1. harbour bank electric system peculiar to vessel is characterized in that:

  • it comprises high-pressure frequency-conversion supply unit, high pressrue connection box, high-tension cable volume car and boat-carrying transformer station;

    The high-pressure frequency-conversion supply unit comprises high pressure incoming line cabinet and transformer;

    High-tension cable inserts the high pressure incoming line cabinet and picks out to transformer;

    Described high pressure incoming line cabinet is provided with some grades of current-limiting resistances, and described transformer is connected with frequency converter through high-tension cable, and described frequency converter is made up of through the mode of series connection and parallel connection several pwm power unit;

    Frequency converter is connected with sinusoidal filter through high-tension cable, and sinusoidal filter is connected with the high-voltage terminal cabinet through high-tension cable;

    It also is provided with the PLC Programmable Logic Controller, and described PLC Programmable Logic Controller is connected with frequency converter through holding wire;

    Described high pressrue connection box comprises base;

    Base is provided with the casing of band chamber door, on casing, is provided with double-colored warning lamp, and chamber door is provided with the high pressure door lock;

    Be provided with high voltage indicator in the casing, described high voltage indicator is connected with double-colored warning lamp, high pressure door lock through holding wire;

    Parallel connection is provided with several high-tension terminals on the high-tension cable in the access casing, and it also is provided with the high-voltage plug supporting with high-tension terminal, and high-voltage plug picks out casing through high-tension cable;

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

    That states is provided with louvre on base or casing;

    Described high-tension cable volume car comprises frame;

    On frame, be provided with volume car and cable-remover;

    Described volume car comprises reel and motor, and reel is connected on the main shaft that is fixed in frame, and motor is connected with main shaft with transmission mechanism through magnetic hysteresis shaft coupling, reductor;

    In reel, be provided with high pressure reel current-collector, described cable-remover is located at the front portion of reel;

    Described boat-carrying transformer station comprises high pressure turnover line cabinet, transformer and low pressure turnover line cabinet;

    High-tension cable picks out after inserting high pressure turnover line cabinet;

    Get into transformer, transformer is connected with low pressure turnover line cabinet through low-voltage cable, and low pressure turnover line cabinet is connected with power distribution cabinet through low-voltage cable;

    It also is provided with the PLC Programmable Logic Controller;

    Described PLC Programmable Logic Controller is connected through the circuit breaker of holding wire with low pressure turnover line cabinet, power distribution cabinet respectively;

    The PLC Programmable Logic Controller also is connected with the speed governing lowering or hoisting gear of boat-carrying generator through holding wire, and described boat-carrying generator is connected with power distribution cabinet through holding wire;

    After described high-tension cable inserts the high pressure incoming line cabinet of high-pressure frequency-conversion supply unit;

    Behind high-pressure frequency-conversion supply unit variable-frequency variable-voltage, insert high pressrue connection box;

    Again after high-voltage plug and high-tension cable pick out the casing of high pressrue connection box, the high pressure turnover line cabinet that high-tension cable is gone on board and is connected to boat-carrying transformer station through high-tension cable volume car.
