The invention provides a method and a device for diagnosing zero-line disconnection and phase loss faults of a low-voltage power distribution network. The method comprises the following steps of: S1, respectively acquiring current data at the head end and the tail end of a line; s2, according to the current data of the head end and the tail end, whether an open-phase fault and a zero line breaking fault exist between the head end and the tail end or not is judged; s3, if the open-phase fault or the zero-line fault exists, setting a middle end between the head end and the tail end, collecting current data at the middle end, judging whether the open-phase fault and the zero-line fault exist between the head end and the middle end or not, and judging whether the open-phase fault and the zero-line fault exist between the middle end and the tail end or not; and S4, if the open-phase fault or the broken-zero fault exists, setting a new middle end until the fault position is positioned to a determined ...
