摘 要：提出了一种家用智能直流微网的架设结构，介绍了其主要特点。考虑到现实输电线路与负载都包含了少许感性成分，结合参考电压等级设计了一种用于低压配电网的小负荷直流断路器，并通过仿真验证其工作原理。仿真结果表明该断路器可以实现零电流机械开关的常规拉断，还可用作功率路由器的基本模块，为实现能量路由起到了重要作用。

Abstract: This paper put forward the erection structure of a kind of intelligent household direct current (DC) microgrid and introduced its main characteristics. In consideration of the actual transmission line and load containing a few inductive components, combining with the reference voltage level, this paper designed a small load DC circuit breaker for low-voltage distribution network and its working principle was verified by simulation. Simulation results show that the circuit breaker could achieve zero current of a mechanical switching conventional snap and be used as a basic module of power routers, which plays an important role in the realization of energy routing.
Key words: direct current microgrid; direct current microgrid voltage; intelligent direct current circuit breaker; energy routing
