雷电浪涌对直流电源冲击效应的实验研究

摘要

直流电源是雷电进入电子系统的主要途径。为了研究雷电浪涌对直流电源的冲击效应，进行了雷电浪涌对直流电源的注入实验，发现雷电浪涌对直流电源有很大的干扰和破坏作用，并在实验基础上，提出了有效的防护措施。%DC power is the chief way in which thunder enter the electric system. In order to study thestriking effects of thunder surge to DC power, we made the inpouring experiments of thunder surge to DCpower, and found that thunder surge can disturb and destroy DC power. Based on the experiments, the pa-per puts forward the effective protection steps.
