在鞍钢宪法伟大红旗指引下,为了适应轧机生产向优质高产方向发展,几年来,我们对1200可逆冷轧机电气传动控制系统,进行了和正在进行全面的改造,并已见到了一定效果,采用无环流快速可逆可控硅励磁系统的恒电流调节器,就是一例。经过我们的反复实践,大型电机的可逆可控硅励磁系统中所存在的核心问题,如快速的可逆过程,理想的消磁特性及零位振荡得到了理论上和实践上的解决。实践证明,该系统稳 Under the guidance of the Great Red Flag of the Ansteel Constitution, in order to adapt itself to the high-quality and high-yielding mill production, in the past few years, we have carried out and are carrying out an all-round reform on the electrical transmission control system of the 1200 reversing cold rolling mill. We have already seen some results. An example of a constant current regulator without a circulating fast reversible thyristor excitation system. Through our repeated practice, the core problems in the reversible thyristor excitation system of large motors, such as fast reversible process, ideal demagnetization characteristics and zero-point oscillation, have been theoretically and practically solved. Practice has proved that the system is stable
