The invention relates to low-voltage hybrid reactive compensation complete equipment and a use method thereof, and belongs to the technical field of reactive compensation equipment. The technical scheme is characterized in that the complete equipment comprises a power quality detection meter (3), an intelligent low-voltage oil immersion capacitor (4), a controller (5) and a low-voltage APF (6). The power quality detection meter (3) is connected with the intelligent low-voltage oil immersion capacitor (4) mutually; the controller (5) is connected with the intelligent low-voltage oil immersion capacitor (4) and the low-voltage APF (6); the controller (5) and the low-voltage APF (6) are respectively provided with a power detection unit; and the controller (5) is provided with an automatic mode structure (51) and a manual mode structure (52). The beneficial effects are that the controller can control the intelligent low-voltage oil immersion capacitor and the low-voltage APF (active power filter) in a centralized control manner; and optimal combination of performance features of the intelligent low-voltage oil immersion capacitor and the low-voltage APF is achieved to reach an intelligent reactive compensation result.
