Because the uncontrolled rectifier device is required to be connected with the copper bar, the copper bar can be fixed on the frame through the insulating column, so that the fixation of the copper bar is more stable, and the device is further ensured not to fail due to the breakage of the pins of the copper bar of the uncontrolled rectifier module 200 and the IGBT module 300 in the transportation process; meanwhile, other devices can be fixed by the mounting frame 600, so that severe shaking in the transportation process can be prevented, and influence on internal wiring is avoided.
