煤层气发电站直击雷防护技术应用

Application of Direct Lightning Protection Technology in CBM Power Station

重点对煤层气发电站中的抽采泵站防雷采用不同形式接闪器进行分析,并根据实际案例进行分析验证,得出在瓦斯泵房面积较大的情况下,可优先考虑选择4支等高接闪杆作为防雷保护,若与防雷要求不相符,可选择2根接闪线。

The lightning protection of drainage pumping station in the CBM power station was analyzed with different forms of lightning arrester, and the analysis and verification were carried out according to the actual case. It was concluded that under the condition of large area of the gas vacuum pump room, 4 lightning rods with equal height could be selected as the priority for lightning protection, and 2 lightning rods could be selected if it was inconsistent with the lightning protection requirement.
