摘　　要：随着铁路信号技术的不断发展和更新,电子设备广泛应用,信号设备防雷技术已不是过去狭隘的雷电防护,更是雷电及电磁兼容防护技术,铁道部投入大量资金进行防雷综合整治,但现场个别站仍存在不足,希望通过这起防雷单元故障分析引起重视。With the development and renewal of railway signal technologies, electronic equipment is widely used, and lightning proof technique for signal equipment is not limited to lightning protection at all and has evolved into lightning and electromagnetic compatibility protection technology. The Ministry of Railway has put huge amount of investment in comprehensive renovation against lightning protection but inadequacy of lightning protection still exist a few of stations. We hope that the fault analysis of the light- ning protection unit could arouse serious attention.
