摘　　要：为提高移动式变电站快速接入电网能力,研究新型、快速的接地网技术非常必要。针对移动式变电站机动性强、应用场合不确定等特点,提出笼式垂直接地极和柔性石墨水平接地网相结合的接地网方案。实际应用证明该方案是可行的,达到降低接地电阻和提高接地网施工效率的目的。In order to improve the ability of mobile substations to quickly connect to the grid,it is necessary to study new and fast grounding grid technology.Aiming at the characteristics of mobile substations such as strong mobility and uncertain application scenarios,a grounding grid scheme combining cage vertical grounding electrodes and flexible graphite horizontal grounding grids is proposed.The practical application shows that the scheme is feasible,which can reduce the grounding resistance and improve the construction efficiency of grounding grid.
