摘　　要：在两级电点火装置上，利用高压脉冲电源进行了ＨＡＮ基液体发射药的电点火实验。实验观测到：在液体发射药的可靠点火过程中，存在着无电弧与电弧两种放电方式。实验研究了实现无电弧点火、限制电弧放电所需的电源特性参数及点火结构参数。目前电能利用率保持在６０％以上，而电弧放电能量仅占负载所吸收总电能的３０％。这种电点火系统对于提高武器自动化程度、增加射速等均具有重要的实际意义。A high current/voltage pulse source is used in two-stage electric igniter to transfer the electrical energy to the electrodes. LP1846 in the precombustion chamber is initiated by discharging a high current pulse between a pair of coaxial electrodes,antechamber containes an additional LP booster charge. For the complete ignition of LP 1846,arcless discharge and arc discharge occur in different phases of ignition. In order to initiate the LP without arc formation,effects and coupling of electric pulse characteristics, ignition configuration parameters on LP ignition property are investigated. In these tests,the electrical energy to the electrodes is maintained over 60 percent of the stored energy of the capacitor,and the arc discharge energy is 30 percent of the electrical energy to the electrodes. This kind of LP ignition system is of practical for improvement of LPG performances.
