The invention discloses a high-voltage and low-voltage dual-purpose shipborne shore power system which comprises a high-voltage and low-voltage shore power socket conversion box, two cable winches, a high-voltage shore power connection cabinet, a high-voltage shore power transformer, a main distribution board and a low-voltage shore power junction box. When high-voltage shore power needs to be connected, a high-voltage butt joint part of one cable winch is connected with a wharf high-voltage shore power socket box through a high-voltage shore power cable and connected with a high-voltage shore power connection cabinet, and the high-voltage shore power connection cabinet is connected into a high-voltage shore power screen of a main distribution board of a ship through a high-voltage shore power transformer. When low-voltage shore power needs to be connected, the high-low-voltage shore power socket conversion box is connected into a wharf low-voltage shore power socket box and used for converting a wharf low-voltage shore power socket into a high-voltage shore power socket, the other cable winch is switched to the low-voltage butt joint part, and a cable of the cable winch is connected into the high-low-voltage shore power socket conversion box and used for converting the wharf low-voltage shore power socket into the high-voltage shore power socket. Therefore, the low-voltage shore power of the wharf is connected to the low-voltage shore power screen of the main distribution board of the ship through the low-voltage shore power junction box.
