障定位装置,成功地应用于组合电器现场耐压试验时对故障的定位。

This paper presents the results of a study of internal fault location techniques in Gas Insulated Substation (GIS) based on the vibration acceleration caused by the internal faults on the enclosure. The acceleration is measured in order to determin the fault location. Based on the above principle, a new location device was developed which is able to detect the exact location of arc in the GIS during AC withstand voltage test. The results were well proved by the inspection of the GIS.
