Air-cooled high-voltage dynamic reactive power compensation device power unit

The utility model relates to a power unit of an air-cooled high-voltage dynamic reactive power compensation device. The power unit comprises a protection box. According to the air-cooled high-voltage dynamic reactive power compensation device power unit, an external power supply is electrically connected with a double-shaft motor, then the double-shaft motor operates to drive second conical teeth installed on the outer sides of two transmission shafts to rotate at the top of a first conical tooth, and the second conical teeth are installed at the top of the first conical tooth in a meshed mode; therefore, the second conical teeth drive the first conical teeth, the rotating rods and fan blades installed at the tops of the two rotating rods to rotate to generate airflow which is blown to the power module assembly, so that the efficient air-cooling heat dissipation effect is achieved, and the effect of conveniently guiding hot air generated by blowing the power module assembly to the outside is achieved through
