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] At present, the rated voltage of the shore power cabinet at the military port terminal is 380V. Some shore power cabinets output three-phase four-wire (three live wires and one ground wire), which cannot meet the demand of 220V electrical equipment in daily operations; some shore power cabinets output three-phase five-wire (three live wires, one ground wire and one neutral wire). At this time, when using the neutral wire, it is necessary to connect the wire separately on the neutral busbar, which has potential safety hazards.

[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 terminal, 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 regulations but also has a high risk of electric shock.

[0046] When powering a 220V electrical device, transfer switch cabinet 1 and conversion switch cabinet 25 are used in combination. First, crimp the power cable head of the electrical device to the red terminal 33 and black terminal 34 of conversion switch cabinet 25, and connect conversion switch cabinet 25 to the 380V terminal 15 of transfer switch cabinet 1 through the second quick electrical connector assembly 36. Second, connect the male head of the first quick electrical connector assembly 35 to the female head 8 of the first quick electrical connector, and then connect the special power connector of the male head of the first quick electrical connector assembly 35 to the onshore power cabinet interface at the dock. Finally, turn on the second leakage circuit breaker 32, and at this time, power is supplied to the 220V electrical device. For devices with a power consumption current of less than 10A, the power plug can be directly inserted into the second inclined five-hole socket 28; for devices with a power consumption current of 16A, the plug is inserted into the second three-hole socket 27 to directly obtain power.

[0047] When supplying 380V power to a device without a power connector joint, only transfer switch cabinet 1 is used. First, crimp the power cable head of the 380V electrical device to the 380V terminal 15 of transfer switch cabinet 1. Second, connect the male head of the first quick electrical connector assembly 35 to the female head 8 of the first quick electrical connector, and then connect the special power connector of the male head of the first quick electrical connector assembly 35 to the onshore power cabinet interface at the dock.

[0049] When powering a 220V electrical device, first connect the neutral wire to the neutral terminal 12 of transfer switch cabinet 1. Second, crimp the power cable head of the 220V electrical device to the 220V terminal 14 of transfer switch cabinet 1, or directly insert the power plug into the matching second three-hole socket 27 and second inclined five-hole socket 28.
