未来一定会有更高电压、更大电流的新型功率器件出现,这将会提高变频器的单机容量。热连轧是黑色冶金行业的一个重要工艺生产线,随着人们对产品质量需求越来越高,其工艺或机械装备都要求电气传动设备采用高性能的调速装置作为支撑。在实际工程中,受成本、设计经验等多方面因素的影响,热轧生产线所使用的变频器的谈判、设计、选型和应用等方面还有许多实际问题需要探讨。为了对常规热连轧变频器的设计选型及应用有更多的了解,本刊记者特别
The future there will be higher voltage, higher current new power devices appear, which will improve the stand-alone inverter capacity. Hot tandem rolling is an important production line of the black metallurgy industry. As the demand for product quality is getting higher and higher, the technology or mechanical equipment requires the electric transmission equipment to adopt the high-performance speed governor as the support. In the actual project, due to the influence of many factors such as cost and design experience, there are still many practical problems that need to be discussed in the negotiation, design, selection and application of the inverter used in the hot rolling production line. In order to conventional hot rolling converter design selection and application of more understanding, the reporter in particular
