摘　　要：采用常规的电气试验方法对气体绝缘金属封闭开关设备(GIS)进行检测受到很多限制。介绍了用于GIS局部放电检测的特高频局部放电检测系统的组成、工作原理及选用范围。该技术应用于实际生产现场状态监测工作的实践证明,其有利于GIS运行状态评价。There are many limitations to check the gas insulated metal-clad switch gear （GIS） with the common electric experiment methods in many aspects. This paper introduces the composition, working principle and selection scope of the ultra high frequency partical discharge check system used in checking the partial discharge of GIS. The application of this technology in practical onsite condition check has proven that this system is helpful to evaluate the operating condition of GIS.
