[0039] The actual operation procedure for this embodiment is as follows:

[0040] When the vehicle-mounted naval port mobile shore power conversion device disclosed in this embodiment supplies power to an external electrical device with a power connector plug, it inserts its power connector plug into the ship / shore dedicated connector socket 20 on the panel assembly 11, and then sets the power supply voltage through the 380V / 127V conversion switch 19 and closes the first circuit breaker 16 to supply power to the electrical device.

[0041] When the vehicle-mounted military port mobile shore power conversion device disclosed in this embodiment supplies power to 380V electrical equipment without a power connector, firstly, the power cable head of the electrical equipment is crimped to the 380V terminal 29 and the second protective ground terminal 30 of this embodiment. Secondly, the second circuit breaker 31 corresponding to the 380V terminal 29 is opened. Finally, when the second power supply indicator 32 is lit, power supply to the electrical equipment begins.

[0042] When the vehicle-mounted military port mobile shore power conversion device disclosed in this embodiment supplies power to a 220V electrical device without a power connector, firstly, the power cable head of the electrical device is crimped to the 220V terminal 22 and the first protective ground terminal 24 of this embodiment. Secondly, the leakage circuit breaker 25 corresponding to the 220V terminal 22 is turned on. Finally, when the first power supply indicator light 28 is lit, power supply to the electrical device begins. It should be noted that for electrical devices with a current consumption of less than 10A and a standard plug, the power plug can be directly inserted into the five-hole socket 23, and then the corresponding leakage circuit breaker 25 is turned on. When the first power supply indicator light 28 is lit, power supply to the electrical device begins.

[0043] This embodiment also supports the use of a portable shore power adapter 36.

[0044] This application discloses a vehicle-mounted mobile shore power conversion device for military ports. Through component integration and structured design, it can output 380V, 220V, and 127V voltages. It can collect and record electrical energy data such as voltage, current, frequency, power, and power factor during the power supply process, display the power consumption, frequency, current, and voltage, and print the power consumption settlement data. It also solves the problem that traditional three-phase four-wire shore power cabinets at docks cannot provide 220V power. The overall structure and functions of this application have a very high degree of integration, proper protection settings, convenient operation, and safety and reliability. The main feature is that the device is completely de-energized before being connected to the shore power cabinet, and there is no risk of electric shock during all wiring operations. It is highly mobile and can quickly reach the deployment location, adapting to all-weather shore power transfer and support.

[0045] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
