The utility model provides a device body arrangement structure of a single-
machine 48-pulse
hydrogen production
rectifier transformer, the single-
machine 48-pulse
hydrogen production
rectifier transformer comprises a left device body and a right device body, and high-
voltage winding D connection, low-
voltage winding d connection and low-
voltage winding y connection of the left device body and the right device body are all combined into 24 pulses. The
phase angle difference of the 24-pulse
rectifier transformers of the left
transformer body and the right transformer body is equivalent to 48 pulses in a 7.5-degree combination mode, each 24-pulse rectifier transformer is a shared three-column three-phase iron core, and a conjugate iron core with the 15-degree
phase difference of a high-voltage winding is arranged between the upper portion and the lower portion of the three-column three-phase iron core. A channel is provided for
phase difference excitation between the upper high-voltage winding of the three-column three-phase iron core and the lower high-voltage winding of the three-column three-phase iron core through the conjugate iron core, four rectifiers with 12 pulses and 15-degree
phase difference can be dragged by the valve side of the single-
machine 48-pulse rectifier transformer, and the one-to-four function can be effectively achieved; meanwhile, the size and the weight of the
system are effectively reduced, the overall manufacturing cost is greatly reduced, and rapid industrialization of green
hydrogen is facilitated.
