Description

Ship electrical equipment and its power control method {ELECTRIC EQUIPMENT FOR SHIP AND POWER CONTROL METHOD THEREBY}

The present invention relates to a marine electrical installation, and more particularly to a marine electrical installation and a power control method having a common panel portion for performing a function as a panel for power supply and a panel for power draw in common.

In general, a ship is equipped with a plurality of generators, and power from these generators is supplied to various loads through a breaker installed corresponding to each generator and a main bus common to all generators. . The main bus is normally divided by the disconnecting device, and normally, the disconnecting device is connected to the power supply in the ship, and if any part of the feeding circuit is broken, the disconnecting device is opened to continue feeding only to the good circuit. It works.

Among the various loads on ships connected to the main bus, there is a transverse thruster called a bow thruster.

The bow thruster, also called bow thruster, bow thruster, etc., is located about 1 to 3 meters above the bottom of the ship to enhance the ship's coordination and propel it to the side of the bow. It is a device for. The bow thruster is provided with a propeller installed in the cylinder, and according to the performance of the engine, it is possible to dock and dock by magnetic force without the help of a tugboat, and can also perform a function of rotating the ship 360 degrees in a fixed position.

In addition, an alternative maritime power (AMP), which is a device for feeding power from the land to the ship, is used in connection with the main bus.

As part of various efforts to protect the air and marine environment, AMP is a device that can utilize onshore power to reduce emissions of air pollutants during mooring. Conventionally, ships generate power by using the ship's self-generator during berth, and air emissions are continuously generated. In order to solve this problem, AMP has been developed to use land power.

Therefore, AMP is an onshore power supply facility for receiving the supply of electric power required while the ship is anchored, and can greatly reduce generation of exhaust gas (eg, NOx, SOx, etc.) due to self-power generation in the ship.

The bow thruster and the AMP are connected to the main bus bar, and are fed from the main bus bar or fed through the main bus bar, and usually between the bow thruster and the main bus bar, and the AMP and the main bus bar, respectively, overcurrent or load. Breakers are installed to reduce the damage caused by malfunctions.

1 and 2 schematically show the connection relationship between such a breaker, a feeder panel for installing the breaker, a shore incoming panel for installing the breaker, and a switchboard in which they are installed. In particular, FIG. 1 is a schematic view of a switchboard in which a bow thruster feeding panel and an AMP shore shore incoming panel are installed in a vessel using high voltage, such as a large container ship, and FIG.
