1. a Wharf marine shore power system, it is characterized in that:

  • it comprises high-voltage variable frequency power source device, high pressrue connection box, high voltage cable reel and ship-borne transformer substation;

    The high-voltage variable frequency power source device comprises High-voltage Incoming Cabinet and transformer, high-tension cable access High-voltage Incoming Cabinet also picks out to transformer, described High-voltage Incoming Cabinet is provided with some grades of current-limiting resistances, described transformer is connected with frequency converter by high-tension cable, described frequency converter is comprised of by series connection and mode in parallel several pwm power unit, frequency converter is connected with sinusoidal filter by high-tension cable, and sinusoidal filter is connected with the high-voltage terminal cabinet by high-tension cable;

    This high-voltage variable frequency power source device also is provided with the PLC Programmable Logic Controller, and described PLC Programmable Logic Controller is connected with frequency converter by holding wire;

    Described high pressrue connection box comprises base, base is provided with the casing with chamber door, is provided with double-colored warning lamp on casing, and chamber door is provided with the high pressure door lock, be provided with high voltage indicator in casing, described high voltage indicator is connected with double-colored warning lamp, high pressure door lock by holding wire;

    On high-tension cable in the access casing, parallel connection is provided with several high-tension terminals, and described high pressrue connection box also is provided with the high-voltage plug supporting with high-tension terminal, and high-voltage plug picks out casing by high-tension cable;

    Described high voltage indicator is connected on high-tension cable by high pressure sensor;

    Be provided with louvre on base or casing;

    Described high voltage cable reel comprises frame, be provided with volume car and cable-remover on frame, described volume car comprises reel and motor, reel is connected on the main shaft that is fixed in frame, motor is connected with main shaft with transmission mechanism by magnetic hysteresis shaft coupling, reductor, be provided with high pressure reel current-collector in reel, described cable-remover is located at the front portion of reel;

    Described ship-borne transformer substation comprises high pressure line cabinet, transformer and low pressure line cabinet, after high-tension cable access high pressure line cabinet, pick out, enter transformer, transformer is connected with low pressure line cabinet by low-voltage cable, and low pressure line cabinet is connected with power distribution cabinet by low-voltage cable;

    Described ship-borne transformer substation also is provided with the PLC Programmable Logic Controller, described PLC Programmable Logic Controller is connected with the circuit breaker of low pressure line cabinet, power distribution cabinet by holding wire respectively, the PLC Programmable Logic Controller also is connected with the speed-regulation lifting device of boat-carrying generator by holding wire, and described boat-carrying generator is connected with power distribution cabinet by holding wire;

    After the High-voltage Incoming Cabinet of described high-tension cable access high-voltage variable frequency power source device, access high pressrue connection box after high-voltage variable frequency power source device variable-frequency variable-voltage, again after high-voltage plug and high-tension cable pick out the casing of high pressrue connection box, the high pressure line cabinet that high-tension cable is gone on board and is connected to ship-borne transformer substation through high voltage cable reel.
