Description

Technical Field

[0001] The utility model relates to a shore power transfer device, in particular to a mobile shore power transfer device for military ports. Background Art

[0002] During the period when a ship berths at a dock, the dock shore power system is generally used to supply power to it. At present, the rated voltage of the shore power cabinet in the military port dock is 380V, and some shore power cabinets output three-phase four-wire (three live wires and one ground wire), which cannot meet the needs of 220V electrical equipment in daily operations.

[0003] Moreover, a special power connector is installed at the output port of the shore power cabinet. When common equipment without a power connector joint takes power at the dock, the cable head needs to be crimped to the live wiring copper bar inside the shore power cabinet, which not only does not conform to the safe electricity operation procedures but also has a relatively high risk of electric shock.

[0004] Or it is necessary to remove the back panel of the dock shore power cabinet and then crimp the ship's cable to the terminal post to take power. This operation method has the following disadvantages:

[0005] 1. Since the internal power supply of the shore power cabinet cannot be completely disconnected, there is a relatively high risk of electric shock and potential safety hazards for the operators.

[0006] 2. It is impossible to supply power to 380V electrical equipment and 220V electrical equipment simultaneously.

[0007] 3. It cannot be connected to the power connector interface of the dock shore power cabinet and requires targeted modification. Content of the Utility Model
