PRACTICAL CAPACITY ADJUSTMENT CALCULATION FOR AVOIDING HARMONIC DAMAGE IN HIGH-VOLTAGE COMPENSATION DEVICE OF SUBMERGED ARC FURNACE
This article combines the two dimensions of capacitor closing inrush current suppression and harmonic con-trol,and introduces the calculation method of high-voltage compensation devices to adapt to changes in the usage envi-ronment and avoid harmonic damage to capacitors during capacity adjustment.Taking the high-voltage compensation of the submerged arc furnace as an example,a reasonable design concept is proposed for the compensation capacity to en-sure the safe operation of the device in actual industrial environment.
