基于PSpice的电爆丝断路开关数值仿真

电爆丝断路开关是在电感储能系统中广泛应用的断路开关,其具有结构简单、成本低、截断能力强的特点。介绍了电爆丝工作的基本原理,其本质为一个快速增长的电阻,利用高阻抗来实现断流。通过PSpice软件建立了电流通过电爆丝断路开关工作时,其电阻变化的模型,从而可以仿真电爆丝断路开关的工作过程。设计了一组电爆丝断路开关的实验,PSpice模型仿真结果同实验结果进行了比较。结果发现,该模型起爆时刻,产生电压幅值等方面和实验结果比较接近,说明该模型比较科学合理,对以后的电爆丝断路开关的设计具有较大的参考价值。分析了产生误差的原因及该种仿真方法的局限性。

Abstract

Electric exploding opening switch(EEOS) is widely used in the inductive energy storage system, which has the features of simple structure, low cost, and strong ability of cutoff. Firstly the process of electric exploding wire was introduced. Its essence is a rapidly increased resistance, using its high impedance to achieve cutoff. Then a PSpice model, which simulated the resistor of the electric exploding opening switch, was created. A set of electric exploding opening switch experiments were designed. After that, the PSpice model simulation results were compared with the experimental results. The exploding moment and the voltage of the model were relatively close to the experimental results. The result shows that the model is reasonable. Finally, the deviation and limitation of this method were analyzed.
