摘要
雷击通信铁塔引起的地电位反击极易造成机械室内信号设备大面积损坏,为提出具有针对性的雷电防护优化措施,需开展通信铁塔及邻近信号机械室雷电暂态过程量化研究。本文构建包含通信铁塔与信号机械室在内的雷电冲击缩比试验平台,采用控制变量法开展不同冲击电压等级下通信铁塔及机械室地网地电位以及多种接地体雷电流暂态试验,定量分析地网电位抬升以及雷电流的分流情况,进一步揭示铁塔地网电位向机械室地网的耦合传播规律。
This paper constructs a lightning impulse scaling test platform including the communication tower and signal machinery room,and conducts transient tests on the ground potential of the communication tower and machinery room under different impulse voltage levels,and on the grounding body lightning currents in order to quantitatively study lightning transients of the communication tower and adjacent signal machinery room.The rise of ground potential and the diversion of lightning currents are quantitatively analyzed,and the coupling propagation law of tower ground potential to machinery room is further revealed.
