大电流晶闸管整流自动升降电流给定的方法

我们在利用大型晶闸管整流设备用于电解化工行业时,我们一般通过输出稳定的直流电流来电解化合物溶液。通常情况下,我们需要操作人员根据实际需求调整直流电流输出值以满足生产和工艺需求。操作人员的手动给定电流值往往速率不平均且伴有误操作的可能性。所以,我们需要自动化设备来代替人工操作以实现最优的运行环境。

Research on the variable speed system of large power alternating current motor

The development status of the variable speed system of large power AC(alternating current)motor drive in China is introduced.The large power AC drive fed by AC-AC converters(cycloconverters)has developed greatly,and some innovations on the theory and engineering technique have been realized.They have been applied to rolling mills,mine hoists,and so on,and remarkable economic and social benefit has been achieved.The development of AC drive fed by large power IGCT(integrated gate commutated thyristors)AC-DC-AC converter is also introduced.It has excellent performance and reliable operation,and has been used in traction.
