摘　　要：针对真空器件的老化锻炼需要,设计了基于PLC控制的正负200 k V高压脉冲发生器装置。系统采用工业PLC和工控计算机结合的方式,实现对直流高压充电电源的数字控制、氢闸流管触发脉冲的时间控制、极性转换高压继电器的转换控制、限流电阻的调节控制。利用高性能示波器的数据获取功能,通过USB接口实时获取高压脉冲的电压、电流、波形及时间信息,基于WINCC V6.2设计了良好的人机交互界面,实现了真空器件击穿的智能判断和检测,也可以在自动状态下实现器件的各种流程的老化锻炼。系统采用PLC控制,使其在大脉冲放电的恶劣环境下能可靠长期稳定地工作。Aiming at the aging test requirements of the vacuum components, a HV pulse generation system based on the PLC control is designed. It consist of industry PLC and industry computer, digital controls are implemented to the direct current charge supply, time control to the hydrogen thyratron, and switch control to polarity conversion relay and current limiter. Using the digital oscilloscope, it acquires the HV pulse waveform information of voltage, current and time. It has the nice interface of human - computer interaction based on the WINCC V6.2 Software. It can judge and test the breakdown of the vacuum components, and run the different aging processes in automatic condition. Because of using PLC, the system can work stably, dependably and for a long -term at the severe circumstances.
