摘　　要：为防止雷击电流流过独立接闪杆时产生的高电位对被保护的建筑、设备金属部分发生反击,应使独立接闪杆与建筑、设备等保持一定的空气间隔距离。针对该间隔距离,国家和行业出台了一系列不同的标准。为保证独立接闪杆的防直击雷效果,同时防止反击,本文对现有国内外标准相关条款进行梳理和对比,在分析各标准差异原因的基础上,提出牵引变电所亭独立接闪杆空气中间隔距离的选择原则。In order to prevent the high potential generated when the lightning current flows through the independent lightning rod from back flashover on the metal parts of the protected buildings and equipment,a certain air spacing shall be maintained between the independent lightning rod and the buildings and equipment.With regard to the air spacing,a series of different national and industrial standards have been issued.In order to ensure the anti-direct lightning effect of the independent lightning rod and prevent the flashover,collation and comparison are made for the existing domestic and foreign standards,and the principle for selection of the air spacing between independent lightning rod and protected object in substation and post is put forward on the basis of analyzing the reasons for the differences of various standards.
