摘要
以扩大内桥接线方式为例,介绍了比率制动特性的变压器纵联差动保护原理,并分析了扩大内桥接线方式各种故障情况下变压器纵联差动保护动作行为,并根据现场实际运行情况,提出了一些现场注意事项,以便更好的指导实际生产运行。
Taking the expanded inter-bridge connection mode as the example, this paper introduces portraitunite differential protection theory of transformer that has ratio restrained characteristic, and analyses the longitudinal differential protection behavior when all kinds of failures happen in expanded inter-bridge connection. Farthermore, according to the actual operational cases, this article proposes some items needing to be noticed in order to guide the actual production operation.
