摘要
雷击通信铁塔会导致铁塔地网电位瞬时剧烈升高,对邻近的信号机械室地网形成“地电位反击”。由“地反击”导致的信号机械室故障往往影响面积较大,恢复时间较长,已成为铁路信号领域面临的一大难题。为探究通信铁塔地网雷电地电位对机械室地网的耦合途径,设计一种信号机械室地网雷电暂态试验方法并在现场进行应用。
The ground potential rise(GPR)of communication tower caused by lightning strikes can transfer to adjacent equipment room.The GPR transfer leads to large impact area and long recovery time for equipment room,which becomes a major problem in the fi eld of railway signaling.In this paper,the lightning transient test method for the ground grid of signaling equipment room is designed and applied,in order to research the coupling way of ground potential between the communication tower and the equipment room.
