ELECTRIC MOTOR CONTROL BOARD BUILT-IN ZERO HARMONIC FILTER EQUIPPED FUNCTION OF SAVING POWER AND REACTOR MONITORING MODULE

摘要

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a motor control panel, and more particularly, to a motor control panel having a power-saving type harmonic filter and a reactor protection module. The motor controller having the power saving type harmonic filter and the reactor protection module according to an embodiment of the present invention includes a filtering unit for filtering an image harmonic filter, and a control unit for controlling the image harmonics filter and the reactor protection module on the R, S and T phase power lines for supplying power to the image harmonic filter and the motor And a first switching control unit for connecting the image harmonic filter to a power supply line on the R, S, and T phases for supplying power to the motor by turning on the switching unit in synchronization with the driving of the motor An image harmonic filter module including; And a reactor protection module that performs a protection operation of a capacitor protection reactor that blocks an overcurrent flowing into a capacitor provided in parallel to a line that supplies power to the motor.
