摘要
通过介绍六氟化硫(SF6)封闭式组合电器(GIS)结构特点、SF6特点及其绝缘原理,对GIS的检修提出关键节点,并结合某抽水蓄能电厂500 k V主变套管故障引起GIS连接件、均压球及套筒烧损,介绍其检修处理关键点。
In the present paper, the structure characteristics, SF6 features and insulation principle of SF6 Gas Insulated Switch(GIS) are introduced. The key points of GIS overhaul are proposed. A pump storage power station is employed as an example to introduce the overhaul of GIS connections, equalizing ball and sleeve burning caused by 500 k V main transformer casing failure.
