Low-voltage SVG (static var generator) and APF (active power filter) module serialized modularized structure based on capacity specification

The invention discloses a serialized modularized structure of low-voltage SVG and APF modules based on capacity specifications. The serialized modularized structure comprises a case assembly, an intelligent measurement and control assembly, a reactance assembly, a composite IGBT assembly, a composite IGBT driving assembly, an information sampling assembly and a capacitor assembly. The front plate, the rear panel, the left side plate and the right side plate are welded to form a machine frame, and a middle plate is arranged in the machine frame and divides the machine frame into an upper cavity and a lower cavity up and down; an intelligent box is arranged on the side, close to the front plate, in the lower cavity of the machine frame, and an intelligent measurement and control assembly is arranged in the intelligent box. The reactance assembly is arranged on the rear side of the upper cavity of the machine frame; the composite IGBT assembly is arranged on the front side in the upper cavity of the machine fram
