中文摘要: 使用冲击电流发生器,通过埋设接地网,采用现场试验研究了不同注入电流的波前时间、不同注入点情况下接地网的冲击特性.结果表明,接地网的脉冲泄流效果与脉冲电流的波前时间、注入点密切相关.脉冲电流从接地网的中心注入可有效降低接地点的电位,提高接地网的脉冲泄流效果.
Abstract:An impulse current generator is used through burying grounding grid to investigate the impulse characteristics with different rise time of injected current,different injection point of grounding grid by the use of field experiments.The results show that impulsive discharging efficiency is closely related to the rise time of injected current and the injection point.Impulse current injected from the grounding grid center,which can effectively reduce the potential of ground point,improves the impulsive discharging efficiency of the grounding grid.
