自动气象站观测场防雷接地制式的技术分析

摘要

Based on the common earthing system of a automatic meteorological station in Jiangmen, the data collected from site and lightning position indicator were applied into the transient overvohage formula to calculate the transient overvoltage value from the wind speed sensor, collector, transmitter under different lightning current amplitude. The calculated value and equipment pressure value was compared to find out the basis to choose the two independent system or shared system.%以江门市某自动气象站共用地网为例，把现场采集的数据和从广东省闪电定位仪获取的数据巧妙运用到计算暂态过电压公式中，分别计算了风向风速传感器、采集器、变送器在不同雷电流幅值下的暂态过电压值，并把此值与设备耐压值进行比较分析，最后得出两地网选择独立还是共用依据。
