AI Technical Summary
Existing parallel hybrid active power filters suffer from reduced heat dissipation and reduced lifespan due to the integration of multiple devices into a single module.
By designing an adjustable base plate structure, the spacing between the base plates can be adjusted using a combination of rotating shafts, rotating rods, round rods, and sliding grooves, thereby improving heat dissipation. The height of the base plates is fixed by fixing bolts to prevent shaking and falling.
This improves the heat dissipation of the active power filter, extends its service life, and ensures stable installation, preventing shaking and falling.
