摘要
分析了纵联差动继电器的工作原理和不平衡电流流过纵联差动保护对保护的影响,并重点分析了牵引变压器空载合闸和电流互感器电流比,得出了一些改善措施。
The paper analyzes the working principles of longitudinal differential relay and influences to the longitudinal differential protection when the unbalance current is passing through, analyzes with emphasis on no-load closing of traction transformer and current ratio of current transformer, and certain improving measures are obtained.
