指出电感性本质安全电路的电流线性衰减模型与实际情况不符，也不能准确说明放电能量的误差．在实验研究的基础上，得出了电弧放电的动态伏安特性服从直线规律的结论，并由此建立了以电弧电压初始值和终止值为参数的数学模型，这不但能克服线性模型的上述缺点，而且还通过将电弧看作一非线性电阻，提出了应用非爆炸方法来评价电路本安性能的新思路
It is pointed out that the current linear attenuation model of inductive intrinsically safe circuit does not accord with the actual situation and it can not accurately explain the error of discharge energy. Based on the experimental study, the conclusion is drawn that the dynamic voltammetry of arc discharge obeys the law of linearity, and the mathematical model which takes the initial value of arc voltage and the final value as the parameter can not only overcome the above mentioned linear model But also think of the arc as a nonlinear resistor and put forward a new idea of using the non-explosive method to evaluate the intrinsic safety of the circuit
