双机拖动直缝焊管机组SCR-DDC变流装置的应用

APPLICATIONS OF SCR-DDC CURRENT CONVERTING DEVICES TO A PIPE LONGITUDINAL-WELDING MILL USING 2 CONVERTERS

实际使用证明,采用单板机对SCR进行控制,线路简单,调节方便,精度高,工作稳定可靠。

Practice shows that SCR can be controlled by a single-chip computer, which is of simple circuit, convenient regulation, high precision and steady and reliable operation.
