摘　　要：随着科技的发展,电子设备越来越多地应用于铁路防灾安全监控系统(简称防灾系统)。由于铁路防灾系统大多是弱电设备,很容易受到雷电影响,而雷电是每年都会发生的自然现象,因此为保证铁路运输系统的正常运行,有关铁路防灾系统的雷电影响分析与防护工作十分重要。通过对铁路防灾系统中风、雨、雪监测点进行调查与研究,采用增加隔离防护装置的措施,可提高设备的可靠性,降低设备因雷击而损坏的程度。Technology advancement has brought about the increasing application of electronic devices to railway disaster prevention and safety monitoring system （or disaster prevention system for short）. Given that most of such devices are powered by weak electricity, they are vulnerable to the influence of thunder and lightening which tend to be an unavoidable natural phenomenon. In this sense, the influence analysis of thunder and lightening and the implementation of protection measures are of great significance to the prevention system~ which helps ensure the smooth operation of the railway system at large. The paper carries out research on and studies the monitoring point for wind, snow and rain of the railway disaster prevention system. And the results show that the adding of insulated protectors help improve the reliability of the system and mitigate the potential damages triggered by thunder.
