地空导弹阵地雷击风险评估

Assessment of lighting strike risk for ground to air missile position

针对地空导弹阵地占地面积大、地貌复杂、自然环境恶劣、雷击风险高的特点,提出了一种地空导弹阵地雷击风险评估方法.根据国家标准《建筑物电子信息系统防雷技术规范》,给出了年预计雷击次数和最大年平均雷击次数的计算公式以及雷电防护等级的计算方法.利用该方法对某型地空导弹阵地进行了雷击风险评估和雷电防护等级的确定,验证了该方法的有效性.

Aimed at the characteristics of the widely covered area, complex landform, harsh natural environmentand high lightning strike risk in ground to air missile position, this paper puts forth an assessment method oflightning strike risk for ground to air missile position. Calculation formula of both predicted annual times andmaximum annual mean times of lightning strike, and calculation method of lightning protection levels are given inthis paper, according toGB“Building Electronic Information System Lightning ProtectionTechnique Specification”.Then, the proposed method is used for an assessment of lightning strike risk and determination of lighting levelsfor a certain type of ground to air missile position, for verifying the effectiveness of this method.
