摘要
首先建立了雷电流的模型,并对雷电流的时域和频域特征进行分析,通过计算典型雷电流对车载通信系统电源线上的感应电压,进而确定了带有天线的车载通信系统防雷区域以及相应的浪涌保护器(SPD-Surge Protective Device)的通流量、残压等相关技术指标,并对SPD的电路以及安装进行了相应的设计。
The paper developed the model of lightning current firstly, then analyzed its time and frequency domain characteristics. By calculating the indirect voltage induced by typical lighting in power lines of communication vehicle system, it was determined lightning protection zones for communication vehicle system with an- tenna and corresponded technology factors, such as permitted current magnitude , remnant voltage of SPD (Surge Protective Device), then the circuit and installation of SPD were designed.
