Background
Hongsan Industrial Park is a professional functional zone characterized by rubber industry, and the electric loads are mainly rubber cutters, open mills and internal mixers. The electric power consumption of the motor in the internal mixer system accounts for about 70% of the total electric power consumption in the rubber industry. Because of the high power of the internal mixer and the rapid change of the non-linear interference load, a large number of harmonics are generated during its use, which is harmful to the whole power system. On-site, one capacitor cabinet failed to catch fire, and the capacitor in the other capacitor cabinet was bulging.
Power Quality Problems
The on-site voltage is high, and the harmonic current content is also high, mainly the 5th, 7th, 11th and 13th harmonics, of which the 5th harmonic has exceeded the national standard. At the same time, when the power capacitor is over-voltage and over-current, it is easy to cause the thermal aging reaction of the internal insulation, and the insulation expands or the decomposition volume of the insulation becomes larger, which leads to the bulging phenomenon of the power capacitor. In order to avoid the failure of on-site capacitor cabinet again and make normal reactive power compensation, an active power filter device is added in the power system for harmonic control and harmonic control.
Power Quality Solutions
Generally speaking, after the installation of YTPQC Active Power Filter (APF), the power quality meets the requirements of China National Standard. Make the equipment in the whole plant area free from the pollution hazard of harmonic voltage.
