The special box for new energy power generation is a high-voltage/low-voltage preassembled substation (hereinafter referred to as substation) integrating high-voltage switchgear, transformer body, protective fuse in the fuel tank, and low-voltage switchgear and corresponding auxiliary equipment. It is a new energy grid-connected inverter (or alternator) voltage after the boost transformer rises to 10KV or 35kV, through the 10kV or 35kV line upward output of electric energy connected to the grid special booster equipment, is the ideal supporting equipment for new energy power generation system.
