Effect of synchronization of Marx generators on primary test stand

摘要: 对PTS装置的24台Marx发生器进行了独立调试实验，实验结果表明：在充电电压60 kV、工作欠压比62%条件下，24台Marx发生器的输出电压的时延在245～285 ns的范围内，时延最大差异为40 ns，时延抖动均小于10 ns。通过对PTS装置控制时序和中间储能器充电电压波形的分析，认为Marx发生器输出电压的时延差异在50 ns内，中间储能器上总的电压损失小于1%，对主开关的工作状态基本上没有影响。Abstract: The tests of 24 Marx generators on the primary test stand(PTS) have been carried out. When the charging voltage is 60 kV and the working ratio is 62%， the delay time of output voltage for 24 Marx generatorsranges from 245 to 285 ns with a total spread of 40 ns and individual jitters less than 10 ns. The timing diagram of the PTS control system and the charging waveform of the intermediate storage capacitor are analyzed. When the spread of delay time for output voltage of 24 Marx generators is 50 ns， the voltage loss of intermediate storage capacitor is less than 1% and it has no effect on the operation state of the main switch.
