轧钢机直流供电设备运行中引起的电源波型畸变,造成电器设备损坏频繁和轧制过程的失稳失控,是轧钢生产技术中迫切需要解决的问题。采用高次谐波吸收技术,可以降低电网污染,提高供电装备的可靠性和自动控制的稳定性,是轧钢生产向“高速、自动,连续”发展的重要技术环节。上钢十厂“静态型高次谐波吸收装置”在设计中采用了计算机辅助设计技术(CAD),从工厂现场谐波情况出发,选用了5、7、11次吸收回路,取消了吸收回路无感电阻的使
Rolling mill DC power supply equipment operation caused by the power waveform distortion, resulting in frequent damage to electrical equipment and rolling process out of control, is an urgent need to solve the rolling steel production technology issues. The use of higher harmonic absorption technology can reduce the pollution of the power grid, improve the reliability of power supply equipment and the stability of automatic control. It is an important technical link in the development of “high speed, automatic and continuous” rolling production. In the design of “static type high-order harmonic absorption device” of No.10 Steel Plant, CAD (Computer Aided Design Technology) was adopted in the design. Based on the harmonic situation in the factory, 5, 7 and 11 absorption circuits were selected, and the absorption circuit was canceled No sense of resistance so
