The invention relates to a power transformer pre-excitation system, in particular to a power transformer pre-excitation system of a diving support boat, belonging to the technical field of a pre-excitation system. The power transformer pre-excitation system of the diving support boat is characterized by comprising a main power transformer (1) and a pre-excitation transformer (2), wherein the main power transformer (1) is used for supplying power to a low-voltage load, the pre-excitation transformer (2) is arranged in the main power transformer (1) and connected with a power transformer pre-excitation control unit (3) for controlling a pre-excitation program, and power is supplied to the pre-excitation transformer (2) by a low-voltage end of a deck device transformer .Therefore, power supply switches on a medium-voltage distribution board can be reduced, the length of the medium-voltage distribution board is reduced, the medium-voltage distribution board is convenient to be installed in a distribution board chamber, and meanwhile, the main power transformer is prevented from being incapable of being started by the pre-excitation system.
