The invention discloses a low-voltage power distribution cabinet provided with low-voltage outlet cables with load current detection devices. The low-voltage power distribution cabinet comprises a 400V low-voltage cabinet body, a cabinet door, three phase wires and a main electric switch. The three phase wires are connected with the low-voltage outlet cables by branch switches. The low-voltage power distribution cabinet is characterized in that each low-voltage outlet cable load current detection device is arranged on the corresponding low-voltage outlet cable; the low-voltage outlet cable load current detection devices are connected with the phase wire B and the phase wire C by the same switching power supply; a cabinet opening detector is arranged on a rotary shaft of the cabinet door. The low-voltage power distribution cabinet provided with the low-voltage outlet cables with the load current detection devices has the advantages that each low-voltage outlet cable load current detection device is directly mounted on the corresponding low-voltage outlet cable in the cabinet, accordingly, inspection personnel can observe load currents of each low-voltage outlet cable without stretching out the hands to carry out optional operation in the low-voltage power distribution cabinet after the cabinet door is opened, effective values of the outlet load currents of the various cables can be directly read from the devices, the low-voltage power distribution cabinet is safe and is high in efficiency and low in energy consumption, and electricity can be saved.
