摘要
对水电站3种比较典型的厂用变支路接线进行分析,讨论在厂用变支路分别采用真空发电机断路器、限流熔断器和负荷开关组合以及离相封闭母线直接连接的情况下,厂用变支路的保护用电流互感器参数选择和继电保护配置的解决方案。
Three typical branch connections of service transformer of hydropower station are analyzed. Solutions of CT parameter selection and relay protection arrangement for protection of branch of service transformer are discussed under conditions of respective application of vacuum generator breaker, limiting fuse, load switch combination and direct connection of isolated enclosed busbar.
