随着DC电网发挥重要作用的脱碳社会的趋势，DC断路器的重要性日益增加。本文提出了一种采用高速直线电机的高速熔断器开关的熔断器-半导体混合式断路器的概念。作者证明了所提出的概念的可行性，成功地实现了电流限制，电流中断，保险丝交换，并重新关闭的故障电流的幅度约为6.0 kA。中断在3.4 ms内完成，在66.9 ms内重新关闭电力系统。短中断时间可将过流和停电对负载设备的损坏降至最低。所提出的操作原理有可能在中断额定值、成本和尺寸方面提出新的折衷，因为保险丝、半导体和压敏电阻补偿彼此的缺点。此外，快速熔断器更换器解决了熔断器一次性使用的缺点。此外，设计参数的权衡，选择器件的额定值的方法，以及扩大规模的挑战进行了详细讨论。
With the trend toward a decarbonized society where DC power networks play an important role, the importance of DC circuit breakers is increasing. In this paper, the concept of a fuse-semiconductor hybrid circuit breaker with a high-speed fuse exchanger using a high-acceleration linear motor has been presented. The authors demonstrated the feasibility of the presented concept by successfully achieving current limitation, current interruption, fuse exchange, and re-closing for fault currents with a magnitude of approximately 6.0 kA. The interruption was completed in 3.4 ms and re-closed the power system in 66.9 ms. The short interruption time can minimize damage to load equipment owing to overcurrent and power failure. The proposed operating principle has the potential to present new tradeoffs in interrupting ratings, cost, and size because a fuse, semiconductor, and varistor compensate for each other's shortcomings. Moreover, the single-usage disadvantage of the fuses was solved by the fast fuse exchanger. In addition, tradeoffs in design parameters, methods for selecting devices' ratings, and challenges to scale up are discussed in detail.
