Measurement and diagnosis system for 1.2 MV repetitive pulsed power source
摘要
为了更好分析系统的放电特性和工作状态,优化脉冲功率源系统的设计,研制了一套1.2 MV重复频率高功率微波驱动电源测试诊断系统。通过研究高电压、大电流测试技术和数据采集、信号处理、故障诊断技术,同时运用虚拟仪器和电磁兼容等技术,探索开发了一套重复频率脉冲电压电流测试诊断系统。结合系统的研制需求,通过分析各种数据采集设备的优缺点,硬件选用了凌华公司的PXI数据采集系统,软件采用LabVIEW,设计开发了重复频率快信号的采集诊断程序,研制出实时诊断系统,并在1.2 MV重复频率脉冲电源系统中应用,实现了对重复频率电源关键点电压电流的测试以及数据的诊断、处理和远程在线监测,出现故障时报警、存储数据并自动断电等功能。
