雷电防护是为保护建筑物、电力系统及相关设施免受雷电损害的技术体系，通过搭接、传导、分流、接 地与屏蔽五项核心措施构建综合防护系统，形成包含外部防护、过渡防护和内部防护的有机整体。外部 防护，由接闪器、引下线、接地体组成，可将绝大部分雷电能量直接导入地下泄放。过渡防护，由合理 的屏蔽、接地、布线组成，可减少或阻塞通过各入侵通道引入的感应。内部防护，由均压等电位连接、 过电压保护组成，可均衡系统电位，限制过电压幅值。 雷电防护的组成部分 内容概要：近年来，我国雷电防护市场规模持续扩大，呈现出稳定增长趋势。数据显示，2020年中国雷 电防护行业市场规模达到100亿元，到了2024年中国雷电防护行业市场规模增长至160亿元，年复合增长 率为12.5%。这一方面是雷电灾害频发，对人民生命财产安全构成威胁，促使社会各界对雷电防护的重 视程度不断提高；另一方面，国家政策的大力支持，如2025年新修订的《防雷减灾管理办法》，为雷电 防护行业提供了良好的发展环境。此外，科技的进步，新兴雷电防护技术的研发和应用，提高了雷电防 护效果，降低了成本。 相关上市企业：中光防雷（300414）、科安达（002972）、汇源通信（0005 ...
