DISTRIBUTION BOARD SMART COMPENSATION APPARATUS CAPABLE OF IMPROVING POWER-FACTOR OF LEADING PHASE AND LAGGING PHASE CURRENT

摘要

Switchgear equipped with a smart automatic power factor correction device according to the present invention, a plurality of capacitor banks are connected in parallel to the power line to the load to compensate for the ground reactive power, selectively connected to the power line by the first switch unit (C1, C2, C3); At least one reactor bank (L1) connected in parallel to a power line going to the load to compensate for advance reactive power, and selectively connected to the power line by a second switch unit; An automatic power factor controller 10 determining a required compensation capacity using the current and voltage sensed by the power line and controlling the first switch unit and the second switch unit; It is characterized in that to be able to compensate for both.
