介绍了一种基于PLC技术的OCS系统在复合波发生器控制系统中的应用。通过对CWG的控制系统输入输出量进行PLC编程,可以使CWG产生符合IEC规定的1.2/50μs浪涌电压和8/20μs浪涌电流,对SPD(低压防雷器)等进行检测试验。在PLC控制程序中实现了通过人机界面对控制参数进行编辑,并以全新的相位触发控制方式触发浪涌。
An application of OCS system based on PLC technology in compound wave generator control system is introduced. Through PLC programming of CWG control system input and output, the CWG can produce 1.2 / 50μs surge voltage and 8 / 20μs inrush current according to IEC, and test the SPD (low-voltage lightning arrester) and so on. In the PLC control program to achieve through the man-machine interface to edit the control parameters, and a new phase trigger control trigger surge.
