易燃易爆场所独立避雷针检测方法

Examination method of independent lighting rod in flammable and explosive place

结合目前易燃易爆场所防雷装置的实际现状,根据独立避雷针的工作原理,提出了易燃易爆场所独立避雷针的检测技术和方法,指出独立避雷针应该计算它到被保护建筑物及其有联系的管道、电缆等金属物之间的安全距离和有效保护范围,检测接地电阻值,应具备良好的防腐、焊接效果,该检测方法为各级防雷检测机构或单位自检提供了借鉴。

Combining the actual present situation of lightningproof devices in flammable and explosive place, and according to the work principle of independent lightning rod, the examination technology and method of independent lightning rod in flammable and explosive place were proposed. For the independent lightning rod, it was pointed out that the safety distance and effective protection extent from the rod to the protected buildings and related metallic things such as pipeline and electric cable should be calculated, the earth resistance should be examined, and the well antiseptic and welding effect should be provided. This examination method provided reference for lightningproof examination organizations in all levels and the self- checking of relevant unit.
