摘　　要：目前,发电厂和变电站电气主接线采用3/2接线时,电流互感器二次绕组的配置存在影响系统安全运行或扩大事故范围的隐患。通过分析标准设计中断路器采用瓷柱式断路器、罐式断路器、GIS或HGIS时二次绕组的典型配置方案存在的安全隐患,提出了电气主接线采用3/2接线方案时电流互感器的推荐配置方案,供工程设计参考。Currently, there are problems in current transformer configuration in 3/2 main wiring used by power plants and substations, which might affect safe operation or extends accident scope. Through analyzing hidden troubles in common secondary winding configurations when ceramic post breaker, tip breaker, GIS, or HGIS are used in standard designs, a recommended current transformer configuration using 3/2 bus configuration is proposed. It provids reference for engineering desigus.
