摘要
对某光伏电站66 kV六氟化硫气体绝缘全封闭组合电器(GIS)设备的电压互感器(PT)烧毁的原因进行分析,阐述了PT二次侧开口三角故障的隐蔽性和严重性,并针对这一烧毁故障提出了解决方案,以便在光伏电站建设时和后期维护中避免同样故障的发生,确保电站的安全运行。
In the light of a 66 kV GIS PT burned out in a PV power station,this paper analyzes the incident cause,the covertness and the destruction of the failure of the secondary side of the PT.The solution was produced,which can be a reference of avoiding the same failure during the installation and maintenance of PV power station.
