摘要
通过对低压断路器实验数据进行分析,在matlab中利用最小二乘法计算出Mayr电弧模型的相关参数,并利用Simulink建立简化的低压断路器开断短路电流的模型。仿真所得的结果与实验数据相比较接近,表明该方法对低压断路器开断动作的定性分析有一定参考价值。
By the analysis of the experimental data of a low voltage circuit breaker, use leastsquare method to calculate the relevant parameters of Mayr are model in Matlab. And use Simulink to establish a simplified breaking short-circuit current model of the low voltage circuit breaker. The simulation results are close with the experimental data. It shows that the method has a certain referenee value to the qualitative analysis of the breaker breakig action.
