一种用于低压直流应用的新型电弧增强轻量化机械开关的超快速混合断路器开发

The hybrid dc circuit breaker (HCB) is crucial for clearing faults and ensuring a reliable power supply in dc grids. However, the fault current can rise rapidly in the low-voltage dc systems, and existing traditional HCB solutions cannot meet the demands of speed and size due to the structure design of the fast mechanical switch and additional assisted commutation devices. In this letter, a novel ...
