The invention relates to a power distribution device with a ground fault protection function and a power distribution method. The power distribution apparatus may include one or more power distribution controllers and a processor coupled to each power distribution controller. Each power distribution controller can comprise one or more groups of power control units and one or more corresponding cross-core current transformers. And each group of power control units comprises three power control units. Each cross-core current transformer can be used for sensing cross-core current of three-phase output current of the three power control units corresponding to the cross-core current transformer. The processor may be configured to receive a sensed cross-core current from a cross-core current transformer; and transmitting a turn-off signal to each of the three power control units if the sensed cross-core current is not equal to zero. According to the power distribution device disclosed by the invention, the grounding fault protection function can be realized without changing the architecture of the existing power distribution device, and the safety of a power supply network is improved.

    本公开涉及具有接地故障保护功能的配电装置和配电方法。该配电装置可包括:一个或多个配电控制器以及耦合到每个配电控制器的处理器。每个配电控制器可包括:一组或多组功率控制单元以及对应的一个或多个穿心电流互感器。每组功率控制单元包括三个功率控制单元。每个穿心电流互感器可用于感测分别由与该穿心电流互感器相对应的该三个功率控制单元的三相输出电流的穿心电流。该处理器可被配置成从穿心电流互感器接收经感测的穿心电流;以及在经感测的穿心电流不等于零的情况下,向该三个功率控制单元中的每一者传送关断信号。根据本公开的配电装置能够在不改变现有配电装置的架构下实现接地故障保护功能,提高了电源网络的安全性。
