摘要
为了有效检测出GIS避雷器气室内存在的局部放电缺陷,提高GIS设备运行可靠性。介绍了一起GIS避雷器带电检测案例,分析了带电检测过程中发现的异常情况和跟踪检测情况,并解体验证了检测和定位结果的准确性。最后探讨了多种带电检测手段对于GIS避雷器的适用性,本案例的带电检测经验可以为GIS避雷器的运维检修提供一定的参考和指导。
In order to detect the partial discharge defects in the gas chamber of the GIS-insulated surge arrester effectively and improve the reliability of the GIS equipment operation. The author has introduced a GIS-insulated surge arrester live detection case, analyzed the abnormal result and tracking detection result, and verified the accuracy of the detection and positioning result. Finally, the applicability of various live detection methods to GIS-insulated surge arresters is discussed, which provides a certain reference for the operation and maintenance of GIS-insulated surge arrester.
