摘要
在火花试验装置上进行爆炸试验,得到本质安全复合电路的放电波形,发现电弧电压基本维持在最小建弧电压,而电容电流随着电路参数的不同而发生振荡.发生电流振荡的条件是电感时间常数大于电容时间常数的一半.建立了容性点燃时的电弧放电数学模型,并进行了仿真.
Arc discharge waveforms were obtained with spark-test apparatus.It was found that when the capacitive ignition occurred, arc voltage will keep minimum arcing voltage, but arc current possibly attenuates in sinusoidal form with different circuit parameters.The condition of occurring current oscillation is that inductive time constant is the greater than the half of the capacitive time constant.The mathematical model of arc discharge for capacitive ignition was established and simulation was made.
