摘　　要：研究了放电回路参数对氙灯快速放电特性的影响，用计算机进行了放电电流的模拟运算，并用试验的方法对氙灯高压快速放电特性进行了研究。为了延长氙灯寿命，采用了预燃技术，为了减小氙灯初始放电电感，加快放电脉冲上升时间，采用了预脉冲技术。预燃电流１００ｍＡ预脉冲电流１０～２０Ａ，脉宽１５０ｓ，储能电容Ｃ＝０．４７Ｆ，工作电压４～１８ｋＶ，放电脉宽３．５ｓ，加预脉冲后为３．０ｓ。It is described that the influence of the circuit parameters on the discharging performance of the xenon flashlamp. The analogy approach is made by means of the computer , and the fast pulse dis- charge of the Xe lamp at high voltage is studied in experiment. To increase the lamp lifetime . a sim- mering mode of triggering is adopted .and to decrease the self - inductance of the lamp . namely decrease the risetime ) . a pre - pulsed discharge is employed. In the experiment , the simmer current 1 00 mA flows through the lamp .the pre - pulse energy is 2. 4 J , the pre-pulse duration is 150 s,and peak current is 10 ～ 20A. The energy storage capacitor of 0. 47 F is chosen,the main voltage 4～18 kV,resulting in a current pulse duration of 3. 5s without pre - pulse and 3. 0 s with pre - pulse.
