摘　　要：针对如何解决主变压器保护旁路运行时启动失灵保护的问题,提出一种可行的主变器高压侧开关旁路运行时启动失灵保护的接线方案,在主变压器高压侧开关旁路运行主变压器故障时,仍然可以启动失灵保护。In order to start up failure protection when the main transformer bypass bus operates, a feasible line connection scheme in terms of failure protection start-up is put forward so that when failure occurs on high voltage side switch, failure protection can be started up.

关 键 词：主变器旁路运行 开关失灵保护 改造
