直流炉是高效节能的新型用电设备、安装数量日渐增多。但伴随其而来的另一方面是对电网造成谐波污染和降低电网的功率因数。因此，有必要根据具体设备的运行参数，设计安装性能合理的滤波器。该文涉及某厂一套典型滤波器的设计思路。这套滤波器自１９９５年４月投运以来，对１１次谐波吸收达８０％ＶＸＭ，对１３次谐波吸收达５５％以上，有效地改善了母线电压波形，３５ｋＶ母线上各次谐波均已达到国家标准，功率因数补偿达到０．９５以上，并充分达到了预期的节能目的。
DC furnace is a new energy-efficient electrical equipment, increasing the number of installations. But the other side that comes along is to cause the harmonic pollution to the electric wire netting and reduce the power factor of the electric wire netting. Therefore, it is necessary to design and install the filter with reasonable performance according to the operating parameters of the specific equipment. This article relates to a factory a set of typical filter design ideas. Since this filter was put into operation in April 1995, the harmonic absorption of the 11th harmonic reaches 80% VXM and the harmonic absorption of the 13th harmonic reaches more than 55%, which effectively improves the bus voltage waveform and the harmonics on the 35kV busbar Have reached the national standard, power factor compensation reached more than 0.95, and fully meet the expected energy-saving purposes.
