摘要(Abstract)：

总结了220 kV变电站新增3号主变压器的扩建工程中,因主接线由双母接线改建为双母单分段而进行母线差动保护升级改造的工程实施过程,强调了一次、二次物理接线位置对应的重要性,指出了母线差动保护改造过程中的注意事项,可为相关工程提供参考。
The paper summarizes the upgrade transformation of differential protection of busbar due to extension of duplicate-busbar to duplicate-busbar single-segmentation in extension project of the newly-added main transformer 3# in 220 kV substation. It lays emphasis on correspondence of the primary and secondary physical wiring position and indicates precautions in transformation of differential protection of busbar, which can provide reference for relevant projects.
