摘要
从直流电路模型的微分方程出发,分析了直流电弧的熄灭原理,给出了利用Runge-Kutta法求解该方程的程序框图,并且结合实际应用研究了燃弧时间的主要影响因素及其影响过程。结果分析表明,利用该研究结果能使电弧可靠、快速地熄灭,为直流开关电器的设计与应用提供了一定的理论指导。
Starting from the differential equation of DC circuit model, this paper analyzed the quenched principle of DC arc and put forward the program chart of solving this equation by using the Runge-Kutta method. Finally, combined with practical application, this paper studied the main influencing factors and their influencing process of arcing time. The result shows that the arc can be quenched reliably and quickly by using the study results, which provides some theoretical guidance for the design and application of DC switching device.
