摘要
为解决电力系统中输电线路跳闸和断线难题,提出一种高速气流灭弧防雷装置。介绍了该装置的运行原理,建立了强气流下耦合电弧的数学模型,通过COMSOL Multiphysics仿真软件仿真气流和电弧耦合过程。仿真结果显示,灭弧效果取决于气流速度的大小,随着气流速度的增大,熄灭电弧的效果更明显。
In order to solve the problem of trip and break of transmission line in power system,And high-speed airflow arc extinguishing lightning protection device is proposed.In this paper,the operation principle of the device is introduced in detail,and the mathematical model of coupled arc under strong gas flow is established.The process of air flow and arc coupling is simulated by COMSOL Multiphysics simulation software.The simulation results show is that the effect of arc extinguishing depends on the gas velocity,and the effect of arc extinguishing is more obvious with the increase of gas velocity.
