Power distribution unit

A power distribution unit, comprising:

• three monophase sockets, wherein, among the three monophase sockets, any target monophase socket is configured to be connected with an electrical apparatus conforming to voltage of the target monophase socket;
• a star-connected switching circuit connected with three phase windings on a secondary side of a distribution transformer and the three monophase sockets;
• a delta-connected switching circuit connected with the three phase windings and the three monophase sockets;
• and
• a controller, wherein the controller is connected with the star-connected switching circuit and the delta-connected switching circuit, and configured to correspondingly control the star-connected switching circuit or the delta-connected switching circuit to be turned on according to a current three-phase power wiring requirement of the power distribution unit, so that the three phase windings are connected according to a target wiring mode conforming to the three-phase power wiring requirement, and three phase power under the target wiring mode is supplied to the three monophase sockets respectively.
