<p>A movable shore power variable frequency power supply device comprises an onshore power supply electric box (4), an onboard power receiving system (3) and a variable frequency power supply device (1). The input terminals of the variable frequency power supply device (1) are connected to the onshore power supply electric box (4) via cables, and the output terminals of the variable frequency power supply device (1) are connected to a cable reel box (2) via cables (101). The variable frequency power supply device (1) performs frequency conversion and voltage transformation of an input power supply and then outputs the converted power to the cable reel box (2). The cable reel box (2) is provided with at least one low-voltage reel with a plurality of cables (102) and a plurality of plugs. The cables (102) are connected to the onboard power receiving system (3) via the corresponding plugs. The power supply device performs frequency conversion of the power supply on land and provides vessels in a harbor with the converted power, thus realizes a double-frequency power supply.</p> |
