Abstract
The present invention discloses a power supply semi-trailer for electric drive fracturing equipment, including a combination of a gas turbine engine, a generator and a rectifying unit, the generator outputs a winding configuration and a voltage required for the rectifying units directly to obviate conventional rectifier transformer equipment. The rectifying unit is connected to the inversion unit through a common DC bus, so that the common DC bus can separately drive multiple inversion units, thus decreasing the wirings of power supply lines. A high voltage inversion unit is disposed on a gooseneck of the electric drive semi-trailer to optimize the spatial arrangement of equipment. The entire power supply equipment has a compact structure, occupies a small area, and is simple in wiring.
