| 摘 要： | 设计了一种集成电路型具有二次五次谐波制动的变压器差动继电器。它可以作单个继电器用,具有穿越电流制动回路,无制动速断回路,且可防止空投变压器励磁涌流的影响,对大容量变压器还可躲开过励磁运行时五次谐波的影响;它也可与负序电流突变量起动元件配合,构成一套变压器主保护。 |
| 关 键 词： | 集成电路 二次五次谐波制动 变压器 |

| Abstract: | An integrated-circuit transformer differential relay including secondary and fifth harmonics suppressor is designed. It can be used as an independent relay, including crossing current brake circuit, no braking quick-break circuit, preventing no-load starting transformer inrush current, and avoiding fifth harmonics of overexcitation running for high-power transformer. It can be combined with a set of transformer main protection by combining negative-phase sequence current sudden-change starting element. |
| Keywords: | integrated-circuit secondary and fifth harmonics suppressor transformer |
