摘　　要：对于本质安全电路,如果电路中含有有源阻抗变换电路,在判断电路的本质安全性能时,不仅要考虑实体电感和实体电容的作用,还要考核模拟电感和模拟电容的影响。该文在分析模拟电感和模拟电容的基本原理和端口特性的基础上,通过分别计算实体储能元件和模拟储能元件的能量,对其“潜在”的危险性进行了量化和分级。并在此基础上,从本安电路的防爆安全性出发,利用评定本质安全电路安全性的参考曲线和数据,建立模拟电感和模拟电容电路本质安全性能评价判据,以达到正确评估模拟元件对本安电路防爆安全性影响的目的。For intrinsically safe circuits,if the circuit contains an active impedance conversion circuit,when judging the intrinsic safety performance of the circuit,not only the effect of physical inductance and physical capacitance,but also the affect of simulated inductance and simulated capacitance must be considered.Based on the analysis of the rationale of the simulated inductors and the simulated capacitors,this paper quantified and classified their"potential"hazards by calculating the energy of physical energy storage components and simulated energy storage components respectively.And on this basis,this paper used the reference curves and the data for evaluating the safety of intrinsically safe circuits,starting from the perspective of explosion-proof safety of intrinsically safe circuits.The intrinsic safety evaluation criteria of analog inductance and analog capacitor circuits are established,so as to achieve the purpose of correctly evaluating the impact of analog energy storage components on the explosion-proof safety of the intrinsically safety circuits.
