安装避雷针，是按照国家的《防雷接地验收以及施工规范》进行的，一般的电厂的主要避雷针是在烟囱上面，其覆盖面积首先能够达到周围的要求；
厂房的避雷针安装，是考虑雷雨天气避雷针和人体的安全距离考虑的。
希望能帮助到你

你好，因为厂房里面有很多的机械设备，相当于一个巨大的导电体，如果有雷电击中，巨大的电流会瞬间穿过设备，有可能会引起设备的损坏，所以防雷工程是必须要安装的。希望我的回答能够给您带来帮助。

防雷接地的原因:
为了防止雷电的危害而进行的接地，叫做防雷接地。防雷接地作用不言而喻，不接地就无法对地释放雷电流。规范的利用建筑物基础和主体钢筋做接地极和引下线以及人工接地装置、接闪器的安装作了具体要求。设计对防雷接地阻值都给出了参数，接地体和引下线完成后要测试，接闪器完成后整个系统才能测试。人工接地引下线要顺直，不存在死角，引下线金属保护管要与引下线做电气联通。避雷器带形成等电位可防静电危害。人工接地装置接地体间距不小于5m是为了降低接地体屏蔽作用。

防雷装置的类型、作用、人身防雷措施:
防雷设备有避雷器(管型避雷器、阀型避雷器和氧化镑避雷器)用于电气设备防雷。当线路受雷击时，避雷器间隙被击穿，将雷电引入大地，这时进入被保护设备的电压仅为雷电波通过避雷器及其引线和接地装置产生的“残压”。雷电流通过以后，避雷器间隙又恢复绝缘状态，系统仍可正常运行。
避雷针用于建筑物和一般设备防雷使用，当遇到直接雷击时，避雷针能够安全的将雷电流引入大地，保护建筑物和设备。
