根据有关文献和标准资料,对间隔距离这一防雷措施进行了深入研究,明确阐述了间隔距离的概念、作用、组成形式、计算方法和检查要点。发现新版GB50057—2010《建筑物防雷设计规范》对于间隔距离问题表述尚存在一定不足,尤其是对于防止第二类、第三类防雷建筑物接闪器对附近金属物或电气和电子系统线路的反击所应满足的间隔距离要求尚不够到位,对此提出了GB50057—2010相关条款的修改建议,供有关方面参考。间隔距离问题不断引起有关方面的重视,国外有不少学者[1-4]对于间隔距离问题进行了较多的研究,国内对于间隔距离的研究文献相对比较少。
According to the relevant literature and standard data, the distance between the lightning protection measures were studied in depth, clearly describes the concept of interval distance, role, composition, calculation methods and check points. Found that the new version of GB50057-2010 “Lightning Protection Design Code” for the separation distance problems still exist some deficiencies, especially for the second and third types of mine lightning rod to prevent the nearby metal or electrical and electronic systems Line counterattack should meet the requirements of the distance is not yet in place, this proposed GB50057-2010 relevant provisions of the proposed changes for the relevant reference. The issue of separation distance continues to draw the attention of relevant parties. Many scholars abroad [1-4] have done more researches on the problem of separation distance, and the research literature about separation distance in China is relatively few.
