摘要

针对混合式直流断路器电力电子器件依靠燃弧电压导通，极易出现过压过流等问题，提出了一种新型限流式直流断路器拓扑，设计了其固态开关的均压均流电路，并对其进行建模分析。所提出的拓扑在断路器正常运行时无额外损耗，在短路故障发生时可以无延时地导通固态开关，并快速切断短路电流，其均压均流电路在不影响故障切除的同时能有效均衡各电力电子器件的电压电流。最后对所提拓扑在PSCAD/EMTDC软件平台上进行建模仿真，结果表明提出的新型限流式直流断路器能够在短路故障发生时有效限制短路电流上升，快速切断故障，并可靠地保护固态开关。

Abstract

The conduction of power electronic devices in DC hybrid circuit breakers （CB） relies on arc voltage， which will easily cause overcurrent， overvoltage and other problems. In view of this， this paper proposed a new current-limiting DC CB topology， designed the equalizing circuit of its solid-state switch and carried out the simulation analysis. The proposed topology does not produce loss in the normal operation of CB， and instantaneous trigger solid-state switch with quickly cutting short-circuit current during short-circuit faults. The equalizing circuit can balance the voltage and current of each power electronic devices without affecting the failure removal. Finally， the proposed topology was simulated by PSCAD/EMTDC. The results show that the proposed new current-limiting DC CB can not only limit the current rising rate when the fault occurs， but also cut fault quickly and effectively protect the solid-state switch.
