基于Simplorer的非爆炸性本安电路仿真方法研究

Study on Assessment of intrinsically safe with circuit emulation method based on Simplorer

提出一种通过数值计算对本安电路进行非爆炸性评价的方法。使用电路仿真软件Simplorer对基本电路进行仿真,将放电火花看作是非线性时变电阻,从而计算其放电功率、能量等参数,并以此参数作为本安评价的标准。仿真结果较为准确,且容易推广到复杂电路,对电路本安设计具有一定的指导作用。

Proposed a non - explosion assessing method for intrinsic safety circuit by numerical calculation. Using circuit simulation software Simplorer to simulate basic circuit, and regarding spark discharge as nonlinear time -varying resistance, we can calculate spark power, energy and other parameters. These parameters can regard as a standard of the intrinsic safety circuit evaluation. Simulation result is accurate, and it is easy to promotion to complex circuit. This way can guidance intrinsic safety circuit design.
