摘要
单个或是常规气象观测场自动气象站的数据线缆不可避免地处在可能的雷电电磁感应场中,磁场的屏蔽很难,数据线的走向与磁感应场的关系密切,文中理论估算了雷电磁感应场对不同走向数据线的影响,指出了基本的对策;同时对抑制雷电波的防雷通道设计提出建设性的看法;结合实践,给出了数据线进入工作室的基本布局。
Data cable of automatic weather station in single or normal meteorological observation field inevitable be placed in the environment of lightning electromagnetic induction field. Ifs difficult to shield magnetic field. It has a close relationship between data cable towards and magnetic induction field. This paper academic estimates the influence of lightning electromagnetic induction field to the different data cable towards and points out basic counter plan. It also advances constructive opinion to the defence of lightning wave thunder proof passage design. This article combines with fulfillment and gives basic layout of data cable getting into workroom.
