| 摘 要： | 基于脉冲形成原理提出了一种快脉冲高电压大电流测量探头的在线标定方法。利用闪光二号加速器输出线和二极管作为脉冲形成线,结合研制的低电感开关和负载,产生一个前沿小于3 ns、脉宽20 ns的准方波,对二极管电压测量探头微分型电容分压器和电流测量探头微分环进行了在线标定,得到测量探头在实际使用环境中的时间响应小于4 ns。该方法消除了非在线标定环境和实际环境无法统一对标定结果的影响,可推广应用于传输线型脉冲功率装置的探头标定。

| Abstract: | A calibrating method of high voltage and current probe for fast pulse measurements is presented based on pulse formation principle. A voltage and current generator which used the output line and diode of Flash Ⅱ accelerator as pulse formation line was built with a self-developed low inductance gas switch and load. A quasi-square waveform, with a rise time of about 3 ns and a half width of 20 ns, was measured when the voltage and current on the load are 0.75 kA and 13.5 kV, respectively. The voltage and current probes of diode of flash Ⅱ accelerator were then calibrated, and their time responses were less than 4 ns. The calibrating method can generate a fast pulse for high voltage and current probe calibration in practical circumstance, it can also calibrate the probes of transmission-lin |
