摘要
煤矿输电线路易遭受雷击的主要原因是雷电活动的随机性和所处环境的复杂性,一般较难确定雷击故障类型,使得防雷措施针对性不强,无法对变电站以及架空线路进行有效保护。文章通过ATP-EMTP建立某煤矿35k V线路模型,对进线段雷电侵入波进行仿真研究,通过对比得出一种合理使用线路避雷器的方法。
Due to the randomness of lightning activities and the complex environment of coal mine, the 35kV overhead transmission lines are easily struck by lightning, and it is difficult to determine the type of fault caused by lightning.Therefore, the lightning protection measures cannot be well-targeted, and substations and overhead lines are not effectively protected.The paper establishes the 35 kV level transmission line model in a coal mine using ATP-EMTP.The lightning invasion wave is simulated, and the rational usage of line surge arrester is given.
