电阻性本安电路放电特性及模型研究

he paper analyses discharge charateristic of resisitance intrinsically safe circuits,and based on the discharge charateristic of circuit two modles of resistance circuit are built : discharge voltage linear model and discharge current parabolic model. In this paper ,it represents the difference of the two models, and obtains that the discharge current parabolic model is much more accurate than discharge voltage linear model on describing the discharge process. The paper also indicated that the diascharge model of resistance circuit is not only simpled as the discharge model of inductive circuit while the value of L is zero. The analysis of the discharge model of resistance circuit is the basis of researching on complex intrinsically safe circuits, and of great significance on the theoretical study of intrinsically safe circuits.
