| Abstract: | Base on the kinetic theory of gases,gas discharge theories,arc plasma theories,the model of constructing arc about parallel gap lightning protection device with arc-extinguished by high-speed 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 high-speed airflow are analyzed.The results of simulations prove that the power frequency arc is extinguished in 0.0165 s by high-speed airflow. |
