摘要
根据气体动理论,气体放电理论和电弧等离子体理论,利用能量守恒定律,建立用于35 kV架空配电线路的高速气流灭弧防雷间隙闪络时工频电弧的建弧模型,用MATLAB软件进行计算仿真,分析高速气流的灭弧特性。仿真计算结果表明,高速气流能在0.016 5 s内吹灭工频电弧。
Base on the kinetic theory of gases, model of constructing arc about parallel gap lightning gas discharge theories, arc plasma theories, the protection device with arc-extinguished by highspeed airflow which used in 35kV distribution lines is established by using the energy conservation law, and is simulated and calculated with MATLAB software, the arc extinguishing characteristics of highspeed airflow are analyzed. The results of simulations prove that the power frequency arc is extinguished in 0.016 5 s by high-speed airflow.
