浅谈全封闭组合电器接地技术及相关问题探讨

Discussion on grounding technology and related problems of fully enclosed combined electrical appliances

全封闭组合电器(GIS)由于自身稳定可靠的运行优势,被广泛应用到了电力系统中。不过,GIS设备对接地设置的要求较高,如果接地不良就有较大的概率导致接地故障发生。为了降低接地不良故障的发生率,将针对GIS设备特点及相关问题进行探讨。

Gas insulated metal-enclosed swit-chgear (GIS) is widely used in power system because of its stable and reliable operation advantages.However,the requirements for grounding setting of GIS equipment are high.If the grounding is poor,there is a high probability of grounding fault.In order to reduce the incidence of poor grounding fault,the characteristics of GIS equipment and related problems will be discussed.
