摘　　要：通过分析复合型本质安全型电路的原理,得出了在振荡和非振荡两种情况下放电电流、放电功率及放电能量的数学模型,并利用Matlab软件仿真出电感、电容对电路放电特性的影响图。结果表明:随着电感的增加,放电电流变化相对平缓且其达到最大值的时间较长;放电功率和放电能量均随电感的减小而增大。随着电容的增加,放电电流的曲线变化相对比较大;在同一时刻,放电功率和放电能量均随电容的增大而增大。The mathematical models of discharge current,discharge power and discharge energy in oscillating and non-oscillating circumstances were obtained by analyzing the principle of compound intrinsically safe circuit,and the influence of inductance and capacitance on the discharge characteristics of the circuit were simulated by Matlab software.The results showed that with the increase of inductance,the change of discharge current was relatively gentle and the time of reaching the maximum value was longer,the discharge power and discharge energy increase with the decrease of inductance.With the increase of capacitance,the curve change of discharge current was relatively large.At the same time,the discharge power and discharge energy increased with the increase of capacitance.
