摘要
电感性本质安全电路的放电电流线性衰减模型以放电时间为参数,该参数是电路参数的隐函数.通过分析电弧放电实际过程,引入最小建弧电压,放电时间不但可由电路参数直接表示出来,而且得出放电时间与电感和稳定电流的乘积成正比的结论.此外,进一步应用能量法建立了评价电感电路本质安全性能的判别式,对设计人员预估电路本安性能提供一定帮助.
Current linear attenuation model of inductive intrinsically safe circuits is based on the parameter for discharge time which is implicit function of circuit parameters. After analyzing actural discharge process,minimum arcing voltage is introduced, discharge time can be expressed by circuit parameters, the conclusion is obtained that discharge time is in proportion to the product of inductance and stable current. Furthermore the intrinsic safety discriminant of inductive circuits is established which can help designers to pre evaluation intrinsic safety of circuits.
